Abstract
A prototype end of service-life indicator for organic vapor air purifying respirators was developed and tested under laboratory conditions. A metal oxide gas sensor (MOGS) was incorporated in the unit. The detector and indicator light are designed to fit on the face mask of a chemical cartridge respirator, and the associated electronics and power supply are placed in a pack suitable for belt mounting. The device was used with existing respirators, gave a positive alarm of contaminant breakthrough, and detected a wide variety of organic vapors. The authors recommend field testing and exploration of other detectors such as piezoelectric ones.
