Trenching and Excavation:
Failure to Inspect Trench and Protective Systems

Am I In Danger?

If trenches and excavations at your site are not inspected daily for evidence of possible cave-ins, hazardous atmospheres, failure of protective systems, or other unsafe conditions, you are in danger.

How Do I Avoid Hazards?

Inspect excavations:

  • Before construction begins.

  • Daily before each shift.

  • As needed throughout the shift.

  • Following rainstorms or other hazard-increasing events (such as a vehicle or other equipment approaching the edge of an excavation).

Inspections must be conducted by a competent person who:

  • Has training in soil analysis.

  • Has training in the use of protective systems.

  • Is knowledgeable about the OSHA requirements.

  • Has authority to immediately eliminate hazards.

To help evaluate different protection systems and identify the warning signs of excavation failure, see the Guide for Daily Inspection of Trenches and Excavations.
