Abstract Details

2007, MS, University of Cincinnati, Medicine : Industrial Hygiene (Environmental Health).
Air monitoring was performed on an aircraft deicing fluid collection system at the Cincinnati/Northern Kentucky International Airport (CNKIA). The goal of the study was to determine employee exposure to ethylene glycol and the target compounds of decomposition as maintenance was performed on the system. The maintenance work involved performing confined space entries to repair and maintain various diversion chambers, pump stations and storage tanks used to collect and convey spent aircraft deicing fluid. The collected deicing fluid during the period of the study was primarily ethylene glycol based. The study included low flow area air sampling of selected diversion valve pits, pump stations and storage tanks for the presence of ethylene glycol as well as ethanol, formaldehyde, and acetaldehyde which are suspected end products of decomposition of ethylene glycol. The study also included the collection of weekly samples using Draeger Tubes to test for ethylene glycol. Samples were collected in the spring, summer and winter months. The results of the study revealed that the target compounds of decomposition were detected in various concentrations throughout the sample study. All results for the decomposition compounds were well below established regulatory and recommended levels. The weekly analysis for ethylene glycol revealed the potential for exposure to ethylene glycol at the diversion valves and to a lesser extent at the deicing pad pump stations during periods of heavy deicing. Ceiling limits for ethylene glycol at deicing fluid collection valves appear to be exceeded during periods of deicing fluid use greater than 750 gallons per day.
