Health hazard evaluation report No. HETA 81-164-982, Pacific Telephone Company, San Francisco, California
On February 9, 1981, the National Institute for Occupational Safety and Health (NIOSH) received a request for a Health Hazard Evaluation at the Pacific Telephone Company office at 215 Fremont Street, San Francisco, California. Concern was expressed over exposure to vehicle emissions from street traffic (carbon monoxide fumes) entering the intake ventilation system, and that the air conditioning unit did not work properly, resulting in overcooling or overheating and dry air. Air sampling was conducted on all four floors for carbon dioxide, nitrogen dioxide, and sulfur dioxide. Carbon dioxide concentrations were below the limit of detection, and no nitrogen dioxide or sulfur dioxide were detected. Peak carbon monoxide (CO) concentrations ranged from 2.5 to 4.0 ppm, well below the NIOSH-recommended criterion (200 ppm ceiling) and the 35 ppm, 8-hour time-weighted average.
