3.  Do not use these respirators for respiratory protection during abrasive 

blasting or clean up.

contaminant exceeds maximum use concentration for this type of respirator 
as established by regulatory standards.

5. Leave area immediately if:
• Breathing becomes difficult
• Dizziness or other distress occurs
• You taste or smell the contaminant
• Unit becomes damaged
• Battery alarm activates
• Low Flow alarm activates
6.  This apparatus must not be worn with the blower unit switched off. If the
