Abstract

The National Institute for Occupational Safety and Health (NIOSH) recommends that appropriate workpractices be implemented to reduce the risk of worker exposure to arsine (AsH3) gas. There is a high potential for the generation of arsine gas when inorganic arsenic is exposed to nascent (freshly formed) hydrogen. This recommendation is based on several reports of worker exposure to arsine resulting in severe toxic effects or death. Most of the reported cases occurred when arsine was accidently generated during an industrial process. NIOSH would like to inform the occupational health community of some of the circumstances in which workers have been poisoned by arsine, with particular emphasis on the underlying mechanisms of generating the gas. We request that producers and distributors of arsenic and materials containing arsenic transmit information to their customers and employees, and that professional associations and unions inform their members. Stibine (SbH3), another toxic gas, if formed when antimony is exposed to nascent hydrogen. In most situations where arsine can be formed if antimony is present. Therefore, similar work practices should be implemented to reduce the risk of worker exposure to stibine.
