Bulldozer Smart Bulldozer Incident Free Bulldozers are designed to cut and push large quantities of material in a matter of seconds. With their enormous size, they can cause serious injury and even death, if not operated properly. • Only qualified, competent and trained workers should be allowed to operate and ride on bulldozers. • Operators must always use seatbelts when riding or operating the bulldozer. • Start the engine only when seated on the operator’s seat and when the path is clear of workers, objects and other obstructions. • Workers must follow proper lockout, block-out and tagout procedures, especially when a bulldozer is in need of repairs. • Use a system of traffic controls when operating the bulldozer on a public thoroughfare or in an area close to vehicle traffic or obstructing it. • Flaggers must be assigned in areas where warning signs and barricades cannot control traffic flow. • Keep bulldozers away from overhead power lines. • Before operations, qualified personnel must test if the manual warning device (horn) of the bulldozer works. • The bulldozer must also be equipped with an automatic back-up alarm that can be heard through the whole worksite. • Shut off the engine whenever refueling. The bulldozer must be equipped with rollover protection structures (ROPS). Never climb on parts of the machine where hand and foot holds are not provided. Be doubly cautious when approaching or operating near trenches or excavations. Never use the bulldozer on structures that are taller than the bulldozer itself, unless there is sufficient overhead protection. Pre-Use Activities Thoroughly review and understand information provided in the bulldozer operator’s manual with particular attention given to descriptions of safety procedures. Always perform a pre-shift inspection, including fluid levels, brakes, steering, lights and signals, tires, hydraulic cylinders/lines, horns, operating controls, seat belts and safety devices. If a dozer fails the pre-shift inspection, notify your supervisor and remove the dozer from service by attaching a red tag stating, “DO NOT USE.” Note reason, date and name on the tag. Refresher training is required annually and an evaluation of each operator’s performance must be conducted at least once every three years. Operating Precautions Before operating a dozer, check the work area for obstructions and hazards including, ditches, slopes, hills, excavations, streams, and underground and aboveground utility lines. Employees working within the dozer work area must wear flagging garments (i.e., orange vests) and at least, a hard hat, steel-toed boots, and long pants. Never carry passengers on a bulldozer and stunt driving is prohibited. Do not operate a dozer with a leaking fuel system or leaking brake system. Bulldozers must be equipped with rollover protection structures (ROPS). Operators must always use seatbelts when operating a bulldozer. Operators must mount and dismount using only the steps and handholds provided on the dozer. Dozer blades and attachments must be kept close to the ground while moving. Dozers should be parked on level ground whenever possible. The bulldozer must be equipped with an automatic back-up alarm. Shut off engine whenever refueling. Never use a bulldozer to demolish structures that are taller than the dozer itself, unless there is sufficient overhead protection. Mechanics must follow proper lockout, block out, and tagout procedures when a bulldozer is in repair. When parking, shift into neutral and set the parking brake to immobilize the dozer. Lower the blade and any other attachment to the ground then shut off engine. Operators must use proper towing procedures and equipment for bulldozer attachments. One of the top safety requirements is “do not drive a vehicle or equipment in reverse gear with an obstructed rear view, unless it has an audible reverse alarm distinguishable from the surrounding noise level or another worker signals that it is safe.” In this case, the truck driver did not make sure that personnel were in the clear and did not use someone to help with signaling. It resulted in an end of life.
