SECTION IV. OPERATION UNDER UNUSUAL CONDITIONS

TM 5-3610-295-13&P-2 SECTION IV. OPERATION UNDER UNUSUAL CONDITIONS 2-11. OPERATION UNDER UNUSUAL CONDITIONS. Some of the unusual conditions that may be encountered are extreme cold, extreme heat, dust or sand, and rain or high humidity. WARNING In extreme cold, do not touch metal parts with bare hands. Severe skin damage may result. a. Operation in Extreme Cold. The operation of the internal equipment is performed within environmentally controlled conditions; however, the main power cable and grounding cable in extreme cold will be hard, brittle and difficult to handle. Be careful when handling or connecting the cables to the shelter so that kinks and unnecessary loops will not result in permanent damage. Make certain that connections and cable receptacles on the outside of the shelter are free of frost, snow, and ice. When shelter heaters are not operating or when the shelter is being transported, liquid consumable supplies may freeze, break their containers, and then melt and ruin equipment or documents. Remove all liquids from shelter when heaters are not operating. b. Operation in Extreme Heat. The operation of the internal equipment is performed within the environmentally controlled conditions; however, during transportation or when air-conditioning units are not operating, consumable supplies may suffer reduced shelf-life, and internal components may have accelerated deterioration of gaskets, seals, or insulation. Frequently inspect gaskets, seals, and insulation for deterioration. c. Operation in Tropical Conditions. Fungi, mildew or mold will form on and in equipment, documents, and supplies if internal environment is not operating and outside heat and humidity are allowed to enter the shelter. Inspect equipment, documents, and supplies frequently for signs of fungi, mildew, or mold. d. Operation in Desert Conditions. Dust, grit and sand will ruin supplies, equipment, and documents. Use extreme care to prevent dust, grit, and sand from getting into the shelter. Air filters will be changed whenever air flow is restricted and vacuuming of shelter interior must be conducted more frequently than specified by PMCS schedules. 2-21/(2-22 Blank)
