B-109 Audits


IIAR Bulletin 109 (B-109) Audits

The International Institute of Ammonia Refrigeration (IIAR) issues their Bulletins as useful and informative documents written to serve as best practice guidelines where no other standard or guidance exists.  The IIAR Bulletin 109 (B-109) provides guidance on minimum safety criteria for a safe ammonia refrigeration system.  These criteria are intended to be applied during annual and five-year safety inspections and audits, which are referred to as B-109 Audits.  The criteria contain guidelines for compressors, condensers, heat exchangers, pressure vessels, evaporators, refrigerant pumps, liquid level indicators, piping systems, ventilation systems, pressure-relief devices, and general system safety requirements.
