WARNING
ICON 68,66,30
Do not touch extremely cold metal below -26F (-32C). Bare skin may freeze to cold
metal and cause injury to personnel.
All valves should be opened and closed slowly during any procedure. Sudden
changes in pressure may cause equipment to react faster than personnel can be
alerted. Make sure surrounding personnel are aware of changes being made to
settings on equipment. Failure to comply may result in injury or death to personnel
and damage to equipment.
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.
DO NOT operate personnel heater or engine of vehicle in a closed place without
proper ventilation.
DO NOT drive any vehicle with inspection plates, cover plates, or engine
compartment covers removed unless necessary for maintenance purposes.
BE ALERT at all times during vehicle operation for exhaust odors and exposure
symptoms. If either are present, IMMEDIATELY VENTILATE personnel
compartments. If symptoms persist, remove affected crew to fresh air and keep
warm. DO NOT PERMIT PHYSICAL EXERCISE. If necessary, give artificial
respiration and get immediate medical attention. For artificial respiration, refer to
FM 4-25.11.
BE AWARE that the gas particulate filter unit or field protection mask for nuclear-
biological-chemical protection WILL NOT offer safety from carbon monoxide
poisoning.
THE BEST DEFENSE AGAINST CARBON MONOXIDE POISONING IS GOOD
VENTILATION.
