Text For Citation: 01 Item/Group: 002 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 from potential equipment failure related release from the failure of ammonia refrigeration components due to lack of markings and documentation of system markings and documentation. (a) Anhydrous Ammonia Refrigeration Systems: On or about January 13, 2025, inspection of the piping system on the roof identified that piping was inaccurately labeled and piping and instrumentation diagrams (P&ID)'s R106 & R105 did not reflect the current piping configuration associated with DR, HGD, HTRS, and the HTRL lines. The HTRL lines were label duplicatively and did not have unique identification. The P&IDs R106 & R105 did not have the correct nomenclature for each line in the system in that the 2 HTRL lines were label the same and could not be differentiated on the P&ID's. (b) Anhydrous Ammonia Refrigeration Systems: On or about January 13, 2025, inspection of the piping system on the roof, identified that P&IDs R106 & R105 did not reflect current piping configuration associated with DR, HGD, HTRS, HTRL, & HTRL. P&IDs R106 & R105 did not have the correct nomenclature for each line in the system in that the DR was represented as HTRS. (c) Anhydrous Ammonia Refrigeration Systems: On or about January 13, 2025, inspection of the piping system on the roof, identified that P&IDs did not reflect current piping configuration associated with DR. The DR was missing in P&ID R106 for the AU1, AU5, AU7, and AU8. (d) Anhydrous Ammonia Refrigeration Systems: On or about January 13, 2025, inspection of the piping system on the roof, identified that P&IDs did not reflect current piping configuration associated with LLTS. The LLTS was removed in the expansion of the system in 2013. (e) Anhydrous Ammonia Refrigeration Systems: On or about January 13, 2025, inspection of the piping system on the roof, identified that P&IDs R106 & R105 did not reflect current piping configuration associated with DR, HGD, HTRS, HTRL, & HTRL. P&IDs R106 & R105 did not have any diameter values for each line in the system.
