What You'll Learn

  • Identify common hazards in trenching and excavation work, including wall collapse, struck utilities, and protective system failure
  • Explain OSHA requirements for trench safety and protection
  • Select and apply appropriate trench protection systems such as sloping, benching, shielding, and shoring
  • Describe the role and duties of the competent person
  • Follow inspection and response procedures for trench stability, including daily inspections and atmospheric testing
  • Assess how soil type, weather, and trench depth affect collapse risk and address access, egress, and setback before work begins

Key Takeaways

  • Trenches can become deadly when walls collapse, utilities are struck, or protective systems fail.
  • Soil type, weather, and trench depth affect collapse risk, which is why daily inspections are required.
  • Key protective systems include sloping, benching, shielding, and shoring, selected based on site conditions.
  • Trench access, egress, and atmospheric testing must be addressed before work begins.
  • The competent person is responsible for inspecting the worksite and responding when conditions change or signs of instability appear.
