Rain, freezing, or even vibration from equipment can weaken trench walls.
Why It Matters:
What was safe an hour ago might not be now. Soil conditions change fast and silently — especially after storms or nearby activity.
Key Points:
- Inspect trenches after rain, frost, or vibrations from heavy equipment.
- The Competent Person must re-check trench stability and verify protection systems.
- Never resume work until the trench is cleared as safe for entry.
- Document changes and communicate with the crew during huddles or shift hand-offs.
✅ Yesterday’s safe trench can be today’s trap. Stay alert.
Ask the Crew:
- Has weather affected trench stability recently?
- Are we inspecting and communicating after each storm or shift?
