Asset Integrity policy

Maintaining the integrity of assets is of prime importance to process safety. Many a time, management looses focus on this important aspect. I read the asset integrity policy of Petrofac which, in my opinion is an excellent policy. I especially liked the last statement about responsibility and implementation.

Crisis management

I read an interesting article in Forbes where an entire top two levels of the management team (50 persons) died in a plane crash. The article mentions how the new CEO addressed the issue and brought the company back into its tracks. Now this was not a chemical manufacturing company, but just imagine if the same thing had happened in a chemical manufacturing organization. Many companies do have strict travel rules for its top management to avoid this exact possibility, but in India, there is an inevitability about "fate" and often these rules are flouted.
Does your crisis management plan address these issues?

Process safety - Gasket failures

Gasket failures contribute to a large number of leaks and some of them could be catastrophic. With skill levels going down in India, sometimes a simple gasket that is improperly fixed could cause a big disaster. Are you training your technicians on the intricacies of selecting and fitting gaskets?  A good article by Garlock on the causes and cost of gasket failure highlight the various issues that are simple but are often forgotten.

Emergency situations and tiredness

An article in the Times Of India mentions that Air India cabin crew have started a campaign protesting the extra hours they were forced to work.The article mentions that the cabin crews alertness is most important in emergency situation and evacuations where time is of the essence. In a chemical plant, during emergencies, it is very similar to emergency situations in planes and the operating crew needs to be alert. When I was shift in charge and had operators continuing on overtime, (especially from evening to night shift), I have seen the errors committed by these operators during emergencies. It is a human need for rest and you cannot fight it. Look at your staffing requirements properly and ensure that competent people are available in adequate numbers.

CSB's Chairman's comment on refinery safety

In an article in the San Francisco Chronicle, the Chairman of the CSB has commented on the spate of refinery accidents and says "I recently read some comments in the media suggesting that "accidents will happen" and suggesting that one bad mishap every few years is acceptable. It is not. The oil refinery industry has the resources to do a lot more to enhance process safety and thereby protect workers, neighbors and the country's increasing energy needs".

Responsible Care - to make it work in India

The accident at the fireworks factory in Sivakasi highlights the need for enhancing safety in the chemicals and explosives industry. There are two aspects to safety - one is voluntary and the other is enforcement. I want to talk about the voluntary initiatives. Initiatives like Responsible Care (trademark of American Chemistry Council) etc  are adopted voluntarily by organisations. In India, the awarding of the Responsible Care logo is carried out by the Indian Chemical Council (an organisation of chemical manufacturing units). The proof of the pudding in awarding the logo lies in the company not experiencing any fatal accident after the award of the logo. If any fatal accident does occur in a company that has been awarded the logo, then the logo must be withdrawn by the awarding authority. Unless this happens, the public are not going to develop faith in the process.
In India, for Responsible Care, I suggest that companies must adopt one more code called " mentoring of small scale industry" around the location of the unit. This means that resources for improving the safety in nearby small scale industries must be voluntarily expended by the company. This will have a trickle down effect to improve safety in the whole chemical industry.

The importance of pre start up safety review

OSHA has cited a company in the US that produces of liquid natural gas through a cryogenic process." The incident occurred while employees were restarting the process. Cryogenic liquids were improperly routed through equipment not rated to withstand extreme cold temperatures, resulting in the explosion and fire.The willful violation is for failing to conduct an analysis of pre-startup safety conditions and systematically managing changes to process-related technology, equipment, procedures and facilities".

Metrics and process safety

There is a lot of work in progress regarding leading and lagging indicators for process safety performance. While I do not dismiss the importance of the metrics, the problem is that unless the metrics are understood by the board or whoever is interpreting risk through the usage of these metrics, it will just be another non financial number. A dollar metric will grab eyeballs rather than metrics that tell you about leading indicators for process safety. This is the nature of humans. This can be avoided only by having technically competent personnel on the board of chemical companies. I believe things will improve only after it becomes legally necessary to have technically competent persons on the board of chemical companies and make them responsible for process safety management. Otherwise we will only keep seeing newer and newer terminologies but accidents will continue to happen and I will never be out of a job as a Process Safety Consultant!!
I welcome your views.

Accidents in batch processes

The Safety, Health and Environment Association, Bharuch has posted several incidents on its website. One such incident mentions the following:
"Incident:
During nitration in reactor runaway reaction occurred and suddenly the pressure of reactor raised and explosion took place within few seconds in reactor. Manhole of reactor was opened due to high pressure. Nitric Acid, sulfuric Acid & Benzoic Acid were involved in reaction. In this incident the mixtures of acids were sprayed in process plant, company ground and nearby company. The roof sheets of plant were broken due to explosion. It was sprayed up to about 200 – 300 meters in down wind direction
Cause of Accident:
As per information received from company officials the explosion occurred due to runaway reaction during nitration from reactor of process plant.
Corrective Action
Lime was sprayed on the acidic mixture in whole the affected area in company & on the road also for neutralization. After that the road was washed out with water. Company people also sprayed lime on the acid mixture in their company ground & Process Plant.
Preventive Action
1. Process parameters to be followed strictly.
2. PRV & safety valve to be maintained in working condition with proper venting system.
3. Periodical maintenance & inspection should be done.
4. Employees should be trained in process safety.
5. Laboratory Study for knowledge relative to normal & abnormal known deviation in raw material, Process parameter"
