As we know “human factors” are specifically called in the OSHA’s PSM standard and EPA’s Risk Management Plan and even more specifically they are part of our Process Hazards Analysis (PHA). However, many do not understand what “human factors” are all about, so I thought I would share another picture I captured in my travels to help demonstrate a serious error in “human factors”. Do you see the “conflict” in this picture? What am I suppose to do? Do we have conflicts like this in our covered process areas or in our administrative controls like our Safe Work Practices, Operating Procedures, and/or maintenance procedures? What would you in this situation?
