19.5% oxygen.

2. Do not use when concentrations of contaminants are

immediately dangerous to life or health. 

3. Do not use these respirators for respiratory

protection during abrasive blasting.

4. Do not use in circumstances where the airborne

concentration level of contaminant exceeds maximum
use concentration for this type of respirator as

• Dizziness or other distress occurs
• You taste or smell the contaminant
• Unit becomes damaged
• Battery alarm sounds
