What is the primary function of a spreader in construction?

The primary function of a spreader in construction is to support walls that are collapsing outward. When walls begin to fail, particularly in situations where lateral forces are applied, a spreader is employed to prevent further movement and provide stability. It works by transferring the load of the wall across a broader area, which effectively helps to hold the structure in place and prevents total collapse.

This support is critical in maintaining the integrity of the remaining structure and ensuring the safety of workers and responders on site. By counteracting the outward forces acting on the wall, the spreader can help to stabilize the situation until more permanent measures can be taken.

While other options mention supporting walls, distributing forces, or gaining entry, they do not specifically address the role of a spreader in preventing outward wall movement, which is its primary purpose in construction and incident management scenarios. Understanding this function is vital for ensuring effective stabilization in construction and emergency situations.
