Trenching and excavation basics

Trench collapses happen fast and are often deadly.

Key points

• Trenches 5 feet or deeper need protection.
• A competent person inspects daily.
• Keep spoil piles at least 2 feet from the edge.
• Use a ladder within 25 feet of workers.
• Watch for water, cracks and bulges.

Ask the crew

• Who inspects the trench today?
• Where is the ladder?
