INSTRUCTIONS FOR USE AND CARE
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.
3. If the respirator does not perform as specified in
this manual, it must not be used until it has been
checked by authorized personnel.
4. DO NOT alter, modify, or substitute any components.
5. Inspect the respirator regularly and maintain it
according to the instructions. Repairs must only be
made by properly trained personnel.
6. This respiratory protective device does not supply
oxygen. Use only in adequately ventilated areas
which conform to the appropriate standard.
7. This respirator must be used in conjunction with
the proper cartridges for protection against specific contaminants. If you cannot determine that the
cartridges used with this device is designed for the
ontaminant, or if you do not know the identity of
c
the contaminant, do not use this device.
. DO NOT use when concentrations of contaminants
8
are unknown.
9. DO NOT block the cartridges.
10. DO NOT use when appropriate exposure limit (PEL,
REL, TLV, etc.) is not known.
1. Leave the contaminated area immediately if:
1
a. Breathing becomes difficult
b.Dizziness or other distress occurs
c. You taste or smell the contaminant
d.You experience nose or throat irritation
e. Instructed by responsible individuals
11. Use strictly in accordance with the instructions,
labels, and limitations pertaining to this device.
Follow an established canister/cartridge(s)
changeout schedule.
12. This respirator may not provide a satisfactory seal
with certain facial characteristics, such as beards
or large sideburns that prevent direct contact
between the skin and the sealing surface of the
facepiece. Do not use this facepiece if such conditions exist.
13. DO NOT wear eyeglasses under the facepiece. The

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 cartridge 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 cartridge life shall be predetermined based on a determination of the amount of contaminant in the atmosphere and the capacity of the cartridges together with the expected air flow through the
cartridges. An average airflow of approximately two cubic
feet per minute (2 CFM) will flow through each cartridge
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 Cartridges 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 battery.

DESCRIPTION
The C420 Respirator is a blower-assisted, air-purifying
espirator referred to as a Powered Air-Purifying
r
Respirator or a PAPR.
The filtering system consists of a waist-mounted batterydriven blower assembly device and two (2) cartridge-type
ilter media. The blower assembly contains an electric
f
motor driving an air blower. A compartment for a nonrechargeable 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 cartridges (sold separately). The user of
the respirator breathes ambient air after the air has
passed through the cartridges. The cartridges 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 cartridges and delivering the purified air
through a breathing tube to the facepiece. An airflow indicator (P/N S-30020) 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 cartridges installed, must be tested
with the airflow indicator both prior to use and at prescribed intervals during use to monitor battery life and
cartridge efficiency.
The C420 PAPR can be used with MSA Millennium
®
Facepiece and Ultra Elite®Facepiece. Refer to the separate NIOSH Approval Labels (P/N 10071373 and
10080165) for a complete list of approved part numbers
and limitations.
4. This respirator can be used for protection against a
ixture of contaminants that are present simultane-
m
ously or alternately against one contaminant then
nother (using the same cartridges or filters) if the
a
mixture meets the following conditions:
a. The cartridge/canister/filter must be approved for all
contaminants present.
b.Particulates (dusts, mists, fumes, asbestos,
adionuclides) can be mixed with any other particu-
r
late or any gas or vapor for which the cartridge/canister is approved.
c. Contaminants present simultaneously must be 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 TLV of a mixture.
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+ . . .
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 and hood PAPRs: 1000 times the
exposure limit for the contaminants present.
b.Half-facepiece PAPRs: 50 times the exposure limit
for the contaminants present.
c. 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.
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
undamaged. See the Inspection section for inspection
procedures.
2. Check that the cartridge or canister approval is appro-
riate and effective against the contaminant in the use
p
environment. Always use two MSA cartridges or can-
sters of the same type.
i
DO NOT cross thread any C420 PAPR components
during assembly. Cross threading can cause the connection to feel tight, but 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.
O NOT completely discharge a rechargeable battery.
D
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.
1. Ensure the blower switch is in the “OFF” position.
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
cartridges attached to the blower.
Note: See the Charging the C240 Rechargeable Battery
section for detailed battery charger use instructions.
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.
