LIST OF WARNINGS AND CAUTIONS WITHIN THESE USER INSTRUCTIONS
This respirator system helps reduce exposures to certain airborne contaminants. Before use, the wearer must read and understand these User
Instructions. Follow all local regulations. In the U.S., a written respiratory protection program must be implemented meeting all the requirements
of 29CFR1910.134, including training, fit testing and medical evaluation. In Canada, CSA standard Z94.4 requirements must be met and/or
requirements of the applicable jurisdiction, as appropriate. Misuse may result in sickness or death. For correct use, consult supervisor and User
Instructions, or call 3M Technical Service in USA at 1-800-243-4630 and in Canada at 1-800-267-4414.
Contaminants that are dangerous to your health include those that you may not be able to see or smell. Leave the contaminated area immediately if
any of the following conditions occur:
– Any part of the system becomes damaged.
– Airflow into the respirator decreases or stops.
– Breathing becomes difficult.
– You feel dizzy or your vision is impaired.
– You taste or smell contaminants.
– Your face, eyes, nose or mouth become(s) irritated.
– You suspect that the concentration of contaminants may have reached levels at which this respirator may no longer provide adequate
protection.
Failure to follow these User Instructions may reduce respirator performance, overexpose you to contaminants, and may result in sickness or
death.
• To help maintain a good seal between the face and the faceseal, the respirator faceseal must be clear of obstructions at all times. Do not use
with beards or facial hair that prevent direct contact between the face and the respirator faceseal. Do not use with corrective eyeglasses. If
corrective eyeglasses are required, a 3M™ Spectacle Kit must be used inside the respirator.
• Do not enter a contaminated area until the respirator system has been properly donned. Do not remove the respirator before leaving the
contaminated area.

LIMITATIONS OF USE

Do not wear this respirator system to enter areas where:
• Atmospheres are oxygen deficient.
• Contaminant concentrations are unknown.
• Contaminant concentrations are Immediately Dangerous to Life or Health (IDLH).
• Contaminant concentrations exceed the maximum use concentration (MUC) determined using the Assigned Protection Factor (APF) for the specific
respirator system or the APF mandated by specific government standards, whichever is lower.
