Hydrogen Chloride is used in many industrial processes such as the tanning of leather products and to make the dyes and pigments for paint.
Exposure mainly occurs in in an industrial setting through accidental releases.
Hydrogen chloride gas reacts with moisture to create hydrochloric acid which is highly corrosive when it comes into contact with tissue such as the eyes, skin, nose and throat.
Higher concentrations of exposure cause rapid breathing difficulties leading to respiratory failure.
|0.1 – 9 ppm||No organic damage or change in respiratory pattern|
|10 ppm||Mild irritation to nose and throat|
|15-40 ppm||Immediate throat irritation|
|50 - 100 ppm||Barely tolerable – severe irritation to eyes skin and throat|
|1000 - 2000 ppm||Immediately dangerous; chest tightness, fever and confusion|
|1000 ppm||Lethal after a few minutes|
|Health||3||Can cause serious or permanent injury.|
|Flammability||0||Will not burn under typical fire conditions.|
|Instability||1||Normally stable but can become unstable at elevated temperatures and pressures.|
