CARBON MONOXIDE (EXHAUST GAS) CAN CAUSE DEATH
Carbon monoxide is without color or smell, but can cause death. Breathing air with
carbon monoxide produces symptoms of headache, dizziness, loss of muscular
control, a sleepy feeling, and coma. Brain damage or death can result from heavy
exposure. Carbon monoxide occurs in the exhaust fumes of fuel-burning heaters
and internal combustion engines. Carbon monoxide can become dangerously
concentrated under conditions of no ventilation. Precautions must be followed to
ensure crew safety when the personnel heater or engine of any vehicle is operated
for any purpose.
CAUTION
Water pump is constantly engaged and operates whenever water pump engine is
running. At least one water inlet valve must be opened whenever water pump
engine is running. A pressure reading on PUMP DISCHARGE gauge (with engine
running) indicates adequate water supply to water pump for cooling. Failure to
comply may result in water pump overheating and will cause damage to equipment.
Water pump must be primed when operating water pump engine. Failure to prime
water pump when operating water pump engine will cause damage to equipment.
Step 1.
Turn battery disconnect switch to ON position (WP 0007). Pump from onboard water
tank (WP 0026). Using pump operator's panel PUMP DISCHARGE gauge, check if
water pump output pressure is low.
If water pump output is not low, fault corrected.
Step 2.
Put TANK TO PUMP switch to CLOSED position (WP 0004). Pump from hydrant or in
relay (WP 0027). Using pump operator's panel PUMP DISCHARGE gauge, check if
water pump output pressure is low.
If water pump output is not low, troubleshoot Tank-To-Pump Valve(s) Does
Not Operate Properly (WP 0119).
