Way back in 2015, I shared a practice I have used for most of my career, after working a major turnaround back in the 1990’s. And anyone who has worked a turnaround at a processing plant will certainly understand what I am trying to address with this practice. Bottom line, we should NEVER put the PRCS DANGER sign directly on the entry portal cover! This sets us up for having many OPEN and UNLABELED PRCSs. The revised drawing below is what I provide clients to include in their PRCS programs so they can avoid making this very common error. The drawing shows a tank with a manway attached to a davit arm, which can be swung out of the way, creating another potential blind spot for our DANGER sign.
