When you enter analyser houses in chemical plants, ensure that the gas alarms are working and that there is no alarm before entering the confined space. As there will be tubing and other places from where gas from cylinders outside can leak, be careful.

How secure are your redundant systems?

An article in the Guardian highlights the importance of functional testing of your redundant systems. In the incidents mentioned, two helicopters of identical make faced a main lubrication oil system failure while airborne. Though the back up system came on line, an alarm indicated that it was not working properly, so the crew had to make emergency landings in the sea. Later it was found out that the back up system was indeed working fine, but the alarm was wrongly configured.

Proposed changes after oil rig accident


The Coast Guard issued a Federal Register Notice of recommended interim voluntary guidelines concerning mobile offshore drilling units, or MODUs, and manned fixed and floating offshore facilities engaged in activities on the U.S. Outer Continental Shelf. This is part of the Coast Guard’s continuing response to the explosion, fire and sinking of the MODU DEEPWATER HORIZON in the Gulf of Mexico on April 20, 2010.

The Report highlighted the following considerations as areas not specifically addressed by current regulations:
Minimum values are needed for explosion design loads for use in calculating the required blast resistance of structures;
Explosion risk analysis of the design and layout of each facility should be performed to identify high risk situations;
H-60 rated fire boundaries between the drilling area and adjacent accommodation spaces and spaces housing vital safety equipment may be necessary dependent on the arrangement of the facility;
Uniform guidelines for performing engineering evaluations to ensure adequate protection of bulkheads and decks separating hazardous areas from adjacent structures and escape routes for likely drill floor fire scenarios are necessary;
Performance-based fire risk analysis should be used to supplement the prescriptive requirements in the MODU Code; such analysis should use defined heat flux loads to calculate necessary levels of protection for structures, equipment, and vital systems that could be affected by fires on the drill floor;
Maximum allowable radiant heat exposure limits for personnel at the muster stations and lifesaving appliance launching stations in anticipated evacuation scenarios should be implemented.

Explosion in 3 D printing firm

New technologies but old hazards - A 3-D printing company, was cited by OSHA after an explosion and fire , which inflicted third-degree burns to an employee. The company was using combustible metal powders like titanium and aluminium alloys in the 3D printing process. There were no Class D metal fire extinguishers on-site during the explosion and fire.

"Establishments that use metal powders in this new technology need to scrutinize their processes and take steps to prevent and protect their employees from fire and explosion hazards that arise with these materials," said Robert Hooper, OSHA's acting regional administrator.

Reactive chemical incident due to human error

In 2012, a tragic accident in a pharma plant in Ireland claimed the lives of two employees. Apparently, the cause was due to human error in a batch reactor, when the reactants were charged without charging solvent first. The rapid reaction took place without the solvent in place to absorb the heat. This caused the reactor to explode. A news article mentions that one of the ambulances that took one victim was later found so contaminated with chemicals that it was decommissioned.
When you know that certain reactions can dangerously overheat if the operator forgets a step, proper engineering controls should be implemented.

Simultaneous jobs and their dangers

Many times, during an annual shutdown of a chemical plant, many jobs will be taking place and there is pressure to complete the  jobs on time. Be careful during this period as there may be a tendency to overlook some of the hazards due to simultaneous jobs. Your regular HIRA (hazard identification and risk assessment) may not be adequate and some risks due to nearby jobs may be skipped. Before every turnaround ensure that a special training is given to the people who conduct HIRA on how to identify hazards from simultaneous jobs.

Are you travelling in a confined space?

In a lighter vein........
I am sure many of you will be flying frequently on official visits. Though planes are designed to be evacuated very quickly during an emergency, I often compare them to flying in a confined space! I have tried to correlate the system in chemical industries used for confined space entry to that of flying in a plane:

Confined space entry permit = boarding pass
Man watch = flight stewards
24 V lighting = emergency escape path lighting
Air blower system for ventilation = cabin air pressurisation system
Oxygen monitoring = oxygen masks drop down when oxygen is less
Rescue plan = emergency exits and chutes
Chief emergency and rescue controller= pilot!


I am sure you will be more comfortable when u fly next!! All the best!

The GM recall - what are the lessons in process safety culture?

You must be reading the news about the recall of 2.6 million cars GM made due to a problem in the ignition switch which could shut off the car while driving, disable the airbag, power steering and anti lock brakes. However it is reported that GM took 10 years from the time the problem was discovered and recalling the cars to fix the problem. Meanwhile 13 deaths have been attributed to this.
 In the ongoing Senate hearing, the recently appointed CEO of GM Ms Barra told the subcommittee, "that the new GM is more "focused on the customer" compared to a "cost culture" years ago at the automaker."

What is the commonality between a giant automotive maker and PSM? The answer is "cost culture". Beware of the cost virus in your organisation's PSM system.It can cause deadly accidents.

When the back up fails........

