The most common accident occurs from falls from heights on a construction site. Falls can be from scaffolding, excavation equipment, ladders, stairways, trenches (both falling in and or collapse), elevators, cranes, forklifts and other types of elevated construction equipment equipment,

Falling items are also a significant danger on a construction site. These objects can be beams, chains, metal plates, pieces of equipment, bricks, wood, or any other type of building material.

Falling objects usually cause serious injury due to the speed and weight of the objects involved. Further, it is difficult to prevent serious injury from a falling object, as generally the falling object will strike someone on or near the head. This can cause concussions, brain injury, or death.
