Toxic gas leak from neighbor factory affects 60 in a garment factory

Some workers of a garment factory sensing strong smell of a gas tried to runaway from workplace but fainted before reaching the gate. A taxi driver outside, seeing them call the help services. Security guards from neighboring factory said that there was a gas leak. About 60 persons were affected in this incident.

From the above, it is important to all persons working in a cluster of factories to know about hazards and emergency actions not only from their work place but from surrounding factories also.

Ammonia leak from food freezing system from the neighboring factory is suspected in this incident.

Unruly behavior of employees with safety officers

 I heard many times from my friends in safety department in various government and private organizations about the tough talk and occasional insulting behavior by those in the production line when discussions take place on safety issues. The hazards identified are ignored with a sarcastic remark that safety officers do not have any other job other than pointing out and the hazards pointed out are often not considered fit for action. They do not try to learn from incidents happened elsewhere saying that it is too theoretical and will not happen in their plant because of their confidence on their management skills.
We have ignore the unruly behavior of others as it is not in our control and we should not get disappointed and stop doing our job. We have to collect case studies of other organizations that resemble situations in our work place and keep circulating to all employees including top management for information.
We have to be bold and if required we have to take up to the notice of higher authorities when junior level people do not listen. Most of the time, people will sit straight when issues are put in writing with a copy marked to group heads and CEO or MD. I am sure this will help over a period of time in controlling unruly managers.

Home poisons - tips to handle the dangers

There is an article in The Phillippine Star about 10 most common poisons at home that are likely to harm children health and one of the poison in the list is paracetamol, though I do not know how it can cause harm. An article in internet is given here about paracetamol use and hazards. The other items in the list include kerosene, caustic, paint thinner, pesticides and button cell batteries. Tips given for preventing poisoning include reading product labels about hazards, usage and disposal, personal hygiene, proper storage, etc.

How to Use Safety’s Magic Metre

Here is an article on protecting oneself from hazards including workplace violence. Though, all of us know to maintain distance away from hazards, rogues, etc, it is presented in a knovel way by the author.
How to Use Safety’s Magic Metre

Bhopal Accident - One more year passed!

Another year passed to count on Bhopal accident. After the Bhopal accident, we can recount the accidents at HPCL, Vizag and IOCL, Jaipur where human lives are lost in double digit. We do not know, how many are going to happen at any time. We may think that we are doing pretty well on safety matters, but it is the luck and time factor rather than our safety alertness that accidents of great magnitude did not happen.

All of us know what to do to avert an accident, but complacency and wrong priorities make us to delay immediate actions for improving safety at workplace.

In the West, well established industrial organizations saw occurrence of accidents, though there safety record is at its best till the occurrence of the accident.

Though, incentives do not lead to permanent safety solutions, still we can offer significant incentives to employees who point out hazards and those responsible for allowing those hazards should be punished parallelly.

Too much freedom and associated inaction should not be tolerated in any hazard installation and wrong doers should be handled severely.

Use of robots in automated processes - What are the safety implications?

Automation of processes is preferred by most of the organizations as it reduces human interface and improves productivity. In manufacturing / engineering industry, auto sector, etc most of the material handling jobs are automated and robots are engaged for complex jobs. This reduces lifting of weights of human beings, avoids stress / strain caused due to repetitive jobs and thus reduces health care costs.

However, it is important to understand the programming that went into sequencing of operations to be done in automated jobs and its implications particularly when the jobs are partly automated, partly manual. The job may look simple when routine sequence of operations are carried out. However, if any interruptions / change of sequence is there or breakdown occurs or power failure takes place, we need to know its impact on operations. May be we did not thought of restricting the functioning of robots or like it happens in computers when power failure occurs, there may be hanging of the computer programme. Whether such a situation creates any hazard to shopfloor operators in the vicinity is to be assessed.

Or, what are the hazards when maintenance is to be done when these automated systems are in energized condition. Whether safe positioning is incorporated when emergency stop switch is operated is to be known. Else, when someone looks into the problem during a breakdown, any of his repair job may cause the robot arm to move and hit the maintenance engineer.

Before programming the logics, a detailed WHAT IF analysis is to be done by involving concerned including design engineer, operation engineer, instrument engineer, maintenance engineer, safety engineer, etc to assess all possible hazards for all regular operations / breakdown jobs / maintenance, etc.

Still, there may be surprises depending upon the extent of questioning, imagination, thinking is put during hazard evaluation.

