HEADQUARTERS, DEPARTMENT OF THE ARMY OCTOBER 1974 TM 55-1905-217-34 WARNING DANGEROUS CHEMICALS are used in this equipment. SERIOUS INJURY OR DEATH may result if personnel fail to observe these safety precautions. Avoid contact with the battery electrolyte. If the solution comes in contact with the skin, rinse the area immediately with clear water to avoid skin burns. Be sure all cargo is secure, especially during rough seas. WARNING FIRE OR EXPLOSION HAZARD SERIOUS INJURY OR DEATH may result if personnel fail to observe these safety precautions. Hatches must be open before energizing any electrical circuits or starting engines. Do not smoke or use an open flame in the vicinity when servicing batteries as hydrogen gas, an explosive is generated. Use only distilled water to maintain battery electrolyte level. Do not fill fuel tank while engine is running. Provide metallic contact between the fuel container and fuel tank to prevent a static spark from igniting fuel. Wipe or flush any spillage. Volatile materials will not be brought aboard; electrical circuits will not be energized; fuel tanks will not be topped off; and engines will not be started before CO2 fire fighting equipment is available and operative. Observe NO SMOKING rules when refueling. Do not work on live circuits. Tag circuit and warn other personnel not to energize the circuit. Never use a blow torch or other similar means for heating fuel or oil lines. WARNING ASPHYXIATION DANGER Be sure engine room ventilators are open when operating the engine(s). The engine exhaust gases contain carbon monoxide which is a colorless, odorless, and poisonous gas.

PENNINGTON Major General, United States Army The Adjutant General Distribution: To be distributed in accordance with DA Form 12-25D, Direct and General Support maintenance requirements for Marine Equipment: ALL. TM 55-1905-217-34 SERIOUS INJURY OR DEATH may result if personnel fail to observe these safety precautions. Avoid contact with the battery electrolyte. If the solution comes in contact with the skin, rinse the area immediately with clear water to avoid skin burns. Acids can cause serious burns or blindness. Avoid contact with eyes, skin, or clothing. Do not breathe vapors. Wear rubber gloves, goggles, and a rubber apron when handling them. When diluting acids, do not add water to acid; the acid must be added to the mixture slowly and with constant mixing. In case of contact with acid, flush the affected area with plenty of water and obtain medical aid immediately. Before working on any electrical equipment, make sure the circuits has been deenergized and the cables have been disconnected from the battery. When cutting with a torch, or when welding, always station fire watches, ready with fire extinguishers, in the vicinity on both sides of the plate that is being cut or welded. Ramp hinge pins must be replaced one at a time, allowing three remailing pins to support ramp. Removal of two or more hinge pins may result in the weight of the ramp misaligning the remaining hinges, resulting in damage to ramp and possible injury or death to maintenance personnel. When refueling, shut down the electrical system of the LARC. Observe the no smoking rule. Do not permit anyone to operate tools or equipment which may produce sparks near the refueling operation. Sparks or fire may ignite the diesel fuel and produce an explosion. Before attempting to remove any compressed air system lines or components, relieve air pressure from system. Failure to do so may result in injury or possible death to maintenance personnel. Before disconnecting a line in the hydraulic system, bleed the pressure from that portion of the line. Failure to do so may result in injury or possible death to maintenance personnel. Be sure all cargo is secure, especially during rough seas. WARNING FIRE OR EXPLOSION HAZARD SERIOUS INJURY OR DEATH may result if personnel fail to observe these safety precautions. Hatches must be open before energizing any electrical circuits or starting engines. Do not smoke or use an open flame in the vicinity when servicing batteries as hydrogen gas, an explosive is generated. Use distilled water to maintain battery electrolyte level. Do not fill fuel tank while engine is running. Provide metallic contact between the fuel tank to prevent a static spark from igniting fuel. Fuel oil and other petroleum products are highly volatile in extreme heat. To minimize the possibility of explosion, wipe up all spills at once, see that fuel lines and valves are not leaking and pump bilges regularly. Change 2 a TM 55-1905-217-34 Volatile materials will not be brought aboard; electrical circuits will not be energized; fuel tanks will not be topped off; and engines will not be started before CO2 fire fighting equipment is available and operative. Observe NO SMOKING rules when refueling. Do not work on live circuits. Tag circuit and warn other personnel not to energize the circuit. Never use a blow torch or other similar means for heating fuel or oil lines. Prior to cutting or welding on the ramp, remove drain plugs on both sides of the ramp and check if ramp interior is primer coated. If primer coated, flush thoroughly with steam, carbon dioxide, or water. Do not reinstall drain plugs until the cutting and/or welding operation is completed. Failure to take this precaution may result in explosion of accumulated primer vapors. WARNING ASPHYXIATION DANGER Be sure engine room ventilators are open when operating the engine(s). The engine exhaust gases contain carbon monoxide, which is a colorless, odorless, and poisonous gas. When working inside the hydraulic oil supply tank, a portable-type circulating blower should be used to prevent vapor accumulation. For extended work periods inside the tank, an air line tube respirator should be worn. Station an observer outside tank in case worker is overcome by fumes.
