Preliminary evaluation of a prototype organic vapor respirator end of service life indicator.

• Description:
  Prototype end of service life indicator devices were evaluated on a respirator cartridge test system. The detector system for the prototype devices was based on a metal oxide combustible gas sensor. The duty cycle in the prototype and the effects of humidity on the sensor could allow exposure of the user to vapor concentrations greater than recommended ones. The author suggests that refinements in battery pack and reduction in sensor power consumption would eliminate the need for a duty cycle and ameliorate sensor stability problems. He recommends that provisions be made so that the sensor remains activated even during charging to help stabilize sensor response. A humidity compensation circuit or the maintenance of a constant humidity environment for the sensor also are recommended. [Description provided by NIOSH]
