Abstract
Worker exposures to airborne contaminants and noise were surveyed on August 25 and 26, 1979 at the United States Border Crossing Stations (SIC-4784) in El Paso, Texas. The evaluation was requested by the United States Department of Agriculture, Animal and Plant Health Inspection Service, on behalf of an unspecified number of inspectors. Noise levels and airborne contaminant concentrations were measured. Preshift and postshift carboxyhemoglobin (COHb) values also were determined. Concentrations of carbon-monoxide (630080) (CO) sometimes equalled the OSHA standard of 50 parts per million (ppm). Concentrations of lead (7439921), ozone (10028156), benzene (71432), sulfuric-acid (7664939), particulates, sulfur- dioxide (7446095), and nitrogen-dioxide (10102440) were below respective OSHA standards of 0.05 milligram per cubic meter (mg/cum), 0.1ppm, 32mg/cum ceiling concentration, 10mg/cum, 10mg/cum, 5ppm, and 5ppm ceiling concentration. Noise levels were below the OSHA standard of 90 decibels relative to the A-weighted scale. COHb values increased during the work shift. The authors conclude that a CO hazard exists at these stations. Recommendations are included for maintenance of heating and air conditioning equipment, increasing the distance between vehicles awaiting inspection and the inspection booth, and job rotation periods of 30 minutes.
