Text For Citation: 01 Item/Group: 007 Hazard:

29 CFR 1910.119(e)(3)(iii): The process hazard analysis did not address engineering and administrative controls applicable to the hazards and their interrelationships such as appropriate application of detection methodologies to provide early warning of releases. (a) On or about May 12, 2021, at Limetree Bay Refining, LLC., Delayed Coker Unit (DCU) - The employer's PHA failed to evaluate the absence of administrative controls applicable to the hazards of the Coker Unit quenching process when too much quench water entered the Coke Drum (D-8504) due to a bypass valve and blind being inadvertently left open. PHA did not address the bypass valve or blind at all. The valve was not on the car seal list, the blind was not on blind list survey and instructions were not included in the operating procedure to verify that valve and blind were closed. (b) On or about May 12, 2021, at Limetree Bay Refining, LLC., Delayed Coker Unit (DCU) - The employer's PHA failed to evaluate the absence of administrative controls applicable to the hazards of insufficient Coke Drum temperature leading to a tarry drum. In particular, the employer did not have procedures for handling and responding to tarry drums or high level in Coke Drum. (c) On or about May 12, 2021, at Limetree Bay Refining, LLC., Flare No. 8 Complex - The employer's PHA failed to evaluate the absence of engineering and administrative controls applicable to the hazards of thermal radiation flux levels from flaring exposing personnel to burn and toxic vapors. In particular, the employer did not provide protection measures such as shielding or installing a boundary/barricade to restrict personnel and signage warning of the potential of thermal radiation exposure for areas near Flare No. 8. (d) On or about May 12, 2021, at Limetree Bay Refining, LLC., Delayed Coker Unit (DCU) - The employer's PHA failed to evaluate the absence of engineering and administrative applicable to the hazard of toxic gases (H2S and benzene) entering the Coker Unit Operator Shelter (Building # 8503) during an emergency release from process equipment in the Coker Unit. In particular, the employer failed to ensure that Building #8503 had sufficient mitigation systems for a shelter in place location in the event of a toxic release - it was not equipped with appropriate engineering controls to detect, mitigate and reduce hazards to workers in the event of a toxic release.
