- Abstract
- Hydrogen chloride (HCl) is a relatively common fire gas toxicant about which there has been much speculation and controversy. It is formed from the combustion of chlorine-containing materials, the most notable of which is polyvinyl chloride (PVC). Hydrogen chloride is both a potent sensory irritant and also a pulmonary irritant. It is a strong acid, being corrosive to sensitive tissue such as the eyes. Assessment of the toxicity of HCl in humans is made particulary difficult due to the lack of a suitable animal model for its variety of toxicological responses. In spite of these difficulties, a clearer picture of the role of HCl in the toxicity of smoke is gradually being developed.
