IIAR
Ammonia Refrigeration Library. Bulletin No. 109. Guidelines for IIAR Minimum Safety Criteria for a Safe Ammonia Refrigeration System. IIAR (1997, October), 9 pages. This bulletin embraces an IIAR goal of ensuring that ammonia refrigeration systems are engineered, constructed and operated in a safe manner. This
bulletin provides detailed lists of items to consider when designing, inspecting, or operating a system. Housekeeping, recordkeeping, code considerations and personnel safety equipment are some of the safety issues addressed. The bulletin also provides inspection checklist forms for
compressors, condensers, evaporators, vessels and heat exchangers to check system installation against recognized industry safety requirements.