Sparks fall on solvents causing burns to two persons

A newspaper report stated that in a pharma company, sparks fell from a capacitor when two electricians were on the job. The sparks fell on the nearby solvents and chemicals, leading to fire and burn injuries on face and arms of the two electricians.
Safety norms say that ignition sources should not be present atleast 15 m around the flammable storages. Though this is applicable for hot works, the same logic can be extended for storage of flammables also. It is likely that sparks can fly along the wind and can cause fire. The solvent storage area also should be provided with dyke so that leakage / spillage will not spread and are contained.
If it is not possible to remove the flammables away from ignition sources, atleast they should be covered with asbestos cloth or similar fire resistant cover; sand and other suitable fire extiniguishers should be provided near these flammable storages; fire department of the plant should be informed about the srorage and maintenance jobs proposed to be takenup; carryout hazard analysis; communicate the workers about hazards and safety measures to be taken; etc

An animated video describing the hazards during hot works in flammable areas is available at US Chemical Safety Board website (http://www.csb.gov/) and the video link is given here.

Hazard Communication - One more idea to warn to about dangers

In my earlier post, I mentioned few things to communicate hazards to machine / equipment operators. In addition, it will also be effective to caution about hazards, if photos of persons injured are displayed on every equipment / machine. I feel such reminder will have the desired effect on the minds of operators and shopfloor supervisors so that they will not bypass safety procedures. It is like having photos of our loved ones in the house to remember about their affection. In the shopfloor, it is like remembering the mistakes made by the persons in the photos and the injuries suffered by them.

Hazard communication - Way to reduce accidents

Accidents recur regularly on same or similar process / machine. A friend of mine said once that operators and supervisors can be reminded about the hazards by displaying on every equipment/machine, the list of persons injured - causes for accidents - protective measures taken subsequently so that people will not forget, do not opt for shortcut methods, do not bypass safety systems.

Further, flowsheet / block diagram, hazards, safe operating procedures (SOPs), dos' and don't's, safety systems and controlling parameters, location of emergency switches, checklist to be used before start of every shift, etc can be displayed on the particular equipment in the languages understood by the concerned persons to ensure safety at the workplace. I am sure, this will definitely help in reducing the accidents, though the information sheets displayed are more. One has to spend time in preparation of these information sheets once and they need to be changed only when they are required and approved by higher authorities.

Concerned operators and supervisors should be involved in preparing these information sheets so that they are relevant and are understood. Further, they feel that they are part of the system and are therefore responsible for ensuring safety.

Who is responsible for safety?

After the last week verdict on Bhopal tragedy for fixing the responsibility, so many people in responsible positions commented about the verdict. The Factories Act 1948 amended after this 1984 accident fixes the responsibility for ensuring safety at the work place on the occupier as well as the manager. It also says (Sec 101) that if the occupier is able to prove that he has given full responsiblity and resources to others down below and that the accident occurred because of deeds of his subordinates without his knowledge, then the said person can be held responsible.

Someone commented that a car owner can't be held responsible, if his driver makes an accident. It is forgotten that the driver was put into job by the owner of the car and nobody else (unless car was stolen and is not reported in the police station).

If managements employ less qualified or unsuitable persons for the job, then there is every possibility that accidents / incidents can take place. In risk assessment, human error is also a factor. In fact, experts say that systems should be designed and put in place such that even a fool can not meddle and lead to accidents.

In the case of Bhopal accident, it is mentioned that the some of the workers, superviors and managers were brought from Battery Division and do not have proper training / exposure to run the plant. Even the audit report of Union Carbide warned about imminent dangers, a few years before the accident. Few accidents occurred earlier also support that a major accident will not occur all of a sudden, but will be preceded by few near misses and minor accidents.

As the plant was not in operation for few months before the accident, poorly trained managers and supervisors decided to switch off the refrigeration system thinking that when plant is not running, nothing will happen (because of lack of knowledge on hazards). Persons were not informed about the hazards, neither they had interest to learn on their own, about what can happen in their day-to-day activities. All of us will be careful to caution our children about their safety when they go to school or college. But we do not follow the same at our work place.

Apart from deactivating refrigeration system, the srubbing unit and flare tower were not kept in working condition. To prove Murphy law, every safety system went wrong simulataneously (neither functional nor available at the time of accident). The water sprinkler, a last resort, had limitations of spraying water upto a height of only 15 m where as the gas eascaped from the flare tower at a height more than this.

There are provisions and punishments for causing deaths due to negligence, callous attitude and accused should be awarded compunded punishments. If the wrong doers are not punished severely, this will send a wrong message to all greedy corporates that nothing will happen to them and they can find some scapegoats at lower levels for the minor punishments.  In the famous novel God Father by Mario Puzo, it is mentioned that underworld people keep some persons with opposing gangs as a surity for the persons from these gangs attending meetings so that they can participate the meetings and leave the place safely. Scapegoats will be found like in the underworld system.

The entire property of the owners of the factory causing such large scale deaths should be confiscated and it is better for governments to work toward making international laws to confiscate properties of the owners in other countries also.

