On May 4, 1988, a fire followed by several explosions occurred at the Pacific Engineering and Production Company of Nevada (PEPCON) chemical plant in Henderson, Nevada. The disaster caused two fatalities, 372 injuries, and an estimated $100 million of damage. A large portion of the Las Vegas Valley within a 10-mile (16 km) radius of the plant was affected, and several agencies activated disaster plans.
