User Seal Checks - 3M Ultimate FX Manual Del Usuario

6. No visible gaps between the face seal and the face.
7. Skin in front of ear is not wrinkled.
8. Nosecup does not obscure vision.
9. Ensure that other safety equipment does not interfere with buckles or fit of respirator.
If any of these criteria are not met, it is possible that the respirator may not fit you adequately. Selecting a different size facepiece may provide you
with a more adequate fit. More than one facepiece size may need to be donned before you determine the best size for your face. A fit test can confirm
adequate fit. If you have further questions, see your supervisor.

User Seal Checks

Always check the seal of the respirator on your face before entering a contaminated area according to the instructions provided below for your
specific respirator configuration. The positive pressure seal check is the primary and preferred method for verification of a good seal for all cartridge
and filter configurations. The positive pressure seal check is the only method for this respirator with Filters 2000 Series. The negative pressure user
seal check can also be done for additional verification of a good seal for this respirator with Cartridges 6000 Series and Filters 7093/7093C. Be
careful not to disturb the respirator seal by pressing too forcefully during negative pressure seal checks.
IMPORTANT: If you cannot achieve a proper seal, DO NOT enter the contaminated area. See your supervisor. Before assigning any respirator
to be worn in a contaminated area, a qualitative or quantitative fit test MUST be performed per OSHA Standard 1910.134, CSA Standard
Z94.4 or Brazil Respiratory Protection Program of the Ministry of Labor.
Positive Pressure User Seal Check for all approved configurations and required for Filters 2000
Series
1. Remove the exhalation valve cover by depressing bottom of cover with thumb and sliding cover up, parallel with lens.
2. Place the palm of your hand over the exhalation valve and exhale gently (Fig. 15). Care must be taken to ensure a good seal of the exhalation valve. To
do this, cover the entire face of the blue valve with the base of the palm.
3. If the facepiece bulges slightly and no air leaks are detected between the face and the facepiece, a proper seal has been obtained.
4. If faceseal air leakage is detected, reposition the respirator on your face and/or readjust the tension of the straps to eliminate leakage and
recheck seal.
5. Replace exhalation valve cover by placing open end at top of exhalation valve assembly, guide tabs underneath valve cover assembly and slide
downward until the valve cover snaps in place.
If faceseal air leakage is detected, reposition the respirator on your face and/or readjust the tension of the straps to eliminate the leakage and recheck
seal. Care must be taken when performing the positive pressure seal check not to exhale too hard. The aim is to check the seal, not disturb the seal
between the mask and the face.
Negative Pressure User Seal Check with Cartridges 6000 Series
1. Place palms of hands to cover face of cartridge or open area of 3M™ Filter Retainer 501and inhale gently. If you feel the facepiece collapse slightly
and pull closer to your face with no leaks between the face and facepiece, a proper seal has been obtained (Fig. 16).
2. If faceseal air leakage is detected, reposition the respirator on your face and/or readjust the tension of the straps to eliminate leakage and
recheck seal.
Be careful not to disturb the respirator seal by pressing too forcefully during negative pressure seal checks.
NOTE: Use of filter retainer 501 may aid respirator wearer in conducting a negative pressure user seal check.
Negative Pressure User Seal Check with Filters 7093/7093C
1. Using hands squeeze or press filter covers toward facepiece and inhale gently. If you feel the facepiece collapse slightly and pull closer to your face
with no leaks between the face and facepiece a proper seal has been obtained (Fig. 17).
2. If faceseal air leakage is detected, reposition the respirator on your face and/or readjust the tension of the straps to eliminate the leakage and recheck
seal.
Be careful not to disturb the respirator seal by pressing too forcefully during negative pressure seal checks.
Negative Pressure User Seal Check with Dual Airline
1. Disconnect airline hose from air control valve.
2. With breathing tube still connected to the air control valve inhale gently. If you feel facepiece collapse slightly and pull closer to your face with no leaks
between the face and facepiece, a proper seal has been obtained.
