The detection of trace gas amounts will not cause
the buzzer alarm to sound.
If ambient gas levels return to normal, the yellow
’Trace Gas’ LED will go out and the green ’Systems
Normal’ LED will illuminate.
What To Do When Trace Gas Levels Are
Detected
Look in the mirrors for evidence of white smoke
escaping from behind the cab or from the batteries.
If there is smoke:
•
Pull over into a safe location as soon as
possible.
•
Turn off the ignition, set the park brake, press
the eStop button, and exit the vehicle.
•
Move a safe distance from the vehicle, fifty to
one hundred feet if possible. Avoid inhaling the
smoke. When in a safe location, call
emergency services.
NOTICE
If possible, set out reflectors or flares to keep
other people and vehicles at a safe distance and
to guide them around the vehicle.
If the alarm is false, do not consider the area
clear until emergency responders have declared
the area safe, all alarm indicators are OFF, and
the alarm panel light illuminates green.
If smoke or flames are coming from a high
voltage battery, trained emergency responders
should use large amounts of water to cool the
battery. Battery fires can take up to 24 hours to
extinguish. Emergency responders should
consider allowing the battery to burn in place.
Do not tow a vehicle until all fires have been
extinguished and the high-voltage batteries are
no longer giving off heat. After a fire, do not
store a towed vehicle indoors.
If there is no smoke:
•
Pull over into a safe location
•
Turn off the ignition, set the park brake, and
exit the vehicle.
•
If applicable, call a supervisor for assistance.
•
Observe the vehicle for fifteen minutes.
•
If you observe smoke, move a safe distance
from the vehicle, fifty to one hundred feet if
possible. Avoid inhaling the smoke. When in a
safe location, call emergency services.
•
If no smoke is observed after fifteen minutes,
enter the truck and check for high-voltage or
battery faults and warnings.
If faults are active HV related fault codes that
prevent High Voltage from energizing, contact
a supervisor. If there are HV related fault
codes, but HV is energized and truck is able to
drive, follow the information displayed on the
instrumentation cluster or B-panel (most likely
drive to nearest service center).
If no faults are present, drive the vehicle to the
nearest service center. The vehicle should not
be in operation until the problem is diagnosed
and resolved.
Significant Gas Levels Detected
WARNING
Immediately bring the vehicle to a safe stop when
the buzzer alarm sounds and the lower red
’Significant’ LED illuminates. Apply the park
brake, turn off the ignition, press the eStop
button, and get clear of the vehicle.
Waiting to see if the upper red ’Significant’ LED
illuminates after one minute could result in
severe personal injury or death.
WARNING
If outside the vehicle when the alarm buzzer
sounds, do not attempt to open or enter the cab
to retrieve items, turn off the ignition, or hit the
eStop button; doing so could result in severe
personal injury or death.
NOTE: The green ’Systems Normal’ light is
extinguished when the red ’Significant’ LED
illuminates. This does not indicate that the
system has lost power or is not operating
normally.
If gas concentrations increase to the 50% LEL for
that gas, and maintain or exceed that level for six
continuous seconds, the lower red ’Significant’ LED
illuminates and the buzzer alarm activates and emits
a continuous alarm.
