Field tests of a permeation-type personal monitor for vinyl chloride

A passive dosimeter-type personal monitor for vinyl chloride has undergone extensive field testing. Collaborative studies by a number of laboratories confirm the accuracy, reliability, convenience and general acceptability of personal monitors utilizing gas permeation for sample collection and quantification. Data are generated as timeweighted averages and response is linear from 5 ppb to 50 ppm. The monitors which weigh only 35 g are unaffected by variations in environmental conditions.
