Occupational exposure to hydrogen cyanide and cyanide salts (NaCN, KCN, and Ca(CN)2)
Filetype[PDF-2.95 MB]

  • Description:
    "Recommended criteria for a standard intended to protect the health of workers against exposure to hydrogen-cyanide (74908) and cyanide salts, especially sodium-cyanide (13998033), potassium-cyanide (151508) and calcium-cyanide (592018), for up to a 10-hour work shift, 40-hour work week, over a working lifetime. Occupational exposure to these compounds is defined as exposure to airborne concentrations greater than the corresponding action levels, or one- half the corresponding recommended ceiling environmental exposure limit. The main topics covered include: recommendations for levels of cyanide in the workplace air, including sampling and analysis; medical surveillance; personal protective equipment and clothing; informing employees of cyanide hazards; work practices and control procedures; sanitation, monitoring and recordkeeping; biologic effects of exposure, including epidemiology, carcinogenicity, mutagenicity, and teratogenicity; environmental data and engineering controls." - NIOSHTIC-2
