The following is a list of key safety measures developed by EPA in coordination with the International Institute of Ammonia Refrigeration (IIAR). They are measures that EPA and IIAR agree are required elements for ammonia refrigeration facilities (regardless of an ammonia refrigeration system’s age or size) for the system to meet the requirements of 40 C.F.R. Part 68 or the General Duty Clause of 42 U.S.C. ยง 7412(r)(1). The list is not intended to be a complete list of required and important safety measures that address hazards at ammonia refrigeration facilities, but rather a subset of easily verifiable items that could help facilities prevent ammonia releases and prepare for any releases that do occur.
