22、ORTH Brigadier General, United States Army The Adjutant General DISTRIBUTION: To be distributed in accordance with DA Form 12-51 Operator and Unit requirements for AN/PRC-77. TM 11-5620-667-12 WARNING Adequate ventilation should be provided while using TRICHLOROTRIFLUOROETHANE. Avoid prolonged breat
23、hing of vapor. The solvent should not be used near heat or flame; the products of de- composition arc toxic and irritating. Since TRICHLOROTRIFLUOROETHANE diSSOlVeS natural oils, avoid prolonged contact with skin. The usc of chemical gloves (solvent resistant), chemical splash goggles and full faces
24、hield are required when using TRICHLOROTRIFLUOROETHANE. DO NOT use compressed air to dry parts when TRICHLOROTRIFLUOROETHANE has been used. TRICHLOROTRIFLUOROETHANE is an ozone-depleting substance. Lithium sulfur dioxide (Li-SO2) batteries used with this equipment contain pressurized sulfur dioxide
25、SO2 gas. Sulfur dioxide gas is toxic; do not abuse the battery in any way which might cause it to rupture. DO NOT heat, incinerate, short circuit, crush, puncture, mutilate or disassemble any battery. DO NOT use any battery which shows signs of damage, such as bulging, swelling, disfigure- ment, swo
26、llen plastic wrap, liquid in the plastic wrap, etc. IMMEDIATELY turn off the equipment if the battery compartment becomes hot to the touch. Let the battery cool at least 60 minutes before removing it. If you hear a hissing sound (battery venting) or smell irritating sulfur dioxide gas, remove the eq
27、uipment to a well- ventilated area or leave the area. DO NOT use equipment if the battery compartment shows signs of water leakage. DO NOT use water to put out a fire if a shock hazard exists (i.e., 30 or more volts). DO NOT use a HALON fire extinguisher on a lithium battery fire. Use an approved Cl
28、ass-D fire extinguisher such as Lith-X. DO NOT test lithium batteries for capacity with Test Set, AN/PSM-13 and Connector, Adapter, U-410; this equipment is inaccurate for lithium batteries and may cause the battery to vent. DO NOT recharge any primary lithium or magnesium battery. DO NOT smoke or u
29、se an open flame in battery storage areas. DO NOT dispose of lithium batteries in streams, rivers, oceans, with general refuse or trash, etc. Lithium batteries without a discharge switch shall be turned into the Defense Reutiliza- tion and Marketing Office (DRMO) for disposal. Dispose of magnesium b
30、atteries as generated; turn into DRMO only if damaged or quantity to be disposed of exceeds 500 pounds at one time. For additional information on battery disposal contact your local CECOM LAO/LAR for CECOM Safety Office Battery Disposition/Disposal Handbook dated November 1986. DO NOT seal magnesium
31、 batteries in gas-tight plastic bags, drums or any other non-vented container. Depleted magnesium batteries continue to generate hydrogen gas after use, which can cause an explosion if it accumulates in a confined area. DO NOT leave batteries in unused equipment more than 30 days. This helps insure
32、that dangerous gases do not accumulate. Accumulated gases can cause explosions which can injure personnel and damage the equipment. PREVENT personal injury when applying or removing steel strapping by wearing heavy gloves and a face shelf. DO NOT handle packing cartons by steel strapping. Change 2A
