Excavation and working over water

CSP written lesson, 10 min read. CSP Domain 1: Advanced Application of Safety Principles

AI-drafted from the cited rules and fact-checked against them. Study aid, not site-specific safety advice. The official rule controls.

What you'll learn

  • State the utility location steps required before and during excavation
  • Apply the egress, spoil-setback and falling-load rules to a trench
  • Apply atmosphere testing and water accumulation rules to an open excavation
  • Identify who inspects an excavation and when, and who approves ramps and footings
  • List the life jacket, ring buoy and skiff requirements for work over water

What this lesson covers

This lesson covers the construction rules for opening, entering and inspecting excavations, and for working over or near water. It matters because the exam tests the exact numbers and who must act, and because trench and water hazards kill quickly on real jobs.
