Located north of the city of Concord, California, this shipyard was established in 1942. The station was a very important armament storage depot during World War II, but it was also a key site during the Korean War and the Vietnam War. The shipyard was the subject of a protest against the shipment of weapons to Central America in 1982. Sadly, Concord Naval Weapons Station exposed workers to asbestos, which is why today, many former employees struggle with awful, life-threatening diseases. Asbestos would be used on ships as insulation for boilers, hot pipes, incinerators, and steam pipes. It is important to note that 1 in 500 shipyard workers was in charge of insulating certain parts of the ship, which placed the individual at very serious risk of asbestos exposure.
