WARNING

When operating the Concrete-Mobile

mixer body, be sure to observe all warnings identified in

the TM-9-2320-273-10, Operator’s Manual for the M919 truck chassis.

The warning conditions

most likely to be encountered during concrete mixing operations are repeated here.

CARBON MONOXIDE POISONING CAN BE DEADLY

Carbon monoxide is a colorless, odorless, 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

muscular control, apparent drowsiness, or coma. Permanent brain damage can result from severe exposure.

Carbon monoxide occurs in the exhaust fumes of fuel-burning internal combustion engines and can become dangerous

under conditions of inadequate ventilation. The following precautions must be observed to insure the safety of personnel:

A. DO NOT operate the engine of a vehicle in an enclosed area unless it is ADEQUATELY VENTILATED.

B. DO NOT idle the engine for long periods without maintaining ADEQUATE VENTILATION in the personnel

compartments and immediate area.

C. DO NOT operate any vehicle with inspection plates, cover plates, or engine compartment doors removed

unless it is necessary for maintenance purpose.

D. BE ALERT at all times during vehicle operation for exhaust odors, and exposure symptoms.

If either is

present, IMMEDIATELY VENTILATE the area. If symptoms persist, remove affected personnel from the

area and treat as follows.

(1) Expose to fresh air.

(2) Keep warm.

(3) DO NOT PERMIT EXERCISE.

(4) If necessary, administer artificial respiration.

THE BEST DEFENSE AGAINST CARBON MONOXIDE POISONING IS ADEQUATE VENTILATION.
