Employees operated and maintained an ammonia refrigeration system. The refrigeration system contained approximately 12,700 pounds of ammonia. A Hansen Technologies model HVK5D/7 three inch gas powered suction stop valve replaced an existing valve in the rooftop evaporator valve group, identified as valve HV-12 within evaporator group EV-2. The employer's process safety information indicated that control valves were to be Danfoss valves. The process safety information was not updated with the replacement valve's information. This condition exposed employees to an ammonia hazard.
