Final answer:
To prevent materials and equipment from falling on people working on lower levels, Domenico should use guardrails, store materials away from the roof edge, keep excess materials in a designated area, and ensure stability of piled materials.
Step-by-step explanation:
To prevent materials and equipment from falling on people working on lower levels, Domenico should take several safety measures:
- Use guardrails with small openings to prevent passage of potential falling objects.
- Store materials and equipment at least 2 feet away from the roof edge to create a safe distance.
- Keep excess materials and debris in a designated area on the roof away from the work area to minimize the risk of them falling on workers below.
- Ensure that the materials piled, grouped or stacked are stable and self-supporting to prevent them from toppling over and causing accidents.
By following these safety practices, Domenico can greatly reduce the risk of materials and equipment falling on people working on lower levels.
