Which of the following is not one of the basic methods to protect workers from trench cave-ins? A) Excavation B) Shoring C) Trench boxes D) Sloping

Understand the Problem

The question is asking to identify which option is not considered a basic method for protecting workers from trench cave-ins. It provides four options: Excavation, Shoring, Trench boxes, and Sloping, and requires the respondent to select the one that doesn't belong to the group of protective methods.

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.
