immediately remove the device from service. The FireHawk M7
HUD or I-HUD, FireHawk M7XT Control Module, and FireHawk
M7XT Power Module are approved intrinsically-safe and con-
form to UL/ANSI 913 for use in Class I, Div. I, Groups C and D haz-
ardous locations, temperature rating T1.
Use the air mask with adequate skin protection when worn in
gases and vapors that poison by skin absorption (for example:
hydrocyanic-acid gas). In making renewals or repairs, parts iden-
tical with those furnished by the manufacturer under the perti-
nent approval shall be maintained.
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 10145467).
Do not mark the air mask, i.e., with stamps, labels, paint, or
other method. Use of such markings may interfere with appa-
ratus use or may constitute a flammability hazard.
For more information on the air mask use and performance
standards, please consult the following publications:

NOTE: The FireHawk M7 HUD or I-HUD, FireHawk M7XT
Control Module, and FireHawk M7XT Power Module, were
tested and found to comply with the limits for a Class B digital
device, pursuant to Part 15 of the FCC Rules. These limits are
designed to provide reasonable protection against harmful
interference in a residential installation. This equipment gener-
ates, uses, and can radiate radio frequency and, if not installed
in accordance with instructions, may cause harmful interfer-
ence to radio communications. However, there is no guarantee
that interference will not occur in a particular installation. If
this equipment does cause interference to radio or television
reception, which can be determined by turning the equipment
off and on, the user is encouraged to try to correct the interfer-
ence by one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and the
receiver.
• Connect the equipment into an outlet on a circuit different
from that to which the receiver is connected.
• Consult the dealer or an experienced radio/TV technician
for help.
The FireHawk M7 HUD or I-HUD, FireHawk M7XT Control
Module, and FireHawk M7XT Power Module contain electri-
cal parts which have not been evaluated as an ignition
source in flammable or explosive atmospheres by
MSHA/NIOSH.
1. Read and follow all NIOSH and other approval
limitations.
2. DO NOT use the carrier and harness assembly as a verti-
cal raising or lowering device.
3. DO NOT use the air mask as an underwater device.
4. This system must be supplied with respirable [Quality
Verification Level (Grade) D, see ANSI/CGA G-7.1-1989]
or higher quality air; and a dew point not to exceed -
65°F (24ppm v/v) [Compressed Gas Association
Specification G-7.1 for Quality Verification Level (Grade)
D Gaseous Air]. In fire service applications, MSA recom-
mends breathing air quality in accordance with NFPA
1989.
5. This device may not seal properly with your face if you
have a beard, gross sideburns or similar physical charac-
teristics (see NFPA-1500 and ANSI Z88.2). An improper
facial seal may allow contaminants to leak into the face-
piece, reducing or eliminating respiratory protection. Do
not use this device if such conditions exist. The face-to-
facepiece seal must be tested before each use. Never
remove the facepiece except in a safe, non-hazardous,
non-toxic atmosphere.
6. Return to a safe atmosphere immediately if
discoloration, crazing, blistering, cracking, or other
deterioration of the facepiece lens material is observed.
7. Users must wear suitable protective clothing and
precautions must be taken so that the air mask is not
exposed to atmospheres that may be harmful to it.
8. Take into account the following factors which may affect
the duration or the service time.
a. the degree of physical activity of the user;
b. the physical condition of the user;
c. the degree that the user's breathing rate is increased
by excitement, fear, or other emotional factors;
d. the degree of training or experience which the user
has had with this or similar equipment;
e. whether or not the cylinder is fully charged;
f. the presence in the compressed air of carbon dioxide
concentrations greater than the .04% level normally
found in atmospheric air;
g. the atmospheric pressure; if used in a pressurized tun-
nel or caisson at 2 atmospheres (15 psi gauge) the
duration will be one-half as long as when used at 1
atmosphere; at 3 atmospheres the duration will be
one-third as long; the service time of the air mask is
based on 1 atmosphere of pressure.
h. the condition of the air mask.