 When I was working in Saudi Arabia, the 3000MTD gas based methanol plant was operated with state of the art DCS systems. Just before a planned turnaround, instrument personnel were working with some control room underfloor cables when, by mistake, all power to the DCS displays were lost. It was restored after 30 minutes. The plant parameters were maintained throughout the upset without any safety issue as the controllers in auto were doing their job. However a case study presented in 2012 by Shri KC Tripathy and others of NTPC shows how safety hazards cropped up during "complete and simultaneous DCS failure in two 500MW units"
The case study mentions among other useful learnings, the following:
"All processors (active and redundant) abruptly rebooted at once. Thereby both redundant network & redundant processor concepts of DCS design were defeated".

Lessons from NASA astronaut "water in helmet" incident

In July 2013, during a spacewalk outside the International space station, an astronaut reported water entry into his helmet. He was asked to get back only after he made three calls saying the water didn’t appear to be from a drinking bag. Later it was found out that the drinking bag was not the problem and a choked filter was the cause of the leak. The NASA investigation report mentions some of the reasons for the incident as inadequate training, the crew members and ground misunderstanding the severity of the situation, and a (false) perception that any water leak is likely due to a problem with the drinking bag. Do not normalize deviations!

Interesting incident from workshop

Am currently attending an Indo US workshop on Science and technology for preventing terrorism. A speaker from the US mentioned an incident involving human factors - a highly secure facility which had three layers of security was penetrated by a group of activists, who managed to penetrate all three layers without being noticed by guards. When the activists reached the  secure building, they tried throwing some stones to attract attention, but the security guards thought that carpenters were working late and ignored the noises. Finally they were detected and apprehended. The incident was captured by video. The speaker highlighted that the guards never anticipated a breach as they thought that the three layer security was foolproof. The guards let their guard down! When people do routine monotonous jobs, there is a tendency to ignore warning signs as they are not alert enough.
The same applies to operators who run complex chemical plants with layers of automation. It is a human tendency to think that automation will always do its job. Make sure your operators are trained in the hazards of over dependence of automation. (automation addiction).

Most probable cause of the accident was oxygen depletion due to rusting inside the decommissioned sub. Many times, we feel that a decommissioned equipment is safer than an equipment that is in service. We let our guard down and then a fatality occurs. Sometimes, new equipment are brought to the site before a turnaround and placed near the unit. They may be nitrogen blanketed and have to be treated just like any vessel in service.

Process safety - where are we heading??

I was reading an article on process safety and a new terminology called "peak risk". In the last decade a number of new terminologies and technologies have mushroomed. But I think we have lost our way somewhere. Ultimately, accidents happen due to decisions taken by Management that have an effect on process safety and causes a catastrophic accident. Over a period of years, chemical manufacturing companies have fewer and fewer technical personnel on the board. As long as we do not address this issue, new terminologies and new technologies will only make someone's purse fatter but will not prevent a catastrophic accident!

Laws of process safety

 And now for a bit of humour, I have coined some laws of process safety.....
  • Process safety performance is inversely proportional to the time a plant / maintenance manager spends in meetings!
  • The number of technical persons on the board of a chemical manufacturer is inversely proportional to the chance of a process safety incident occurring
  • The more voluminous your PSM program, the more likely a process safety incident would occur.
  • Managing process safety is no rocket science - it is look,listen and feel (look at what people are doing, listen to people and feel the pulse of the plant)
  • Runaway reactions always happen when the human is around!
  • Process safety management does not require six sigma, it requires stick sigma!

Salt water tank explosion

In some places, oil and gas reservoirs are found in porous rock formations that also usually contain significant amounts of saltwater. The saltwater produced with oil and gas must be disposed of in a manner that will not cause or allow the potential for pollution of surface or subsurface waters.. In this incident, a salt water tank exploded and 13 other tanks caught fire. The explosion, which occurred after a truck driver had unloaded the salt water into the tank and was leaving the site. The only victim was the truck driver who offered to help firefighters by getting more water to extinguish the fire. While the truck driver was heading back, he suffered a suspected heart attack.The cause of the explosion is under investigation. But this incident highlights the need to treat all tanks with respect.

Changes proposed to OSHA PSM rule

"On Dec 3, 2013 The U.S. Department of Labor's Occupational Safety and Health Administration announced a request for information seeking public comment on potential revisions to its Process Safety Management standard and related standards, as well as other policy options to prevent major chemical incidents. The RFI is in response to executive order 13650, which seeks to improve chemical facility safety and security, issued in the wake of the April 2013 West, Texas, tragedy that killed 15 in an ammonium nitrate explosion. Once the RFI is published in the Federal Register, interested parties may submit comments online atwww.regulations.gov, by mail or facsimile. To view the RFI visithttp://www.osha.gov/chemicalexecutiveorder/OSHA_PSM_RFI.pdf. For more information, visitwww.osha.gov/chemicalexecutiveorder/index.html."

Technology and emergency response

Thermal imaging technology has been around for decades and it's cost has come down, together with improvements in technology. Often they are used to detect hot spots in electrical systems and insulation or refractory hot spots. Now firefighters are using this technology in emergency response rescue.

Explosion of acid tank in Fertilizer Plant

 An empty acid tank exploded during maintenance. This occurred in a phosphate fertiliser manufacturing facility in the USA. The lid of the tank apparently flew 100 feet in the air. Two people were injured.There is a lesson from this and other similar incidents - tanks are dangerous, be it empty or full. Follow all proper hot work precautions. Even waste water tanks have exploded during hot work due to the release of gases.

