Chlorine dioxide is a yellow to reddish-yellow gas with a pungent, sharp odor similar to that of chlorine and ozone. As one of several oxides of chlorine, it is a potent and useful oxidizing agent used in several industrial processes.
Chlorine dioxide is used in bleaching wood pulp (Kraft process), disinfection and treatment of water supplies and fumigant treatment in food processing.
Chlorine dioxide acts as a severe respiratory and eye irritant in humans.
Chlorine dioxide is highly toxic and proper safeguards, including gas monitoring, are deemed critical to industrial health and safety programs.
