This pamphlet describes briefly the properties, uses and toxic effects of chlorine (7782505). Chlorine gas is acutely irritating to the mucous membranes; in the liquid state it will burn the skin; when mixed with certain other chemicals, it can form flammable or explosive mixtures. Chlorine can be detected by its smell, though continued exposure dulls this sense. Chlorine work areas should be well ventilated, and have emergency gas masks, showers, face- flooding and eye-washing sprays. Emergency treatment, and the responsibilities of workers and management are outlined.
