Massachusetts Hoisting License Practice Test

What requirement must be met for barricades around trenches?

1. They must be made of metal

2. No openings greater than four inches between vertical supports

3. They can have no height restrictions

4. They must be painted bright colors

The correct answer is: No openings greater than four inches between vertical supports

Barricades around trenches are crucial for ensuring the safety of workers and the public. The requirement that there are no openings greater than four inches between vertical supports is significant for several reasons. It prevents small individuals, such as children, from gaining access to the trench area, which could result in serious accidents or injuries. Moreover, limiting the openings helps ensure that tools or materials cannot inadvertently fall into the trench, potentially causing hazards or injuries to those working below. While the construction materials, height restrictions, or color of barricades may also influence safety, the focus on minimizing openings is a clear, specific safety measure that directly addresses the risks associated with trenches. This design element is critical to maintaining a secure perimeter and promoting overall workplace safety.
