Everybody says process safety management (PSM) without knowing or having commitment. Many may be thinking it as day-to-day plant operation. In this regard, to identify, evaluate and control hazards in chemical plants, OSHA has given guidelines and can be read here.
It must be understood that by doing PSM, we are doing favour to ourselves and not to others. Even, production cost can be brought down, if we do PSM sincerely and follow it. If we do not care to spillages/leakages of chemicals, air, steam; do not care to study in detail before going for a new process / chemical / modification; do not make checklists for operations, then it means that enough attention is not paid for plant operations and it adds to cost of production by way of wastage, inefficient operation, accidents, and so on.
We should not feel like Alice in the wonder land when the unidentified hazards manifest into incidents/ accidents. One may feel stressed to follow the safety principles all the while. But, the stress will be more and can also lead to penalties and punishments when there is loss of life/damage to environment/property.
Many times when we land into simple accidents outside factory, we vow not to repeat such mistakes. But, when we commit such mistakes in a factory, the consequences will be very high and at that time we can move the time back to correct our mistakes. There is no time machine yet available to correct ourselves otherthan following safety principles in toto.
