Chlorine (Cl2) Gas Detectors

Chlorine (Cl2) is used in many industries, including pharmaceutical, food and beverage, pulp and paper, electronics, and wastewater treatment. Specifically, chlorine is used in manufacturing plastics, pesticides, gasoline additives, brake fluid, and antifreeze. Oil refineries inject chlorine directly into stacks to reduce sulfur emissions. Proper chlorine gas detection is essential in locations where workers are likely to be exposed to toxic Cl2 gas, such as in storage tanks or near processing units.

Characteristics of Chlorine

Chlorine is greenish yellow gas with a characteristic pungent odor. Although not classified as an explosive gas, chlorine will react explosively or form an explosive compound when combined with substances like acetylene, ether, turpentine, ammonia, hydrogen, and fuel gas.

Chlorine derivatives are commonly used for their disinfectant properties. Chlorine is highly toxic. The toxins take their route through the lungs, irritating the respiratory tract. High doses of chlorine gas can cause death quickly.
