1 Safety Regulations
This SCBA complies with the National Institute for Occupational Safety and Healthy (NIOSH) regula-
tion under 42 CFR Part 84 for open circuit self-contained breathing apparatus, the National Fire
Protection Association (NFPA) Standard 1981 on Open-Circuit Self-Contained Breathing Apparatus
(SCBA) for Emergency Services and the NFPA Standard 1982 on Personal Alert Safety Systems
(PASS).
1.1 NIOSH Approval Information
This pressure-demand, self-contained breathing apparatus (SCBA) is certified by the National Insti-
tute for Occupational Safety and Health (NIOSH) for use in atmospheres immediately dangerous to
life or health (IDLH):
“Immediately dangerous to life or health” means conditions that pose an immediate threat to life or
health or conditions that pose immediate threat of severe exposure to contaminants, such as radio-
active materials, which are likely to have adverse cumulative or delayed effects on health
[Title 42 CFR, Part 84.2, (Q)].

NIOSH Cautions and Limitations
NIOSH S - Special or Critical User’s Instructions
-Approved for use at temperatures above -25°F (- 32°C).
-Approvedonlywhenthecompressed-aircylinderis fullychargedwithair meetingtherequirements
of the Compressed Gas Association Specification G-7 for quality verification level (grade) D air or
equivalent specifications.
-Infireservice applications,MSArecommendsbreathingairqualityinaccordancewithNFPA 1989.
The cylinder shall meet applicable DOT specifications.
-Do not alter this SCBA. Altering will void the Intrinsic Safety rating and may affect the Intrinsic
Safety of the device. Misuse or abuse of the heads-up display (HUD), control module, power
module or speaker module or using this equipment in a manner or situation not intended by the
manufacturer, may result in damage to the HUD, control, power, or speaker module, may result in
personal injury or death to user or persons dependent on the user. Always inspect the HUD,
control, power, and speaker module for damage before use. If damage is found, immediately
remove the device from service. The HUD, control, power, and speaker module are approved
WARNING
Read and follow all NIOSH approval limitations. Misuse can result in serious injury or death.
J- Failure to properly use and maintain this product could result in injury or death.
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 specified by the manufacturer.
O- Referto UsersInstructions,and/or maintenancemanualsforinformation onuseand maintenance
of these respirators.
S- Special or critical User’s Instructions and/or specific use limitations apply. Refer to user instruc-
tions before donning.

intrinsically-safe and conform to UL 913 6th edition, Class I, Division 1, Groups C and D, Temper-
ature Rating T1..
-Use the SCBA with adequate skin protection when worn in gases and vapors that poison by skin
absorption (for example: hydrocyanic-acid gas).
-Approval for use against CBRN chemical warfare agents is maintained only when using approved
components and following instructions listed on the NIOSH approval matrix
(P/N 10158405).
-For non-CBRN applications see Approval Insert (P/N 10154623).
-Do not mark the SCBA, i.e., with stamps, labels, paint, or othermethod. Use of such markings may
interfere with apparatus use or may constitute a flammability hazard.
Cautions And Limitations Of Emergency Breathing Support Systems (EBSS)
-Activation or engagement of EBSS in either the donor or receiver mode changes the SCBA use to
Escape-Only, approved service time for either the donor, or the receiver is no longer applicable.
-EBSS may not be engaged or activated in donor mode after the donor End-of-Service-Time-Indi-
cator (EOSTI) has activated.
-Users must be fully trained in the operation of EBSS in accordance with a training program
conforming to the requirements of NFPA Standards 1404, Fire Service Respiratory Protection
Training and 1500, Fire Department Occupational Safety and Health Program.
-Simultaneous connection of more than two users, one donor and one receiver, is not permitted.
SCBAs operated in EBSS mode are approved for escape only.
-Entry approval only restored after re-charge, either host or donor.
-Connection not to be established after donor/host EOSTI activation.
-Limited to one donor/receiver (host/parasite) pair. Not suitable for connection in CBRN environ-
ment.
1.2 NIOSH CBRN Approval Information
This SCBA has been designated by NIOSH as being CBRN (chemical, biological, radiological, and
nuclear) Agent Approved. It complies with the special tests under NIOSH 42 CFR 84.63(c); Chemical
Agent Permeation and Penetration Resistance Against Distilled Sulfur Mustard (HD) and Sarin (GB)
and the Laboratory Respirator Protection Level (LRPL) tests.
DANGER
Use in conjunction with personal protective ensembles that provide appropriate levels of protection
against dermal hazards.
Some CBRN agents may not present immediate effects from exposure, but can result in delayed
impairment, illness, or death.
Direct contact with CBRN agents requires proper handlingof the SCBA 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 SCBA after decontamination.
The respirator should not be used beyond 6 hours after initial exposure to chemical warfare agents
to avoid possibility of agent permeation.
FAILURE TO FOLLOW THE ABOVE ITEMS IN ADDITION TO ALL ESTABLISHED CBRN
PROTECTIVE MEASURES CAN RESULT IN SERIOUS PERSONAL INJURY OR DEATH.

1.3 NFPA Approval Information
The MSA G1 SCBA meets the requirements of the National Fire Protection Association (NFPA) 1981
(2013 edition) Standard on Open-Circuit Self-Contained Breathing Apparatus (SCBA) for Emergency
Services when configured in accordance with the NFPA approval. When the SCBA is equipped with
a power and control module, the SCBA meets the requirements of the NFPA 1982 (2013 edition)
Standard on Personal Alert Safety Systems (PASS) when configured in accordance with the NFPA
approval. The MSA G1 SCBA must be used in accordance with NFPA 1500 Standard on Fire Depart-
ment Occupational Safety and Health Program to maintain NFPA 1981.
The certification agency for NFPA compliant SCBA used by MSA is Safety Equipment Institute (SEI).
SEI can be contacted for clarification on your NFPA compliant version of this SCBA or to report any
operational malfunction.
