Why this matters
Trench walls can collapse with no warning, and a small cave-in can bury a person.
What to cover
- Never enter an unprotected trench.
- A competent person inspects the trench before each shift and after anything that changes it.
- Use sloping, shoring, or a shield as the plan says.
- Keep spoil and equipment back from the edge.
- Make sure there's a ladder or ramp within reach.
- Don't work under suspended loads.
Ask the crew
- Who is the competent person today?
- What changes could weaken the walls?
- Where's the nearest way out?
One thing to do today
Check the protection and the exits on every trench before anyone enters.
