Gore tested the long-standing theory that rubber decontaminates better than leather. The results were surprising: leather samples were found to retain less residual chemical contamination than rubber samples following decontamination procedures. The tests were conducted using a FEMA testing protocol, which focused on chemicals that firefighters are likely to encounter in the field, including carbon disulfide (CS2), tetrachloroethylene, isooctane (gasoline), acrylonitrile, dimethyl formamide (DMF), and diethyl amine.
