Follow these steps to lower the facepiece from the in-use position on the face to the drop-down position below the chin.
1. Grasp the bottom of the quick latch, at chin level, with the thumb and first two fingers (Fig. 18).
2. Pull up and open the quick latch, as the respirator loosens from the face and begins to slide to the drop-down position (Fig. 19). Facepiece will rest
below the chin (Fig. 20).
Follow these steps to raise the facepiece from the drop-down position below the chin to the
in-use position on the face.
1. Grasp the front of the facepiece with the thumb at the bottom of the facepiece and the first two fingers at the top of the opened quick latch (Fig. 21).
2. Place the facepiece over the mouth and nose (Fig. 22).
3. Push the quick latch down and click into the lower, closed position (Fig. 23).
RESPIRATOR REMOVAL
1. Grasp the bottom straps, at the back of the neck and unhook them.
2. Remove respirator by pulling head harness down from over head. (These two steps can be done in reverse order if preferred.)
FIT TESTING
The effectiveness of a respirator will be reduced if it is not fitted properly. Therefore, either qualitative or quantitative fit testing must be conducted
prior to the respirator being used. Fit testing is a U.S. Occupational Safety and Health Administration (OSHA), a Canadian CSA and a Brazilian
BMOL requirement. Respirators should also be fit tested while wearing any personal protective equipment (PPE) the wearer may use in their work
environment that may affect the fit of the respirator (e.g. hoods, hardhats, hearing protectors, etc.). For further information concerning fit testing,
contact 3M Technical Service.
• Quantitative Fit Testing: Quantitative Fit Testing (QNFT) can be conducted using a 3M™ Fit Test Adapter 601 and P100 filters such as the 3M™
Particulate Filters 2091 or 7093.
• Qualitative Fit Testing: Qualitative Fit Testing (QLFT) with the 3M™ Qualitative Fit Test Apparatus FT-10 or FT-30 can be conducted using any of
the NIOSH approved Particulate filters.
Entering and Exiting a Contaminated Area
• Airborne contaminants which can be dangerous to your health include those that are so small you may not be able to see or smell them.
• Always conduct a user seal check before entering a contaminated area.
• Leave the contaminated area immediately if any of the following conditions occur:
Any part of the respirator becomes damaged.
°
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 the concentrations of contaminants may have reached levels at which this respirator may no longer provide adequate protection.
°
• Do not wear this respirator in 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.
