Trench boxes are a typical type of trench protection, offering sturdy walls and a frame that guard against cave-ins for workers inside. However, a poorly built trench box won’t offer any protection to the workers down there. The walls may compress if the earth caves in improperly pinned spreader bars.
What are 3 protective measures that can be used in trenches?
Staying protected
- Sloping (or benching) (or benching). Removing a portion of the trench wall at an angle that is incline toward the excavation.
- Shoring. installing supports made of aluminum or other materials to stop cave-ins.
- Shielding. To avoid cave-ins, use trench boxes or other supports.

trench warfare is a type of conflict in which the two sides engage in turns of attack and defense from rows of dug-in trenches. It was created in the 17th century by Sébastien Le Prestre de Vauban for besieging fortifications. During the American Civil War, its defensive use was first institutionalized as a strategy.
