    Abstract: Devices and methods are provided for protecting pipe ends that project upwardly during building construction and for reducing the safety hazard posed by such pipe ends. The devices include a rigid body suitable for positioning on a base on which concrete will be poured, having two opposed end walls, two opposed side walls, a recess therebetween, a top end, a bottom end, and a lateral tab extending from at least one end wall. A shield is securable to at least one side wall for protecting the pipe ends during later construction. In two embodiments, a plate positioned at the bottom end has an opening dimensionally and spatially configured to correspond to each pipe end requiring protection.
