Giant Industries Refinery Explosions and Fire
Gallup, NM, April 8, 2004
Giant Industries Refinery Explosions and Fire
April 8, 2004: Explosions and fire damage the alkylation unit at the Giant Industries gasoline refinery near Gallup, NM, seriously injuring four workers.

Incident Description
On April 8, 2004, four workers were seriously injured when highly flammable gasoline components were released and ignited at the Giant Industries Ciniza refinery, east of Gallup, New Mexico. The release occurred as maintenance workers were removing a malfunctioning pump from the refinery's hydrofluoric acid (HF) alkylation unit. Unknown to personnel, a shut-off valve connecting the pump to a distillation column was apparently in the open position, leading to the release and subsequent explosions.

Investigation Status
The CSB issued a case study report on this accident on October 26, 2005.
