Process Safety - only for chemical industries?

By the name process safety, one may think it is only for chemical industries and not for others. In a broader sense, process can be a system. Then OHSAS 18001 / IS 18001 will come into picture. Simplified, it is PDCA cycle i.e Plan, Do, Check and Act. We have to list out steps involved in all activities and then plan for improving the system to eliminate / minimize hazards. If we are thorough, we can even apply this process safety for our body function. The thought process will extend to all fields and there are no boundaries where we can not apply process safety. Better luck.
