For those of you who have been around in the chemical industry for a long time, you will recall that prior to the nineties, process safety was managed in most companies by people who had vast experience and knowledge. Today, I see a dangerous trend - we are drowning in complex PSM systems that takes time to understand and given the high attrition rates, accidents continue to happen. I believe for a PSM system to succeed, there can never be a replacement for strong technical competency right up to the top of a company and that PSM systems must be simple, easy to understand and execute. It is not the number of elements you have in your PSM system or the Safety Integrity level that counts but the capacity to comprehend what the system is telling you.....!
