Ammonium perchlorate was involved in the 1988 disaster that took place in what Nevada city?
PEPCON disaster The PEPCON disaster was an industrial disaster that occurred in Henderson, Nevada on May 4, 1988 at the Pacific Engineering and Production Company of Nevada (PEPCON) plant. The conflagration and subsequent explosions killed two people, injured 372 others, and caused an estimated US$100 million of damage. A large portion of the Las Vegas Valley within a 10 mi radius of the plant was affected, and several agencies activated disaster plans.
L'Ambiance Plaza collapse The L'Ambiance Plaza collapse was one of the worst disasters in modern Connecticut history. L'Ambiance Plaza was a 16-story residential project under construction in Bridgeport, Connecticut at the corner of Washington Avenue and Coleman Street. Its partially erect frame completely collapsed on April 23, 1987, killing 28 construction workers. Failure was possibly due to high concrete stresses on the floor slabs by the placement process resulting in cracking ending in a type of punch through failure. Several observers suggested the collapse was preventable and highlighted the deficiencies of the lift slab construction technique. This collapse prompted a major nationwide federal investigation into lift slab construction as well as a temporary moratorium on its use in Connecticut.
