HEADQUARTERS, DEPARTMENT OF THE ARMY. 1 SEPTEMBER 1992. TM 11-5820-890-10-1 . ELECTRICAL SHOCK. SAFETY STEPS. DO NOT TRY TO PULL OR GRAB THE INDIVIDUAL. IF YOU CANNOT TURN OFF THE ELECTRICAL POWER, PULL, PUSH, OR LIFT THE PERSON TO SAFETY USING A DRY WOODEN POLE OR A.

3 DRY ROPE OR SOME OTHER INSULATING MATERIAL. SEND FOR HELP AS SOON AS POSSIBLE. AFTER THE INJURED PERSON IS FREE OF CONTACT WITH THE SOURCE. OF ELECTRICAL SHOCK, MOVE THE PERSON A SHORT DISTANCE AWAY. AND IMMEDIATELY START ARTIFICIAL RESUSCITATION. FOR ARTIFICIAL RESPIRATION, REFER TO FM 21-11. WARNING. RF ENERGY IS PRESENT NEAR THE ANTENNA DURING TRANSMISSION. MAINTAIN. AT LEAST 30 INCHES BETWEEN VEHICULAR ANTENNA AND PERSONNEL DURING. TRANSMISSIONS. WARNING. HIGH VOLTAGE. EXISTS AT CONNECTOR J1 ON VEHICULAR. MOUNTING ADAPTER. AVOID PERSONAL IN- JURY: BE SURE J1 IS COVERED OR CAPPED.

4 WHEN NOT IN USE. DEATH OR SERIOUS INJURY CAN RESULT: When antenna tip caps are not installed on antennas. When a tied-down antenna hits a fixed object such as an overhead bridge, tree limb, etc. Flying antenna parts might strike nearby personnel. A. TM 11-5820-890-10-1 . WARNING. A lithium battery used with your manpack radio contains pressurized sulfur dioxide gas. The gas is toxic, and the battery MUST NOT be abused in any way which may cause the battery to rupture. DC NOT heat, short circuit, crush, puncture, mutilate, or disassemble bat- teries.

5 DO NOT USE any battery which shows signs of damage, such as bulging, swelling, disfigurement, a brown liquid in the plastic wrap, a swollen plastic wrap, etc. DO NOT test lithium batteries for capacity. DO NOT recharge lithium batteries. DO NOT dispose of lithium batteries with ordinary trash/refuse. Turn in dis- charged batteries to local supply. If the battery compartment becomes hot to the touch, if you hear hissing or burping ( , battery venting), or smell irritating gas (sulfur dioxide), IMMEDIATELY TURN OFF the equipment and leave the area. 1.

6 Allow the equipment to cool at least one hour. 2. Remove and replace battery after the equipment has cooled to the touch. 3. If there is a safety incident, or if you believe a safety hazard exists, notify your local Safety Office/Officer, file a Product Quality Deficiency Report, SF Form 368, and notify the CECOM Safety Office, Ft. Monmouth, NJ at AV 995-3112. DO NOT use a Halon type fire extinguisher on a lithium battery fire. In the event of a fire near a lithium battery(ies), rapid cooling of the lithium battery(ies) is important. Flood the equipment with water, or use a carbon dioxide (CO2) extinguisher.

7 Control of the equipment fire, and cooling, may prevent the battery from venting and potentially exposing lithium metal. In the event that lithium metal becomes involved in fire, the use of a graphite based Class D fire extinguisher is recommended. DO NOT store batteries in unused equipment. DC NOT store lithium batteries with other hazardous materials. Keep them away from open flame or heat. B. *TM 11-5820-890-10-1 . TECHNICAL MANUAL HEADQUARTERS. DEPARTMENT OF THE ARMY.
