DANGER
CBRN APPLICATION
• This respirator provides LIMITED protection. It is
NIOSH approved for respiratory protection against
atmospheres containing CBRN (chemical, biological, radiological, and nuclear) warfare agents; how-
ver, it cannot protect against all possible warfare
e
agents.
• Some CBRN agents may not present immediate
effects from exposure, but can result in delayed
impairment, illness, or death.
• DO NOT use without a complete understanding of
the instructions and limitations for this respirator
and proper training. Misuse can prevent the respirator from providing the necessary protection.
• CBRN agents may NOT be detectable by smell or
sight. Don respirator before entering an area suspected of containing CBRN agent. Follow procedures established by proper authorities.
• DO NOT use this respirator beyond eight (8) hours
after initial use in an atmosphere containing CBRN
agents or beyond two (2) hours after initial use in
an atmosphere containing CBRN agents in liquid of
mist form; otherwise agent permeation may occur.
• DO NOT remove respirator until respirator and
clothing are decontaminated; otherwise exposure
to CBRN agent may result. Follow decontamination
and disposal procedures established by appropriate authorities.
1. An adequate respiratory protection program must
include knowledge of hazards, hazard assessment,
selection of proper respiratory protective equipment, instruction and training in the use of equipment, inspection and maintenance of equipment,
and medical surveillance.
2. This respirator will perform as designed only if
used and maintained according to the manufacturer's instructions. The Program Administrator and
the users must read and understand these instructions before using or servicing this product.

INSTRUCTIONS FOR USE AND CARE
The C420 PAPR must be properly prepared for use, flow
ested, properly donned, and a negative pressure leak test
t
must be conducted in an area known to be free of conta-
inants before it can be used.
m
Before entry into a contaminated area, the maximum safe
duration of use must be estimated. The maximum safe
duration of use depends primarily on:
The amount and type of contamination in the air and
•
the capacity of the canister to absorb or neutralize
that contaminant.
• The amount of airborne particles (dust) in the atmosphere.
• The charge contained in the battery.
• The physiological limits of the respirator user.
The maximum expected canister life shall be predetermined based on a determination of the amount of contaminant in the atmosphere and the capacity of the canisters together with the expected air flow through the canisters. An average airflow of approximately two cubic feet
per minute (2 CFM) will flow through each canister during
prolonged use.
The single use battery may be used up to eight (8) hours
nder certain conditions. The rechargeable battery may
u
be used for up to four (4) hours under certain conditions.
ir flow must be checked as described in these instruc-
A
tions for maximum protection.
After four (4) hours of use, the user must leave the contaminated area, decontaminate if required, and check the
irflow with the Airflow Indicator (Refer to the Flow Test
a
with Canisters Installed section) when using the single use
battery. Thereafter, the air flow must be checked at least
every two (2) hours of use. (Refer to the In-Use Flow Test
section) After four (4) hours of use the user must leave the
contaminated area, decontaminate if required, and discontinue using the respirator when using the rechargeable

DESCRIPTION
The FireHawk M7 Responder PAPR Respirator is a blow-
r-assisted, air-purifying respirator referred to as a
e
Powered Air-Purifying Respirator or a PAPR.
The filtering system consists of the C420 waist-mounted
battery driven motor-blower assembly device and two (2)
anister-type filter media. The blower assembly contains
c
an electric motor driving an air blower. A compartment for
a non-rechargeable 6 volt (nominal) lithium-sulfur dioxide
(LiSO2) battery pack or a rechargeable 4.8 volt (nominal)
nickel-metal hydride (NiMH) battery pack is located on the
bottom of the blower assembly. There are two (2) threaded inlets on the front of the blower assembly for the
attachment of the canisters (sold separately). The user of
the respirator breathes ambient air after the air has
passed through the canisters. The canisters include a
mechanical filter to trap airborne particles and may also
include a sorbent bed of impregnated activated carbon to
trap and/or neutralize various gases/vapors.
The blower assembly assists breathing by drawing air
through the canisters and delivering the purified air
through a breathing tube to the facepiece. An airflow indicator used to check for minimum airflow is provided with
the C420 PAPR filtering system. To maintain respiratory
protection:
• The user must be properly fit tested to the respirator
facepiece before use (refer to the appropriate
Facepiece User Instructions Manual)
• The blower, with canisters installed, must be tested
with the airflow indicator both prior to use and at prescribed intervals during use to monitor battery life and
canister efficiency.
another (using the same canisters or filters) if the mix-
ure meets the following conditions:
t
a. The canister/filter must be approved for all contami-
ants present.
n
b. Particulates (dusts, mists, fumes, asbestos,
radionuclides) can be mixed with any other particulate or any gas or vapor for which the canister is
approved.
