Notes/Remedial Actions

RQ. The Coker Unit was shutdown in an emergency fashion while the fire was controlled and extinguished by the refinery's in-house fire brigade. Disciplinary actions were taken towards the operator and the supervisor of the Coker Unit for not following established procedures. The Coke Pot procedure was enhanced by adding another layer of protection via the requirement to physically lock "closed" the Coke Pot valves prior to unlocking the drain valves.
