Run to failure or run to safety?

The Vice President of the USW, a body representing workers has mentions that "the oil industry's run to failure mentality concerning equipment gets worse every day. He also said that the union will not give up its campaign to have enforceable health and safety language.He added that "It's all about money. The refiners run the units longer to sell as much product as possible."
Mr Rafael Moure Eraso chair of the US Chemical Safety Board said that "We see a growing crisis of safety in the oil sector." He cited the Gulf rig disaster as well as recent explosions and fires at onshore production, processing, and refining facilities.
Mr Beevers said that the industry needs to bring back shorter periods between turnovers, which are times when a refinery is shut down for maintenance.
Mr Moure Eraso said that operators have told him that turnarounds that normally occur every two to three years are happening now every four to five years. They have said that broken equipment is not immediately addressed and workers are told to work around the problem".

This is a classical production Vs Safety question. How do you decide the intervals between planned shutdowns for maintenance? Of late, due to market pressures, many organisations are increasing the duration between shutdowns.In the interest of process safety, this decision has to be made very carefully after weighing all options, including ageing of the plant,process incidents and maintenance data.

Overfilled rail tanker "burps" isobutane!

An incident has been reported in the US where an overfilled rail tanker was overfilled and it appears that the safety valve lifted momentarily, causing what observers report as a burp! A passerby called 911 and the excess isobutane was transferred to a road tanker. Many of the chemicals in India are transferred in rail tankers. Ensure that they are not overfilled. It will not show up immediately but as the day warms up, there is a likelihood of overpressurising of the tanker.

Process safety - Its lonely at the top!

Imagine what Tony Hayward the erstwhile CEO of BP must have gone through following the oil rig accident. In India, prosecutions of the "Occupier" are on the increasing trend. An article mentions that "There are few places on earth more lonely than the space occupied by a corporate executive who is potentially responsible for a process safety mishap resulting in significant injuries to property, the environment and people. Often, support for such executives at that time can be seen by governmental authorities and the public as a failure of the corporation to take responsibility for the consequences of the catastrophic incident. On the other hand, abandoning such individuals in their time of need—particularly as they are subjected to regulatory and criminal investigations and the initiation of civil lawsuits—is seldom in the best interests of the corporation.
The best time to consider these issues is long before the adverse critical incident occurs. Most state laws require indemnification of employees charged with wrongdoing during the course of their employment, as long as those employees are ultimately exonerated. In addition, broad corporate indemnity provisions and directors and officers (D&O) insurance policies are available to protect such employees".

The human consequences of a fire accident

Many chemical plant personnel take work permit systems for granted. It just becomes a piece of paper after some time. From time to time a harsh reality check is required for people to understand the dangers of hot work and working with flammable materials. I came across an article which is an amazing tale of a fire accident survivor who is now a professional speaker. His name is Spencer Beach and he has written a book about his ordeal. He was gravely injured in a fire accident with a solvent/thinner. The photo attached in the article is not for the lighthearted. But I felt that people should realise the human impact of a fire accident. Read more of this article in this link.

Running blind - the dangers of reactive chemistry

There is a lot of ignorance about reaction hazards in the batch processing industry. As long as incidents do not occur, operators of reactors that handle reactive chemicals seem to think that it will never happen to them. The fallacy is that we seem to think that big reactors are safe as they look strong! It is the other way around in reactive chemistry! If you do not know the sizing basis of your cooling/condensing systems, your vent/scrubber systems and details of the reactions you are handling, you are running blind! Read a basic article on dangers of reactive chemistry in this link.

OSHA warns power plant operators on hazards of natural gas purging

Hazardous chemicals lying in Indian Ports

Outlook magazine has brought out an article on the hazardous chemicals lying in various Indian ports. Recently, chlorine gas had leaked from old cylinders in the Mumbai Port. The article mentions that 92.4 metric tonnes of methyl monomer, a toxic compound used for making plastics, has been lying at the New Mangalore port since June this year. The article also mentions that more than 203 metric tonnes of various kinds of hazardous substances lies scattered around Mumbai port; another 200 metric tonnes lies awaiting disposal at the Jawaharlal Nehru Port Trust.

Narural gas pipe explosion inUSA

A natural gas pipelines explosion in the US town of San Bruno has devastated the area.A news article mentions the following:
"The force of the explosion was large enough to level the area immediately around the blast’s epicenter. NTSB teams, as well as local investigators, are combing through the blast zone looking for evidence that will allow them to determine the cause. The primary problem with useful evidence in a fire investigation is the simple fact that much of it burns up during the event. Therefore, investigators have to look beyond the physical evidence to gain insight as to what really went wrong. Investigators are looking at the maintenance and safety records of the gas main in question, to see if red flags appear. They are also looking into the personal records of all individuals who worked on that particular section of pipe. This includes, drug problems and the general performance records of key individuals involved in the pipe’s maintenance.
Once the gas main has been designed and stringent regulations have been met, it’s up to qualified contractors to safely install the pipe. Lengths of pipe are specially welded together by trained pipe welders and this presents a potential problem. Anytime there is human interaction in the process of building something, the question arises; did that individual do their job correctly? The same holds true for the entire construction process. There have been numerous construction related disasters that were caused by insufficient materials, poor safety regulations and cost cutting. While there is no indication that these forces are at work here, the question still arises, was human error the driving factor in this accident? Mathematically, the odds are sadly in favor of human error".

BP oil rig disaster internal investigation report

BP has released their internal investigation report of the oil rig disaster in the Gulf of Mexico. The report is obviously an initial investigation on the causes and does not go into why the failures occurred. This is stated by BP as follows:
It may also be appropriate for BP to consider further work to examine potential systemic issues beyond the immediate cause and system cause scope of this investigation. The summary of the report findings are given below:
1. The investigation team concluded that there were weaknesses in cement design and testing, quality assurance and risk assessment.
2. The investigation team concluded that hydrocarbon ingress was through the shoe track, rather than through a failure in the production casing itself or up the wellbore annulus and through the casing hanger seal assembly.
3.The investigation team has identified potential failure modes that could explain how the shoe track cement and the float collar allowed hydrocarbon ingress into the production casing.
4.The Transocean rig crew and BP well site leaders reached the incorrect view that the test was successful and that well integrity had been established.
5.The rig crew did not recognize the influx and did not act to control the well until hydrocarbons had passed through the BOP and into the riser.
6.If fluids had been diverted overboard, rather than to the Mud gas separator (MGS), there may have been more time to respond,and the consequences of the accident may have been reduced.
7.The design of the MGS system allowed diversion of the riser contents to the MGS vessel although the well was in a high flow condition. This overwhelmed the MGS system.
8.The heating, ventilation and air conditioning system probably transferred
a gas-rich mixture into the engine rooms, causing at least one engine to overspeed, creating a potential source of ignition.
9.Through a review of rig audit findings and maintenance records, the investigation team found indications of potential weaknesses in the testing regime and maintenance management system for the Blow out presenter (BOP).

Point no. 8 is a repeat of the ignition source in the BP Texas city refinery explosion where a pick up truck took in vapours through its air intake and triggered the initial explosion.Are we learning from our incidents?

The BP oil rig disaster

A presentation in the Global maritime Congress 2010 by Clay Maitland about the cause of the BP oil rig disaster mentions the following:
What were the underlying causes of the disaster?
• Complacency and routinism; the tendency of those within a large organisation to avoid testing established policies.
• “Bean-counteritis”; a failure to examine constraints on risk management budgets.
• Collectivism; a conviction that existing company policy is, by definition, the best that could possibly be. In American parlance, this is often called “drinking the company Kool-Aid.” It entails a rejection of rigourous analysis of internal management systems,and their appraisal for possible deficiencies.
• A failure, from top to bottom, to subject these systems to outside scrutiny, in the manner of the International Maritime Organisation’s Member State Audit Scheme.
• A tendency to stigmatise concern for the environment as something repugnantly radical, “Greenpeace Socialism”, “tree-hugging”, etc.
• Most significantly, the failure to establish a risk control or safety awareness mindset at all levels of the corporate hierarchy,particularly at middle-management levels, and to effectively offset a “get it done, at the lowest possible cost” attitude at the “coalface”.

