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

29 CFR 1910.119(d)(3)(ii): The employer shall document that equipment complies with recognized and generally accepted good engineering practices: At a facility located at N3620 County Road D, New London, WI 54961; the employer did not document that equipment complies with recognized and generally accepted good engineering practices (RAGAGEP): a) The Low Temperature Accumulator Vessel (V-5). The employer failed to document compliance with employer's chosen RAGAGEP including ASME Section VIII, Division 1 (2019) - Boiler Pressure Vessel Code UCS-66 and IIAR 2 (2014) Section 9.1.5 when the Low Temperature Accumulator Vessel (V-5) was operated below the vessel's stamped minimum design metal temperature (MDMT). In addition, the employer did not have the vessel evaluated by its manufacturer or other qualified design professional to ensure the vessel could be operated below its MDMT, which could affect the structural integrity of the vessel. This hazardous condition exposed employees to the hazard of inhalation and burns from ammonia liquid and vapors. b) The Low Temperature Accumulator Vessel (V-5) - The employer failed to document compliance with employers chosen RAGAGEP including ASME Section VIII, Division 1 Boiler Pressure Vessel Code and IIAR 2 (2014) Section 12.2.6 when the Low Temperature Accumulator Vessel (V-5) was not designed with a minimum of 1/16 inch corrosion allowance to ensure longevity of the vessel's service life in situations where external corrosion occurs. This hazardous condition exposed employees to the hazard of inhalation and burns from ammonia liquid and vapors. c) d) Insulation on vessel and piping: the Medium Temperature Accumulator (Vessel 4), the Low Temperature Accumulator (Vessel 5), and portions of their associated piping. The employer failed to document compliance with employer's chosen RAGAGEP, Tyson's Insulation Specification, and IIAR 2 (2014) - Standard for Safe Design of Closed-Circuit Ammonia Refrigeration Systems, Section 5.10.1 when it did not mitigate condensation and excess frost buildup on the vessels and associated piping. This hazardous condition exposed employees to the hazard of inhalation and burns from ammonia liquid and vapors.