. Contaminants present simultaneously must be
c
below IDLH levels for the specific contaminants. If
any one contaminant in the mixture exceeds the
IDLH concentration then the entire mixture must be
treated as IDLH and the respirator cannot be used
(except for escape from particulates with appropriate filter).”
EXPOSURE LIMITS
A listing of acceptable exposure limits from the following
sources is provided in MSA’s Response® Respirator
Selector:
- American Conference of Governmental Industrial
Hygienists (ACGIH)
- Occupational Safety and Health Administration
(OSHA)
- National Institute for Occupational Safety and Health
(NIOSH)
- American Industrial Hygiene Association (AIHA)
Contact MSA at 1-800-MSA-2222 for information.
Exposure Limits for Mixtures
The American Conference of Governmental Industrial
Hygienists (ACGIH) publishes the following information to
determine the Threshold Limit Value (TLV) of a mixture.
The FireHawk M7 Responder PAPR can be used with the
FireHawk M7 Responder APR. Refer to the separate
NIOSH Approval Label (P/N 10086005) for a complete list
of approved part numbers and limitations.
RESPIRATOR USE LIMITATIONS
The respirator must not be worn in atmospheres which
exceed any of the following limitations:
1. Maximum use concentrations
a. Full facepiece: 1000 times the exposure limit for the
contaminants present.
b. 1000 parts per million organic vapors (for organic
vapor respirators).
2. The limitations outlined in the applicable NIOSH
approval.
3. Any applicable limitation contained in a standard
established by a regulatory agency (such as OSHA)
with jurisdiction over the wearer.
4. This respirator can be used for protection against a
mixture of contaminants that are present simultaneously or alternately against one contaminant then
First determine the total concentration of the chemical
mixture (C
centrations (C1, C2, C3, . . . ) using the following formula:
C
Mixture=C1+C2
Mixture
) from the individual contaminant con-
+ C3+ . . .
The TLV of the mixture is found by using the following formula where T1, T2, T3, . . . are the individual contaminant
TLVs and C1, C2, C3, . . . are the individual contaminant
concentrations:
Only use these equations if the contaminants present are
actually mixed. Some substances do not mix and may be
present separately, for example, in pockets or at different
levels. In that case, the lowest TLV of the substances present must be used to determine the appropriate respirator
category for protection against all contaminants present.

PREPARING THE C420 PAPR FOR USE
CHECKPOINTS BEFORE USE
1. Check that all parts of the respirator are complete and
ndamaged. See the Inspection section for inspection
u
procedures.
2. Check that the canister approval is appropriate and
effective against the contaminant in the use environment. Always use two MSA canisters of the same
ype.
t
DO NOT cross thread any C420 PAPR components
during assembly. Cross threading can cause the connection to feel tight, and a sufficient seal would not be
achieved. Failure to follow this warning can result in
serious personal injury or death.
INSTALLING THE WAISTBELT
1. Note the lacing path of the belt through the male
buckle.
2. Remove the male buckle and keeper loop from the
end of the belt.
3. Thread the belt through the two belt loops on the back
of the blower assembly.
4. Replace the keeper loop and lace the male buckle
back onto the belt.
Note: Ensure the belt is properly tightened so that the
C420 PAPR blower does not fall off or slide down the
body during use.
When powering the blower assembly with the NiMH
attery Pack, use the green battery cap assembly sup-
B
plied with the NiMH Battery Pack.
DO NOT completely discharge a rechargeable battery.
Rechargeable batteries must not be used for more
han four (4) hours at a time. Failure to follow this cau-
t
tion can result in reduced airflow and can cause the
battery to be permanently damaged.
Installing the Green Battery Cap Assembly (for NiMH
Battery Packs only)
1. Remove the black battery cap assembly by turning it
counter-clockwise.
2. Feed the split ring on the retaining lanyard through the
securing hole on the C420 PAPR blower housing.
3. Retain the black cap assembly for possible future use
with LI-SO2 Battery Packs.
4. Attach the green battery cap assembly by feeding the
split ring on the retaining lanyard completely through
the securing hole on the C420 PAPR blower housing.
Installing the Battery Pack into the Battery
Compartment of the Blower Assembly
DO NOT use any battery which shows signs of damage, such as bulging, swelling, disfigurement, or liquid
in the plastic wrap. Failure to follow this warning can
result in serious personal injury or death.
INSTALLING THE BATTERY PACK
Note: Each battery cap assembly has a retaining lanyard
to prevent loss.
Lithium-Sulfur Dioxide (LI-SO2) Battery Pack
When powering the blower assembly with the LI-SO2
Battery Pack, use the black battery cap assembly supplied with the C420 PAPR blower assembly.
