The permeation by liquefied coal of gloves used in coal liquefaction pilot plants
The protective capabilities of PVC, natural rubber and milled nitrile rubber gloves currently used in coal liquefaction pilot plants were assessed, and the effectiveness of a laundering method was evaluated. The breakthrough times and cumulative permeation for exposure to toluene and to liquefied coal were determined by measurement of radiolabelled phenol tracer in the aqueous receiving medium. Breakthrough times agreed with the findings of other studies on exposure to liquefied coal, the nitrile laboratory glove resisted breakthrough the longest (12-14 h), although it was the thinnest material tested. Breakthrough times for the other gloves ranged from 2.75 to 6.5 h. Normalised for thickness, both PVC materials tested were more resistant to breakthrough than rubber. The laundering method did not completely decontaminate samples of PVC glove material pre-exposed to liquefied coal for 24 h under laboratory conditions.
