Field scenario: The work face points toward a trail, and the downhill runout points toward the customer’s driveway.
Why this matters
Slope work combines thrown-object risk with downhill machine/runout risk, so normal perimeter thinking is not enough.
Pass standard
People are kept out of both the thrown-object zone and the machine’s possible slide/roll path.
- Slope work has two hazard patterns: thrown objects from the head and machine movement if traction/control is lost.
- Keep people, vehicles, and helpers outside both the thrown-object zone and downhill/roll path.
- Use a spotter only when they can stand in a safe position with clear communication — never as a human barrier.
- Stop immediately for people, pets, vehicles, loss of visibility, loss of signal, unstable movement, fire, or rollover risk.

Common mistakes
- Putting a spotter in the downhill path.
- Only controlling the cutter-head side.
- Letting trails/driveways remain open below the work.
Document in Jobber
- Photos of blocked trail/driveway/access points.
- Spotter location/communication notes.
- Downhill runout hazards.
Field standard: A spotter helps control risk; a spotter never absorbs risk.
