The purpose of this study was to develop methodology involving the use of biological monitoring of exhaled air to determine respirator protection factors. The concentration of fluorocarbon 113 in breath was correlated to the original exposure concentration while wearing a full facepiece negative pressure respirator. Protection factors calculated from breath sampling were compared to fit factors derived from a negative pressure test device. Although biological monitoring indicated a nearly three fold increase in fluorocarbon 113 penetration rates compared to the negative pressure fit test results, a correlation of 0.86 suggests that this methodology may be used in the design of a workplace protection study. No correlation was found between the biological and quantitative mask sampling methods.Type
