Industries that use inorganic arsenic and its compounds, where sampling may be necessary, include wood preservation, glass production, nonferrous metal alloys, and electronic semiconductor manufacturing. Inorganic arsenic is also found in coke oven emissions associated with the smelter industry. Arsenic and its compounds occur in crystalline, powder, amorphous, or vitreous forms. The following references provide information on evaluating occupational exposures to arsenic.
- OSHA Occupational Chemical Database. OSHA's premier one-stop shop for occupational chemical information. It compiles information from several government agencies and organizations. Information available on the pages includes chemical identification and physical properties, exposure limits, sampling information, and additional resources.
OSHA has developed and validated methods for use by the Salt Lake Technical Center (SLTC) laboratory. The following method has been adopted by many laboratories for the analysis of chemical compounds.
- Arsenic, Cadmium, Cobalt, Copper, Lead, and Nickel (Open Vessel Microwave Digestion/ICP-MS Analysis). Method 1006, (January 2005).
- Arsenic Backup Data Report, ID-105. Addendum to Method ID-105, (1991).
