The CSB will discuss its investigation of the November 19, 2023, fired heater tube rupture at a refinery in Martinez, California. The incident occurred during the initial startup of a renewable diesel hydroprocessing unit, resulting in a fire that seriously injured one employee. Topics will include fired heater safe operating limits, worker proximity to fired heaters, safety instrumented systems that detect low process flow into fired heaters, burner operation, valve misalignments, and corporate oversight.

Participants will: Gain an understanding of both the process-side and combustion-side causes that contributed to the tube rupture; Identify potential deficiencies that may exist at their own units; and Review the CSB’s industry recommendation to API for suggested revisions to API RP 556 (Instrumentation, Control, and Protective Systems for Gas Fired Heaters).
