Food and beverage plants carry an unusual hazard profile — ammonia refrigeration under PSM, aggressive sanitation chemistry, wet environments and dust — sitting alongside food safety systems that already consume the compliance bandwidth.
Anhydrous ammonia above the threshold quantity pulls the whole facility into process safety management and usually EPA Risk Management Program as well. Many plants sit just above and have never formally determined it.
The highest-hazard work in the plant happens on third shift with the smallest crew and the least supervision — caustics, high-pressure washdown, and machine cleaning that requires lockout on equipment designed for continuous operation.
Cleaning equipment while it moves is faster, and the guarding designed for production does not accommodate cleaning access. This is where the amputations happen in this industry.
Dust hazard analysis requirements apply to organic dusts that most operators do not think of as explosive. Dust collection, housekeeping and ignition control are all in scope.
Slip exposure is constant and chronic, and sanitation chemical burns are underreported because crews treat them as routine.
A plant with a mature HACCP and SQF system often has almost nothing comparable for occupational safety, because the audit pressure only came from one direction.
We start with ammonia applicability and the sanitation shift, because that is where the serious exposure sits. PSM determination, mechanical integrity, management of change, and a lockout system that actually accommodates cleaning access rather than assuming it away.
Then the rest: dust hazard analysis, chemical management for sanitation, wet-environment controls, and a program structure that integrates with the food safety system you already run rather than duplicating it.
The threshold quantity for anhydrous ammonia in a process. Whether you are over depends on the total in the covered process, and how the process is defined matters. Document the determination either way.
Sanitation. Machine cleaning with inadequate energy control, on the shift with the least oversight, using the most aggressive chemistry in the building.
If you handle flour, sugar, starch, powdered dairy, spices or similar materials, almost certainly. Organic dusts are frequently more readily ignitable than operators assume.
They can own the coordination, but the technical requirements are genuinely different and the standards are unrelated. Pairing them with credentialed EHS oversight is the practical structure.
Yes, including sanitation shift observation, which is the only way to assess the work that actually carries the risk.
Twenty minutes first, to scope what a third-shift assessment would cover and whether ammonia puts you under PSM.
