Permeation of a straight oil metalworking fluid through a disposable and a chemically protective nitrile glove

Permeation of a straight oil metalworking fluid through disposable nitrile, chloroprene, vinyl, and latex gloves

“…The permeation procedure was based on a modified American Society for Testing and Materials (ASTM) F739-99a permeation method [10,[18][19][20]. Out-of-the-box gloves were conditioned for 24 h in a desiccator, where the relative humidity was maintained at 55 ± 1% by saturated aqueous sodium dichromate as recommended by the ASTM method.…”

“…The evaporation process to measure permeated D4 in hexane collection has been validated elsewhere, and the recovery was 99.6 ± 3.1% [10]. The recovery for perfluorohexane collection was 96.7 ± 0.4%.…”

“…Exposures to [2,12] and our research team has shown that MWF composition in the collection solvent can change relative to the original challenge [10,13]. The permeation of a straight oil MWF Deolene D4 through a disposable and a chemically protective nitrile glove has previously been studied using chromatographic and gravimetric methods [10].…”

“…Exposures to [2,12] and our research team has shown that MWF composition in the collection solvent can change relative to the original challenge [10,13]. The permeation of a straight oil MWF Deolene D4 through a disposable and a chemically protective nitrile glove has previously been studied using chromatographic and gravimetric methods [10]. The collection medium was hexane instead of water or air, because hexane immediately and adequately removed the permeated non-polar and non-volatile challenge from the inner surface of the gloves, and avoided underestimation of exposure to the challenge MWF through the glove.…”

The Effect of Protective Glove Exposure to Industrial Contaminants on Their Resistance to Mechanical Risks

“…As a result, large changes in mechanical behavior may occur even at a low swelling ratio [10]. In addition, the effect of oils and greases on polymer properties is generally not associated with a modification in surface coloration [16,17]. It must be noted that this difficulty of detection of a protection level degradation may induce a false feeling of safety for the user.…”
