dangerous to life or health (IDLH).
This term is defined in 29CFR 1910.134 (b).
3. Do not use these respirators for respiratory protection during
abrasive blasting or clean up.
4. Do not use in circumstances where the airborne concentration level
of 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 blower is switched off, a rapid build-up of carbon dioxide and
depletion of oxygen may occur, which could result in death or
serious injury.
