Abstract: At 11:00 a.m. on October 8, 2015, four employees were welding and cutting flanges on the south header section of a slug catcher assembly. An employee began to weld a 3-inch flange connected to a slug catcher which had previously contained flammable hydrocarbon sludge. An arc from the welder may have been the ignition source that triggered an explosion of vapors from the flammable hydrocarbon sludge material in the slug catcher. Four employees were killed in the explosion.
