Abstract
Local 111 of the International Brotherhood of Electrical Workers requested an evaluation of fly-ash, silica, and arsenic exposures to workers who repair electrostatic precipitators at the Public Service Company of Colorado (SIC-4911), Pueblo, Colorado. On July 18 and 19, 1981, all eight workers were monitored for crystalline silica, total dust particulates, arsenic (7440382), lead (7439921), selenium (7782492), and cadmium (7440439). Most respirable and total particulate breathing zone air samples exceeded the OSHA standards of 10 milligrams per cubic meter (millig/m3). Arsenic concentrations peaked at 0.01millig/m3, above the evaluation criteria of 0.002millig/m3. One sample for silica exceeded the evaluation criteria of 0.05 milligrams per cubic meter. Three workers reported they had skin problems due to fly-ash. One worker had a significant loss of pulmonary function. The authors conclude that a potential health hazard exists from over exposure to particulates, arsenic, and crystalline silica. The exposure to fly- ash during cleanout does not appear to have resulted in pulmonary disease. They recommend shower facilities, a respiratory program, shaving so that respirators will fit properly, and yearly physical examinations.
