The following resources provide information about occupational exposure to hydrogen chloride. Visit NIOSH’s page on Managing Chemical Safety in the Workplace to learn more about controlling chemical workplace exposures. If you work in an industry that uses hydrogen chloride, please read chemical labels and the accompanying Safety Data Sheets for hazard information. NIOSH recommends that employers use the Hierarchy of Controls to prevent injuries. Steel and iron workers who work in plants that harden iron and steel.Factory workers in industries that manufacture acrylic fibers, synthetic rubber, and plastics.Agricultural workers who fumigate outdoor pests in areas such as fruit orchards.Workers who fumigate ships and buildings.
Hydrogen cyanide may be used in the workplace for fumigation, electroplating, mining, chemical synthesis, and the production of synthetic fibers, plastics, dyes, and pesticides. Some examples of workers at risk of being exposed to hydrogen cyanide include the following: The level of harm depends upon the dose, duration, and work being done. Exposure to liquid hydrogen chloride may cause frostbite. Workers may be harmed from exposure to hydrogen chloride.
Hydrogen chloride can irritate the skin, nose, eyes, throat, and larynx.

Steel pickling Hydrochloric acid is used in pickling operations for carbon, alloy, and stainless steels. The largest end uses for hydrochloric acid are steel pickling, oil well acidizing, food manufacturing, producing calcium chloride, and ore processing. Hydrogen chloride (HCl) is a colorless to slightly yellow gas with a pungent odor. Hydrochloric acid is an important and widely used chemical.