Nickel-Metal Hydride Battery Pack
Note: Before initial battery pack use, or if battery pack
has not been used for an extended period of time (several
months), perform (3) 6-hour charge/4-hour discharge
cycles for optimum battery performance. The discharge
cycles should be completed with the blower running in a
non-hazardous environment, with no breathing tube or
canisters attached to the blower.
Note: See the Charging the C420 Rechargeable Battery
section for detailed battery charger use instructions.
1. Ensure the blower switch is in the “OFF” position.
Note: Damage may occur to the battery if the switch is
left in the “ON” position when the battery is installed.
2. Remove the battery cap assembly from the C420
PAPR blower by turning it counter-clockwise.
3. Remove the battery from its packaging.
4. Inspect the battery for signs of damage.
The Lithium-Sulfur Dioxide (LI-SO2) Battery Pack used
in this equipment contains pressurized Sulfur Dioxide
(SO2) gas. The gas is toxic and the battery must not
be abused in any way which may cause the battery to
rupture. DO NOT handle the battery directly if you
detect an odor like that of vinegar or rotten eggs.
Such odor indicates exposure to battery gas leakage,
which can lead to serious personal injury or death.

DONNING AND USE
DONNING
Note: Refer to the FireHawk M7 Responder APR user
nstructions for facepiece donning instructions.
i
• Donning, doffing, and obtaining and checking for a
roper facepiece seal must be done in an area
p
known to be free of contaminants. The user must
have practiced this procedure before attempting to
use the respirator for respiratory protection.
Failure to follow this warning can result in serious personal injury or death.
Donning the Blower Assembly
1. Examine the breathing tube assembly to verify that it
is properly tightened to the facepiece, the APR breathing tube/PAPR breathing tube extension interface, and
the blower assembly.
2. Examine the canisters to verify that they are properly
installed to the blower assembly.
3. Turn the switch to the “ON” position to confirm that
the battery is installed and the blower assembly is
working.
4. Turn the switch to the “OFF” position.
5. Don the waistbelt with the blower assembly with the
C420 PAPR blower outlet located at the top of the
unit.
6. Fasten the buckle and adjust the waistbelt.
Note: Refer to the FireHawk M7 Responder APR user
instructions for facepiece donning instructions (P/N
10086002).
Note: The C420 PAPR may be used with either a standard
8” (P/N 10082517) or a long 22” (P/N 10082542) APR
1
breathing tube.
Note: Use a buddy, if the situation permits, to ensure that
the C420 PAPR is donned correctly (the head harness is
in place, the blower is positioned correctly, the waist belt
is secure, and all components are properly assembled
nd tightened).
a
NEGATIVE PRESSURE SEAL TEST
The Negative Pressure Seal Test must be performed each
time the facepiece is donned. A good face-to-facepiece
seal must be verified before entering a hazardous area.
Perform the test as follows:
1. Ensure respirator is assembled properly.
2. Close off the inlet side of both canisters by placing
palms of the hands over canister inlets and press firmly to seal inlets.
3. Inhale gently and hold breath for 10 seconds. If the
seal is good, the facepiece will collapse and remain
collapsed against face. Remove hand and breathe
normally.
4. If the facepiece did not remain collapsed during the
test, or any leakage is noticed, check each canister
and breathing tube connection for looseness or cross
threading. Perform Negative Pressure Seal Test again.
5. If this does not correct the leak, the facepiece will not
provide protection. If the leakage is from the face seal,
a different size mask may be tried. If other than face
seal leakage is detected, the cause of the leak must
be corrected before performing another test.
The C420 PAPR blower may be worn in multiple locations
from either the left hip to the back. When the respirator is
donned, ensure:
• That the breathing tube is not excessively tight. During
use there should be no movements that can cause the
breathing tube to become tight and pull the facepiece
away from the face which could break the facepiece
seal.
• That the breathing tube is not excessively loose.
During use there should not be enough slack in the
breathing tube such that it could get caught on something and pull the facepiece away from the face which
could break the facepiece seal.
If either one of these conditions is present, one of the following actions must be taken:
• Change the position of the blower on the waist to create or remove slack in the breathing tube.
• Use a different length breathing tube to create or
remove slack in the breathing tube.
Note: Protective clothing and headwear, if used, must be
arranged so that it does not interfere with the fit of the
facepiece or restrict airflow to the canisters.
This device may not seal properly with your face if you
have a beard, gross sideburns or similar physical
characteristics (see ANSI Z88.2). An improper facial
seal may allow contaminants to leak into the facepiece, reducing or eliminating respiratory protection.
Do not use this device if such conditions exist. The
negative pressure seal test must be conducted and
passed before each use. Never remove the facepiece
except in a safe, non-hazardous, non-toxic atmosphere. Failure to follow this warning can result in serious personal injury or death.
