Fit Testing - 3M 6500 Serie Instrucciones De Uso

Negative Pressure User Seal Check with 3M™ Filters 7093/7093C
1. Using hands squeeze or press filter 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 filters are attached, perform user seal check as described above under the appropriate cartridge
or filter 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 29 CFR 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 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. Fit testing should be conducted using the heaviest cartridge, canister, filter or combination that each wearer will use in their
work environment. 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,
°
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 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.
