Bulldozers are powerful earthmoving machines with large blades that create significant blind spots for the operator. Workers on foot near a bulldozer are at high risk of being struck because the operator may not be able to see them. This talk covers the key hazards associated with bulldozer operations, the blind spot areas, and the controls needed to keep pedestrians and operators safe on site.
Key Hazards
Pedestrians struck by bulldozers operating in their extensive blind spots
Machine overturning on steep slopes or soft unstable ground conditions
Workers crushed between the blade and fixed objects during positioning
Hearing damage from prolonged exposure to high noise levels near the machine
Control Measures
Establish exclusion zones around the bulldozer's operating area to keep pedestrians clear.
Use a banksman to guide the operator when working near other personnel or fixed structures.
Ensure the operator holds a current CPCS or NPORS card for the specific machine category.
Carry out a pre-use inspection of the machine including tracks, blade, hydraulics, and safety systems.
Never approach a bulldozer from the rear or sides without making eye contact with the operator first.
Fit and maintain rear-view cameras or proximity warning devices where available on the machine.
Operate on slopes within the manufacturer's specified gradient limits to prevent overturning.
Wear hearing protection within the designated noise zone around the operating bulldozer.
Switch off the engine and lower the blade fully before leaving the cab or carrying out maintenance.
Remember
Never approach a bulldozer without first making direct eye contact with the operator
Exclusion zones must keep all pedestrians clear of the bulldozer's operating area
The operator must hold a current CPCS or NPORS card for the specific machine category
Pre-use inspections must cover tracks, blade, hydraulics, and all safety systems daily
Operate on slopes only within the manufacturer's stated gradient limits to prevent rollover
Lower the blade fully and switch off the engine before leaving the cab for any reason
