4. Adjust top straps fi rst, then lower neck straps by pulling on ends (Fig. 13). DO NOT pull too tight! (Strap tension

may be decreased by pushing out on back side of buckles.) Perform a positive pressure and/or negative pressure

user seal check. The positive pressure method is recommended.

If you cannot achieve a proper fi t, 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.

Positive Pressure Seal Check

1. Place the palm of your hand over the exhalation valve cover and exhale gently. If facepiece bulges slightly and no

air leaks are detected between your face and the facepiece, a proper fi t has been obtained (Fig. 14).

2. If faceseal air leakage is detected, reposition respirator on your face and/or readjust tension of the elastic straps

to eliminate leakage.

3. Repeat above steps until a tight faceseal is obtained.

If you cannot achieve a proper fi t, DO NOT enter contaminated area. See your supervisor.

Negative Pressure Seal Check (with 6000 series cartridges)

1. Place palms of hands to cover face of cartridge or open area of 3M™ 501 Filter Retainer, when retainer is

attached to the cartridge, to restrict air fl ow (Fig. 15).

2. Inhale gently. If you feel facepiece collapse slightly and pull closer to your face with no leaks between the face

and facepiece, a proper fi t has been obtained.

3. If faceseal air leakage is detected, reposition respirator on face and/or readjust tension of straps to eliminate air

leakage. Repeat above steps until a tight faceseal is obtained.

If you cannot achieve a proper seal, DO NOT enter contaminated area. See your supervisor.

NOTE: Use of 3M 501 fi lter retainer may aid respirator wearer in conducting a negative pressure seal check.

Negative Pressure Seal Check (with 2000 Series fi lters)

1. Place your thumbs onto the center portion of the fi lters, restricting airfl ow into the breathing tube of fi lters, and

inhale gently. If you feel facepiece collapse slightly and pull closer to your face with no leaks between the face

and facepiece, a proper fi t has been obtained (Fig. 16).

2. If faceseal air leakage is detected, reposition respirator on face and/or readjust tension of straps to eliminate the

leakage.

3. Repeat above steps until a tight faceseal is obtained.

If you cannot achieve a proper seal, DO NOT enter contaminated area. See your supervisor.

Negative Pressure User Seal Check (with 7093/7093C Filters)

1. Using hands press or squeeze fi lter covers toward facepiece and 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 (Fig. 23).

2. If faceseal air leakage is detected, reposition respirator on face and/or readjust tension of straps to eliminate the

leakage.

If you cannot achieve a proper seal, DO NOT enter contaminated area. See your supervisor.

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.

3. For Combination Dual Airline where cartridges or fi lters are attached perform user seal check as described above

under the appropriate cartridge or fi lter that is being used.

4. 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.

If you cannot achieve a proper seal, DO NOT enter contaminated area. See your supervisor.

NOTE: Before assigning any respirator to be worn in a contaminated area, a qualitative or quantitative fi t test

must be performed per OSHA Standard 1910.134 or CSA Standard Z94.4.

FIT TESTING

The effectiveness of a respirator will be reduced if it is not fi tted properly. Therefore, either quantitative or qualitative

fi t testing must be conducted prior to the respirator being issued.

NOTE: Fit testing is a U.S. Occupational Safety and Health Administration (OSHA), a Canadian CSA and a Brazilian

BMOL requirement.

Quantitative Fit Testing

Quantitative Fit Testing (QNFT) can be conducted using a 3M™ 601 Fit Test Adapter and P100 fi lters such as the

3M™ 2091 or 7093 P100 Particulate Filters.

Qualitative Fit Testing

Qualitative Fit Testing (QLFT) with the 3M™ FT-10 or FT-30 Qualitative Fit Test Apparatus can be conducted using any

of the NIOSH approved particulate fi lters.

Fit testing should be conducted using the heaviest cartridge, canister, fi lter or combination that each wearer will use

in their work environment. Respirators should also be fi t tested while wearing any personal protective equipment

(PPE) the wearer may use in their work environment that may affect the fi t of the respirator (e.g. hoods, hardhats,

safety glasses, hearing protections, etc.).
