• Description:
  The impact of glove flexure on permeation by solvents was investigated. Neoprene gloves were tested with acetone (67641) and polyvinylchloride (PVC) gloves were tested with heptane (142825). The test cell consisted of a 1 gallon wide mouth jar containing 2 liters of the solvent. The subject's hand was layered with four gloves: the test glove, a woven mesh glove, a Silvershield glove, and a surgical glove. The gloves were tested during no flexing, and flexing periods of up to 2 hours. By examining a graph of weight versus time, the breakthrough detection time (BT) and steady state permeation rate (SSPR) were determined. For the PVC/heptane combination, the SSPRs ranged from 74 to 118 micrograms per minute per square centimeter (microg/min/cm2) for the static test and from 147 to 162microg/min/cm2 for a 5 minute (min) flex, and equaled 133microg/min/cm2 for a 1min flex. The BTs for the PVC/heptane combination ranged from 9 to 13min for the static test, from 5 to 8min for the 1min flex, and from 6 to 7min for the 5min flex. For the neoprene/acetone combination, the SSPRs ranged from 110 to 130microg/min/cm2 for the static test and from 151 to 171microg/min/cm2 for both the 1min and 5min flexes. The BTs for the neoprene/acetone combination ranged from 55 to 60min for the static test, from 43 to 46min for the 1min flex, and from 41 to 49min for the 5min flex. Although significant differences in BT and SSPR were detected between the static and flex runs of both combinations, no significant differences were observed between the 1min and 5min flex runs of either combination. The authors conclude that glove flexure may affect glove permeation. [Description provided by NIOSH]