Fireworks factory blast in Malta

An article in the Times of Malta mentions about a fireworks factory blast. the reasons mentioned are very true for the firework factories in India also. The fireworks manufacturing industry is unorganized and employs labourers who are not literate. As part of Corporate Social responsibility, the larger players in the chemical industry in India need to assist these unorganised and small scale players to improve their safety while handling hazardous chemicals.

Caustic soda and process safety

Caustic soda (sodium hydroxide) is a commonly used chemical. Its main uses are in the manufacture of pulp and paper, alumina, soap and detergents, petroleum products and chemical production. Other applications include water treatment, food, textiles, metal processing, mining, glass making etc.
Caustic soda is a also a basic feedstock used in the manufacture of a wide range of chemicals. The Dow Chemical Co. has useful data on process safety aspects related to storage and its design.

Bhopal and BP – different approaches – different people

An article compares the difference in approaches between the Bhopal Incident and the recent BP oil rig disaster. “Both Union Carbide and BP received clear warning that their operations in Bhopal and Horizon Deepwater were not well managed and therefore had significant safety risks. Over 10 years before the actual catastrophe,a 1973 Union Carbide report signed by the Warren Anderson himself, highlighted that the unproven nature of Bhopal’s technology. In a 1982 safety review, Union Carbide’s own experts also emphasised the serious risk of substantial leaks of “toxic materials” at Bhopal. BP too received adequate warning of impending problems at Horizon Deepwater. A number of internal investigations alerted senior BP managers that safety and environmental rules at Horizon Deepwater were not being properly adhered to.”

Are your back up systems really capable of back up?

A report of an incident in an aircraft which suffered a cabin depressurization in flight and had to make a rapid descent reinforces the need to ensure your back up systems are working and reliable. It appears that the flight was operating with a single compressor feeding both the cabin pressurisation systems. Due to the high demand, the air temperature and pressure were higher. However the aftercooler was not cooling the air sufficiently due to a cooler fan problem. This led to the compressor shutdown on high air temperature and subsequent loss of cabin pressure.

Fail safe or Fail unsafe?

The blowout preventer that failed in the BP oil rig disaster was meant to be fail safe. But why did it fail? There is an excellent video from the NY Times explaining what could have gone wrong. Layers of protection analysis is supposed to find these weak links, but in my experience, LOPA depends heavily on the time available for the team to do it, the experience of the team and finally what is done with the recommendations. Watch the NY times video in this link.

Vacuum hazards - Another one bites the dust!

I came to know yesterday of an incident in India where a pressure vessel collapsed due to vacuum. The hazards of vacuum in vessels that are not designed for them is great. Please see my earlier post on the subject.

Dangers of Solvents inside confined spaces

The CSB has released an excellent video of 5 deaths occurring in a confined space in a hydroelectric plant in USA. The workers were using MEK (Methyl Ethyl Ketone) , a highly flammable solvent inside a confined space when it caught fire most likely due to static electricity. The CSB report has raised three points:
1.The contractor selected for the job was selected based on the lowest quotation even though his safety record was poor.
2.The current OSHA standard for confined spaces (CFR 1910.146) does not specify what additional precautions must be taken for working in a permit-required confined space with a potential flammable atmosphere, nor does it limit entry based upon measurable criteria such as a specific maximum percentage of the LFL, even though OSHA defines an atmosphere as hazardous when it exceeds 10 percent of the LFL.
3.There was no proper emergency plan for the work conducted
In India, the problems with contractors are numerous. Public sector units are required to go for three quotations and submit the job to the contractor with the lowest quote. This is also followed in some private players. Contractors are not trained adequately on the hazards of confined spaces. I know of at least three similar incidents in India where contractor employees died when flammable solvents caught fire inside a confined space.

Process Safety - Bhopal and BP- I Don't know!

It is eerie. 25 years ago after the Bhopal gas leak occurred, the then police chief met the security chief of Union Carbide and asked him what had leaked and what was the antidote. The answer was "I don't know". Cut to 2010. A news article mentions that "BP executives told U.S. investigators they didn’t know who was in charge of the doomed Deepwater Horizon rig in the Gulf of Mexico or who made key decisions before the vessel exploded in April, killing 11 workers and spewing millions of barrels of crude into the sea". The testimony from Wells, the highest-ranking BP executive to appear before the joint U.S. Coast Guard-Interior Department panel probing the catastrophe, frustrated Hung Nguyen, co- chairman of the panel, who said no one from BP has accepted responsibility for actions that led to the disaster.

“We’ve had so many vice presidents of drilling come before us, I can’t even keep track,” said Nguyen, a Coast Guard captain. “A lot of them answered ‘I don’t know, I’m not responsible’ for this or that. If everybody’s in charge, nobody’s in charge, is that correct?”

One interesting point mentioned by a manager was that he could not read the well cementing procedure in his blackberry due to its small size! Now did a blackberry cause the disaster?!!!!

Process safety makes business sense!

A news item mentions that BP will pay a $50.6 million fine, negotiate another $30 million in penalties imposed by the Occupational Safety and Health Administration (OSHA), and undertake $500 million worth of repairs and upgrades at the Texas City plant where an explosion took place in 2005.
Under the agreement, BP will pay the $50.6 million fine and work out with OSHA how much of an additional $30 million in fines it should pay for other violations the agency has found on subsequent inspections at Texas City. BP will also spend $500 million to fix "process safety" problems it ignored on 28 separate plant processes.

Traces of phosphine gas reported emanating from MV Chitra

News reports indicate that traces of phosphine gas emanating from the damaged MV Chitra which was involved in a collision with another ship at Mumbai Port is delaying salvage efforts. The ship was reportedly carrying Aluminium phosphide, which is used as a pesticide and rodenticide. Aluminium phosphide on reaction with water generates phosphine. Wikepedia reports the following on phosphine:Phosphine gas may form explosive mixtures with air and can self ignite. The gas is heavier than air. When phosphine burns, it produces a dense white cloud of phosphorus pentoxide – a severe respiratory irritant.[8]
Also, Wikepedia reports the following about Aluminium phosphide:
In October 2002, Sir Derek Bibby, 2nd baronet and great-great-grandson of the founder and past chairman and president of the Bibby Line shipping company, aged 80 and terminally ill with leukaemia, committed suicide by consuming aluminium phosphide - the poison, hours later, caused his body to emit dangerous fumes forcing the evacuation of the hospital department where his body was being held.[4]
In February 2009, two children died in Jeddah, Saudi Arabia after a neighbouring house was fumigated with aluminium phosphide.[5]
In February 2010, two sisters died in Layton, Utah after the area around their home was treated with fumitoxin to get rid of rats. The two sisters, ages 4 years old and 15 months, died just three days apart from each other after experiencing identical symptoms.[6]

Dangers of turbine overspeed

In 1983, I was nearly killed when a 100 HP steam turbine driving a naphtha pump catastrophically disintegrated due to overspeeding caused by the choking of the pump suction strainer. I was standing near the turbine when I heard it suddenly speeding up. I managed to hide myself behind a concrete pillar before the turbine disintegrated. The mechanical overspeed trip malfunctioned and did not work.
Understand that rotating equipment have speed limits and make sure that your overspeed trip mechanisms are working properly.
I was saddened when I came across a news item about an incident in 2001 when a person was killed due to an overspeed of a turbine when it was being tested.

