In response to an employee request, an investigation was begun into aircraft ground crew exposures to diesel and gasoline engine exhaust at Southwest Airlines (SIC-4512), at Houston Hobby Airport, Houston, Texas. Complaints centered around emissions from fuel trucks and belt loaders. All diesel equipment at the site used JP4 fuel rather than diesel as it was readily available. No emissions control equipment was used on any gasoline or diesel equipment. Employees suffered transient eye and throat irritation. Samples were taken for elemental carbon (7440440) (Ce), carbon-monoxide (630080) (CO), and nitrogen-dioxide (10102440) (NO2). A ramp agent experienced the highest exposure concentration of Ce, 14.8 micrograms/cubic meter, while an area sample in the jetway area showed the lowest, 1.8 micrograms/cubic meter. Personal breathing zone exposures to diesel exhaust were similar to other studies of truck drivers. Full shift personal sample results for CO ranged from 3 to 7 parts per million (ppm). The highest instantaneous peak concentrations were 91 and 111ppm, still under the NIOSH ceiling limit of 200ppm. No sample gave detectable amounts of NO2. The author concludes that a health hazard from exposures to CO or NO2 was not found at the time of the survey. The author recommends that efforts be made to control exposures to a greater extent.
