Equipment Rollovers: Stay in the Seat

When a dozer, loader, tractor or forklift tips over, instinct says jump. That instinct kills. The rollover protective structure (ROPS) and seat belt are designed to keep you inside a protected space. Operators who jump are crushed by the machine or the ROPS itself.

• Equipment operators
• Forklift operators
• Farm & landscaping

ROPS and seat belts work together

• ROPS (rollover protective structure) is the cab frame or roll bar built to protect the operator if the machine rolls. OSHA requires ROPS on many earthmoving machines, loaders, dozers, scrapers and tractors.
• The seat belt keeps you inside the ROPS zone. Without it, you can be thrown out and crushed.
• On forklifts, the overhead guard and seat belt (or operator restraint) do the same job in a tip-over.
• Never remove or modify a ROPS, and don’t drill or weld on it. A damaged ROPS must be repaired or replaced as the maker says.
• Folding ROPS on tractors must be up and locked whenever you can safely do so.

If the machine starts to tip

1. Stay in the seat with your belt on.
2. Hold on firmly to the steering wheel or a handhold.
3. Brace your feet.
4. Lean away from the direction the machine is falling.

Common causes

• Crossing a slope sideways, or turning on a slope
• Getting too close to excavation edges, ditches and embankments
• Traveling with the load or bucket raised
• Driving too fast or turning sharply, especially on forklifts
• Hitting holes, curbs, stumps or debris
• Overloading, or loads off-center
• Loading onto trailers on slippery ramps

See Operating on Slopes & Unstable Ground and Loading Equipment onto Trailers.

After a rollover

• Turn off the engine if you can.
• Check yourself for injuries before moving.
• Watch for fuel leaks, fire and hot fluids.
• Get out carefully once the machine has stopped moving, or wait for help if you’re hurt or trapped.
• Report it. The machine must be inspected before use, and a damaged ROPS replaced.

Daily habits

• Seat belt on every time the machine moves
• ROPS undamaged and in place; tractor ROPS up and locked
• Loads and buckets carried low
• Ground and slopes checked before working
• Speed matched to conditions
