REDSTONE ARSENAL, Ala. (May 5, 2010) -- At about 8:45 a.m. today, the Redstone Arsenal Directorate for Emergency Services responded to a fire at Building 7352, an Aviation and Missile Research, Development, and Engineering Center facility.

There were two AMRDEC contractors on site when the explosion occurred, both were injured. A third employee was in close proximity but was not injured. One of the injured was transported by Med-Flight to University of Alabama at Birmingham Hospital. The other injured was transported by Med-Flight to Huntsville Hospital and has since been transferred to UAB Hospital. Both are currently at UAB's Burn Center. All involved are accounted for. There were no fatalities.

We extend our deepest sympathy to the families and friends of those who have been affected by this accident.

The employees were working on demilitarization operations that involved ammonia perchlorate, an oxidizer used in solid rocket propellant.

The building had recently passed safety inspections and was designed specifically to minimize the impact of possible explosions.

Arsenal officials are continuing to investigate. No names will be released at this time.

More information will be provided as soon as it is available.
