Text For Citation: 02 Item/Group: 001B Hazard:

29 CFR 1910.119(d)(3)(ii): The employer did not document that equipment complies with recognized and generally accepted good engineering practices. b) Engine Room - Main Doorway Entrance: The employer did not document that the plastic strips hanging loose at the main doorway entrance to the engine room and the inwardly-opening, non-self-closing metal door chained open next to that entrance complied with recognized and generally accepted good engineering practices, such as but not limited to Section 8.13.2 of ASHRAE 15-1994 Safety Standards for Refrigeration Systems which required that each refrigerating machinery room shall have tight-fitting doors which open outward, are self-closing if they open into the building, and that no openings exist that will permit passage of escaping refrigerant to other parts of the building. This condition which exposed employees to a toxic hazard was observed on or about 11/14/16. c) Engine Room - The employer did not document that the openings from the engine room through the electrical room which could permit passage of escaping anhydrous ammonia through the electrical room and then into the loading dock area complied with recognized and generally accepted good engineering practices, such as but not limited to Section 8.13.2 of ASHRAE 15-1994 Safety Standards for Refrigeration Systems which required that each refrigerating machinery room shall have tight-fitting doors which open outward, are self-closing if they open into the building, and that no openings exist that will permit passage of escaping refrigerant to other parts of the building. This condition which exposed employees to a toxic hazard was observed on or about 11/14/16. d) Engine Room - Ice Maker 5: The employer did not document that the pressure relief valve for the ice maker (set pressure 275 psig) which was used for the accumulator (maximum allowed working pressure 200 psig) complied with recognized and generally accepted good engineering practices, such as but not limited to Section 9.5.1 of ASHRAE 15-1994 Safety Standards for Refrigeration Systems which required that pressure relief valves shall start to function at a pressure not to exceed the design pressure of the parts of the system protected. This condition which exposed employees to a toxic hazard was observed on or about 12/19/17. e) Engine Room - Ice Maker 6: The employer did not document that the pressure relief valve for the ice maker (set pressure 275 psig) which was used for the accumulator (maximum allowed working pressure 200 psig) complied with recognized and generally accepted good engineering practices, such as but not limited to Section 9.5.1 of ASHRAE 15-1994 Safety Standards for Refrigeration Systems which required that pressure relief valves shall start to function at a pressure not to exceed the design pressure of the parts of the system protected. This condition which exposed employees to a toxic hazard was observed on or about 12/19/17. f) Engine Room - Ice Maker 7: The employer did not document that the pressure relief valve for the ice maker (set pressure 275 psig) which was used for the accumulator (maximum allowed working pressure 200 psig) complied with recognized and generally accepted good engineering practices, such as but not limited to Section 9.5.1 of ASHRAE 15-1994 Safety Standards for Refrigeration Systems which required that pressure relief valves shall start to function at a pressure not to exceed the design pressure of the parts of the system protected. This condition which exposed employees to a toxic hazard was observed on or about 12/19/17. g) Engine Room - Ice Maker 8: The employer did not document that the pressure relief valve for the ice maker (set pressure 275 psig) which was used for the accumulator (maximum allowed working pressure 200 psig) complied with recognized and generally accepted good engineering practices, such as but not limited to Section 9.5.1 of ASHRAE 15-1994 Safety Standards for Refrigeration Systems which required that pressure relief valves shall start to function at a pressure not to exceed the design pressure of the parts of the system protected. This condition which exposed employees to a toxic hazard was observed on or about 12/19/17. h) Engine Room- Frick Compressor RC-1 Oil Cooler: The employer's process safety information indicated that the length of the installed relief valve outlet piping of 23 feet was greater than the maximum allowable length for the relief valve outlet piping of 9 feet. The employer did not document that the length of the installed relief valve outlet piping complied with recognized and generally accepted good engineering practices, such as but not limited to Section 9.7.8.5 of ASHRAE -15-2000 Safety Standards for Refrigeration Systems. This condition which exposed employees to a toxic hazard was observed on or about 2/21/17. i) Engine Room - Frick Compressor RC-2 Oil Cooler: The employer's process safety information indicated that the length of the installed relief valve outlet piping of 31 feet was greater than the maximum allowable length of 9 feet for the relief valve outlet piping. The employer did not document that the length of the installed relief valve outlet piping complied with recognized and generally accepted good engineering practices, such as but not limited to Section 9.7.8.5 of ASHRAE -15-2000 Safety Standards for Refrigeration Systems. This condition which exposed employees to a toxic hazard was observed on or about 2/21/17. j) North and South Freezers - Evaporators (AU-1, AU-2, AU-3, AU-4, AU-5, AU-6, AU-7 and AU-8): The employer did not document that the unlabeled ammonia refrigeration piping located in the freezers and was connected to the evaporators complied with recognized and generally accepted good engineering practices, such as but not limited to IIAR - 114 -1991 Identification of Ammonia Refrigeration Piping and System Components, Section 2.0), which required all ammonia system piping mains, headers and branches to be identified as to the physical state of the refrigerant (i.e. vapor, liquid, etc.), the relative pressure level of the refrigerant and the direction of flow. This condition which exposed employees to a toxic hazard was observed on or about 2/14/17. l) Ammonia Refrigeration System - Covered Process: The employer's "Process Safety Information" document (pg. 12) did not contain accurate information in that it identified the maximum allowable working pressure (mawp) for Vogt Ice Makers 5, 6, 7, and 8 as 275 psig when the actual mawp was 200 psig as identified on the pressure vessel nameplate; on or about December 19, 2016. REPEAT STATEMENT: Arctic Glacier U.S.A., Inc. was previously cited for a violation of this occupational safety and health standard or its equivalent standard 29 CFR 1910.119(d)(3)(ii), which was contained in OSHA inspection number 623559, citation number 1, item number 8b and was affirmed as a final order on June 28, 2013, with respect to a workplace located at 500 Fenimore Road, Mamaroneck, NY 10543.
