Anhydrous ammonia is widely used as refrigerant in industrial facilities such as:
- meat, poultry, and fish processing facilities,
- dairy and ice cream plants,
- wineries and breweries,
- fruit juice, vegetable juice, and soft drink processing facilities,
- cold storage warehouses,
- other food processing facilities,
- seafood processing facilities aboard
ships, and
- petrochemical facilities.
Ammonia refrigeration systems with 10,000 pounds or
more of ammonia are a covered process subject to the requirements of the Process Safety
Management Standard [1910.119]. Many of these
requirements are identified in this e-tool as possible controls and are useful as recommended practices whether or not the ammonia refrigeration
system is a covered process. As mentioned in
1910.119 Appendix C, smaller businesses which may have limited resources
might consider reductions in inventory or dispersing inventory to several
locations to reduce the risk from an ammonia release.
This eTool is designed to assist employers and employees in identifying and controlling the hazards
associated with the operation and maintenance of ammonia refrigeration
systems. This eTool consists of Ammonia Receiving and
Storage and Emergency Response
modules. Other operations include condenser area, piping and pressure
vessels, refrigeration spaces, and the machine room.
This eTool is a product of the
OSHA and The Dow Chemical Company and the
OSHA and the American Meat Institute Alliances.