Dangers in silos or bins

OSHA has reportedly fined a grain handling facility fined $721,000 after a worker was engulfed in a storage bin. The OSHA news item reports as follows:
"OSHA fined Cooperative Plus Inc. $721,000 after a near tragedy in February, when a worker in a storage bin was trapped in soybeans up to his chest in 25 degree weather. The worker was ultimately rescued after a four-hour ordeal. OSHA issued 10 citations against the Burlington, Wis., farmer-owned cooperative after inspectors concluded that the employer had willfully disregarded safety requirements by exposing workers to the risk of being engulfed and suffocated in grain storage bins. Two of the citations were for multiple egregious violations for failing to provide workers entering grain storage bins with body harnesses and lifelines and failing to provide an observer while other workers entered the grain bins. See the news release for more information about this case and OSHA's new grain storage bins fact sheet* for more information on engulfment hazards".
Unfortunately, this type of incident happens with disturbing frequency in the grain handling industry. In the last 10 months, OSHA fined two grain handling facilities more than $3 million after separate incidents in which a 17-year-old who had just graduated high school and a 52-year-old husband and father were engulfed and suffocated in grain storage containers. Last month, two Illinois teenagers (ages 14 and 19) were suffocated after being engulfed in a grain bin they had entered. A third young worker was hospitalized after being trapped in the bin for 12 hours.

OSHA has published a useful fact sheet on the hazards in silos, which is given in this link

Process Safety Management - Its not all technical!

A huge wave of interest in Process safety generally occurs after a major incident. The Jaipur oil fire,the BP oil spill, the Bhopal gas disaster court verdict and other incidents have sparked a huge interest in process safety.The management of process safety does require a lot of technical competence. However the MANAGEMENT of Process Safety requires just that - its about people. Just pause back a bit - Bhopal - 1984.... reasons for the incident - cost cutting without assessing risks, ignoring warnings,poor emergency response planning... the list goes on. One or more of the same reasons keep coming up for the recent incidents also! Technology has changed rapidly and we have Safety Integrity levels, redundant systems, more reliable equipment etc etc but still accidents happen. Why? Because wrong decisions are taken by a human being. Whatever administrative frameworks we design and provide for risk based process safety, one day a human being is going to override the administrative framework and take a decision that ultimately causes an incident. I was jokingly mentioning to participants of a process safety seminar that as long as people exist, the job of a process safety management consultant will be in demand!Have a safe day!

6 workers drown in Lucknow Ketchup Factory

Alas, it's happened again. A worker fell into a ketchup tank in a ketchup factory in Lucknow, India. In the process of trying to save her, another 5 co-workers lost their lives. In any confined space entry, the job of the man watch is to call for help if anybody inside needs to be rescued.

OSHA will not ban Gas Blowing of pipelines

A news article in the Wall street journal mentions the following: "OSHA administrator David Michaels, in a news briefing Thursday, said his agency is putting the power industry "on notice that it is inherently dangerous" to conduct gas blows and he said the industry "must assure worker safety," if it persists.
But he said he wouldn't put an emergency order in place that would prohibit gas blows until the agency studies it further. "We would love to be able to ban it, but we can't," he said.

The chairman of the Chemical Safety Board, which investigated the incident, said Thursday that OSHA's response to the Kleen Energy explosion was insufficient despite it being even though it is the third-largest recommended fine in a single accident in agency history.
"I believe there should be an emergency response to an emergency situation," said Rafael Moure-Eraso, the board's chairman, a former academic.
After the board's probe, big equipment makers including General Electric Co. and Siemens AG said they would tell their customers to substitute compressed air or nitrogen for natural gas. Utility American Electric Power also said it would avoid the procedure based on the board's findings and its own analysis".

Fire in chemical godown at Bangalore

Thanks to Mr Sritharan for sending the following information:
Please find the news on the fire which broke out in a chemical (solvents and thinners) storage godown in Shivajinagar, Bangalore. The godown was located in a densly populated commercial and residential area. As usual the fire dept says that the godown did not have the necessary license only after the incident and do not have proper procedures to check out these violators.
Also the news reports that the local people started pouring water as soon as they saw the fire without knowing that some water sensitive chemicals can indeed aggrevate the situation. Only the trained fire fighters should handle these types of chemical fires.

Where does the buck stop in Process Safety Management?

I have been viewing the numerous developments in process safety in India with great interest. The Indian Chemical Council has taken a big interest in Process Safety and is collaborating with the Center for Chemical Process Safety of the US. While it is good that a great awareness of Process Safety Management is being created in India, where does the buck stop as far as Process Safety Management goes? The composition board of directors of many chemical organisations in India are changing with fewer and fewer companies having technically qualified people at the helm.With due respect to the immense experience that other directors bring, I see an erosion in technical competence at the board level. While risk based process safety does bring in process safety metrics to the board's attention, it needs technical competence to analyse these metrics. Ultimately, the culture of the organisation trickles down from the decisions that the board takes. What is the long term solution to this issue? No amount of management systems is going to avoid a catastrophic incident. They will warn you adequately before a big incident happens, but unless someone at the board level is competent to analyse these warnings, you cannot prevent the incident. It boils down to basic human behaviour. Is a director on the board going to pay more attention to what another technically competent director is saying, or to the various process safety metrics he sees displayed but may not fully understand? I leave it to you to decide...

Drum bursting hazard - readers innovation


In my earlier post , I had mentioned an incident on the dangers of pesticide technical drums bursting when placed in a hot box or steam heated bath. A couple of readers Mr P.Kadhiravan and Mr P.Thulasiraman of Coromandel International Limited have devised a simple pressure relief system for the technical drums which they place in a steam bath for melting. Their pressure relief device is screwed on to the drum in the bung area after removing the drum cap. A photo of their innovation is shown. Kudos to them! And thanks to them for sharing this information.

Share your incidents!

I thank readers of this blog for their continued support. I request readers to send in short descriptions of process incidents they know, to me at bkprism@gmail.com for publication in the blog. I will give the reader credit for the input. The company's name need not be mentioned.Thanks in advance!

Enforcing Process Safety Management

I always wonder that even in the US where PSM is mandatory and companies face stiff fines, there are always violations taking place. Recently OSHA has proposed to fine a seafood company a total of $279,000, for deficiencies in its process safety management program. "The inspection identified other PSM hazards that resulted in 12 serious citations, with $84,000 in proposed fines. These conditions included failing to update process safety information, conduct an incident investigation of a January 2001 ammonia leak, certify or evaluate the PSM program every three years as required, establish and implement procedures to maintain changes in the process, and provide and document employee training".

Engineering control to avoid deaths

The recent train accident at Sainthia station when a speeding train rammed into a stationary one,has raised many questions.An excellent article in Forbes India magazine describes the various engineering controls that are available to prevent such accidents. The article mentions that "There is a range of technological solutions that can remove the scope for human error and make the system fool-proof. The Indian Railways have experimented with a range of solutions to improve its safety record, but none of them has been scaled up nationwide either due to the lack of budget or simply because the powers-that-be had other priorities. When asked, a senior executive in the Indian railways, in charge of technology implementation, prefers to maintain a stoic silence on the issue. Former railway officials, however, are far less sanguine. “The job must be ruthlessly done and the management must not shy away from shedding blood,” says a former Chairman Railway Board who did not wish to be quoted".
In the chemical process industry also, I observe many cost cutting initiatives affecting engineering controls. As long as nothing happens, nobody dies!

Safety valves and runaway reactions

I was participating in a HAZOP study of a reactor where a runaway reaction was possible.There was a serious discussion about the reaction kill system, when one of the participants asked what the operators will do if a runaway reaction occurs. The operations chief who was participating immediately answered - run away!He had witnessed an actual runaway reaction in which the reactor started rumbling, gaskets blew, safety valve lifted,and the operators ran away. Know the design basis of your safety valves. This is important for management of change and for writing operating procedures.

