WARNING•

Respirator Capabilities andLimitations••

Selection of appropriate respiratory
protective equipment (RPE) will
depend on each situation and should
be made only by a competent person
knowledgeable of the actual working
conditions and the limitations of RPE.
Refer to applicable government
regulations regarding respirator selection,
which take precedence over a respirator
manufacturer’s guidance. In the U.S.,
please see www.osha.gov
or https://multimedia.3m.com/mws/
media/219161O/3m-regulationshandbook-respiratory-protection.pdf for
more information.

•

•

•

Respirators help protect against certain
airborne contaminants, but no respirator
is capable of preventing all airborne
contaminants from entering the wearer’s
breathing zone.
Hazardous airborne contaminants inthe workplace must be identified andquantified. Many contaminants that canbe dangerous to a person’s health cannot
be seen or smelled at dangerous levels.
Do not use respirators when airborne
contaminant concentrations exceed
maximum use concentrations establishedby regulatory agencies.
Only use self-contained breathingapparatus (SCBA) or combination
supplied air/SCBA when concentrations
are unknown, or in atmospheres
containing less than 19.5% oxygen. Air
purifying respirators do notsupply oxygen.

•

•

•

Before use, the wearer must readand understand the respirator User
Instructions. Failure to follow all
instructions and limitations on the useof these respirators and/or failure towear them properly during all times
of exposure can reduce respirator
effectiveness and may result insickness or death.
Before use of any respirator, the wearer
must first be trained by their employer inproper respirator use in accordance withapplicable safety and health standards.
In the U.S., a written respiratory
protection program must be
implemented meeting all therequirements of OSHA 29 CFR 1910.134
including training, fit testing, and medical
evaluation. In Canada, CSA standard
Z94.4 requirements must be met and/or requirements of the applicablejurisdiction, as appropriate.

•

•

•

•

Leave the contaminated area immediately
if dizziness or other distress occurs,
if the respirator becomes damaged
or breathing becomes difficult, if
contaminants can be smelled or tasted, or
if irritation occurs.
Do not use tight-fitting respirators orloose-fitting facepieces with beards orother facial hair or conditions that prevent
direct contact between the face and theedge of the respirator.
Maintenance, cleaning, and storage
programs must be established androutinely followed for respirators that arereused.
For correct use, consult supervisor andUser Instructions, or call 3M Personal
Safety Division (PSD) Technical Service
in the U.S.A. at 1-800-243-4630. In
Canada, call 1-800-267-4414.

How to Use This Guide

How to Use This Guide

Contaminants

1. Identify the air contaminants present in
the workplace and list them on the form
contained in this guide or on your own
form. If contaminants are unknown, or inatmospheres containing less than 19.5%
oxygen, use only self-contained breathingapparatus (SCBA) or combination supplied
air/SCBA for the respirator type.

Respirators are normally selectedbased upon workplace contaminants,
concentrations, application specificrequirements and human factors.

2. Look up each of your contaminants in thisguide. Enter the suggested type of filters
and/or cartridges or supplied air (SA) in theform. An explanation of the abbreviations
is given at the end of the guide.
Note:• If airborne oil mist is present in addition
to your listed contaminants, then aR- or P-series or HEPA filter must be
selected instead of a N-series filter.
• If any of the contaminants are being
aerosolized (e.g. sprayed), then aparticle filter must be added if notalready included.
• For powered air purifying respirators(PAPRs), use a HEPA filter instead of
the N, R or P type particle filters listed
in the guide.
On the bottom row, list the type of filter and/or cartridge that is applicable for ALL of thecontaminants together on your form. If SA issuggested for any of the contaminants, or if
there is no sufficient cartridge/filter for all of
the contaminants together, then SA must
be used.

3. Where applicable, list contaminant air
concentrations considered immediately
dangerous to life or health (IDLH) on theform. IDLH values are published by the
National Institute for Occupational Safety
and Health (NIOSH) https://www.cdc.
gov/niosh/idlh/default.html , but OSHA
allows employers to use other IDLH
values. The lower explosive level (LEL)or the concentration that would result inan oxygen deficient atmosphere should
also be considered IDLH. If contaminant
exposure levels are potentially at or above
IDLH, use only self-contained breathingapparatus (SCBA) or combination supplied
air/SCBA for the respirator type.

•Time Weighted Average (TWA)
exposure limits are for an eight (8)hour workday and a forty (40) hour
workweek.
• Short-Term Exposure Limits (STEL) area 15-minute time weighted average
exposure.
• Ceiling (C) exposure limits refer toconcentrations that should not be
exceeded during any part of theworkday.
If you have extended work shifts, or multiple
contaminants with similar health affects you
may wish to adjust the OELs—see an industrial
hygienist for assistance.

4. Enter the occupational exposure limits(OELs) on the form. References for OELs
include www.OSHA.gov for permissible
exposure limits (PELs) or www.acgih.
org for threshold limit values (TLV®s).
Depending on the contaminant you may
need to enter more than one type of OEL
based on the duration and variability of
exposure levels:

5. Determine contaminant air concentrations
and list them on the form. Air samplingin the worker’s breathing zone is highly
recommended. Consideration should begiven to the 8 hour time weighted average(TWA), 15 minute short term and peak(ceiling) exposures, while keeping in mind
seasonal and worker variability and thespecific process being used.

