Arsine (arsenic hydride) poisoning In the workplace.
Am Ind Hyg Assoc J 1979 Oct; 40(10):A56-A61
The NIOSH current intelligence bulletin on occupational poisoning due to arsenic-hydride (7784421) (arsenic) is presented. Physiochemical properties and sources of exposure are summarized. Occupational standards and exposures are reviewed. The OSHA standard for arsine is 0.05 milligram per cubic meter (mg/m3) time weighted average. NIOSH recommends that arsine exposures be limited to 0.0002mg/m3 during any 15 minutes sampling period. NIOSH estimates that approximately 900,000 workers are exposed to identified sources of arsine. Since arsenic is a widespread element, unidentified exposures can occur in unsuspected work situations. Clinical signs and symptoms of acute and chronic arsine and chronic arsenic (7440382) poisoning are described. Examples of occupational exposures to arsine in smelting and refining operations and in enclosed spaces are given. The physiochemical and toxic properties of hydrogen-antimonide (7803523) (stibine) are summarized. NIOSH recommendations regarding arsine or stibine exposure are presented. These include reducing occupational exposures by appropriate work practices, providing workers with information on hazards associated with the compounds, and conducting additional research on the chronic and acute effects of arsine and stibine.
