Approach Areas. Do not get within 460 m (1500 ft.) from the side or within 15 m (50 ft.) from the front, rear, or above a tire.
Do not go near any tire on the machine if there is a brake fire, burning rubber or other indications that the brakes have caused too much heat. This heat can have an effect on all other tires on the machine, even though the visual indication is only at one tire.If there is an indication of a brake fire or the smell of burning rubber, do not go near the machine. Fight (put out) these fires from a remote location. (Many times, the immediate action to a fire caused by tires or brakes, is for people to use a hand fire extinguisher and run up close to the machine to help put out the fire.) Keep away from the machine until the tires cool (temperature decreases). Permit at least eight hours for the tires to cool before a person goes near the machine.Keep personnel out of the area, and at least 460 m (1500 ft.) away from the side of the tire and 15 m (50 ft.) away from the front or rear of the machine.A small fire caused by debris on the machine is not a hazard. This type of fire can be put out with a hand fire extinguisher. A burning (smoking) tire or fire in the brake area is hazardous. These are sure indications of a hot tire. There is no completely safe way to get near a machine to put out this type of hazardous fire. Go near only at the front or rear of a machine and use a large bulldozer as a shield.Current Recommendation
Use dry nitrogen (N2) gas for all pneumatic tires. Nitrogen will not burn inside the tire.
Correct nitrogen inflation (charging) equipment and training in its use are needed to prevent too much pressure in a tire. A tire blowout or rim failure can result from equipment that is not correct or is not correctly used.
Also, the use of nitrogen instead of air in the tires, decreases the amount of tire deterioration. This is especially important for tires that have an expected long service life (4 or more years). It also decreases the corrosion of rim components, which decreases disassembly problems.The pressure of a fully charged nitrogen cylinder is approximately 15 000 kPa (2200 psi). This high pressure can cause a tire blowout and or rim failure if the charging equipment is not used correctly. See Tire Inflation (Charging) With Nitrogen.Tire Inflation (Charging) With Nitrogen
Servicing and changing tires and rims can be dangerous. This work must be done only by trained personnel with correct tools and procedures. If correct procedures are not followed while servicing tires and rims, the assemblies can burst with explosive force and cause serious physical injury or death. Follow carefully the specific information provided by your tire servicing man or dealer.
When tires are changed, be sure to clean all rim parts.
