Text For Citation: 01 Item/Group: 004 Hazard:

29 CFR 1910.119(d)(3)(i)(G): The employer's material and energy balances (M&EB) were not accurate and did not reflect the current crude composition and operating conditions: (a) On or about May 12, 2021, at Limetree Bay Refining, LLC., Delayed Coker Unit (DCU) - the employer failed to update their material and energy balances (M&EB) for the DCU and Flare No.8 after the crude composition changed. Failure to compile complete accurate M&EB results in incorrect process conditions being used for process hazard analyses (PHAs), relief system design basis and calculations, and safe operating limits for equipment, exposing employees to the hazard of explosions, fires from LPG, naphtha, gas oils, coke and toxic gases (H2S, benzene, and carbon monoxide) while working in the DCU. (b) On or about May 12, 2021, at Limetree Bay Refining, LLC., Delayed Coker Unit (DCU) - the employer failed to compile complete M&EB information that included normal operating pressure, viscosity of stream, specific heat ratio Cp/Cv, and compressibility factor for the gaseous phase process streams in the DCU. Failure to compile complete accurate M&EB results in using incorrect process conditions in the PHAs, relief system design basis and calculations, and safe operating limits for equipment in operating procedures, exposed employees to the hazard of explosions, fires from LPG, naphtha, gas oils, coke and toxic gases (H2S, benzene and carbon monoxide) while working in the DCU.
