Construction safety, building construction: Two workers install plywood sheathing on roof trusses on 2-story residential building. Workers are standing on previously erected sheathing, at a significant slope, without fall protection. They carry the 4'x8' sheets of plywood sheathing as they need them from the Caterpillar hydraulic telescoping boom 4-wheel drive rough terrain forklift. One slip and a worker rolls down roof and falls ~20' off edge or hits open trusses and may fall through them. Fort Myer Beach, Florida 2005
