Text For Citation: 01 Item/Group: 003 Hazard:

OSH ACT of 1970 Section (5)(a)(1): The employer did not furnish employment and a place of employment which were free from recognized hazards that were causing or likely to cause death or serious physical harm to employees in that employees were exposed to anhydrous ammonia contact, asphyxiation and explosion hazards related to potential release from the ammonia refrigeration system. (a) On or about June 25, 2025, the employer had not preformed frequent and periodic testing on vessel HTR01 (National Board NO: 11045, Serial NO:98206) to ensure that the vessel was maintained and operated within the design specifications. This pressure vessel, also known as the liquid receiver, had never been inspected to determine if under insulation exterior corrosion and pitting related deterioration exceeded minimum wall thickness. Failure to inspect critical process equipment, such as liquid receiver pressure vessels, increases the risk for loss of containment and release from the covered process and potential exposure for employees to ammonia contact, asphyxiation and explosion hazards.
