NEWPORT, Ind. -- A fire at the Newport Chemical Depot gutted a trailer used by workers who are razing the plant that produced the deadly VX nerve agent.

No one was injured in the fire this morning. Depot spokesman Dennis Lindsey said the fire posed no threat or danger to the public because nothing hazardous was stored inside the trailer.

Firefighters quickly extinguished the 6 a.m. fire, which appeared to have begun with an electrical short in a heating/air conditioning unit, Lindsey said.

The trailer, which was unoccupied at the time of the fire, is about three-quarters of a mile from the depot's cache of 1,269 tons of VX. The Army expects to begin neutralizing the deadly nerve agent this summer.

Workers who are tearing down the VX production plant used the trailer to change into work clothing, Lindsey said.

State and county authorities were routinely notified as soon as depot officials learned of the fire, Lindsey said.