Strong oxidiser causes oil pipeline blast

A new report indicates that the pumping of a wrong chemical into a pipeline that had just completed unloading of crude oil. The report states that "An investigation has found that a desulphurising chemical was mistakenly pumped into pipelines after a tanker had stopped unloading crude at the port city of Dalian last Friday, triggering the explosion, the State Administration of Work Safety said in a statement posted on its website.The 0.9-meter-diameter oil pipeline exploded at 6 pm on July 16, triggering a smaller adjacent pipeline to also explode, the statement said.
The explosion occurred as workers from the Shanghai-based QPRO Inspection and Technical Service. continued to inject desulfurizer into the pipeline after the 300,000-ton tanker had finished unloading its oil at 1 pm.
Produced by the Tianjin-based Huishengda Petroleum Technology, the desulfurizer was strongly oxidizing, according to the statement".

Management systems - on paper or by commitment?

I have always been of the view that management commitment is something that cannot be spelt out on paper that we can expect top management to follow. Paper based management systems will remain on paper unless top management throws its full commitment behind it. Commitment is intangible. It is seen at the ground when decision are taken by managers that have an effect on process safety.Top management are also human. They also can succumb to pressure from stakeholders. I will give you an example. A leading chemical manufacturer I visited had all management systems in place and certifications.During my field visit, I observed a safety valve on an equipment isolated as it was prematurely lifting (popping) and causing loss of production. This safety valve had no redundancy. When I spoke to the Plant manager,he mentioned that all systems remain on paper and when the actual decision on safety is to be taken, he is expected to take action to maintain production targets!
Interestingly, BP, after the recent oil rig disaster itself is of the opinion that management systems alone cannot control risks. I am quoting from the article: BP said "there can be no assurance" that a major global deployment of its in-house Operating Management System would identify all risks or provide information on the right actions to take when things go wrong. The rollout will be complete this year.OMS was introduced as a key safety step following the large explosion in BP's Texas City Refinery in 2005, which killed 15 workers and injured 170. The system is being implemented across BP operations in locally-tailored modules, following global standards. It is now in all US sites and will be rolled out by the end of the year to the remaining few sites elsewhere that do not yet have it.
The OMS system, described by BP as the "cornerstone" of its safety efforts, was developed by BP in-house, built around Microsoft SharePoint and Performance Point. It helps integrate local standards and management systems, set priorities, define processes and measure performance, and is accessible on BP PCs as well as mobile devices used by engineers on the rigs.
But yesterday BP said: "Even after implementation of OMS has been completed, there can be no assurance that OMS will adequately identify all process safety, personal safety and environmental risk or provide the correct mitigations, or that all operations will be in compliance with OMS at all times."

What is the solution to this problem? Top management should pay attention to external safety audits as they indicate things that may not be spotted by internal audit teams. I have also seen some managements asking the external auditors to tone down their findings. Now this is hara kiri!Here the moral ethics of consultants and auditors come into play. Whatever certifications or management systems the company employs, there must be a threadbare audit of decision making and management's tracking of safety management systems. Its only the acceptance of facts that will prevent an incident.

Spraying of pesticide in AC ducts - a possible cause of an incident

The Hindu Newspaper has reported that employees in a manufacturing unit had to be hospitalised due to the possible spraying of pesticides into an AC duct.The root cause is still being investigated. This raises a larger question of product stewardship. Pesticide Manufacturers in India do post all the warnings in their product but how do we ensure that they are all followed?

Hazardous waste facility explosion report

"A U.S. Chemical Safety Board (CSB) case study released today on the 2009 explosion and fire at the Veolia ES Technical Solutions L.L.C. facility in West Carrollton, Ohio, calls on the industry to improve safety standards covering hazardous waste processing, handling, and storage facilities. The Board also recommended that fire protection codes be revised to require companies to determine safe distances between occupied buildings and potentially hazardous operating areas.
The accident occurred on May 4, 2009, when flammable vapor was released from a waste recycling process, ignited, and violently exploded. The blast seriously injured two workers and damaged 20 nearby residences and five businesses. CSB investigators found that the north wall of the lab and operations building – where the victims were injured –was less than 30 feet from the waste recycling processing area where the flammable vapor was released.
CSB Chairman Rafael Moure-Eraso said, “This accident should not have happened. Our report notes that OSHA cited the company for inadequate attention to process safety management practices in the handling of flammable liquids. But in case of an accident, I believe it is absolutely critical that buildings at chemical facilities be sited safe distances from process equipment to maximize the safety of workers. We are making recommendations that would help ensure that operating areas with occupied buildings such as control rooms be sufficiently separated from process areas containing flammable liquids and gases that have the potential to explode.”

Labs are as dangerous as process plants

Do not ignore safety in laboratories when concentrating on process safety. Many incidents occur in labs and R & D facilities. An incident in an university lab killed a girl when the pyrophoric chemical she was handling ignited. Investigate any incident in the lab or R & D with the same focus as an incident in the plant.

Update on Phosgene hose leak incident

A news report indicates that OSHA has cited DuPont and proposes fines for the phosgene hose leak incident that killed one employee. It is also interesting to note that one of the factors for the leak was physical corrosion below the manufacturers sticker label on the failed hose.
"OSHA said DuPont failed to:
-Properly inspect piping used to transfer phosgene.
-Perform a thorough process hazard analysis for its phosgene operation.
-Train workers on hazards associated with phosgene.
-Thoroughly inspect all high-risk sections of piping used to transfer oleum.
-Properly install energized electrical conductors.
The agency issues a serious citation when there is substantial probability that death or serious physical harm could result from a hazard the employer knew or should have known about".

Gases can be deadly - Blast in coke oven

Thanks to Abhay Gujar for sending me this news to share with you.An explosion in a coke oven battery near Pittsburgh has reportedly injured 20 persons. "To make coke, coal is baked in special ovens for hours at high temperatures to remove impurities that could otherwise weaken steel. The process creates what's known as coke gas — made up of a lethal mix of methane, carbon dioxide and carbon monoxide".. Read more of the accident in these links:

Cabon Monoxide - a deadly gas

A recent incident in the Durgapur steel plant highlights the danger of Carbon Monoxide (CO). Carbon monoxide is produced in ammonia, methanol plants, in refineries and in blast furnaces. Any improper combustion of fossil fuels will also lead to the generation of CO. CO binds with blood hemoglobin to form carboxyhemoglobin. Carboxyhemoglobin cannot take part in normal oxygen transport, thus reducing the blood’s ability to transport oxygen. Depending on levels and duration of exposure, symptoms may include headache, dizziness, heart palpitations, weakness,confusion, nausea, and even convulsions, eventual unconsciousness and death.Recently in the newspapers, there have been incidents of fatalities in cars where occupants have kept the AC running when the car was stationary. Leaks in the exhaust system allowed CO to enter the passenger cabin thus killing occupants. Read the report of the incident at the Durgapur steel plant in this link.

Public perception of Process Safety in India

Thanks to the media and internet and the demographics of India, a large number of the younger Indian generation are aware of the hazards of chemical industries and the importance of process safety management. In fact, the Bhopal disaster court judgment has raised awareness about the hazards of chemical industries. What can industries,industry associations and the Government do about it? I have a one word answer - transparency. Transparency in conduct of operations, transparency in incident investigation and sharing of incidents, transparency in law enforcement, transparency in environmental assessment processes, the list goes on.... The transparency International website indicates that for 2009, India has a corruption perception index of 3.4 on a scale of 1 to 10 where 1 is the most corrupt. We are at the bottom of the pyramid here! What does this have to do with process safety? Though the chemical industry is making an effort to improve safety and the public's perception of chemical industries, it will take a huge effort to really change perception. With daily newspaper reports of Government officials being caught taking bribes, a life has no cost in India unless it belongs to an influential person.
The recent Mangalore air crash has brought about some changes in investigating aviation incidents in India. In a similar way, a Chemical Safety Board on the lines of the US CSB (www.csb.gov) needs to be formed. All major chemical accidents need to be investigated independently and the reports be made public through the net.Meanwhile I keep praying that another Bhopal does not take place in India.

