Text For Citation: 01 Item/Group: 002 Hazard:

29 CFR 1910.119(d)(3)(ii): The employer did not document that equipment complies with recognized and generally accepted good engineering practices (RAGAGEP): (a) On or about November 23, 2018, the employer did not document that the engine room, where the ammonia refrigeration equipment was located in the packing house, complied with the employers chosen RAGAGEP, such as but not limited to, IIAR 2-2014, Standard for Safe Design of Closed-Circuit Ammonia Refrigeration System (Section 6.10.4), which requires machinery room doors to be self-closing, tight-fitting. In addition, machinery room egress doors are required to be equipped with panic hardware and be side hinged to swing in the direction of egress. (b) On or about November 23, 2018, the employer did not document that the engine room, where the ammonia refrigeration equipment was located in the packing house, complied with the employers chosen RAGAGEP, such as but not limited to, IIAR 2-2014, Standard for Safe Design of Closed-Circuit Ammonia Refrigeration System (Section 6.14.5.1), which requires the machine room ventilation to maintain a negative pressure threshold while the ammonia system is operating to avoid migration of ammonia vapor to adjacent areas in the event of a leak. The employer failed to ensure negative pressure ventilation was maintained in the machinery room when a portion of the engine room wall was cut out in order to move two compressors out of the room. The hazardous conditions listed in the above instances exposed employees to toxic and flammable hazards in the event of an ammonia release.
