User Seal Checks - 3M 6500 Serie Instrucciones De Uso

Donning Respirator
1. Adjust head cradle size as needed to fit comfortably on head.
2. Place the respirator over the mouth and nose with one hand.
3. Pull the head harness over the crown of the head with the other hand (Fig. 14). Grasp the bottom straps, place them at the back of the neck and
hook them together (Fig. 15).
4. Pull the ends of the straps to adjust the tightness, beginning with the adjustment points on the head cradle and then moving to the adjustment
points at the back of the neck (Figs. 16 and 17). Do not over-tighten. Strap tension may be decreased by pushing out on back side of buckles.
5. Perform a positive and/or negative pressure user seal check each time the respirator is donned.
If you cannot achieve a proper fit, DO NOT enter contaminated area. 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.
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 the Brazil Respiratory Protection Program of the Ministry of Labor.
Positive Pressure User Seal Check
1. Tilt the head up slightly and cover the opening in exhalation valve cover with hand and exhale gently
(Fig. 18). If facepiece bulges slightly and no air leaks are detected between your face and facepiece, a proper seal has been obtained.
2. If air leakage is detected around the faceseal, reposition respirator on your face and/or readjust tension of the elastic straps to eliminate leakage.
Repeat the user seal check until a proper seal is obtained.
Care must be taken when performing the positive pressure seal check not to exhale too hard. The goal is to check the seal, not disturb the seal
between the facepiece and the face.
If you cannot achieve a proper seal, DO NOT enter contaminated area. See your supervisor.
Negative Pressure User Seal Check with 3M™ Cartridges, 6000 Series
1. Place palms of hands to cover face of cartridge or open area of 3M™ Filter Retainer 501 and inhale gently (Fig. 19). 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.
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 3M™ Filter Retainer 501 may aid respirator wearer in conducting a negative pressure user seal check.
Negative Pressure User Seal Check with 3M™ Filters, 2000 series
1. Place your thumbs onto the center portion of the filters, restricting airflow into the breathing tube of filters, and inhale gently (Fig. 20). 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.
2. If faceseal air leakage is detected, reposition respirator on face and/or readjust tension of straps to eliminate the leakage. Repeat the user seal
check until a proper seal is obtained.
Be careful not to disturb the respirator seal by pressing too forcefully during negative pressure seal checks.
