House No.4, the site of a four-alarm fire on April 22, 1967. A brick chimney arose from Boiler House No.4 and this stack was a familiar sight to westbound motorists on the Penrose Avenue Bridge as the word “GULF” was painted in large, white letters. Hydrocarbon vapors, emanating from Tank 231, accumulated in the area of the boiler house and were ignited by an unknown ignition source. A flame front followed the vapors back to Tank 231 causing fire at the tank’s vents and an explosion within the outer shell
