Rocky Mountain Ordnance Plant
Mustard Gas Production
(March 22, 1954)
Mustard gas production. 1950s production of artillery shells containing mustard gas at Rocky Mountain Arsenal, Commerce City, Colorado, USA. Mustard gas, a toxic chemical warfare agent, consists of chlorinated sulphur hydrocarbons. It causes severe blistering to the skin and can be fatal, hence the protection worn by the workers. These are 105-millimetre shells. This arsenal, used to produce a range of chemical weapons, was constructed during World War II. It was operated by the US Army until it closed in 1992. Photographed by a Denver Post photographer on 22 March 1954.
