An interesting comparison to OSHA NEP results for the Ammonia refrigeration industry. From July 2009 to June 2011, Workplace Health and Safety Queensland (WHSQ) conducted an audit and inspection program at 102 facilities using anhydrous ammonia-based industrial refrigeration systems. Facilities included a range of food processors (meat, dairy, processed foods), cold stores, and ice works. The program was developed in response to a number of significant ammonia-related incidents occurring in Queensland.
