TEST SYSTEM
WARNING
Touching exhaust system during test can cause severe burns. Carbon monoxide is a
colorless, odorless, deadly poisonous gas which, when breathed, deprives the body of
oxygen and causes suffocation. Exposure to air contaminated with carbon monoxide
produces symptoms of headache, dizziness, loss of muscle control, or apparent
drowsiness. Coma, permanent brain damage, or death can result from severe
exposure.
Carbon monoxide occurs in the exhaust fumes of internal combustion engines and
becomes dangerously concentrated under conditions of inadequate ventilation.
Observe the following safety precautions whenever the engine is running:
Operate engine in a ventilated area only.
Do not idle the engine for long periods without maintaining adequate ventilation.
Be alert at all times for exhaust odors and exposure symptoms.
Be aware: the field protective mask for chemical biological radiological (CBR)
protection will not protect you from carbon monoxide poisoning.
Expose victims to fresh air, keep warm, and do not permit physical exercise. For
artificial respiration, refer to FM 21-11. Seek medical attention. Administer oxygen, if
available.
GOOD VENTILATION IS THE BEST DEFENSE AGAINST
EXHAUST POISONING.
Priming discharge mixture of water and exhaust gases may cause severe burns or
injury. Wear gloves and safety glasses when priming pump.
Stand clear of venturi during priming.
CAUTION
Prime the centrifugal pump as soon as possible after engine starts. Rotation of
impeller without water in volute will damage pump components.
