The 3M™7500 Series half mask can be used with a variety of different
filter/product options:
3M™Gas an vapour filters – All the 6000 Series filters
listed overleaf fit directly onto the 7500 Series half masks
(e.g 6051, 6055 etc)
3M™Particulate filters – the 2000 Series, 6035 and 6038 filters fit
directly onto the 7500 Series half masks.
The 5911 / 5925 / 5935 particulate filters can only be used on their
own if used with the platform 603 & retainer 501.
A combination of gas / vapour an particulate filters – the 5911 /
5925 / 5935 particulate filters can be used with the 6000 series gas /
vapour filters (except 6096) using retainer 501.
Note: The 6098 or 6099 filters should not be used with 7500 series half
masks.
Approvals
The 7500 Series half masks and 6000 / 5000 / 2000 Series filters have
been shown to meet the Basic Safety Requirements under Article 10
and 11B of the European Community Directive 89/686, and are thus CE-
marked.

Correct Usage
●The 7500 Series facepiece, when fitted with 6000 Series gas/vapour
filters may be used in concentrations of gases or vapour (types
specified by 3M) up to 10 times WEL▲or 1000ppm (5000ppm for
6055) whichever value is lower (APF=10)*. Gas / vapour filters
should not be used to protect the wearer against a gas or vapour
that has poor warning properties.
●The 7500 Series facepieces when used with the 5911 filter may
be used in concentrations of solid and aqueous aerosols up to 4
times WEL▲(APF=4)*.
●The 7500 Series facepieces when used with the 5925, 2125 or
2128 filters may be used in concentrations of particulates up to
10 times WEL▲(APF=10)*.
●The 7500 Series facepieces when used with the 5935, 2135,
2138, 6035 or 6038 may be used in concentrations of particulates
up to 20 times WEL▲(APF=20)*.
●The 7500 Series facepieces when used with the 2128 and
2138 may be used to protect against ozone up to 10 times
WEL▲(APF=10)* and to offer relief from nuisance odours and
acid gases below the WEL▲.
●The 7500 Series facepieces when used with the 6038 filter may be
used to protect against ydrogen Fluoride gas up to 30ppm and offer
relief from Ozone, Organic Vapours and acid gases below WEL.

Cleaning and Storage
1. Cleaning is recommended after each use. Remove the filters.
2. Clean the facepiece (excluding filters) with 3M™105 Face Seal
Cleaners or by immersing in warm cleaning solution, water
temperature not to exceed 50°C and scrub with soft brush until
clean. Add neutral detergent if necessary. Do not use cleaners
containing lanolin or other oils.
3. Rinse in fresh, warm water and air dry in a non-contaminated
atmosphere.
4. Respirator components, especially exhalation valve and seat,
should be inspected prior to each use. Any damaged or
deteriorated components should be replaced.
5. The cleaned respirator should be stored away from
contaminated areas when not in use.
Fitting Instructions
Fitting instructions must be followed each time the respirator is worn.
Stan ar Suspension
1. Adjust head cradle size to fit comfortably on head.
2. Place the respirator over the mouth and nose.
3. Pull the head harness over the crown of the head.
Drop Down Suspension
1.

2. Adjust head cradle size to fit comfortably on head.
3. While holding head harness strap ends with one hand, slide
the facepiece up onto your face as shown below.
Both Types of Suspension
4. Take the bottom straps in both hands, place them at the back
of the neck and hook them together.
5. Tighten the top straps first by pulling on ends to achieve a
comfortable and secure fit as shown.
6. Tighten bottom straps using the rear adjustments (strap
tension may be decreased by pushing out on back side
of buckles).
7. Perform a positive and/or negative pressure face fit check.
Face Fitting
The negative pressure fit check is recommended when using the 6035,
6038 and 2000 Series filters; the positive pressure fit check is
recommended when using other filters.
Positive Pressure Facefit Check
Place the palm of the hand over the exhalation valve cover and exhale
gently.
If the facepiece bulges slightly and no air leaks between the face and
the facepiece are detected, a proper fit has been achieved.
If air leakage is detected, reposition the respirator on the face and/or
readjust the elastic strap to eliminate the leakage.
Repeat the above facefit check.
Negative Pressure Facefit Check
For the 2000 Series filters, press your thumbs into the central
indentation of the filters, inhale gently and hold your breath for five or
ten seconds.
For the 6035 and 6038 filters, pinch the filter between thumb and
fingers to seal the filter cover to the body of the filter, inhale gently and
hold your breath for five or ten seconds.
If the facepiece collapses slightly a proper fit has been achieved.
If air leakage is detected, reposition the respirator on the face and/or
readjust the elastic strap to eliminate the leakage.
Repeat the above facefit check.
Fit Testing
The 3M 7500 alf Mask is a tight fitting facepiece and therefore
requires a fit test per wearer before use as per the COS regulations
2002.
For qualitative fit testing - 3M FT10 or FT30 fit test kits are available.
For quantitative fit testing - the 3M 601 adaptor is available.

3M™Spare Parts and Accessories
Due to the small number of components used in the 3M™7500 Series
respirators, routine maintenance can be conducted with ease.
Use limitations
1. These respirators do not supply oxygen. Do not use in
oxygen deficient areas*
2. Do not use for respiratory protection against atmospheric
contaminants which have poor warning properties, are
unknown or immediately dangerous to life and health or
against chemicals which generate high heats of reaction with
chemical filters.
3. Do not modify or alter this device.
4. The assembled respirator may not provide a satisfactory face
seal with certain physical characteristics (such as beards or
large side burns) resulting in leakage between the facepiece and
the face, the user assumes all risks of bodily injury which may
possibly result.
5 Do not use with unknown concentrations of contaminants.
6 Do not use for escape purposes.
7. Leave the work area immediately and check the integrity of
the respirator and replace facepiece and / or filters if:
i) Damage has occurred or is apparent.
ii Breathing becomes difficult or increased breathing
resistance occurs.
iii) Dizziness or other distress occurs.
iv) You taste or smell the contaminant or an irritation
occurs.
8. Store this device in a sealed container away from
contaminated areas when not in use.
9. Use strictly in accordance with facepiece and filter user
instruction leaflet.
* 3M definition minimum 19.5% by volume oxygen
Respiratory protection is only effective if it is correctly selecte ,
fitte an worn throughout the time when the wearer is expose to
respiratory contaminants.
3M offers a vice on the selection of pro ucts an training in the
correct fitting an usage.
