There is no shortage of hazards that can kill you on a construction site, but you never think it is going to be a flying chunk of concrete. That is how laborers’ foreman Michael Hanson, 42, was fatally injured on Nov. 26, 2007, while working at the Palazzo Resort Hotel Casino on the Las Vegas Strip.

A project foreman whose crew was using a rough-terrain forklift to pry loose a temporary concrete slab, Hanson stood in front of the fork tine extensions that had been slid under the slab. He was leaning over, assisting in prying material loose, when the slab snapped and sent a concrete projectile flying into his head. Hanson died the next evening; he never regained consciousness.
