||Chemical protective clothing and gloves are usually too expensive to be considered disposable. Their repeated use without effective decontamination may result in secondary exposure. However, decontamination may change the physical and chemical properties of the barrier material, causing variations in breakthrough time (BT) and steady-state permeation rate (SSPR). Neoprene, butyl rubber and nitrile rubber were selected for this study, while toluene and acetone were chosen as the challenge chemicals. Permeation was measured in a closed loop system using a 2.5cm permeation cell and an infrared analyser. Following the permeation test, the samples were thermally decontaminated. After each exposure and decontamination cycle, BT and SSPR were measured. Permeation test results were collected on each material/chemical combination for ten cycles. Findings with respect to changes in BT and SSPR as a function of glove material, solvent and number of cycles are discussed.
