Section IV. OPERATION UNDER UNUSUAL CONDITIONS
2-9. GENERAL This section contains instructions for operation of the FSC 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 10-7360-204-13&P for M2 burner unit operation under unusual conditions or TM
10-7310-281-13&P for MBU.
2-10. OPERATION IN EXTREME COLD (BELOW 0°F/-18°C).
§ CARBON MONOXIDE GAS CAN KILL YOU.
§ 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 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 burner units. Open vents in the tent to provide ventilation and prevent the
accumulation of carbon monoxide gas.
§ Be ALERT at all times during FSC operation for symptoms of 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.
§ FOR ARTIFICIAL RESPIRATION REFER TO FM 21-11.
§ THE BEST DEFENSE AGAINST CARBON MONOXIDE POISONING
IS GOOD VENTILATION.
§ Operators be aware of signs of dangerous combustion products. Report any signs
of headache, distress, dizziness, nausea and weakness.
§ Do not touch the FSC equipment metal parts when temperatures are below freezing
without gloves, as injury may result.
In extreme cold allow a longer period of time than normal to heat water to the desired
a. Operate the burner units in extreme cold conditions IAW TM 10-7360-204-13&Pfor the M2 and TM 10-7310-
281-13&P for the MBU.
b. 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.
c. If any eye, nose, or throat irritation is noted vent the tent and adjust burners IAW the appropriate burner TM to
obtain a clean flame.
d. To reduce the environmental effects of extreme cold, use of the cold weather components shown in Appendix
D, is recommended.
