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

29 CFR 1910.119(d)(2)(i)(E): The employer failed to perform an evaluation of the consequences of deviations, including those affecting the safety and health of employees: (a) On or about May 12, 2021 at Limetree Bay Refining, LLC., Delayed Coker Unit (DCU) - the employer failed to compile complete and accurate information concerning the technology of the DCU to include an evaluation of the consequences of deviations, including those affecting the safety and health of employees. The employer did not include an evaluation of the consequences of exceeding the quench water flowrate during an abnormal, or "tarry drum," quenching scenario. Failure to evaluate consequences of exceeding safe operating limits for quench water flowrate can cause an overfill/overpressure scenario, 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 information concerning the technology of the DCU to include an evaluation of the consequences of deviations, including those affecting the safety and health of employees. The employer did not include an evaluation of the consequences of exceeding the design metal temperature of the Coker Feed Furnace (H-8501B) tube and swing elbow. Failure to accurately establish safe operating limits for heater tubes/elbows and evaluate consequences of exceeding limits can cause catastrophic tube rupture, and expose employees to fire, explosion, and toxic hazards. (c) On or about May 12, 2021 at Limetree Bay Refining, LLC., Delayed Coker Unit (DCU) - the employer failed to compile complete and accurate information concerning the technology of the DCU to include an evaluation of the consequences of deviations, including those affecting the safety and health of employees. The employer did not include an evaluation of the consequences of low pilot fuel gas to Coker Feed Furnace (H-8501B) during coke drum filling. Failure to accurately establish safe operating limits for H-8501B's pilot fuel gas and evaluate consequences pilot gas can expose employees to fire, explosion, and toxic hazards. (d) On or about May 12, 2021 at Limetree Bay Refining, LLC., Delayed Coker Unit (DCU) - the employer failed to compile complete and accurate information concerning the technology of the DCU to include an evaluation of the consequences of deviations, including those affecting the safety and health of employees. The employer did not include an evaluation of the consequences of low Coker Feed Furnace (H-8501B) process outlet temperature (also known as coil outlet temperature). Failure to accurately establish safe operating limits for H-8501B's COT and evaluate consequences of low drum inlet temperature can lead to abnormal coke drum scenario, and expose employees to fire, explosion, and toxic hazards. (e) On or about May 12, 2021 at Limetree Bay Refining, LLC., Delayed Coker Unit (DCU) - the employer failed to compile complete and accurate information concerning the technology of the DCU to include an evaluation of the consequences of deviations, including those affecting the safety and health of employees. The employer did not include an evaluation of the consequences of high temperature and high pressure for Coke Drum overhead vapor line to Blowdown Tower (T-8512) during an abnormal, or "tarry drum," quenching scenario. Failure to establish accurate safe operating limits and evaluate consequences of high temperature and high pressure can exceed design temperature and pressure of process equipment resulting in loss of containment, and expose employees to fire, explosion, and toxic hazards. (f) On or about May 12, 2021 at Limetree Bay Refining, LLC., Delayed Coker Unit (DCU) - the employer failed to compile complete and accurate information concerning the technology of the DCU to include an evaluation of the consequences of deviations, including those affecting the safety and health of employees. The employer did not include an evaluation of the consequences of exceeding the process temperature of the overhead vapor line to the Coker Fractionation Tower (T-8501). Failure to establish accurate safe operating limits and evaluate consequences of high temperature can exceed design temperature of piping resulting in loss of containment, and expose employees to fire, explosion, and toxic hazards. (g) On or about May 12, 2021 at Limetree Bay Refining, LLC., Delayed Coker Unit (DCU) - the employer failed to compile complete and accurate information concerning the technology of the DCU to include an evaluation of the consequences of deviations, including those affecting the safety and health of employees. The employer did not include an evaluation of the consequences of high pressure in Coke Drum (D-8504) overhead vapor line (PI-4010) during an abnormal, or "tarry drum" quenching scenario. Failure to establish accurate safe operating limits and evaluate consequences of high pressure can exceed design pressure of piping resulting in loss of containment, and expose employees to fire, explosion, and toxic hazards. (h) On or about May 12, 2021 at Limetree Bay Refining, LLC., Delayed Coker Unit (DCU) - the employer failed to compile complete and accurate information concerning the technology of the DCU to include an evaluation of the consequences of deviations, including those affecting the safety and health of employees. The employer did not include an evaluation of the consequences of high pressure in Blowdown Drum Overhead Separator (D-8513) overhead line (PC-4653) and flare line (PC-4693) during an abnormal, or "tarry drum," quenching scenario. Failure to establish accurate safe operating limits and evaluate consequences of high pressure can exceed design pressure of piping resulting in loss of containment, and expose employees to fire, explosion, and toxic hazards. (i) On or about May 12, 2021 at Limetree Bay Refining, LLC., Flare No. 8 Complex - the employer failed to compile complete and accurate information concerning the technology of the Flare No. 8 to include an evaluation of the consequences of deviations, including those affecting the safety and health of employees. The employer did not include an evaluation of the consequences of high level in Coker Flare Knockout Drum (D-8702) and FCC Flare Knockout Drum (D-7941). Failure to establish accurate safe operating limits and evaluate consequences of exceeding limits for flare knockout drum level causes liquid carryover to flare header, flaming rain and expose employees to fire, explosion, toxic and respiratory hazards.
