Hydrogen chloride (HCl) has a strong odor and is a colorless to somewhat yellow gas. It is employed in tanning leather, electroplating metals, pickling, cleaning, manufacturing, and refining a broad range of goods. Numerous polymers may also produce hydrogen chloride when burned. Hydrogen chloride is harmful because it may irritate the larynx, throat, eyes, nose, and skin.

Furthermore, exposure to liquid hydrogen chloride might result in frostbite. Workers can be harmed by hydrogen chloride toxicity. The level of harm is based on the duration, dosage, and task performed.
