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 fi lters, restricting airfl ow into the breathing tube of fi lters,

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.

Negative Pressure User Seal Check with 3M™ Filters 7093/7093C

1. Using hands squeeze or press fi lter covers toward facepiece and inhale gently (Fig. 21). 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 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 3M™ Dual Airline Respirator

1. If using the 3M™ Breathing Tubes SA-1500 or SA-2500, disconnect airline hose from air control valve.

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 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.

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.

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 fi tted properly. Therefore, either qualitative

or quantitative fi t 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. 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, hearing protectors, etc.). For further information concerning fi t testing,

contact 3M PSD Technical Service.

• Quantitative Fit Testing: Quantitative Fit Testing (QNFT) can be conducted using a 3M™ Fit Test Adapter

601 and P100 fi lters 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 fi lters.

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 diffi cult.

Your 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 defi cient.

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 specifi c respirator system or the APF mandated by specifi c

government standards, whichever is lower.

INSPECTION, CLEANING, AND STORAGE

Failure to follow these instructions may reduce respirator performance, expose you to

contaminants above the OEL, and may result in sickness or death.

• Do not clean respirator with solvents. Cleaning with solvents may degrade some respirator

components and reduce respirator effectiveness.

• Inspect all respirator components before each use to ensure proper operating condition.

Inspection Procedure

This respirator must be inspected before each use and at the time of cleaning to ensure it is in good

operating condition. Any damaged or defective parts must be replaced before use. Do not enter a

contaminated area with damaged or defective parts. The following inspection procedure is recommended.

1. Check facepiece for cracks, tears and dirt. Be certain facepiece, especially faceseal area, is not distorted.

2. Examine inhalation valves for signs of distortion, cracking or tearing.

3. Make sure straps are intact and have good elasticity.

4. Examine all plastic parts for signs of cracking or fatiguing. Ensure bayonet gaskets are in good condition.

5. Remove exhalation valve cover (see Head Harness Assembly & Valve Cover Replacement procedure)

and examine exhalation valve and valve seat for signs of dirt, distortion, cracking or tearing. Replace

exhalation valve cover.

Cleaning and Storage

Cleaning is recommended after each use.

1. Remove cartridges, fi lters and/or breathing tubes. The exhalation valve cover, exhalation valve and

inhalation valves can also be disassembled if necessary.

2. Clean facepiece (excluding fi lters and cartridges), by immersing in warm cleaning solution, water

temperature not to exceed 120°F (49°C), and scrub with soft brush until clean. Add neutral detergent if

necessary. Do not use cleaners containing lanolin or other oils.

3. Disinfect facepiece by soaking in a solution of quaternary ammonia disinfectant or sodium hypochlorite

(1 oz. [30 mL] household bleach in 2 gallons [7.5 L] of water), or other disinfectant.

4. Rinse in fresh, warm water and air dry in non-contaminated atmosphere.

5. Respirator components must be inspected prior to each use. A respirator with any damaged or

deteriorated components should be repaired or discarded.

6. The cleaned respirator should be stored away from contaminated areas when not in use.
