Scout's Toolbox Talks

Loose soil can slide back into the trench — especially on slopes, in wet conditions, or if the pile is too steep.

Why It Matters:

Rollback doesn’t just threaten trench stability — it can bury tools, damage protective systems, or trap workers inside the trench. Many trench incidents happen after the digging is done.

Key Points:

• Compact spoil piles regularly to prevent sloughing or settling.
• Never store tools or materials on top of spoil piles — they can roll in too.
• Slope or bench spoil piles if needed to reduce steep sides.
• Avoid placing spoil piles on unstable ground (e.g., frozen, saturated, or sloped toward the trench).
• Use trench shields or end protection if rollback risk is high.

✅ What goes up shouldn’t roll back down — manage your spoil zone with intent.

Ask the Crew:

• Are our spoil piles compacted and stable?
• Has rain, vibration, or digging made rollback more likely?
• Are we keeping tools and materials off the piles?
