An investigation by Redstone Arsenal into the May 2010 explosion that killed two contractors blames Amtec Corp. for using unsuitable equipment and not developing adequate safety procedures for its use. The investigation determined that Amtec “exercised poor safety discipline” in its work with a rocket fuel component. The explosion that killed the two Amtec contractors, Jim Hawke and Jerry Grimes, involved attempts to remove ammonium perchlorate, a oxidizer used in solid rocket propellant, from weapons. The explosion killed the two men and destroyed a building on the premises.
