Summary
Two employees entered a rig mud pump suction tank for cleaning after permit completion and review of a lock-out JSA. An overlooked pressure-relief discharge connection led into the compartment from an unisolated pump whose bleed-off line remained unopened. A supervisor recognised the danger and removed the employees before an incident occurred.
