Review the checklist below to ensure your facility is free of the most common ammonia safety hazards:

  1. Clean floors, free of oil and water
  2. Sufficient pipe quality beneath insulation (controlled with spot checks for corrosion under insulation (CUI)
    or the utilization of a corrosion inhibitor/ stainless steel piping)
  3. Pipes properly labeled and marked per International Institute of Ammonia Refrigeration (IIAR) Bulletin No. 114
    Equipment operates within design parameters, temperatures ranges
  4. Personnel practices maintenance cycling program on valves, regularly opening and closing valves so they
    don’t sit in one position for too long
  5. Clear escape routes from areas with ammonia present (no boxes in front of exits)
  6. Personnel and operators are sufficiently trained on ammonia refrigeration operations and safety awareness.
  7. Safe access to frequently used valves, equipment for maintenance.
  8. Items that require maintenance are accessible from the ground
  9. Items up high have a catwalk or a clear path accessible via a scissor lift or ladder
  10. Complete annual testing on leak detection systems to ensure alarms work properly Pipe plug or cap on all valves open to the atmosphere Self-closing, spring-loaded valves to prevent the presence of open oil draining valves.
  11. Gas mask systems readily accessible, close to ammonia source
  12. Piping and components free of heavy ice buildup, added weight
  13. Complete annual safety switch testing
  14. Closed electrical cabinets
