Text For Citation: 01 Item/Group: 001A Hazard:

29 CFR 1910.119(d)(3)(ii): The employer did not document that equipment complies with recognized and generally accepted good engineering practices: a) In the Engine Room, on or about January 18, 2023, the employer did not comply with their chosen recognized and generally accepted good engineering practices (RAGAGEP) ANSI/IIAR 2 - 2008 Equipment, Design, and Installation of Closed-Circuit Ammonia Mechanical Refrigerating Systems, Section 13.2.1.3, because there is not a supervised alarm system activated when their mechanical ventilation system fails. b) In the Engine Room, on or about January 18, 2023, the employer did not comply with their chosen recognized and generally accepted good engineering practices (RAGAGEP) ANSI/IIAR 2 - 2008 Equipment, Design, and Installation of Closed-Circuit Ammonia Mechanical Refrigerating Systems, Section 13.2.1.4, because there are no emergency remote controls for the mechanical ventilation system located outside the Engine Room. c) In the Engine Room, on or about January 18, 2023, the employer did not comply with their chosen recognized and generally accepted good engineering practices (RAGAGEP) ANSI/IIAR 2 - 2008 Equipment, Design, and Installation of Closed-Circuit Ammonia Mechanical Refrigerating Systems, Section 13.2.3.1, because their Engine Room ammonia detection system does not actuate the two emergency up blast fans. d) In the Engine Room, on or about January 18, 2023, the employer did not comply with their chosen recognized and generally accepted good engineering practices (RAGAGEP) ANSI/IIAR 2 - 2008 Equipment, Design, and Installation of Closed-Circuit Ammonia Mechanical Refrigerating Systems, Section 13.2.3.2, because their continuously run ventilation fans did not provide a total ventilation rate at least equal to the larger of the two rates in Section 13.2.3.3. e) In the Engine Room, on or about January 18, 2023, the employer did not comply with their chosen recognized and generally accepted good engineering practices (RAGAGEP) ANSI/IIAR 2 - 2008 Equipment, Design, and Installation of Closed-Circuit Ammonia Mechanical Refrigerating Systems, Section 13.2.3.4, because the normal (non-emergency) ventilation rate does not provide normal ventilation volumes equal to the larger of the volumes in Section 13.2.3.4. f) In the Engine Room, on or about January 18, 2023, the employer did not comply with their chosen recognized and generally accepted good engineering practices (RAGAGEP) ANSI/IIAR 2 - 2008 Equipment, Design, and Installation of Closed-Circuit Ammonia Mechanical Refrigerating Systems, Section 13.2.3.9, because an Engine Room intake louvre is positioned adjacent to the air compressor exhaust fan discharge. Failure to ensure that the Engine Room mechanical ventilation system complies with their chosen RAGAGEP can result in employee exposure to anhydrous ammonia while inside the Engine Room. Exposure to ammonia can result in inhalation hazards which can result in serious injuries or death.