Mnagement systems and Process Safety

The Indian chemical industry is on a path of vibrant growth. Many chemical manufacturing units recognize the need to manage process safety as the consequences of a chemical accident today are enormous. However, organisations also need to realise that management systems alone will not help. Getting certified to ISO 14001,OHSAS 18001 or Responsible Care etc cannot by itself prevent a disaster. It is the Management of these systems that will prevent one!By this I mean how does the top management utilise these systems to prevent a disaster? In many organisations in India I have observed that when a key top management person like the CEO changes,and a new CEO arrives,these management systems may go for a toss if the new CEO was not as focused on them as the previous one! How do we ensure continuity of effective implementation of systems? My answer is that profits should never override process safety and other management systems. This is easier said than done!

Chlorine Safety

The Aditya Birla company has a nice practical presentation on chlorine safety which you can access through this link.

Missing incident investigation deadlines

In many process safety audits , I keep observing that detailed investigation of incidents keep missing their deadlines. This speaks of the culture of the organization. When we don't learn from incidents, we will repeat them. I was reading a news item in Times of India which mentions about the investigation of the Mangalore air crash. I quote from the article " What happens when Directorate General of Civil Aviation (DGCA) officials violate their own rules? Nothing. It's been over a month and a half after Mangalore air crash and no preliminary investigation report has been released yet, though the country has a rule that puts a 10-day deadline for filing one. Little wonder, then that the rule concerning accident/incident investigation is hardly known in the aviation industry as it has almost always been violated.
If this can happen in the Indian aviation industry, I am worried!!!

Ticking time bombs!

The incident of old chlorine gas cylinder leak at Mumbai Port Trust raises a question. How many such ticking time bombs are still there? The Indian Gas cylinder rules are well written but I have observed that people give scant respect to gas cylinders. Domestic LPG cylinders being tossed about is one case. In the Mumbai Port Trust incident the FIR has been raised against "unknown persons". Isn't the port responsible for all hazardous cargo in its facility? I quote a NDTV news item "That is supposed to be an empty cylinder of chlorine, but sometimes you have residual chlorine which remains in the cylinder and that leaked out," explained Rahul Asthana, the Deputy Chairman of the Mumbai Port Trust.
How does one know it is empty unless it is confirmed? How did residual chlorine remain in the cylinders??
A friend of mine also points out that many chlorine cylinders are used in thermal power plants and municipal water treatment plants and that they store a large number of chlorine tonners. I am only reminded of Dr Trevor Kletz's statement " What you don't have cannot leak!"

BP Oil Spill - an interesting take

I read an interesting article in Forbes.com where the writer mentions the following:
"The job of senior executives (or politicians and regulators) is to think the unthinkable. While few risks truly justify a "never failing" attitude, those that do should follow my five reliability principles:
1. Multiple things must line up before failure can occur (catastrophic failures are extremely rare).
2. Junior management error is the most frequent root cause. Why protect against something that probably won't happen?
3. Very carefully control configuration changes. In BP's case the drilling rig was being disconnected at the time of explosion.
4. Look for unintended interactions between adjacent systems. For instance, unexpected freezing conditions prevented the first BP well cap from working.
5. Be very, very careful toward the very end of long-term projects. On the day of the BP explosion plaques were being distributed to employees for seven years of uninterrupted safety".

Point number 2 in which the writer mentions that Junior management error is the most frequent cause is linked to organisational culture. With the Indian workforce becoming younger and younger, I observe a shift in the Plant manager's perception of risk. They are becoming more blind to risk due to inexperience and lack of training, and conflicting signals from top management (Top management talks about safety but does not back up its actions with resources). A recipe for disaster!

Hot Work Accidents

25 years ago, I was witness to an incident where a new pipeline was being prefabricated by supporting it on a "empty" drum. Unfortunately the drum had been earlier used for draining naphtha from a vessel and still contained naphtha vapours. We were inside the control room (about 40 meters from the hot work) when the welder started welding two pieces of the pipe supported on the drum. The explosion could be heard inside the control room. The heavy pipe was lifted 15 feet into the air and fell on the welder killing him.
The basic precautions for hot work include a written work permit system, monitoring the work place for combustibles/flammables, ensuring that no flammable material enters the hot work area/equipment by proper positive isolation,containing the sparks from the hot work and proper training of both permit issuer and receiver. In many plants I visit, the operations and maintenance personnel think it is the job of the safety officer to check these points. You must understand that is the primary job of both the permit issuer and the permit receiver to check all these points before they carry out the work.Let us not kill more people.

Texas City to the Gulf

An article "Blast at BP Texas refinery in 2005 foreshadowed Gulf disaster" by Propublica mentions the following about the BP Texas city refinery incident:
Soon after the merger, BP demanded a 25 percent budget cut across all its U.S. operations.
Among the reductions at Texas City:
* Cut inspectors and maintenance workers by the dozens to save just over $1 Million.
* Eliminate safety calendars: $40,000 in savings.
* Reduce purchases of safety shoes for employees: $50,000 in savings.
* Eliminate safety awards: $75,000 in savings.
An outside auditor that Parus had hired, produced what was probably the most damning internal report [2] ever to emerge from the Texas City refinery. After surveying more than 1,000 workers and interviewing hundreds, the auditors concluded that the plant's employees had an "exceptional degree of fear" of a catastrophe, and that "blindness" across the entire corporation prevented critical safety information from reaching the top levels of BP management. It also said that poor conditions at the plant created hazards "you would never encounter at Shell, Chevron, Exxon, etc."
The 62-page report included direct quotes from some of the workers:
"The heroes around here are the ones working to the production goals and who complete them early. 80 to 90 per cent of what gets recognized is doing it fast counts."
"Telling the manager what they want to hear, that gets rewarded. For example, one person who had cut costs, done a lot of Band-Aids with maintenance and had a quit-your-bellyaching, quit-your-complaining attitude was rewarded in the last reorganization. When his replacement was brought into his previous maintenance position, his replacement found that not a single pump was fit for service; air compressors, not one spare was fit for service."
"Units are 90% of the time run to failure, due to postponing turnarounds [maintenance]. So making money or saving money for that particular year looks good on the books. This is a serious safety concern to operating personnel. We do not walk the talk all the time. Costs and budgets are preached to reduce costs."

Corncobs to Ammonia

I read an interesting article that would be of use to my friends in the Ammonia Industry. A company called Syngest is setting up a plant to convert corncobs to ammonia.
"The bio-ammonia plant will turn 150,000 tons of corncobs into 50,000 tons of anhydrous ammonia annually, enough to fertilize 500,000 acres of land. The process involves a pressurized oxygen-blown biomass gasifier operating in an expanding bed fluidized mode. After the resulting syngas is cleaned, the carbon monoxide portion is shifted to maximize hydrogen, which is purified and catalytically reacted with nitrogen to make ammonia. Syngest has procured 75 acres for the plant, five of which will be used for the facility itself and the rest for biomass storage. The plant will require 10 percent of available corncobs within a 30- to 40-mile radius".
I was wondering that even after so many years,the production of ammonia still needs high pressures and temperatures.When will we see an inherently safer process?

Process Safety and Bottom of the Pyramid!

I am borrowing a phrase from the late Dr Prahalad, Management Guru, when he was mentioning the fortune to be mined at the bottom of the pyramid.As far as process safety goes., misfortune lies at the bottom of the pyramid!
A news article mentions today that 9 IOC officials, including the GM of the oil depot have been arrested by the police for the Jaipur oil depot fire. The report quotes the incident investigation report by an independent panel which mentions that "human error, lack of safety procedures and design flaws were found to be the major reasons responsible for the fire.The basic or root cause is an absence of site-specific written operating procedures, absence of leak stopping devices from a remote location and insufficient understanding of hazards, risks and consequences,M.B. Lal, who chaired the independent inquiry committee, said. In a 2003 audit, the Oil Industries Safety Directorate found that the remote leak stopping device was not working at the Jaipur terminal. The inquiry found that despite the recommendation in 2003, the device was never operational in the last six years, he added".
Does it not speak of an organizational safety culture issue??

