Worker killed, others hurt in July explosion

Officials say explosion occurred during hot work on tank


MOSS POINT, Miss. (AP) – The U.S. Chemical Safety Board says a fatal July explosion at a fish processing plant on the Mississippi Coast occurred during “hot work” on a tank.

Hot work is defined as any burning, cutting, welding or other operation that is capable of initiating fires or explosions.

In statement released Tuesday, the board says the hot work at the Omega Protein plant in Moss Point ignited vapors inside the tank. The explosion left one worker dead and several others injured.

The Chemical Safety Board says the tank contained eight inches of a mixture of water and fish matter found to contain volatile fatty acids and offgassing of methane and hydrogen sulfide.

The board says no combustible gas testing was done on the contents of the tank before the hot work began.
