Chlorine is a greenish yellow gas with a pungent suffocating odor. Chlorine is a diatomic gas that is a member of the halogen family of elements. It is a powerful oxidizing compound that has many industial uses. Chlorine is used in manufacturing, as a reagent in synthetic chemistry, for water purification, bleaching of wood pulp and in the production of chlorinated lime, which is used in fabric bleaching. Chlorine is also widely used in plastics production.
Chlorine solutions are commonly used in household cleaners and disinfectants. Chlorine gas is a potent irritant to the eyes, the upper respiratory tract, and lungs.
Chlorine is highly toxic and proper safeguards, including gas monitoring, are deemed critical to industrial health and safety programs.
