Monitoring Your Respirator

As you work, you must not only monitor the seal around your face, but you must also monitor how well your respirator is working.

You will know that your respirator is not working when:

- You can smell or taste the contaminant;
- Breathing becomes difficult;
- You become dizzy or sick feeling;
- The manufacturer's recommended service life   of the filters or cartridges expires; or
- The respirator is damaged.

WARNING: Never use or continue to use a respirator that is not working perfectly.
