Key Hazards
- Vehicles or equipment rolling unexpectedly
- Chocks sliding, shifting, or failing on poor surfaces
- Pinched fingers while placing or removing chocks
- Using chocks that are too small or damaged
- Forgetting to set brakes or follow site securement procedures
- Workers standing in the path of a vehicle that could move
2–3 Minute Talk Script
Wheel chocks help prevent vehicles, trailers, and equipment from moving unexpectedly. They are a simple control, but they only work when selected and placed correctly.
Workers should use chocks that are appropriate for the tire size, vehicle weight, surface, and slope. A small or lightweight chock may not hold a heavy vehicle or trailer.
The parking brake or other required securement controls should be used along with chocks. Chocks should not be treated as the only protection when other procedures require additional controls.
Chocks should be placed snugly against the tires in the direction movement could occur. On slopes or when loading and unloading, both sides may need to be controlled depending on the setup.
Surface conditions matter. Gravel, mud, ice, snow, loose dirt, wet pavement, or uneven ground can reduce chock effectiveness.
Workers should keep hands and feet clear when placing and removing chocks. Tires can shift, and chocks can pinch fingers if the vehicle moves slightly.
Chocks should be inspected before use. Cracked, crushed, slick, worn, or undersized chocks should be removed from service.
Safe wheel chock use depends on matching the chock to the vehicle and surface, placing it correctly, setting brakes, and staying out of the vehicle’s potential path of travel.
Safety Reminders
- Use chocks sized for the vehicle and tire.
- Inspect chocks before use.
- Set brakes and follow securement procedures.
- Place chocks snugly against the tire.
- Use extra caution on slopes or loading docks.
- Keep hands and feet clear when placing or removing chocks.
- Do not stand in the path of possible vehicle movement.
Ask the Crew
- Is the chock the right size and type for this vehicle?
- Is the surface firm enough for the chock to hold?
- Have brakes or other securement controls been applied?
- Where could the vehicle move if the chock failed?
- Are workers clear of pinch points and rollaway paths?
