Second Stage Regulator - Honeywell TITAN SCBA Operation Manual

b. Prior to donning the facepiece in cold weather,
visually inspect the lens, AIR KLIC, and exhalation
valve for ice.
c. If ice is present, warm the facepiece to melt the ice.
Ice may be melted by placing the facepiece inside
outerwear near the body to warm.
NOTE
If the facepiece has been stored at a
temperature below freezing (32°F or 0°C) and
it is not possible to warm the facepiece prior to
usage, do not exhale into the facepiece until it
is properly donned and the regulator is installed
and activated.
d. Check the function of the exhalation valve by
performing a positive pressure exhalation test and
negative pressure leak check as follows:
e. Don the facepiece as specifi ed in the Donning sec-
tion of this manual.
f. Perform a negative pressure leak check:
i. Place your hand over the AIR KLIC.
ii. Inhale and hold your breath for a few seconds.
The facepiece should collapse on your face and
remain collapsed for several seconds without leak-
ing.
iii. If the facepiece leaks, exhale onto the exhala-
tion valve at least six to eight more times. Reposi-
tion the facepiece, check the straps, and repeat
the leak check.
iv. If the facepiece continues to leak, remove it
from service.
v. Have the facepiece inspected and/or repaired
by a Honeywell-certifi ed repair technician before
reuse.
g. Perform a positive pressure exhalation test:
i. Take a deep breath, and place your hand over
the AIR KLIC.
ii. Exhale normally. The exhalation valve must
function normally.
iii. If the exhalation valve does not function or if it
is diffi cult to exhale, remove the facepiece.
iv. Reposition the facepiece, check the straps, and
repeat the test.
v. If the exhalation valve continues to malfunction,
remove the facepiece from service.
vi. Have the facepiece inspected and/or repaired
by a Honeywell-certifi ed repair technician before
reuse.
h. Again, visually check to verify that the facepiece,
lens, AIR KLIC, and exhalation valve are ice-free.
WARNING
If it becomes necessary to remove the
facepiece when using the SCBA, move to a
non-hazardous area fi rst. Failure to comply
with this warning may lead to personal
injury, illness, or death.

NOTE
If the ambient temperature is near or below
freezing, place the facepiece and regulator
under outerwear to keep it warm in case reuse
is necessary.

3. Second Stage Regulator

WARNING
• Ice on the second stage regulator AIR KLIC
buttons or the facepiece AIR KLIC adapter
may prevent proper engagement and/or
disengagement of the regulator.
• The user must ensure that the regulator is
properly engaged by tugging the regulator to
verify that both release buttons are properly
engaged in the AIR KLIC.
• When using the SCBA in temperatures
below 0°F (-17.78°C), press the manual
activation button on the front of the regulator
to activate fl ow immediately after inserting
the regulator.
• Failure to comply with this warning may
lead to personal injury, illness, or death.
a. The second stage regulator must be protected
from moisture during cold weather conditions to avoid
ice buildup on its exterior surfaces. Ice can interfere
with emergency bypass operation or AIR KLIC button
function, which can hinder regulator removal from the
facepiece or from the regulator receiver.
b. Visually inspect the external surfaces of the regula-
tor for ice prior to use.
c. If ice is present, it may be melted by placing the
regulator inside outerwear near the body to warm.
d. Again, visually inspect the regulator for ice, then
check the red bypass knob and the AIR KLIC buttons
for proper function.
e. Should ice form on the regulator while the regulator
is in the facepiece, it will continue to function properly.
When it becomes necessary to remove the regulator,
tug the regulator to break off the ice, then remove the
regulator from the facepiece.
f. If the AIR KLIC buttons are frozen and the regulator
cannot be removed, do not force the buttons. Move to
a non-hazardous area, depress the regulator shutoff
button, and remove the facepiece and regulator as a
unit.
g. If the shutoff button is nonfunctional, turn off the air
supply at the cylinder valve.
h. Remove the facepiece and regulator as a unit.
i. Warm the facepiece and regulator until the normal
function of the AIR KLIC button and/or the shutoff but-
ton returns.
j. Should ice form on the regulator while the regulator
is in the waist strap-mounted regulator holder, rotate
the regulator to break off the ice, then remove the
regulator from the regulator holder.
