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

29 CFR 1910.119(d)(2)(i)(D): Safe upper and lower limits for such items as temperature, pressures, flows, or compositions pertaining to the technology of the process were not compiled before conducting any process hazard analysis required by this standard: (a) On or about May 12, 2021, at Limetree Bay Refining, LLC., Delayed Coker Unit (DCU) - the employer failed to compile complete and accurate safe upper and lower limits for such items as temperatures, pressures, flows, or compositions for the DCU. The employer did not compile complete information on low and high pilot gas pressure for the Coker Feed Furnace (H-8501B). Failure to establish accurate safe operating limits for H-8501 pilot gas system to ensure it alarms and trips at the correct pressure can lead to process upsets, and expose employees to fire, explosion and toxic hazards. (b) On or about May 12, 2021, at Limetree Bay Refining, LLC., Delayed Coker Unit (DCU) - the employer failed to compile complete and accurate safe upper and lower limits for such items as temperatures, pressures, flows, or compositions for the DCU. The employer did not compile accurate information on the process's technology, including upper and lower limits for injecting antifoam into Coke drum during Coke fill to prevent foam over. Failure to establish accurate safe operating limits for antifoam could result in overfill of Coke Drums and expose employees to fire, explosion, and toxic hazards. (c) On or about May 12, 2021, at Limetree Bay Refining, LLC., Flare No. 8 Complex - the employer failed to compile complete and accurate safe upper and lower limits for such items as temperatures, pressures, flows, or compositions for the Flare No.8. The employer did not compile accurate information on the process's technology, including upper and lower limits for level in Coker Flare Knockout Drum (D-8702) and FCC Flare Knockout Drum (D-7941). Failure to establish accurate safe operating limits for flare knockout drum level could overfill drums, cause liquid carryover to flare, flaming rain and expose employees to fire, explosion, toxic and respiratory hazards.