Safety Practioner: A Pessimist? or A Visionary!!

A safety officer’s main role in the organization to help in hazard identification and thus he will have a hawk’s eye for hazards. The conditions which are normal for the plant personnel will be hazards in the eyes of safety man and thus when he tells shop floor persons about hazard and need for elimination, the safety man will be seen as a negative minded person. He may be scolded, chided and will be at receiving end depending upon the safety culture of the organization. If the safety officer is having thick skin, then he will not bother and will continue his work. If not, after sometime he may stop cautioning about hazards. If some unusual incident occurs, then again same safety person will be blamed for not identifying the hazard and intimating the concerned. He will be come pessimistic and all his goals / objective in the beginning of a career in safety will lead to total frustration and he will be at cross roads to do what. He will be stressful and it is not possible for any person to be optimistic for ever. Though pessimistic attitude is good for a safety man in hazard identification, when this reach his mind and carried to home, it may spoil his home life also. Over a period of time, he will be at peace neither at work place nor at home and will be blamed all around.

Therefore, it is important for safety professional to stay positive and exercise like walking will help him to stay fit, physically and mentally. Listening to music, attending cultural programmes and book reading are some of the activities which can help the person to lead a peaceful life. Similarly, visiting new places, monumental or religious or others, will fresh up the life.

If it is not possible to continue in the safety department, he can think of change of job. However, I know some persons who left their organizations in frustration continue to be frustrated and are frequent job changers.

There are many programmes available to take care of different professionals, but professionals who help the organizations to identify hazards are helped in identifying their hazards. These safety professionals have to take care of themselves and safe guard their health and life beyond office.

Once the person overcomes his stressful life because of his profession, still keeping his pessimistic approach, he can be helpful to the organization in hazard identification. A safety officer in an organization will have the moral responsibility of ensuring a safe work place and also see that management will not take wrong decisions because of his work methods. He has to envisage what can go wrong and provide feed back to the management in the form of reports regularly. He has to convey hazards along with the statutory requirments under which these are seen as violations and for thick skinned persons, safety officer should not hesitate in telling about the penalties / punishments one deserves for the violations. Though, punishments or penalties are seen as last resort and people say they are not helpful in straightening the organization, as we see the occurrence of incidents in well advanced countries and the penalties imposed by the regulators in these countries, there is no other solution.

In fact, organizations should develop their own penalty structure in terms of cash fine or reduced pay or suspension of the employee from work and termination as last resort. Then, everybody will have the fear of following safety priniciples which the management wants to follow. Of course, nothing can be done, if the management it self pays only lip service to safety.

Why Gas cylinders should be kept in sun shade?

I read in Rules for gas cylinders that gas cylinders should be kept under sun shade, should not be exposed to direct sun light, the storage area should have good ventilation, etc. Though the reasons are known, i.e to avoid over pressurization due to the exposure to sun, I saw practically how over pressurization takes place in the cylinder when exposed to sun light directly.

Recently, I was on a visit to one of our sites under construction. After my visit to the construction site, at about 1230 hrs in the noon, I was going back to the office where I normally sit. I don't have permanent table and chair as I visit the site occasionally and there are permanent safety officers already appointed at site. On the way, I saw some argon cylinders stored on the road side under direct sun light, without valve caps. I enquired with the contractor nearby about the cylinders and I was told that they are empty and are to be sent to the supplier. On close observation, I found that the valve discharge nozzle is having some water (there was rain on previous night) and small bubbles were being formed continuously.

From this I understood that though the cylinder is empty, it is not 100% empty and some leftover gas in the cylinder is getting expanded due to rise in ambient temperature. As the valve is not totally closed, the expanded gas is leaking out as bubbles through the water in the discharge nozzle.

This clearly demonstrates that though we assume empty cylinders are safe, they are not actually 100% empty and if the gas is toxic, then the little amount of gas leaking out due to sunlight exposure can harm the persons nearby. If the cylinders are full then they are hazardous and can endanger the persons around.

Similarly, being found on the roadside, any damage to the valve (breakage) can rocket the cylinder like missile and can hurt persons / damage equipment or property nearby or can have a domino effect. For this reason, the rules are specific that the unused cylinder valves should be protected with valve caps so that valves can't be exposed directly.

People talk about safety culture so much, but these small issues like valve caps, cylinder storage under sunshade, chaining the cylinders to prevent their fall, etc are not given due attention. Lip service alone will not improve safety culture. May be, talking about safety will bring admiration from listeners and even some appreciation by way of reward, but this will not help in improving the safety at ground level and all this admiration / appreciation / rewards will be washed off by any single accident and the same persons will admonish the in-charges of the area for not visualizing the hazards and not taking corrective measures for the safety of the people.
