✅ Explanation
Deep excavation is a high-risk activity because workers may face serious dangers such as: 👉 Cave-in
👉 Underground utility damage
👉 Falling into excavation

👉 Method statement
👉 Underground utility drawing
👉 Soil test report
👉 Excavation layout drawing
👉 Equipment inspection certificates
👉 Operator competency certificates

👉 Daily excavation inspection checklist
These documents help the company:
✔ Identify hazards before work starts
✔ Apply proper control measures
