Title Identifying Occupational Exposure Risks to Hydrogen Cyanide and Other Industrial Chemicals
Introduction EMSL Analytical provides environmental and industrial hygiene testing services, sampling supplies and monitoring instruments to identify potential chemical exposure hazards in the workplace.

Cinnaminson, New Jersey, November 10th, 2021

The National Institute for Occupational Safety and Health (NIOSH) describes hydrogen cyanide (HCN) as a colorless or pale-blue liquid or gas with a bitter, almond-like odor. It is a liquid below 78°F (25.6°C) and a gas above 78°F.

Hydrogen cyanide is produced on an industrial scale for use in many industries. It is used commercially for fumigation, electroplating, mining, chemical synthesis, and the production of synthetic fibers, plastics, dyes and pesticides. It has even been used as a chemical warfare agent in the past and has the military designation of AC. Not surprisingly, NIOSH reports that exposure to hydrogen cyanide can be fatal. Exposure can interfere with the body’s use of oxygen and may cause harm to the brain, heart, blood vessels and lungs. As such, workers may be harmed from exposure with the level of exposure depending upon factors such as the dose, duration and work being done.

Some examples of workers at risk of being exposed to hydrogen cyanide according to NIOSH include:

  • Workers who commercially fumigate ships and buildings
  • Agricultural workers who fumigate outdoor pests in areas such as fruit orchards
  • Factory workers in industries that manufacture acrylic fibers, synthetic rubber and plastics
  • Steel and iron workers who work in plants that harden iron and steel


“Routes of potential exposure include ingestion, inhalation, skin contact and eye contact,” said Joe Frasca, Senior Vice President of Marketing at EMSL Analytical, Inc. “To protect workers, the Occupational Safety and Health Administration (OSHA) has set a Permissible Exposure Limit (PEL) for hydrogen cyanide and NIOSH has a Recommended Exposure Limit (REL). To help in these efforts, EMSL’s industrial hygiene laboratories offer testing services, sampling supplies and monitoring instruments to identify hydrogen cyanide and many other industrial chemicals.”

EMSL also recently sponsored an educational video about hydrogen cyanide and potential occupational exposure risks that can be seen at: https://youtu.be/ijFzrQKZEws
