Road Grader Operation Safety

Key Hazards

• Workers or vehicles struck in the grader's long blind spots and turning path
• Rollover or loss of control on slopes, road edges, and soft shoulders
• Crush and pinch hazards at the articulation joint, moldboard, and linkages
• Collision with utility covers, signs, culverts, overhead lines, and structures
• Material, rocks, or debris thrown toward workers, traffic, or property
• Unexpected blade, ripper, or hydraulic movement during inspection and service

2–3 Minute Talk Script

Road graders are long, articulated machines whose wheels, frame, and moldboard may move in different directions. The operator should inspect the machine and walk the work area before grading begins.

Brakes, steering, articulation, tires, mirrors, cameras, alarms, lights, seat belt, rollover protection, hydraulic systems, moldboard, circle, scarifier, and attachments should be checked for safe operation.

Workers on foot should remain outside the grader's travel path, articulation area, moldboard sweep, and blind spots. An agreed communication method should be used before anyone approaches the machine.

The operator should identify road edges, drop-offs, soft shoulders, culverts, drainage structures, utility covers, valves, signs, mailboxes, bridges, parked vehicles, and overhead hazards before placing the blade.

Speed, blade angle, articulation, wheel lean, and material windrow should be controlled so the machine remains stable and debris is not directed into workers, traffic, buildings, or parked vehicles.

Extra care is required on slopes, crowns, curves, and narrow roads. Sudden steering or articulation, excessive speed, and working too close to an unsupported edge can cause loss of control or rollover.

Backing and multi-point turns should be minimized and planned. The operator should stop when workers, vehicles, or the public enter the blind area or when dust and weather prevent a clear view.

Before parking or service, the moldboard and attachments should be lowered, controls neutralized, brakes applied, and hydraulic pressure relieved as required. Raised components should be positively blocked before anyone works beneath them.

Safety Reminders

• Inspect articulation, steering, brakes, visibility aids, and attachments.
• Keep workers clear of blind spots, articulation, and moldboard movement.
• Identify road edges, utilities, drainage structures, and overhead hazards.
• Control speed, blade angle, and debris direction.
• Use extra caution on slopes, crowns, curves, and soft shoulders.
• Plan backing and stop when visibility is inadequate.
• Lower and block attachments before service.

Ask the Crew

• Where are the grader's blind spots and articulation hazards?
• What road-edge, drainage, utility, or overhead hazards are present?
• Where will the windrow and thrown material travel?
• How do slope, crown, and shoulder conditions affect stability?
• What must be lowered or blocked before maintenance?
