Chlorine (Cl) is the chemical element with atomic number 17. The chloride ion, which is part of common salt (NaCl) and other compounds, is abundant in nature and necessary to most forms of life, including humans.
Chlorine is among the ten highest volume chemicals produced in the United States. At room temperature, it is yellow-green gas with a pungent, irritating odor similar to bleach. It is typically pressurized and cooled for storage and shipment as an amber-colored liquid. Chlorine does not combust easily but may combine with other common substances to form explosive compounds.
Chlorine has a variety of uses: to disinfect water as part of the waste water sanitation process for sewage and industrial waste; as a bleaching agent during the production of paper and cloth; in cleaning products, including household bleach; and in the preparation of chlorides, cleaning solvents, pesticides, polymers, synthetic rubbers, and refrigerants.
Because of its widespread use in industrial and commercial locations, exposure to chlorine gas or liquid can occur from an accidental spill or release, or from a deliberate terrorist attack. The most harmful route of exposure is from breathing chlorine gas. Exposure may also result from skin contact or eye contact with chlorine gas or by swallowing chlorine-contaminated food or water.
Health Effects of Chlorine Exposure
When chlorine enters the body as a result of breathing, swallowing, or skin contact, it reacts with water to produce acids. The acids are corrosive and damage cells in the body on contact. Most harmful chlorine exposures are the result of inhalation of chlorine. Health effects of chlorine typically begin within seconds to minutes. Common symptoms of chlorine exposure include: airway irritation, wheezing, difficulty breathing, sore throat, cough, chest tightness, eye and skin irritation
The severity of health effects from chlorine exposure depend upon the route of exposure, the dose, and the duration of exposure. Breathing high levels of chlorine causes fluid build-up in the lungs, a condition known as pulmonary edema, which may not be apparent until several hours after exposure.
Chlorine Gas Monitoring
When chlorine is used in the manufacture of plastics, textiles, pharmaceuticals or when used in waste water treatment plants or other areas where exposure to chlorine gas is possible, a monitoring and ventilation system should be in place.
For use in hazardous or classified locations, choose an explosion-proof smart gas monitor with electrochemical sensing. Smart chlorine gas monitors can help prevent high exposure to chlorine gas and keep personnel and others safe.
Production of industrial and consumer products
Chlorine is used in making plastics, solvents for dry cleaning and metal degreasing, textiles, agrochemicals and pharmaceuticals, insecticides, dyestuffs, household cleaning products, etc.
Purification and disinfection
Chlorine is an important chemical for water purification (used in water treatment plants), in disinfectants, and in bleach. Chlorine in water is more than three times as effective as a disinfectant against escherichiacoli (e. coli) than an equivalent concentration of bromine and is more than six times more effective than an equivalent concentration of iodine. In the form of hypochlorous acid, it kills bacteria and other microbes in drinking water supplies and public swimming pools. In most private swimming pools, sodium hypochlorite is used, formed from chlorine and sodium hydroxide, or solid tablets of chlorinated isocyanurates.
It is often impractical to store and use poisonous chlorine gas for water treatment, so alternative methods of adding chlorine are used. These include hypochlorite solutions, which gradually release chlorine into the water, and compounds like sodium dichloro-s-triazinetrione and trichloro-s-triazinetrione. When added in small amounts to water, the chlorine atoms hydrolyze from the rest of the molecule forming hypochlorous acid (HOCl), which acts as a general biocide, killing germs, micro-organisms, algae, and so on.
Other uses
Chlorine is used in the manufacture of numerous organic chlorine compounds.Those with the highest production volumes are 1,2-dichloroethane and vinyl chloride, intermediates in the production of PVC.
Other particularly important organo-chlorines are methyl chloride, methylene chloride, chloroform, vinylidene chloride, trichloroethylene, perchloroethylene, allyl chloride, epichlorohydrin, chlorobenzene, dichlorobenzenes, and trichlorobenzenes. Chlorine is also used in the production of chlorates and in bromine extraction.
