This respirator helps protect against certain particles. Misuse may result in sickness or
death. For correct use, consult supervisor and User Instructions. For more information
please contact 3M in China, 86-21-22105335.
IMPORTANT
Before use, wearer must read and understand these User Instructions. Keep these instructions for reference.
Use For
Particles such as those from grinding, sanding, sweeping, sawing, bagging, or processing minerals, coal, iron
ore, flour, metal, wood, pollen, and certain other substances. Liquid or non-oil based particles from sprays
that do not also emit oil aerosols or vapors. For additional information on 3M use recommendations for this
class of respirator please consult the 3M PSD web site at www.3M.com.cn/PPE or call 86-21-22105335 in
China.
Do Not Use For
Do not use for gases and vapors, oil aerosols, or sandblasting, unless nozzle and blast are physically
separated from the operator in an exhaust-ventilated enclosure; particulate concentrations that exceed either
10 times the occupational exposure limit or applicable government regulations, whichever is lower.* In the
U.S., do not use when the United States Occupational Safety and Health Administration (OSHA) substance
specific standards, such as those for asbestos, arsenic, cadmium, lead in the construction industry, or 4,4’-
methylene dianiline (MDA), specify other types of respiratory protection. This respirator does not supply
oxygen.
Biological Particles
This respirator can help reduce inhalation exposures to certain airborne biological particles (e.g. mold,
Bacillus anthracis, Mycobacterium tuberculosis, etc.) but cannot eliminate the risk of contracting infection,
illness or disease. OSHA and other government agencies have not established safe exposure limits for these
contaminants.
Use Instructions
1. Failure to follow all instructions and limitations on the use of this respirator and/or failure to wear this
respirator during all times of exposure can reduce respirator effectiveness and may result in sickness or
death.
2. Before occupational use of this respirator, a written respiratory protection program must be implemented
meeting all the local government requirements. In the United States, employers must comply with OSHA
29 CFR 1910.134 which includes medical evaluation, training and fit testing, and applicable OSHA
* For Use in China: Do not use for oil based particles. Do not use for particles in concentrations that
exceed the maximum allowable concentration required by the applicable regulation and standard. The
maximum allowable concentration is obtained by multiplying the Assigned Protection Factor (APF)
provided by GB/T 18664 “Selection, Use and Maintenance of Respiratory Protective Equipment” and
the permissible Occupational Exposure Limit (OEL) of the contaminant.

substance specific standards. In Canada, CSA standard Z94.4 requirements must be met and/or
requirements of the applicable jurisdiction, as appropriate. **
3. The particles which can be dangerous to your health include those so small that you cannot see them.
4. Leave the contaminated area immediately and contact supervisor if dizziness, irritation, or other distress
occurs.
5. Store the respirator away from contaminated areas when not in use.
6. Inspect respirator before each use to ensure that it is in good operating condition. Examine all the
respirator parts for signs of damage including the two headbands, attachment points and noseclip. The
respirator should be disposed of immediately upon observation of damaged or missing parts. Filtering
facepieces are to be inspected prior to each use to assure there are no holes in the breathing zone other
than the punctures around staples and no damage has occurred. Enlarged holes resulting from ripped or
torn filter material around staple punctures are considered damage. Immediately replace respirator if
damaged. Staple perforations do not affect NIOSH approval.
7. Dispose of used product in accordance with applicable regulations.
Use Limitations
1. This respirator does not supply oxygen. Do not use in atmospheres containing less than 19.5% oxygen.
2. Do not use when concentrations of contaminants are immediately dangerous to life and health, are
unknown or when concentrations exceed 10 times the permissible exposure limit (PEL) or according to
specific OSHA standards or applicable government regulations, whichever is lower. *
3. Do not alter, wash, abuse or misuse this respirator.
4. Do not use with beards or other facial hair or other conditions that prevent a good seal between the face
and the sealing surface of the respirator.
5. Respirators can help protect your lungs against certain airborne contaminants, however, they will not
prevent entry through other routes such as the skin, which would require additional personal protective
equipment (PPE).
6. This respirator is designed for occupational/professional use by adults who are properly trained in it’s use
and limitations. Respirators are not designed to be used by children.
7. Individuals with a compromised respiratory system, such as asthma or emphysema, should consult a
physician and complete a medical evaluation prior to use.
8. When stored in accordance with temperature and humidity conditions specified below, the product may
be used until the “use by” date specified on the packaging.
** For Use in China: For the selection, use and maintenance of respirator, please refer to China
national standard GB/T 18664.
* For Use in China: Do not use for oil based particles. Do not use for particles in concentrations that
exceed the maximum allowable concentration required by the applicable regulation and standard. The
maximum allowable concentration is obtained by multiplying the Assigned Protection Factor (APF)
provided by GB/T 18664 “Selection, Use and Maintenance of Respiratory Protective Equipment” and
the permissible Occupational Exposure Limit (OEL) of the contaminant.

Storage Conditions and Shelf Life
Before use, store respirators in the original packaging, away from contaminated areas, dust, sunlight, extreme
temperatures, excessive moisture and damaging chemicals. When stored in accordance with temperature and
humidity conditions specified below, the product may be used until the “use by” date specified on
packaging. Always inspect product and conduct a user seal check before use as specified in User
Instructions. If you cannot achieve a proper seal, do not enter the contaminated area. See your
supervisor.
Time Use Limitation
If respirator becomes damaged, soiled, or breathing becomes difficult, leave the contaminated area
immediately and replace the respirator.

1. Cup the respirator in your hand, with the nosepiece at your fingertips, allowing the headbands to hang
freely below your hand (Fig. 1).
2. Position the respirator under your chin with the nosepiece up. Pull the top strap over your head resting it
high at the top back of your head. Pull the bottom strap over your head and position it around the neck
below the ears (Fig. 2).
3. Place your fingertips from both hands at the top of the metal nosepiece. Using two hands, mold the nose
area to the shape of your nose by pushing inward while moving your fingertips down both sides of the
nosepiece (Fig. 3).
! Pinching the nosepiece using one hand may result in improper fit and less effective respirator
performance. Use two hands.
4. Perform a User Seal Check prior to each wearing. To check the respirator-to-face seal, place both hands
completely over the respirator and inhale sharply (Fig. 4). Be careful not to disturb the position of the
respirator. A negative pressure should be felt inside the respirator. If air leaks around nose, readjust the
nosepiece as described in step 3. If air leaks at the respirator edges, work the straps back along the sides
of your head. If you CANNOT achieve a proper fit, DO NOT enter the contaminated area. See
your supervisor.