Cost cutting Vs Process Safety

An excellent article in the Wall Street Journal mentions the following in the aftermath of the BP oil spill:
'Early on June 5, 2008, a piece of steel tubing ruptured on BP PLC's vast Atlantis oil platform in the Gulf of Mexico. The tubing was attached to a defective pipeline pump that BP had put off repairing, in what an internal report later described as "the context of a tight cost budget."
The rupture caused a minor spill, just 193 barrels of oil, but BP investigators identified bigger concerns.
They found the deferred repair was a "critical factor" in the incident, but "leadership did not clearly question" the safety impact of the delay. The budget for Atlantis—one of BP's most sophisticated facilities— was "underestimated," resulting in "conflicting directions/demands."

Until the April 20 explosion of the Deepwater Horizon oil rig in the Gulf, Mr. Hayward repeatedly said he was slaying two dragons at once: safety lapses that led to major accidents, including a deadly 2005 Texas refinery explosion; and bloated costs that left BP lagging rivals Royal Dutch Shell PLC and Exxon Mobil Corp.
An internal BP presentation from December 2007, early in Mr. Hayward's tenure, noted that there had been 10 "high potential" incidents at BP facilities in the Gulf since the start of that year, including one December case in which a worker suffered an electric shock but survived. A common theme, the report found, was a failure to follow BP's own procedures and an unwillingness to stop work when something was wrong.
"As we enter the last two weeks of 2007, we are experiencing an unprecedented frequency of serious incidents in our operations," Richard Morrison, vice president for Gulf of Mexico production, wrote in an email to staff. "We are extremely fortunate that one or more of our co-workers has not been seriously injured or killed."

Celanese and Process Safety

I had the privilege working for 8 years in a methanol plant in Saudi Arabia, a joint venture with Celanese,USA, from 1990 to 1998.Their focus on process safety at that time itself was very good.A recent article mentions the following:
"In 2009, Celanese sponsored a process safety symposium in conjunction with the China Petroleum and Chemical Industry Association (CPCIA). The goal was to explain the philosophies of process safety, share how Celanese manages its safety programs, and raise awareness of how to avoid catastrophic injury or loss of facilities.
A key message of the event was that the industry, government and companies were all responsible for process safety and must work together to make process safety improvements. This symposium was such a success that Celanese is again cosponsoring a process safety symposium in September 2010".

A little hydrogen can do a lot of damage!

A news article reports that an explosion caused by hydrogen gas in a University of Missouri biochemistry research lab on Monday injured four people and destroyed the laboratory.
"The explosion blew out the windows of the third-floor lab and breached the wall between the lab and an adjacent office. When fire fighters arrived on the scene, they found a small fire covering an area of about 5 square feet, Davison says. One sprinkler head was activated, but investigators aren't sure whether it activated from the fire or from the blast of the explosion. The source of the hydrogen gas was a standard 55-inch-tall steel gas cylinder, which did not explode".

Gas blowing of pipelines - CSB's recommendations

In my earlier post, I was dead against the blowing of new pipelines with natural gas to clear debris as there is a potential for an explosion or fire to take place where the gas is vented. The CSB, after investigating the explosion in the Kleen energy power plant has made similar recommendations to OSHA and others. I am quoting from their report:
Promulgate regulations that address fuel gas safety for both construction and general industry. At a minimum:
a. Prohibit the release of flammable gas to the atmosphere for the purpose of cleaning fuel gas piping.
b. Prohibit flammable gas venting or purging indoors. Prohibit venting or purging outdoors where fuel gas may form a flammable atmosphere in the vicinity of workers and/or ignition sources.
c. Prohibit any work activity in areas where the concentration of flammable gas exceeds a fixed low percentage of the lower explosive limit (LEL) determined by appropriate combustible gas monitoring.
d. Require that companies develop flammable gas safety procedures and training that involves contractors, workers, and their representatives in decision-making.

Heed the warnings!

An article in CBS News website indicates that the BP Gulf of Mexico incident was not a one off incident. There was another incident in another BP oil rig in 2003 where a similar incident occurred but the gas did not ignite!
"Shortly after lunch on November 27, 2003, Oberon Houston was in his office beneath the helideck of BP’s Forties Alpha oil platform in the North Sea, off the coast of Scotland. One of a select group (1 percent of BP’s staff) of young engineers and managers targeted by the company for rapid advancement, Houston, 34, was working out maintenance plans for the coming week when he heard what he thought was a deafening explosion.Only it wasn’t an explosion. A gas line had ruptured-allowing thousands of pounds of pressurized gas to escape at supersonic velocity. That caused a thunderous sonic boom. Debris from the burst pipe and its cladding rained down, adding to the impression that “an artillery shell had just hit the platform.” The escaping gas quickly formed a huge and potentially lethal cloud around the rig. Now the threat of an actual explosion was very real. The smallest spark would detonate more than a ton of methane gas.
No one died or was even hurt that day on Forties Alpha, thanks in part to high winds that helped to disperse the gas after about 20 minutes of extreme danger to the platform and its crew of 180 people. But Houston, the number two in command aboard Forties Alpha, knew full well what could have happened. “Unlike a similar incident on the ill-fated Piper Alpha platform,” he observes, referring to an earlier accident in the North Sea, “the gas did not ignite, so what could have been a major disaster for myself and everyone else on board was averted by sheer luck.”
Though Forties Alpha could have produced a similar conflagration, it was nothing more than a near miss which was soon forgotten. BP admitted breaking health and safety laws by failing to guard against corrosion on the ruptured pipe that allowed the gas to escape. It was fined $290,000. The bigger loss came in early 2004. Houston resigned, and BP lost one of its best young engineers."

Bhopal Gas Disaster Verdict 7.6.10 - Will we ever learn?

The Bhopal Gas Disaster Court verdict on 7.6.10 highlights the following:
The following are major contributors to the disaster:
1. Gradual but sustained erosion of good maintenance practices.
2. Declining quality of technical training of plant personnel, especially its supervisory staff.
3. Depleting inventories of vital spares.
4. MIC is a highly dangerous and toxic poison, even then storage of huge quantity in large tanks was undesirable. The capacity and actual production in the Sevin Plant is not required such a huge quantity to be stored.
5. The VGS (vent gas scrubber)and refrigeration plant were not adequate to the need of hour and more so they were out of order at the relevant point of time.
6. The nitrogen pressure was not adequate for long before the incident, so it was not maintained and hardly cared about.
7. The Public Information System was failed, neither the State Govt. nor the UCC or UCIL took any steps to appraise the local public.
8. Other alarming systems were also failed.
Together these factors combined to cause the multiple failures that underlay the calamitous incident, causing a vast destruction of life.
In my various assignments of investigating incidents,some involving fatalities,one or more of the above similar causes keep repeating.Why do we NOT want to learn from mistakes? Its because of a human fallacy - the longer it gets, the more you forget about an incident!

Dangers of Toxic gas cylinders

A newspaper report today indicates that at least 35 people were taken ill when they inhaled chlorine. It appears that the chlorine leaked when someone tried to steal the brass valve! Read more of the article in this report.
In 2009, there was a leak of chlorine form corroded abandoned chlorine gas cylinders.A water purification machinery was abandoned and four chlorine cylinders containing 300 tonnes of chlorine were dumped outside. Over the years, they corroded and finally developed a leak which impacted the villages nearby. Read more of this incident in this link.
Take care of your gas cylinders whether they contain toxic gas or otherwise. They can be potential time bombs!

Could another Bhopal occur in India?