6. Calculate the hazard ratio (HR) as theairborne contaminant concentration /OEL. Enter the hazard ratio on the form.
7. Choose a respirator type with an assigned
protection factor (APF) that is higher thanthe hazard ratio. Assigned protection
factors* per OSHA 29 CFR 1910.134 are
as follows:
Air Purifying Respirators• Half facepiece (filtering facepiecedisposable and reusable): 10• Full facepiece (with quantitative fit
testing): 50
Powered Air Purifying Respirators• Loose-fitting facepiece: 25• Half facepiece: 50• Full facepiece, helmet, or hood: 1000**
Supplied Air Respirators (airline)• Continuous Flow
–Loose-fitting facepiece: 25–Half facepiece: 50–Full facepiece, helmet, or hood: 1000**• Pressure demand with full
facepiece: 1000
Self-Contained Breathing Apparatus(SCBA)• Pressure demand airline with escape
SCBA: 10,000 unknown and IDLH
atmospheres• Pressure demand SCBA: 10,000
unknown and IDLH atmospheres*Assigned protection factors may vary
based on specific standards such as thosepromulgated by U.S. OSHA. Where assigned
protection factors in local, state, or federal
standards are lower than those listed here,
they should be used instead. For additional
limitations of 3M respiratory protection
products, refer to 3M respirator packaging
and User Instructions.
** Respirator manufacturer must provide

and Other Considerations

data demonstrating performance of 1000 or
greater, otherwise APF of 25.

Other Considerations• If a gas/vapor cartridge is selected, achange schedule must be implemented,
otherwise supplied air respirators must be
used instead.
• If any of the respirator codes containthe (F) designation, respirators withhalf facepieces cannot be used unlessappropriate eye protection is also worn.
• If a chemical can be absorbed throughthe skin, skin protection may be requiredin addition to respiratory protection. Eyeprotection may also be necessary if notprovided by the respirator. Failure toprovide adequate skin or eye protection
can invalidate established exposure limits
and make respirator use ineffective for4

protection against certain
workplace contaminants.

Application Specific Requirements
and Human Factors
Consider the entire package of safety
equipment required for the job. The
respirator selected must be compatible withhard hats, goggles, glasses, welding hoods,
face shields, etc. In addition, the worker
must be able to communicate and perform
required job duties without removing
the respirator. If strenuous work is to be
performed, or if the respirator is to be wornfor an extended period of time, it may bedesirable to select a lightweight respirator
with low breathing resistance. If a respirator
does not have good worker acceptance oris not worn consistently, it will not provide
the expected protection.
When specifying supplied air respirators,
consider the distance the worker must travel
to get to an uncontaminated work area,

as well as obstacles or equipment present
in the area. If ladders or scaffolds must be
climbed, a supplied air respirator with air line
may not be appropriate.

Selection Guide Format Explanation
ContaminantContaminant names listed in this guide are
generally those used in the Threshold Limit
Values and Biological Exposure Indicespublished by the American Conferenceof Governmental Industrial Hygienists(ACGIH). Pesticides and chemicals withoutestablished occupational exposure limits are
not included. Call 3M Technical Service forassistance in selecting respirators forthese chemicals.

CAS#
Chemical abstract service registry numbers
were established by the American Chemical
Society to harmonize chemical identification
regardless of the synonym used ordifferences in spelling.
Synonyms
Several common synonyms are listed in thiscolumn.
Respirator Type
This column lists the suggested type ofparticulate, gas/vapor, or supplied air
respirator. The abbreviations used are
explained at the end of this document.
Not all of these respirators have been
specifically tested against each compound
listed. Either specific testing or a review
of chemical and physical properties of thematerials, as well as adsorption or filtration

characteristics of the respirators, forms thebasis for the recommendations.

be considered.

increased breathing resistance/reduced
air flow.

The recommendations are for single
substances. When two or more substances
are present, a combination respirator may
be appropriate. For example, with a spraypaint that contains organic solvents andtitanium dioxide, a respirator consisting of anorganic vapor cartridge and a particle filter
may be appropriate. In cases where an air
purifying respirator is not available for all of
the substances of concern in a mixture, a
supplied air respirator may be required.

Particulate Filter Definitions
N-Series filters may be used for solid or liquid
airborne particulates that do not contain oil.

Oils are mineral, vegetable and synthetic
substances and animal and vegetable fatsthat are generally slippery, combustible,
viscous, liquid or liquefiable at room
temperatures soluble in various organic
solvents such as ether but not in water.

In some cases, the respirator is precededby an “(F)” designation. These contaminants
have been identified as potential eye irritants.
Full facepieces, hoods, helmets or loose
fitting facepieces, or half facepieces with

R-Series filters may be used for solid or
liquid airborne particulates including oilbased aerosols. If the atmosphere contains
oil, R-series filters are limited to 8 hours ofcontinuous or intermittent use.
P-Series filters may be used for solid or liquid
airborne particulates including oil-based
aerosols. NIOSH requires that respirator
manufacturers establish time-use limitations
for all P-series filters. 3M recommends that in
atmospheres containing oil aerosols, P-series
filters are limited to 40 hours of use or 30
days, whichever occurs first.

95 level filter is > 95% filtration efficiency per
the NIOSH 42 CFR 84 test method.
