At 1240 on February 1, 1972, the tankship V A Fogg departed Freeport Texas en route to the Gulf of Mexico to clean cargo tanks that carried benzene residue. The vessel was due to arrive in Galveston Texas at 0200 on Febrary 2. At approximately 1545, February 1, the V A Fogg suffered multiple explosions and sank. All 39 persons aboard died as a result of this casualty.

The National Transportation Safety Board determines that the probable cause of the initial and subsequent explosion was the ignition of benzene vapors which were present both within the open cargo tanks [and] on the main deck of the tankship. The investigative record in this case does not contain sufficient information to determine the ignition source of the initial explosion.

CTX has not seen the NTSB report, but it probably does not add much. The xylene must have been the main energy source. Ship was undoubtedly not inerted, even tho this was 3 years after the Mactra/Marpessa/Kong Haakon.
