Section IV. OPERATION UNDER UNUSUAL CONDITIONS
2-10. GENERAL. This section contains instructions for operation of the MFK in unusual environmental conditions of
extreme cold, extreme heat, dusty or sandy areas, rainy and humid conditions, salt water areas, high altitudes, and under
windy conditions. Refer to TM 10-7360-204-1 3&P, for M2 burner unit operation under unusual conditions.
2-11. OPERATION IN EXTREME COLD (BELOW 0°F/-18°C).
CARBON MONOXIDE GAS CAN KILL YOU.
THE BEST DEFENSE AGAINST CARBON MONOXIDE POISONING IS
Carbon monoxide gas is not visible and has no smell, but it can kill you. 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 exhaust fumes of fuel-burning
equipment such as the M2 burner units. Carbon monoxide can become dangerously
concentrated under conditions of no air movement. Precautions must be followed to
ensure safety of personnel when you operate the M2 burner units. Open vents in the
tent to provide ventilation and prevent the accumulation of carbon monoxide gas.
Be ALERT at all times during MFK operation for symptoms of carbon monoxide
exposure. IMMEDIATELY VENTILATE the tent. If symptoms persist, move
affected personnel to fresh air and keep warm. DO NOT PERMIT PHYSICAL
EXERCISE. If necessary. give artificial respiration.
Operators be aware of signs of dangerous combustion products. Report any signs of
headache, distress, dizziness, nausea and weakness.
FOR ARTIFICIAL RESPIRATION REFER TO FM 21-11.
Do not touch the MFK equipment metal parts when temperatures are below freezing
without gloves, as injury may result.
Wear protective clothing to prevent cold injuries.
In extreme cold allow a longer period of time than normal to
heat water to the desired temperature.
Operate the M2 burner units in extreme cold conditions in accordance with TM 10-7360-204-13&P.
Vent tent as often as possible. It is best to leave doors, windows, and roof vents open slightly. If this is not
possible, open doors and roof vents periodically to remove stuffiness. At high altitudes do this more often. Operators
should periodically leave the tent for a brief time.
If eye, nose or throat irritation is noted vent the tent and adjust burners in accordance with TM 10-7360-204-13&P
to obtain a greenish-colored flame.
To reduce the environmental effects of extreme cold, use of the cold weather components shown in Appendix D,
