Hydrogen Chloride (HCl) Gas Detectors
Most hydrogen chloride (HCl) is used in the production of hydrochloric acid. It is also an important reagent in other industrial chemical transformations, such as the hydrochlorination of rubber and the production of vinyl and alkyl chlorides. Other industries or applications where high levels of hydrogen chloride may occur include petrochemical facilities, cotton production, metal pickling, rubber manufacturing, and semiconductor production.

Characteristics of Hydrogen Chloride
Hydrogen Chloride is a colorless to slightly yellow corrosive gas with a pungent, irritating odor. Although not considered a combustible gas, it may react or form combustible compounds when contact is made with alcohol and hydrogen cyanide or with aluminum-titanium alloys. Dissolving Hydrogen chloride in water will yield a strong highly corrosive acid. It is for this reason that HCl is a strong irritant to the eyes, nose, and upper respiratory tract. Levels of 35 ppm can cause irritation to the throat even after a very short period of time.
