Useful:

• Chemical Classes: Toxic Gases & Vapors -> Acids, Inorganic
• Canonical SMILES: Cl
• Recent ClinicalTrials: Hydrochloric Acid Lock Therapy in Children With Cancer
• Recent EU Clinical Trials: Metformin treatment of minimal hepatic encephalopathy in patients with liver cirrhosis
• Recent NIPH Clinical Trials: Clinical study about in vitro - in vivo correlation in supersaturation of poorly soluble basic drug
• Inhalation Risk: A harmful concentration of this gas in the air will be reached very quickly on loss of containment.
• Effects of Short Term Exposure: Rapid evaporation of the liquid may cause frostbite. The substance is corrosive to the eyes, skin and respiratory tract. Inhalation of this gas may cause asthma-like reactions (RADS). Exposure could cause asphyxiation due to swelling in the throat. Inhalation of high concentrations may cause lung oedema, but only after initial corrosive effects on the eyes and the upper respiratory tract have become manifest. Inhalation of high concentrations may cause pneumonitis.
• Effects of Long Term Exposure: Repeated or prolonged inhalation may cause effects on the teeth. This may result in tooth erosion. The substance may have effects on the upper respiratory tract and lungs. This may result in chronic inflammation of the respiratory tract and reduced lung function . Mists of this strong inorganic acid are carcinogenic to humans.
