Why this matters
Spoil, materials, and machines close to an excavation add load to the wall and can fall in.
What to cover
- Keep spoil and materials back from the edge.
- Use barriers and signs to mark the edge.
- Use stop blocks for trucks that tip or reverse to the edge.
- Cross trenches only at crossings with handrails.
- Check the edge after rain and vibration.
- Don't stand or work at the edge without protection.
Ask the crew
- How far back is our spoil?
- Where do people cross?
- What changes the edge here?
One thing to do today
Measure the stand-off at each excavation and fix any that are too close.
