NAICS industry code: 562119

Two ERA Removal employees were working on a lift, removing iron brackets on the outside of a five-story building under a 3-foot-wide, cantilevered slab from the roof deck/area above the fifth floor. The block parapet for the roof was built on this slab. A third employee was working from a ladder on the fifth floor. The cantilevered slab from the roof with the block parapet sheared off the building and fell down three floors, damaging and collapsing the third- and fourth-floor cantilevered slabs. The two employees on the lift were hit with a large chunk of the parapet. The third employee jumped off the ladder onto the fifth floor. Two employees were hospitalized for contusions and lacerations to the head.
