Hydrogen chloride usually exists as aqueous solutions and they are inflammable. Each listed percentage volume represents 100% of the Lower Explosive Limit for that gas or vapour, that is the point at which the gas is just capable of ignition.So flammable gas detectors must be calibrated to be best response for the flammable gas hazard in question and must measure in the region from no gas (zero) to the point the gas is just flammable, or 100% LEL. At room temperature, it is a colorless gas, which forms white fumes of hydrochloric acid upon contact with atmospheric humidity. Hydrogen chloride has not been found to be carcinogenic or to show reproductive or developmental toxicity in humans. The reaction of chlorine and hydrogen can be initiated by direct sunlight, other sources of ultraviolet light, static electricity, or sharp impact (See CI Pamphlet 121). Reacts rapidly and exothermically with bases of all kinds (including amines and amides). Although it is not flammable, it can be corrosive to the skin and eyes. Synthesis is relatively simple, but entails risk with flammable and corrosive chemicals, particularly the solvents used in extraction and purification; therefore, illicit production is often discovered by fires and explosions caused by the improper.
