• Description:
  Despite ongoing chemical protective clothing testing efforts, about 2.9 million workers still suffer from dermatitis each year in the United States. One critical gap in knowledge is the level of protection afforded by protective clothing under worker-use conditions. The aim of this study was to test the influence of hand movement on the permeation and penetration of captan through disposable nitrile gloves, and to test whether movement caused a change in glove properties. Testing was conducted using a previously described robotic hand test system exposed to an aqueous emulsion (217 mg/mL) of captan at 35 +/- 0.7 degrees C. The method blank was exposure to water alone. Tensile strength and elongation tests were also performed on the glove materials in accordance with ASTM methods 03187-00 and D412- 98a. With hand movement, the permeated mass of captan collected after 8 hr ranged from 1.6 to 970 microg (brand A) and 8.6 +/- 1.2 microg (brand B). Without hand movement, the corresponding masses were 1.4 to 8.4 microg (brand A) and 11 +/- 3 microg (brand B). These results were not significantly different at p ≤0.05 using parametric and nonparametric statistical tests but they indicated that hand movement could influence the precision of permeation (F-test p ≤0.05). One glove (brand C) exhibited catastrophic failure after 2 hr with movement (including the method blank), in comparison with 0.5 to 9.9 microg captan with no movement. No significant differences, at p ≤0.05, in tensile strength or elongation existed between the glove materials. Thus, the ASTM standard test methods were not good indicators of glove performance under worker-use conditions. Hand movement did not appear to significantly affect the permeation of captan through nitrile gloves. However, hand movement did influence degradation, resulting in catastrophic glove failures and signs of penetration. [Description provided by NIOSH]