I wish I could confidently say NO to the question!Though the big players take precautions,it is the small and medium scale chemical industries that require a lot of improvement.There are approximately 1700 Maximum Accident Hazard (MAH) units in India and they are supposed to carry out mock drills twice a year. Mr Bhardwaj, Member, National Disaster Management Authority is quoted as follows in an article in the Economic Times:
Mr Bhardwaj of the Authority strongly believes that such major accident hazard (MAH) units must adhere to all norms including executing two mock drills in a year. In fact, during the last four years, only 130 mock exercises took place out of which 33 happened to be in chemical industries. “We are emphasising more on prevention of such incidents rather than reacting to those. Yet, we need to prepare for any eventuality. Our mock-drills are big learning lessons as they also involve district administration,” Mr Bhardwaj says.

Bhopal and BP - I don't know!

On Thursday, BP's CEO Tony Hayward testified before the US Congress on the spill incident. His answers to the questions put forward by the congressmen reminded me of the answers Union Carbide personnel gave the then Police Chief soon after the gas leak.The police chief had asked what was gas had leaked and what was the antidote. The answers he got was "I don't know". In Thursday's hearing, the CEO of BP also has replied in a similar tone(I am quoting from the article) "I wasn't involved in any of that decision-making," he said.Were bad decisions made about the cement?"I wasn't part of the decision-making process," he said. "I'm not a cement engineer, I'm afraid."
Also, "I am not a drilling engineer" and "I'm not an oceanographic scientist."
What about those reports that BP had been experiencing a variety of problems and delays at the well?"I had no prior knowledge."
At one point a frustrated Rep. Henry Waxman, D-Calif., the chairman of the House Energy and Commerce Committee, interrupted the CEO. "You're kicking the can down the road and acting as if you had nothing to do with this company and nothing to do with the decisions. I find that irresponsible."
Hayward quietly insisted: "I'm not stonewalling. I simply was not involved in the decision-making process."
Rep. Eliot Engel, D-N.Y., voiced the committee's frustrations as the afternoon wore on. "You're really insulting our intelligence," he said. "I am thoroughly disgusted."
Waxman told the BP executive that in his committee's review of 30,000 items, there was "not a single e-mail or document that you paid even the slightest attention to the dangers at this well."

An article mentions the following: BP PLC's 582-page regional spill plan for the Gulf, and its 52-page, site-specific plan for the Deepwater Horizon rig vastly understate the dangers posed by an uncontrolled leak and vastly overstate the company's preparedness to deal with one, according to an Associated Press analysis. The lengthy plans were approved by the federal government last year before BP drilled its ill-fated well.Among the glaring errors in the report: A professor is listed in BP's 2009 response plan for a Gulf of Mexico oil spill as a national wildlife expert. He died in 2005.
The plan lists cold-water marine mammals including walruses, sea otters, sea lions and seals as "sensitive biological resources." None of those animals live anywhere near the Gulf.Also, names and phone numbers of several Texas A&M University marine life specialists are wrong. So are the numbers for marine mammal stranding network offices in Louisiana and Florida, which are disconnected.

How ready are you in your emergency preparedness? In some of the plants that I visit,I have noticed the site managements lackadaisical attitude towards the emergency response plan. It would be a good practice if the CEO of the company just activates a drill of the emergency plan without informing anyone about it. The skeletons would then come tumbling out!

Whistleblower policy for PSM and other systems

Today,organisations get certified to the whole gamut of ISO certifications and the management is lulled into a sense of complacency. I have observed a marked decline in the quality of certification and surveillance audits by certification agencies in India. Except for a few, many of the certification agencies also provide consultancy and training services for helping the organization to obtain certification.Though many organisations have a whistleblower policy, I feel there must be a separate whistleblower policy for any system deviation. This way at least the top management will come to know of what is going wrong in their systems!

Operating Procedures – Can they prevent accidents?

An article on the legal implications of the recent Bhopal Gas verdict quotes from the operating manual of Union Carbide “UCIL’s “Operating Manual Part-I – Methyl Isocyanate Unit” (October 1978), which the prosecution produced as evidence before the trial court, warned as follows: “…[i]t must be foremost in everybody’s mind that there is a probability of injury or accident round the corner. But these can be avoided if all are safety conscious and follow safety procedures strictly. Safety is our prime need. All chemicals like MIC, phosgene, HCl, CO, chlorine, MMA, chloroform and caustic soda, etc., however hazardous they are, can be handled safely by knowing the correct procedure. There is a correct way of handling them and there is ‘No Short Cut’. Any carelessness in operation will endanger you, your colleagues and everybody around you” (page 122).”
Just by having written procedures does not mean they will be followed. It depends on top management commitment to make the procedures work. And this is no easy work – it requires monitoring by top management on a 24 X 7 basis. With top management being busy always, looking at strategy, cost reduction, expansions etc, I feel that the focus sometimes does get lost. Read the full article in this link.

Bhopal - Blame it on the system!

Yesterday in an NDTV program on the Bhopal disaster verdict, the one conclusion that came through is to blame it on the system! Who designs systems? Cannot the government strengthen the systems? It is a travesty of justice for the Bhopal Victims. In 2004, on the 20th anniversary of the Bhopal Disaster, I met (Late) Ms Carolyn Meritt, then Chairperson of the CSB, at IIT Kanpur. She asked me one question, which I could not answer. Why is the PSM system not mandatory in India where Bhopal occurred? I am still looking for answers. See this youtube video on the reaction of Sathinath Sarangi, a bhopal activist.

Crisis Management - don't look at it only when it hits you!

Organisations tend not to invest on Crisis Management as they think it will never happen to them! It is a human fallacy to believe that as nothing bad has happened, nothing ever will happen. I was recently a witness to a major crisis in a chemical manufacturing unit and they were not prepared for handling it.The top management representative at the site had to deal with everything himself. Unless planning for crisis is done and periodically tested, you will not be able to manage it. See this excellent youtube video about the responses of BP CEO Tony Hayward starting from the accident in the Gulf,onwards.

Parkinsons Law for Process Safety Management

I have formulated Parkinsons Law for Process Safety Management:
1.If there is an incident in one plant, rest assured that the same incident will reoccur after 5 years!
2. If there is an incident in a plant that belongs to a large group of plants, rest assured that it will not be shared with others in the group.
3. If there is pressure on profits, the first thing to get compromised will be process safety.
4. If the person at the top does not have a perception of process safety risks,process safety will get compromised, no matter whatever systems are implemented!
5. Process near misses will continue to be missed till a major incident occurs.
A OSHA representative has testified before the senate subcommittee on safety in energy industries. The following are quoted from his testimony:
"In the wake of the Texas City explosion, OSHA initiated a national emphasis program with the goal of inspecting the process safety management programs of almost all of the nation's oil refineries. "I am sorry to report that the results of this NEP are deeply troubling. Not only are we finding a significant lack of compliance during our inspections, but time and again, our inspectors are finding the same violations in multiple refineries, including those with common ownership, and sometimes even in different units in the same refinery. This is a clear indication that essential safety lessons are not being communicated within the industry and often not even within a single corporation or facility. The old adage that those who do not learn from the past are doomed to repeat it is as true in the refinery industry as it is elsewhere. So we are particularly disturbed to find even refineries that have already suffered serious incidents or received major OSHA citations making the same mistakes again.
"Consistently throughout the course of the Refinery NEP, we have found that more than 70 percent of the violations we are finding involve failures to comply with the same four essential requirements:
"Process Safety Information: Frequent process safety information violations include failure to document compliance with Recognized and Generally Accepted Good Engineering Practices, (or RAGAGEP, which consists primarily of industry technical guidance on safe engineering, operating or maintenance activities); failure to keep process safety information up to date; and failure to document the design of emergency pressure relief systems.
"Process Hazards Analysis: We are finding many failures to conduct complete process hazards analyses. Often, there are significant shortcomings in attention to human factors and facility siting, and in many cases employers have failed to address process hazard analysis findings and recommendations in a timely manner, or, even to address them at all.
"Operating Procedures: Operating procedures citations are for failure to establish and follow procedures for key operating phases, such as start-ups and emergency shutdowns, and for using inaccurate or out-of-date procedures.
"Mechanical Integrity: This is a particular concern given the aging of refineries in the United States. Violations found by OSHA typically include failure to perform inspections and tests, and failure to correct deficiencies in a timely manner. In the Delek Refinery case mentioned above, for example, OSHA discovered multiple substandard pipes being operated, and the naphtha pipe whose explosion killed two workers and hospitalized three others had already ruptured once within the past few years.
"I have been deeply frustrated by these results.Over a year ago, we sent a letter to every petroleum refinery manager in the country, informing them of these frequently cited hazards. Yet, a year later, our inspectors are still finding the same problems in too many facilities. Clearly, much more work must be done to ensure effective chemical process safety.

