Leader note: Do not read this sheet word-for-word. Pick the sections that match today’s task, point to the actual equipment/work area, and get the crew to answer the questions out loud.

Why this matters

Use today's Mobile Equipment Near Excavation Edges talk as a quick crew check on equipment roll-in and workers struck in blind spots. Talk through the real conditions, the controls in place and what would make the crew stop and reset the job. Heavy equipment injuries are rarely about speed alone. Blind spots, changing ground conditions, unexpected pedestrian movement and poor communication put people where operators cannot see them or cannot stop in time.

A scenario to discuss

During Mobile Equipment Near Excavation Edges, a delivery, parked vehicle, stockpile, or another machine blocks part of the operator’s normal view. The route is still passable. What must change before the machine moves through the altered area?

Before work starts

Walk the equipment route and mark pedestrian separation, blind corners, edges and overhead hazards.
Complete the operator/pre-use inspection and confirm seat belt, alarms, mirrors/cameras and controls are functional.
Agree on spotter positions and the stop signal before the machine moves.
Use barricades, stop logs, spotters or other controls where operators approach excavation edges.
Keep workers out of equipment swing/travel zones.

Common failure points

Backing or swinging with a blind area that has not been cleared or controlled.
Operating near edges/slopes/overhead hazards without a deliberate route and spotter plan.
Assuming pedestrians will see or hear the machine and stay out of the way.

Safe work sequence / controls

Use barricades, stop logs, spotters or other controls where operators approach excavation edges.
Keep workers out of equipment swing/travel zones.
Plan haul routes to reduce reversing close to trenches.
Coordinate eye/contact signals before a worker approaches operating equipment.

Stop and reset the plan if...

The operator loses a clear travel path, spotter communication or required visibility.
Ground conditions, slope, overhead hazards or edge conditions are outside the planned operating limits.
Pedestrians, vehicles or other trades enter the equipment operating zone unexpectedly.

Questions worth asking the crew

What are the operator's blind spots in today's setup, and exactly where must pedestrians stay out?
What ground, slope, edge, overhead, or clearance condition could put this machine outside its safe operating limits?
When visibility is restricted, who is spotting and what exact signal means STOP?
How does the risk change when the machine is loaded, backing, turning, or using the planned attachment?
Has anyone had a pedestrian, blind spot or ground condition surprise an operator? What control would have caught it sooner?

Make it real on the job

Stand where a pedestrian could be missed and make sure the operator/crew understand that blind spot.

Close the talk

Before the crew starts, everyone should be able to explain the hazard, point to the control being used today, and name the condition that would make the work stop.
