If we spend enough time in chemical plants, we will encounter a widespread, albeit severe, human failure regarding a “safety-critical instrument.”  I am referring to the IMPROPER placement of personal gas monitors.  Nine times out of 10, where do we find these personal gas monitors on the worker’s body?  I am betting your experiences are…...

This means the…...

This was another WRONG CHEMICAL—WRONG TANK incident at a resort. It was an unloading accident, and “human error” was said to have caused it. The chemical leak is believed to have resulted from hydrochloric acid being accidentally poured into a chlorine tank during a delivery. The incident, attributed to human error, is under thorough investigation…...
