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 fire occurred during welding part of the p1 16" reversal project. Prior to welding occurring, a pump and associated piping were taken out of service to allow for the welding of two tees on june 8, 2012. A job plan and safe work permit were issued and atmospheric testing was performed prior to work commencing. No hydrocarbons were detected. Work began and a fire occurred during the welding of the second tee. The job was stopped and the pipeline technician discovered that the pump and piping had not been drained or purged. Prior to work resuming, the line was properly drained and purged. Specifically, a vacuum truck was used to remove the hydrocarbon liquids and dry ice was placed in the pipeline to remove carbon dioxide and hydrocarbon vapors. After atmospheric testing at the weld site revealed no hydrocarbons, welding was then resumed.
