An effective process safety management program requires a systematic approach to evaluating the whole chemical process. The following references aid in evaluating process hazards in the workplace.

  • Ammonia Refrigeration. OSHA eTool.
  • Risk Management Program Guidance. Environmental Protection Agency (EPA).
    • General Risk Management Program Guidance. Contains an updated risk management program, which includes an appendix specifically addressing ammonia refrigeration facilities. While this guidance is primarily designed to assist with the development and implementation of a risk management plan as required by the EPA, much of the information can also be used by those who are required to comply with the OSHA Process Safety Management Standard (29 CFR 1910.119).
      • Appendix E: Supplemental Risk Management Program Guidance for Ammonia Refrigeration Facilities (PDF).

        NOTE: This appendix replaces the former stand-alone document "Risk Management Program Guidance for Ammonia Refrigeration." This appendix is intended for facilities with ammonia refrigeration systems (e.g., food processors and distributors, refrigerated warehouses). It covers only anhydrous ammonia and provides offsite consequence analyses that are specific to the ways in which ammonia is handled in an ammonia refrigeration system.

  • Model Risk Management Program and Plan for Ammonia Refrigeration (PDF). Environmental Protection Agency (EPA), (May 1996). Helps owners and operators of ammonia refrigeration facilities comply with the OSHA Process Safety Management Standard (29 CFR 1910.119) and EPA's General Risk Management Program Guidance (40 CFR Part 68). Specific guidance is given on how to perform the Hazard Assessment, and the requirement for a Management System, Prevention Program, and Emergency Response Plan. Also included is a brief report of past accidental releases of ammonia and their root causes from EPA's Accidental Release Information Program (ARIP) database.
