Excavation — Water and Utility Crossings
Construction · Ver en español
Talking points
- When an existing utility crosses the trench, it must be supported, protected, or relocated before the trench extends past it. An unsupported crossing can collapse into the trench.
- Water lines crossing a trench are heavy when full and can break if undermined. A broken water line can flood a trench rapidly, creating drowning and cave-in hazards simultaneously.
- Gas lines require special precautions. Monitor for gas with a combustible gas detector, provide ventilation, and eliminate ignition sources when working near exposed gas utilities.
- Support crossing utilities with appropriate hangers, brackets, or cribbing. Do not use the utility itself as a step, handhold, or anchor — the load can break the connection.
- If a utility is damaged during excavation, shut down operations immediately, evacuate the trench, and contact the utility company. Do not attempt repairs on damaged gas or electrical lines.
Ask the crew
Are there any utilities crossing our excavation — and are they properly supported and protected?

A toolbox talk is a short safety briefing. It supports the training a standard requires; it does not replace it.