Lightning causes tank to explode

A salt water tank containing trace amounts of hydrocarbon exploded in the USA after a lightning strike. The explosion of the tank caused other nearby tanks also to catch fire. This incident highlights the importance of maintaining the integrity of your lightning protection system. Many plant managers do not pay heed to this protection system, thinking it will never happen.

Excellent article!

Chevron Fire One Year Later - What Will It Take to Prevent Another? - New America Media

"There needs to be a fundamental shift of the burden of proof that a company is operating safely. Right now, the burden of proof lies with public agencies; they’re charged with playing Sherlock Holmes and trying to find hazardous conditions. What’s needed is to shift the burden of responsibility for safe operation to the plant. They have to demonstrate their competence in health, safety, and environmental performance as a condition of operation. Then a public agency can determine whether the plant is meeting those standards, and whether they’re sufficiently competent or not. That would change things. And, if the whole process is much more transparent and accessible to the public, that would make health, safety, and environmental performance much more compelling to the plant management".

Trevor Kletz passes away

The father of process safety has passed away at the age of 91. Dr Trevor Kletz had authored many books on process safety and also introduced the concept of inherent safety much before the Bhopal disaster. My early working days were spent devouring his well written books and his subtle sense of humour. I  pray his soul rest in peace!

Another view of behaviour based safety programs

I have always maintained the view that behaviour based safety programs will succeed only if top managements behaviour is also observed and corrected. Read an interesting article from a unions perspective in this link. This article should be read by all top management.

HPCL Fire investigation

 According to a Times of India report, the Oil Industry safety directorate has faulted HPCL management for the August 23rd inferno in the cooling tower which claimed 28 lives.The article mentions the following:
"Revealing the lack of precautions taken by HPCL-Visakha Refinery, OISD said that internal pre-commissioning safety audit was done by a multi-disciplinary team of HPCL but the "recommendations/ pending jobs were not completed".
The lapses list
** Management failed to stop commissioning even though several processes remained unfinished
** Nearly 100 personnel were allowed to be present and work at the site during commissioning
** No senior official was available at the site and commissioning activity was left to one supervisor only
** Hazard identification not done and no risk analysis carried out
** Hot job carried out under the supervision of the maintenance department
** Contract workers not told to leave the site before the commissioning of the facilit

COMMENTS ON CHEMICAL PLANT SAFETY & SECURITY RATING SYSTEM


I appreciate the initiative on the new safety and security rating system for chemical plants by the Indian Government and am sharing my comments sent to the Ministry on the new safety rating system:
1.    The initial screening criteria will eliminate many of the existing chemical units in the small and medium scale sector which also handle highly hazardous chemicals.  In such a case, what will be the action? I suggest that Initially, for SME sector, certification to OHSAS 18001 could be made mandatory and the proposed safety and security rating system be applied to MAH units. Later the modalities to extend it to SME sector could be worked out.
2.      In the initial screening criteria, one of the KPI’s is mentioned as “approved and documented PSM system available and implemented”. There is no reference to which PSM model to follow. I suggest that the basic OSHA CFR 1910.119 PSM rule of USA be followed. The threshold limit of chemicals for which PSM system applies could be the same list used in MSIHC rules.
3.    Any rating system is a snapshot of the organisations safety performance. However, in process safety management, top management commitment and technical competency of the people who run the system are important for achieving incident free performance. The proposal for the new safety rating system suggests that organisations with good safety performance will be incentivized. The opposite of this must also be implemented – if an organization that has been rated either 3,4 or 5 star in the new rating system experiences a reportable accident ( as defined in factory rules) after the award of the rating and within the periodicity of assessment, then the rating should automatically be downgraded to “Poor”.  This will ensure continued top management focus. The list of organizations who have been thus downgraded may be publicized on the Ministry of Chemicals and Fertilizers website or on a new website specifically dedicated to the “Chemical Plant Safety and Security Rating system”
4.      In the 19 KPI’s of final assessment, KPI’s 12,13 and 14 (Contractor management, emergency preparedness and response and training and competency) are already covered in the PSM system mentioned in KPI 2. They can be assessed as part of the PSM system.
5.      As the concept of “Occupier” and “Factory Manager” is already legally required for companies, I suggest that both of them be mandatorily assessed in final assessment on how they track PSM performance as well as competency levels to maintain the PSM system.
6.      In the evaluation questionnaire for PSM, in point 2.3, it is asked if QRA/LOPA is done for all operations and recommendations implemented? Instead, the question could be Whether Hazard Identification and risk analysis based on guidelines of IS 15526:2006 has been carried out and recommendations implemented?
7.      Finally, the new rating system will be recognized as unbiased and transparent by the public only if the if the assessment evidences for those organisations that have been awarded “Good, Very Good and Excellent” are posted on the website of the Ministry of Chemicals and Fertilizers or on a new website specifically dedicated to the “Chemical Plant Safety and Security Rating system”
