Narrative
In reference to parts a(6), f,and I, this report is being made as part of a comprehensive review and analysis of prior incidents or near misses involving flash fire or ignition of flammable vapors, pursuant to a compliance order issued by PHMSA (cpf no. 4-2014-5017). A flash fire occurred at a recently completed weld when air movers were being relocated. A valve (hv-3) upstream of the weld location was not sealing resulting in leaking hydrocarbons. Air movers were utilized to pull the hydrocarbon vapors away from the welding location. Prior to the start of welding, lel levels were checked initially, documented on the permit and periodically throughout the welding job. These checks indicated a 0% lel reading while the air movers were in operations. When the air movers were shutdown to accommodate moving one of the air movers, hydrocarbon vapors came in contact with hot metal (post welding) at the weld location and ignited. Post incident, continuous gas monitoring performed in the work area indicated a 0% lel readings while the air movers were in operations.
