Abstract

An evaluation of glove materials against three different binary chemical mixtures selected from common industrial solvents was conducted. Changes in breakthrough time and permeation rate of the mixture components were evaluated as a function of the mixture composition. An increase in employee risk resulting from early mixture breakthrough time and enhanced mixture permeation rate over that of the pure chemicals was demonstrated. The permeation of a binary mixture through chemical protective clothing could not be predicted by the permeation results of the pure components. It is recommended that chemical protective clothing be tested for its permeation characteristics with the use of the chemical mixtures and conditions that reflect the work site exposure.

摘要

对选自常见工业溶剂的三种不同二元化学混合物的手套材料进行了评估。评估了混合物组分的穿透时间和渗透速率随混合物组成的变化。结果表明，与纯化学品相比，混合物更早的穿透时间和更高的渗透速率会增加员工风险。二元混合物透过化学防护服的渗透情况无法根据纯组分的渗透结果预测。建议使用反映工作场所暴露情况的化学混合物和条件，对化学防护服的渗透特性进行测试。
