A respirator cartridge change schedule outlines how often cartridges should be replaced and what information was relied upon to make this judgment. A cartridge's useful service life varies based on many factors, and once exceeded, no longer provides adequate protection. Despite regulatory requirements to develop a respirator cartridge change schedule, some users may rely on taste, smell, or irritation of gases or vapors coming through the cartridge.

The webinar explains how gas/vapor cartridges work and different methods of estimating cartridge service life and will help you develop a respirator cartridge change schedule so you can prevent potential exposures and meet regulatory requirements.

Learning Outcomes

Upon completion, participants will be able to:

  • Estimate respirator cartridge service life based upon workplace conditions and worker activities.
  • Develop cartridge change schedules that comply with applicable local regulations.
  • Implement cartridge change schedules that are easy for workers to remember.
  • Limit cartridge reuse based on potential migration of organic vapors during storage.
