Health Hazard Evaluation Report HETA 84-466 and HETA 85-017-1640, Federal Aviation Administration Facilities: Philadelphia, Pennsylvania; Westbury, New York

摘要

Environmental and breathing zone samples were analyzed for carbon-monoxide (630080), carbon-dioxide (124389), ozone (10028156), formaldehyde (50000), and organic solvents at the Philadelphia Airport Control Tower, Philadelphia, Pennsylvania, and the New York Terminal Radar Approach Control, Westbury, New York in October to November 1984, and March, 1985. The evaluation was requested by the Federal Aviation Administration because of employee complaints of eye irritation and respiratory problems. The ventilation systems at both facilities were evaluated. An unspecified number of employees were interviewed. At the Philadelphia facility, carbon-dioxide exposures of up to 1,100 parts per million (ppm) were measured. A carbon-dioxide concentration of 1,000ppm or more was considered indicative of inadequate outside air supply. All other exposures were well below their relevant standards or non detectable. Eye, skin, throat, and respiratory irritation were the most commonly reported symptoms. Problems in the design of the ventilation systems such as no outside air utilization during periods of extreme temperature and intakes and exhausts being located in the same area were noted. The authors conclude that a health hazard does not exist at either facility. The complaints probably stem from the ventilation systems. Recommendations include modifying and repairing the ventilation systems.
