Hydrogen chloride health effects

Ten young adult asthmatics showed no adverse respiratory health effects after multiple inhalation challenge with 0.8 and 1.8 ppm hydrogen chloride. ... 

Industrial poisoning. The production of silicone products uses substances harmful for human health. These are inorganic substances (ammonia, chlorine, sodium and potassium hydroxides, sulfuric and hydrochloric acids, hydrogen chloride) and organic compounds of various types, such as hydrocarbons (methane, benzene and its homologues), chlorine derivatives (methyl- and ethylchloride, chlorobenzene), alcohols (methyl, ethyl, n-butyl, hydrosite), acetone, pyridine, etc. The information about their toxicity, explosion hazard, effect on human body, as well as maximum allowable concentrations of gases and vapours in the air at workplace can be found in special references.(Ryabov 1970). A comprehensive description of silicone substances is given in Table 29. 

On the basis of its review of human and experimental animal health-effects and related data, the subcommittee concludes that the Navy s proposed SEAL 1 of 2.5 ppm for hydrogen chloride is too conservative. The subcommittee...

The subcommittee recommends that additional research be conducted on the health effects of mixtures of the irritant gases—ammonia, chlorine, hydrogen chloride, hydrogen sulfide, nitrogen dioxide, sulfur dioxide. The subcommittee also recommends additional studies be conducted on the combined effects of hydrogen cyanide, carbon monoxide, and hydrogen sulfide. 

Toxicity and health effects Exposure to hydrogen chloride causes irritation and corrosive effects to the tissue on contact. Acute exposure to low concentrations of hydrogen chloride causes throat irritation, and prolonged exposure... 

PVC and Health Effects Virgin PVC is thermally and photochemically unstable and has a tendency to loose hydrogen chloride easily when heated, hence a stabiliser (a tin or a lead compound, usually heavy metal based compounds) is commonly used in the final compound to improve the heat stability. Various additives that are used to reduce various... 

Health effects of PVC itself and its additives (mainly plasticisers) have been the subject of a very intense debate for many years, beginning from the danger of release or extraction of the heavy metal based stabilisers and health implications of phthalate plasticisers and other additives to the danger of formation of dioxins and hydrogen chloride gas during accidental fires . For many years, there has been a never ending debate between different parties about PVC and its effect on health and on the environment, some are...
