Trench Box
A Trench Box, also known as a trench shield or shoring box, is a vital safety equipment used in construction and excavation work. It consists of large metal plates that protect workers who need to work in deep trenches or excavations. Think of it like a strong metal box that prevents soil from collapsing onto workers while they're installing pipes, maintaining utilities, or performing other underground work. When you see this term on a resume, it indicates that the candidate has experience with safe excavation practices and understands OSHA safety requirements for working in trenches.
