percent oxygen.
B - Not for use in atmospheres immediately dangerous to
life or health.
C - Do not exceed maximum use concentrations estab-
lished by regulatory standards.
F- Do not use powered air-purifying respirators if airflow
is less than four cfm (115 lpm) for tight fitting face-
pieces or six cfm (170 lpm) for hoods and/or helmets.
H - Follow established cartridge and canister change
schedules or observe ESLI to ensure that cartridges
and canisters are replaced before breakthrough
occurs.
I – Contains electrical parts that may cause an ignition in
flammable or explosive atmospheres.

PAPR/CBRN APPLICATION
A- Not for use in atmospheres containing less than 19.5
percent oxygen.
F- Do not use powered air-purifying respirators if air flow
is less than four cfm (115 lpm) for tight fitting face-
pieces or six cfm (170 lpm) for hoods and/or helmets.
H- Follow established cartridge and cartridge change
schedules or observe ESLI to ensure cartridges and
canisters are replaced before breakthrough occurs.
I- Contains electrical parts that may cause an ignition
source in flammable or explosive atmospheres.
J- Failure to properly use and maintain this product
could result in injury or death.
L- Follow the manufacturer's User's Instructions for
changing canisters.
M- All approved respirators shall be selected, fitted,
used, and maintained in accordance with MSHA,
OSHA and other applicable regulations.
N- Never substitute, modify, add, or omit parts. Use only
exact replacement parts in the configuration as spec-
ified by the manufacturer.
O- Refer to User's Instructions, and/or maintenance
manuals for information on use and maintenance of
these respirators.
R- Some CBRN agents may not present immediate
effects from exposure, but can result in delayed
impairment, illness, and death.
S- Special or critical User’s Instructions and/or specific
use limitations apply. Refer to User’s Instructions
before donning.
T- Direct contact with CBRN agents requires proper
handling of the respirator after each use and between
multiple entries during the same use.
Decontamination and disposal procedures must be
followed. If contaminated with liquid chemical warfare
agents, dispose of the respirator after decontamina-
tion.
Y- This respirator provides respiratory protection against
inhalation of radiological and nuclear dust particles.
