Some problem at a downstream unit prevented us from slopping coker gas oil (CGO) for a period of time. To solve the problem a tanker was pulled up for slop catchment. A flexible hoze was attached to the vent line of the CGO slop line, and fitted with a valve.
Two days later one of the Process Controllers was injured (minor burn injuries) when the tanker primed during slop action.
- ALWAYS do a HAZOP! No matter how menial the task seems.
- Make sure that the people have the RIGHT safety equipment for the job.
- NEVER do an alteration without consulting the owner of the process i.e. the Process Controller.