Excellent Hazards of hot work video from CSB

This is a must see for all those involved in hot work, including chemical, oil and gas and food processing industries. What surprises me is that the same mistakes are being repeated again and again. India, with its very young workforce needs to keep educating its workforce and this CSB video is excellent. I myself have witnessed three fatalities due to hot work incidents similar to those described over 25 years ag0.
See the video in this link. Kudos to the CSB!

Bhopal Gas Disaster - Precedence of Profits over People?

As expected the verdict on the Bhopal gas disaster in the Indian court has raised a hue and cry in the media. While definitely agreeing that the verdict is too little,too late, I think we are missing the bigger picture here. What has India done to prevent another Bhopal type of disaster? In the USA, OSHA CFR1910.119 Process Safety Management became mandatory in 1992 for facilities handling, storing and manufacturing highly hazardous chemicals above a certain threshold quantity. There is no such rule in India even today. Why? Even the enforcement of the other existing rules is weak due to rampant corruption. I quote from MJ Akbar's article in the Times of India:
"If there is any explanation for Delhi's fudge-and-fuss approach, it can only lie in the Indian elite's very real indifference to the poor. What, one wonders, would have been the reaction if Carbide had leaked its poison over Lutyens' Delhi rather than five kilometers from the old Bhopal city? Would Anderson have spent 25 years in Tihar rather than a villa in Hampton's?"

Decisions and Disasters -2

A friend of mine who is in top management in a large organization sent me this article about the BP oil spill, highlighting the following points:
"With the schedule slipping, Williams says a BP manager ordered a faster pace.Williams says going faster caused the bottom of the well to split open, swallowing tools and that drilling fluid called "mud."
We actually got stuck. And we got stuck so bad we had to send tools down into the drill pipe and sever the pipe,Williams explained.There's always pressure, but yes, the pressure was increased.He discovered chunks of rubber in the drilling fluid. He thought it was important enough to gather this double handful of chunks of rubber and bring them into the driller shack. I recall asking the supervisor if this was out of the ordinary. And he says, 'Oh, it's no big deal.' And I thought, 'How can it be not a big deal? There's chunks of our seal is now missing,'Williams told Pelley.
The BOP is operated from the surface by wires connected to two control pods; one is a back-up. Williams says one pod lost some of its function weeks before. "The communication seemed to break down as to who was ultimately in charge," Williams said. What strikes Bea is Williams' description of the blowout preventer. Williams says in a drilling accident four weeks before the explosion, the critical rubber gasket, called an "annular," was damaged and pieces of it started coming out of the well.
Investigators have also found the BOP had a hydraulic leak and a weak battery".

Process Safety and POP's

No, I am not talking about Persistent Organic Pollutants! I'm talking about Pressure On Profits. Time and again, we see accidents happening even in the World's biggest companies who have all systems in place including OHSAS 18001,ISO14001,PSM, behaviour based safety and other programs, conducted HAZOP and LOPA studies etc. A current example is the BP oil spill in the Gulf of Mexico.Why does this happen? While everyone agrees that ultimately it is the human being who is the weakest link in any system, how do we ensure that safety is always looked at all times including times of pressure on profits? On one side OSHA is increasing the monetary penalties for deficiencies. Whether this will spur organizations to invest in process safety – we will have to wait and see. Ultimately decisions linked to spending and investments have a cascading effect on the whole organisation and finally lead to an accident. I was talking to the Head of Safety of a large organisation who had done a HAZOP study for a new facility. He lamented the fact that even though he had presented to the board the fact that the new plant was commissioned with only 50% of the HAZOP study recommendations implemented, there was no reaction from the board! This could be due to two reasons – a lack of perception of process safety risk and the lack of competence required to understand it. It’s a chicken and egg situation. The Baker Panel report on the BP Texas refinery accident in 2005 had suggested that BP appoint a person with process safety knowledge on its board, but as far as I know, BP has not appointed anyone.

Process Safety - controlled by Leadership, HR and Finance!

Having investigated numerous process incidents over my 30 year career, I have come to some mundane conclusions which I am sure everybody knows...
1. No amount of management systems can prevent an incident unless the top management (leadership) send the correct signals!
2. Process safety is understood by the operations and maintenance departments but not understood by the Human Resources (HR) department!The HR department should play an important role in understanding competencies, skills and training required for Process Safety. But in many organisations, the HR department does not really understand the requirements of process safety. However, in one organization, I did see a very responsive HR department - its head was an ex-operations man!
3. Last, but not the least, Money makes the World go around! Without allocating adequate resources, audit findings, HAZOP reports recommendations, LOPA recommendations, incident investigation recommendations - all of them are meaningless and remain on paper till a catastrophic incident happens.
The BP oil spill has instilled great fear among Oil and Gas companies who fear that the regulations will be tightened very much and they need to spend a lot of resources.
Meanwhile, new management systems keep on coming, companies keep getting certified and accidents continue to occur......
Stay tuned!
PS: I am not a Pessimist!

Understand the hazards of chemicals!

Two students in the USA were reported to be in critical condition early Wednesday after being burned by a chemical explosion.Investigators with the Atlanta Fire Department confirm the students were mixing chemicals for "recreation" and not as part of a legitimate class project. They describe the explosion was an accident.In your lab, are your personnel aware of the hazards of all the chemicals they use? I heard of an incident where a lab technician in a plant (the Lab was located in the control room building) was taking a bottle of solvent and using the lift (elevator) when he accidentally dropped the bottle. The solvent went down the elevators floor and collected in the well. A spark ignited the solvent and the person had to be rescued from the elevator.

Transportation emergencies and GIS

I know in India, that the Andhra Pradesh Government is using the Geographical Information System (GIS) for disaster management. I read a paper on "Assessment on the Consequences of LPG Release Accident in the Road Transportation via GIS Approaches". The authors have suggested integrating the results from consequence analysis to GIS tools, to get an accurate picture for disaster management. The advantage of this method is that the point of accident can be moved to any location using the GIS and a new result will be displayed for the LPG accident at the new location.

Emergency Response in the BP oil rig fire - Shades of Piper Alpha?

A detailed article in the Wall Street Journal about the lack of command and control system after the BP oil rig fire eerily brings back memories of the lack of emergency response after Piper Alpha disaster in 1988. In the BP oil rig fire emergency response, the article mentions the following points:
"The chain of command broke down at times during the crisis, according to many crew members. They report that there was disarray on the bridge and pandemonium in the lifeboat area, where some people jumped overboard and others called for boats to be launched only partially filled.
The vessel's written safety procedures appear to have made it difficult to respond swiftly to a disaster that escalated at the speed of the events on April 20. For example, the guidelines require that a rig worker attempting to contain a gas emergency had to call two senior rig officials before deciding what to do. One of them was in the shower during the critical minutes, according to several crew members.
The written procedures required multiple people to jointly make decisions about how to respond to "dangerous" levels of gas—a term that wasn't precisely defined—and some members of the crew were unclear about who had authority to initiate an emergency shutdown of the well".

We seem to not learn from previous disasters like Piper Alpha where similar confusion existed after the fire!

Fire in Chemical Factory

This youtube video shows a fire in a chemical plant in Andhra Pradesh. The official says that the plant was not in operation since 2006 and did not have permission to operate. But when you see the fire it appears that large quantities of flammable chemicals were stored in vessels that were very close to each other. See the video in this link.
