More Information
Excavation refers to the process of digging trenches and does not specifically protect against cave-ins. In contrast, sloping, shoring, and trench boxes are methods specifically designed to protect workers from trench cave-ins.
Tips
A common mistake is to assume excavation is a protective method, while it's actually the process requiring protective measures.
