OSHA Ammonia Refrigeration Safety
29 CFR § 1910.119 Online Training Certification
Every year deaths and injuries occur from contact with both liquid and gas forms of ammonia used in refrigeration facilities during accidental releases. Because of the high pressures of refrigeration systems extra care must be taken while operating and maintaining these systems to prevent releases with potentially catastrophic consequences.
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.
