WARNING

CARBON MONOXIDE

Carbon monoxide is colorless, odorless, DEADLY POISONOUS gas which, when breathed, deprives the

body of oxygen and causes SUFFOCATION. Exposure to air contaminated with carbon monoxide pro-

duces symptoms of headache, dizziness, loss of muscular control, apparent drowsiness, or coma. Permanent

BRAIN DAMAGE or DEATH can result from severe exposure.

Carbon monoxide occurs in the exhaust fumes of fuel-burning heaters and internal-combustion engines and

becomes DANGEROUSLY CONCENTRATED under conditions of INADEQUATE VENTILATION. The

following precautions MUST be observed to insure the safety of personnel whenever the engine is operated

for maintenance purposes.

DO NOT operate the engine in an enclosed area unless it is ADEQUATELY VENTILATED.

DO NOT operate the engine in an enclosed area such as a test cell without properly fitted and func-

tioning exhaust ducts.

BE ALERT at all times during engine operation for exhaust odors and exposure symptoms. If either

are present, IMMEDIATELY VENTILATE the work area. If symptoms persist, remove affected person-

nel from the work area and treat as follows: expose to fresh air; keep warm; DO NOT PERMIT PHYSl-

CAL EXERCISE; if necessary, administer artificial respiration as described in FM 21-11.

WARNING

HANDLING WEIGHTS

This manual considers short-term, non-repetitive lifts of equipment weighting up to 190 pounds to heights

of about 3 feet. Under these conditions, this manual assigns one man for each 47-pound increment of

weight up to a total of four men to accomplish the required lifts. If local conditions mandate higher lifts,

repetitive lifts, or carries greater than 9 feet, refer to MlL-STD-1472 for a guideline on the number of

personnel needed.
