Scout's Toolbox Talks

You’ve got three ways to stay alive in a trench: sloping, shoring, or shielding. One must always be in place — no exceptions.

Why It Matters:

Even a 4-foot trench can collapse without warning. Soil shifts fast — and workers can’t outrun a wall of dirt. These protective systems are the only thing standing between you and a fatal crush injury.

Key Points:

• Sloping: Cutting trench walls back at an angle to prevent collapse. Angle depends on soil type (Type C needs the widest slope).
• Shoring: Using hydraulic, pneumatic, or timber supports to hold back trench walls. Great for deep or narrow trenches.
• Shielding: Placing trench boxes or shields in the trench to protect workers if a collapse happens. Remember — boxes don’t stop a collapse, they just protect what’s inside.
• System choice depends on:
  • Soil classification
  • Trench depth and width
  • Site layout and nearby loads (vehicles, materials, spoil)

✅ Use one — or don’t go in.

Ask the Crew:

• What system are we using today — and why?
• Has it been installed and inspected by the Competent Person?
• Are we inside the protection at all times — not just near it?
