BSEE: Poor preparation prior to hot work leads to fires
Recently, several fires occurring during hot work have been reported to BSEE. BSEE defines hot work as any job with the potential to create an ignition source, such as an open flame, sparks, or high temperatures. Examples of hot work include welding, using acetylene torches, and grinding and cutting metal.
Incident 1: As a construction crew removed skid pads with a torch on the top deck, slag and sparks fell through the grating onto the manway cover of the water skimmer below, igniting a fire. The fire self-extinguished shortly thereafter as the fire watch was securing a dry chemical fire.
