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.

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".

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”

Simple properties of chemicals and process safety

The newspapers are full of reports of a dry ice explosion in a restroom in LA international airport. Dry ice or solid CO2 has a property of directly changing into gas from its solid state as it's temperature increases. If the dry ice is kept in an enclosed container, then it exerts immense pressure and can explode the container. The discovery channel has a video in this link which demonstrates vividly what can happen. Worth a see by all plant operators to realise the hazards of chemicals.

"This is your pilot sleeping"

A recent incident in a British airline where both the pilot and copilot dosed off because of lack of adequate sleep in the previous nights highlights the importance of fatigue management in the chemical industry, too. While the chance of a control room operator in a common control room in a chemical unit to fall asleep unnoticed is less, fatigue often impairs judgement and reaction. For plants using process simulators for training, it is worth to take the trainee through a series of night shift training sessions so that he himself feels the difference.

Possible dust explosion during hot work

Thanks to Sujith for sending information on a possible dust explosion in a tank storing HDPE in Korea, during welding work. The news article in the Korea Joongang Daily mentions:
"The sudden and massive blast hit the plant, located at the Yeosu Industrial Complex, at around 9 p.m. Thursday, catching workers engaged in welding off guard, some falling 30 meters (98.4 feet) down from the tank to the ground, according to witness accounts.
The death toll is likely to rise as five of the 11 wounded are reportedly severely burned. Firefighters contained the fire within 10 minutes after the blast.
The plant, owned by Daelim Industrial, was undergoing maintenance work at the time.
Workers were welding a door into the tank to make an entrance so the company could send inspectors in to examine the interior, the company said. 

“We checked if there was remaining gas in the tank every time workers were put to work, thus multiple times a day,” said an official with Daelim’s public relations team, who requested anonymity.
“Each time, the result was zero. There was no gas lingering in the tank and thus that was not what caused the explosion.”

Inherent safety and LOPA

A Chemical Engineering friend of mine (Vijay) who has about 35 years of experience in Process Industry wrote in to say this:

"Participated in a LOPA study involving pyrophoric materials. However, what struck me was people failed to understand intrinsic safe and unsafe. They did not grasp that giving high SIL rank and spending lot more on SIL certified instrumentation does not buy any increased safety from accidents that can occur when a pyrophoric material is handled. Only a process change can make things safer, not SIL certification or LOPA for inherently unsafe processes. This also happens to be the message of Fukushima. But people dont get it".

Gas leak into cooling towers

In an article in the Hindu dated  August 27,2013, it quotes a top official of HPCL saying  "in fact such an accident is first of its kind in the world history. A blast of this kind in the cooling tower in unheard of”.

For those in the process industry, gas leaks into cooling towers are not a one off affair. Heat exchanger tube leaks can cause a surge of gas into cooling towers. I had experienced one such incident  30 years ago. Dr Trevor Kletz, in his book " What Went Wrong" mentions under the category "Heat Exchangers", in page 105, the following incident "A leak in another heat exchanger allowed flammable gas to enter a cooling water return line. Welding, which was being carried out on the cooling tower ignited the gas. The atmosphere in the cooling tower had been tested before work started, 5 hours earlier"

Cooling towers are often falsely thought to be harmless, but they can become killing towers in no time.

The article mentions that out of 22000 chemical units in USA just 100 are members of ACC which requires data on accidents to be made public. The article ends in this note:
“Why would a company or organization do data checking? They might do it because there is a liability risk. They might do it because they feel it’s the right thing to do,” Podgurski said in an interview. “But even in an honest organization, deadline financial pressures will mitigate those efforts.”

Hot work or Cold work?

An incident where a person passed away in a tank explosion revealed that the work permit that was used in the facility was a single permit for both hot work as well as cold work. The issuer had to tick mark whether it was a hot work or cold work to be done and take the appropriate precautions. The permit was issued without marking whether it was hot work or cold work to be carried out. Lack of this clarity led to a hammering operation with a ordinary hammer taking place at the top of the tank which had flammable material inside. The spark produced during hammering fell into the tank through an opening and the tank exploded.

While the reasons for the incident are being investigated, please remember that Flare systems are emergency safety systems and that we need to pay them great attention. Often fires get reported due to water seals blowing, overflows from flare stacks, and inadequate maintenance. Are you giving your flare systems the same importance as a single stream rotating equipment?
