Industrial Hygiene Sampling Survey Report of Photon Power, Inc., El Paso, Texas.
NIOSH 1979 Jun:34 pages
Worker exposures to cadmium (7440439), tin (7440315), lead (7439921), toluene (108883) and thiourea (62566) were surveyed at Photon Power, Incorporated (SIC-3674) in El Paso, Texas, from March 13 to 15, 1979, as part of health research studies in photovoltaic solar energy conversion to direct electrical current. A walk through survey had been conducted at this facility on October 31, 1978. The company had 25 production operators. New employees were given physical examinations which included baseline blood cadmium and lead tests. There was no industrial hygienist. The factory manager was the safety and health supervisor. Personal and area air samples were collected and analyzed. Concentrations of cadmium, thiourea, tin and lead ranged from 4.4 to 821, 3.0 to 44.5, 0.5 to 45.3 and 5.0 to 17.1 micrograms per cubic meter, respectively. Toluene concentration was 21 milligrams per cubic meter. Methyl- alcohol (67561) concentrations ranged from 2.5 to 9.3 parts per million. The OSHA standard for cadmium fume was 100 micrograms per cubic meter and was exceeded only once when there was an exposure of 821 micrograms per cubic meter. Other concentrations were below the OSHA standards. There was a potential hazard from ultraviolet radiation during cell subdivision. The authors recommend a review of clean up procedures to reduce cadmium exposures and a study of ultraviolet radiation shielding.
