Permeation tests were performed on several protective clothing materials with a nitroglycerin and ethylene glycol dinitrate-based explosive. In order to perform permeation tests, a modified version of the F-739 permeation cell was used. Breakthrough times showed that the most resistant material was nitrile. In contrast, it was proven that cotton gloves, presently used in the explosives industry to protect workers from contact with dynamite, are the worst barrier. Decontamination of nitrile by washing was evaluated and it was proven to be inadequate. Heat was tried as a decontamination procedure but it requires high temperature and produces degradation of nitrile.
