that contain asbestos or when you handle asbestosdebris.

Use caution. Avoid inhaling dust that might begenerated when you handle components thatcontain asbestos fibers. Inhaling this dust canbe hazardous to your health. The componentsthat may contain asbestos fibers are brake pads,brake bands, lining material, clutch plates, andsome gaskets. The asbestos that is used in thesecomponents is usually bound in a resin or sealed insome way. Normal handling is not hazardous unlessairborne dust that contains asbestos is generated.

If dust that may contain asbestos is present, thereare several guidelines that should be followed:

• Never use compressed air for cleaning.

• Avoid brushing materials that contain asbestos.

• Avoid grinding materials that contain asbestos.

• Use a wet method in order to clean up asbestosmaterials.

• A vacuum cleaner that is equipped with a highefficiency particulate air filter (HEPA) can also beused.

• Use exhaust ventilation on permanent machiningjobs.

• Wear an approved respirator if there is no otherway to control the dust.

• Comply with applicable rules and regulationsfor the work place. In the United States, useOccupational Safety and Health Administration(OSHA) requirements. These OSHA requirementscan be found in “29 CFR 1910.1001”.

• Obey environmental regulations for the disposalof asbestos.

• Stay away from areas that might have asbestos

particles in the air.

Dispose of Waste Properly


Improperly disposing of waste can threaten theenvironment. Potentially harmful fluids should bedisposed of according to local regulations.

i01557411

Tire Information

SMCS Code: 7000

Explosions of air inflated tires have resulted fromheat-induced gas combustion inside the tires.Explosions can be caused by heat that is generatedby welding, by heating rim components, by externalfire, or by excessive use of brakes.

A tire explosion is much more violent than ablowout. The explosion can propel the tire, the rimcomponents, and the axle components as far as500 m (1500 ft) or more from the machine. Both theforce of the explosion and the flying debris cancause property damage, personal injury, or death.


(A) At least 15 m (50 ft)(B) At least 500 m (1500 ft)

Do not approach a warm tire. Maintain a minimumdistance, as shown. Stay outside the shaded areain Illustration 36.

Do not use water or calcium as a ballast for thetires. Dry nitrogen gas is recommended for inflationof tires. If the tires were originally inflated with air,nitrogen is still preferred for adjusting the pressure.Nitrogen mixes properly with air.

Nitrogen inflated tires reduce the potential of atire explosion because nitrogen does not aidcombustion. Nitrogen helps to prevent oxidation ofthe rubber, deterioration of rubber, and corrosionof rim components.

To avoid overinflation, proper nitrogen inflationequipment and training in the usage of theequipment are necessary. A tire blowout or a rimfailure can result from improper equipment or frommisused equipment.

When you inflate a tire, stand behind the tread anduse a self-attaching chuck.

Servicing tires and rims can be dangerous. Onlytrained personnel that use proper tools and properprocedures should perform this maintenance. Ifcorrect procedures are not used for servicing tiresand rims, the assemblies could burst with explosiveforce. This explosive force can cause seriouspersonal injury or death. Carefully obey the specificinstructions from your tire dealer.

i01836198

Guards(Operator Protection)

SMCS Code: 7000; 7150; 7325

There are different types of guards that are used toprotect the operator. The machine and the machineapplication determines the type of guard that shouldbe used.

A daily inspection of the guards is required in orderto check for structures that are bent, cracked orloose. Never operate a machine with a damagedstructure.

The operator becomes exposed to a hazardous

situation if the machine is used improperly or if pooroperating techniques are used. This situation canoccur even though a machine is equipped with anappropriate protective guard. Follow the establishedoperating procedures that are recommended foryour machine.

Rollover Protective Structure(ROPS), Falling Object ProtectiveStructure (FOPS) or Tip OverProtection Structure (TOPS)

The ROPS/FOPS Structure (if equipped) on yourmachine is specifically designed, tested andcertified for that machine. Excavators are notequipped with ROPS structures. Any alteration orany modification to the ROPS/FOPS Structure couldweaken the structure. This places the operatorinto an unprotected environment. Modifications orattachments that cause the machine to exceedthe weight that is stamped on the certificationplate also place the operator into an unprotectedenvironment. Excessive weight may inhibit thebrake performance, the steering performanceand the ROPS. The protection that is offered bythe ROPS/FOPS Structure will be impaired if the

ROPS/FOPS Structure has structural damage.Damage to the structure can be caused by anoverturn, a falling object, a collision, etc.

Do not mount items (fire extinguishers, first aidkits, work lights, etc) by welding brackets to theROPS/FOPS Structure or by drilling holes in theROPS/FOPS Structure. Welding brackets or drillingholes in the ROPS/FOPS Structures can weakenthe structures. Consult your Caterpillar dealer formounting guidelines.

The Tip Over Protection Structure (TOPS) is anothertype of guard that is used on mini-hydraulic

excavators. This structure protects the operator inthe event of a tipover. The same guidelines for theinspection, the maintenance and the modification ofthe ROPS/FOPS Structure are required for the TipOver Protection Structure.

Other Guards (If Equipped)

Protection from flying objects and/or falling objectsis required for special applications. Loggingapplications and demolition applications are twoexamples that require special protection.



23Safety Section

Steering Frame Lock

A front guard needs to be installed when a worktool that creates flying objects is used. Meshfront guards that are approved by Caterpillar orpolycarbonate front guards that are approved byCaterpillar are available for machines with a cab oran open canopy. On machines that are equipped

with cabs, the windshield should also be closed.Safety glasses are recommended when flyinghazards exist for machines with cabs and machineswith open canopies.

If the work material extends above the cab, topguards and front guards should be used. Typicalexamples of this type of application are listed below:

• Demolition applications

• Rock quarries

• Forestry products

Additional guards may be required for specificapplications or work tools. The Operation andMaintenance Manual for your machine or yourwork tool will provide specific requirements for theguards. Consult your Caterpillar dealer for additionalinformation.

i01741550
