Test and Evaluation for Chemical Resistance of Gloves Worn for Protection against Exposure to H-70 Hydrazine

摘要

Commercially available protective gloves were tested for chemical resistance to H-70 hydrazine and subjectively evaluated for dexterity/flexibility. The gloves were considered as alternatives to the bulky rocket fuel handler gloves used in maintenance and support of the F-16 Emergency Power Unit. A number of gloves (Edmont-Wilson 37-165; Surety 10-136R, 10-156R, and 10-166R; and Norton NSN: 8415-00-753-6550 through 6555) showed no detectable permeation of H-70 over a 6-hr exposure at 20 C and were found suitable for one-time use during spill clean-up operations. These same gloves are considered adequate for repeated use during routine maintenance tasks; however, if liquid H-70 contact is observed, the gloves should not be reused. Gloves should be decontaminated with 5% bleach before disposal. This report lists a second group of gloves that performed only a little less satisfactorily and could be used in emergency situations. The second group includes the readily available and federal stock-listed aircrew gloves by Norton and Edmont-Wilson. Gloves are mentioned by manufacturer and model number rather than by material, thickness, and other more objective parameters because of observed discrepancies between glove specifications and test results.
