GENERAL SAFETY INFORMATION
Intended Use

The 3M™ FR-M40 Full Facepiece Respirator is designed to help provide respiratory protection against
certain airborne contaminants when used in accordance with all use and limitation instructions and
applicable safety and health regulations.

These User Instructions are not designed to serve as a training manual for personnel with no previous
practical experience with air purifying respirators (APR). Contact 3M OH&ESD Technical Service
Department for more information on training programs available. For proper use, see supervisor, or
instructions, or call 3M Technical Service

CAUTION

The headstraps of this respirator contain natural rubber latex which may cause an allergic reaction.

This respirator helps reduce exposure to certain airborne contaminants but does not
eliminate exposure or the risk of contracting disease or infection. Misuse may result in
sickness or death. For proper use, see supervisor or User Instructions, or call 3M in
U.S.A., 1-800-243-4630. In Canada, call Technical Service at 1-800-267-4414.

• This respirator helps reduce exposure to certain airborne contaminants but does not eliminate

exposure or the risk of contracting disease or infection. Misuse may result in sickness or death. For
proper use, see your supervisor, product packaging or call 3M in U.S.A. at 1-800-243-4630. In
Canada call 3M at 1-800-267-4414.

• Use only 3M parts with this respirator.

• Do not use when airborne concentrations of contaminants exceed the maximum use concentration

(MUC)of the respirator. See Quantitative and Qualitative Fit Testing section of these User
Instructions.

• This respirator must be inspected before each use to ensure it is in proper operating condition. See

Inspection Procedure section.

• Before you enter a contaminated atmosphere wearing this respirator, you must inspect the respirator,

don the respirator according to the instructions provided with the components of the system you are
using and complete a User Seal Check. Failure to do so may affect respirator performance and may
result in sickness or death.

• Before removing the respirator, you must leave the contaminated area and be completely

decontaminated by following applicable decontamination protocols. Alternatively, have an individual,
who has not been contaminated, assist you with doffing.

• Before storing the respirator, be sure that the respirator has been decontaminated per applicable

decontamination protocols. If necessary, dispose of the equipment per applicable waste regulations.

• Do not connect or use the drinking system in contaminated atmospheres.

CAUTION

• Cleaning with solvents may degrade some respirator components and reduce respirator effectiveness.

See Maintenance and Cleaning section.

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

• The used cartridge must be disposed of in accordance with all applicable waste regulations.

• Avoid overstretching the holes in the universal second skin. To prevent tearing the exhalation valve

cover opening of the universal second skin, be careful pulling it over the flanges of the exhalation valve
housing.

• DS2 is a common agent used in the decontamination of equipment exposed to military chemical

warfare agents. DS2 may damage the front and side voicemitters of the mask assembly. When exposed
to DS2, rinse voicemitters with clean water.

Use For

3M recommends the use of this product to help reduce the respiratory exposure of wearers to certain
chemical and biological warfare agents when used in accordance with all use and limitation instructions
and applicable safety and health regulations.

3

Do Not Use For

Atmospheres with less than 19.5% oxygen, concentrations of contaminants which are immediately
dangerous to life or health, are unknown or when concentrations exceed the use limitations for the
cartridge/filter and facepiece specified in OSHA standards or applicable government regulations,
whichever is lower or exposure to industrial chemicals not included in the NIOSH approval.

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. The airborne contaminants which can be dangerous to your health include those that are so small you
cannot see them.

3. Before use, the wearer must first be trained by the employer in proper respirator use in accordance
with applicable safety and health standards.

4. U.S. Occupational Safety and Health Administration (OSHA) Standard 29 CFR 1910.134 and the
Canadian CSA Standard Z94.4 require a written respirator program and also require that the wearer
be fit tested before use.

5. Leave contaminated area immediately and contact supervisor if you smell or taste contaminants or if
dizziness, irritation, or other distress occurs.

Use Limitations

1. Do not use this respirator when the concentration of contaminants is unknown or immediately
dangerous to life or health (IDLH).

2. Do not use when concentrations exceed 10 times the permissible exposure limit (PEL) when
qualitatively fit tested or 50 times the PEL when quantitatively fit tested, or according to specific OSHA
standards or applicable government regulations, whichever is lower.

3. This respirator does not supply oxygen when used in the air-purifying mode. Do not use in
atmospheres containing less then 19.5% oxygen.

4. Do not alter, abuse or misuse this respirator.

5. Do not use with beards or other facial hair or other conditions that prevent a good seal between the
face and the faceseal of the respirator.

NIOSH Cautions and Limitations

The following restrictions may apply. See NIOSH approval label.
A- Not for use in atmospheres containing less than 19.5 percent oxygen.
B- Not for use in atmospheres immediately dangerous to life or health.

specified by the manufacturer.

O- Refer to User’s Instructions, and/or maintenance manuals for information on use and maintenance

of these respirators.

P- NIOSH does not evaluate respirators as surgical masks.
S- Special or critical User’s Instructions and/or specific use limitations apply. Refer to User’s

Instructions before donning.

S-Special or Critical Use Instructions

There is no NIOSH approval schedule for chemical or biological warfare agents; only the tear agents CN
& CS. Use of this respirator along with the FR-C2A1 or FR-64 cartridge helps reduce wearer exposure to
certain chemical and biological warfare agents when used in accordance with all use instructions and
applicable safety and health regulations but does not eliminate exposure or the risk of contracting disease
or infection.

Time Use Limitations

1. If respirator or cartridge becomes damaged, soiled, or breathing becomes difficult, leave the
contaminated area immediately and repair or replace the respirator or cartridge.

2. Replace filters in accordance with the filter Time Use Limitations. (See filter User Instructions.)

3. Replace cartridges in accordance with an established change schedule or earlier if smell, taste or
irritation from contaminants is detected.

General Description

The NIOSH approved 3MTM FR-M40 system is a negative pressure air purifying respirator (APR).
The facepiece attaches to the head by a series of six straps that are pulled tight to seal the facepiece around
the face and help minimize air leakage. The facepiece exhalation valve opens when air is exhaled, and
prevents external air from entering during inhalation.
Before use, the wearer must be trained by the employer in the proper donning, operation, inspection,
emergency procedures and maintenance of the APR. Training must be in accordance with and include
these User Instructions. Improper use may result in serious bodily injury or death.
