1 Safety Regulations
1.3 NIOSH Cautions and Limitations of Use for Chemical, Biological, Radiological, and Nuclear (CBRN)
Applications
A- Not for use in atmospheres containing less than 19.5 percent oxygen.
J- Failure to properly use and maintain this product could result in injury or death.
L- Follow the manufacturer's User Instructions for changing cartridges, canisters and/or filters.
All approved respirators shall be selected, fitted, used and maintained in accordance with
M-
MSHA, OSHA and other applicable regulations.
Never substitute, modify, add or omit parts. Use only exact replacement parts in the
N-
configuration as specified by the manufacturer.
Refer to Users Instructions, and/or maintenance manuals for information on use and
O-
maintenance of these respirators.
Some CBRN agents may not present immediate effects from exposure, but can result in delayed
R-
impairment, illness, or death.
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
T-
be followed. If contaminated with liquid chemical warfare agents, dispose of the respirator after
decontamination.
Not for use in atmospheres immediately dangerous to life and health or where hazards have not
V-
been fully characterized.
Use replacement parts in the configuration as specified by the applicable regulations and
W-
guidance.
Consult manufacturer's User Instructions for information on the use, storage, and maintenance
X-
of these respirators at various temperatures.
This respirator provides respiratory protection against inhalation of radiological and nuclear dust
Y- particles. Procedures for monitoring radiation exposure and full radiation protection must be
followed.
If during use, and unexpected hazard is encountered such as a secondary CBRN device;
Z-
pockets of entrapped hazard or any unforeseen hazard, immediately leave the area for clean air.
CC- For entry, do not exceed maximum use concentrations established by regulatory standards.
When used at defined occupational exposure limits, the rated service time cannot be exceeded.
HH- Follow established canister change-out schedules or observe End-Of-Service-Life Indicators to
ensure that canisters are replaced before breakthrough occurs.
Use in conjunction with personal protective ensembles that provide appropriate levels of
QQ- protection against dermal hazard. Failure to do so may result in personal injury even when the
respirator is properly fitted, used, and maintained.
The respirator should not be used beyond eight (8) hours after initial exposure to chemical
UU- warfare agents to avoid possibility of agent permeation. If liquid exposure is encountered, the
respirator should not be used for more than two (2) hours.
