Abstract
This information profile on hydrogen-chloride (7647010) lists its chemical structure, Chemical Abstracts Service number, Registry of Toxic Effects of Chemical Substances number, production figures and economic trends in production, uses, number of companies producing and using hydrogen-chloride, and the biological effects of exposure. Hydrogen-chloride is irritating in all concentrations to eyes and mucous membranes, with pathological changes occurring in bronchial and tracheal epithelium. Alveolar epithelial changes and vascular injury also occur. Liver injury has been noted in many instances. Acute, subchronic, and chronic effects of exposure are discussed. Chronic exposure in the industrial situation commonly causes tooth decay, bleeding of gums and nose, ulcers of oral and nasal mucosa and sensitive skin. The threshold limit value is recommended to be 5ppm, which is not great enough to be toxic, but is marginal for extreme irritation. Other standards are cited. Hydrogen-chloride gas is used primarily to make hydrochloric-acid. (Contract No. 210- 77-0120)
