Workers were installing formwork and concrete at a building project when a worker fell about 10 meters through an opening in a concrete slab and died. An MOL investigation found that the opening’s protective floor covering, which was unmarked and unsecured, had been removed before the worker fell through. The constructor pleaded guilty to a safety offence as to the floor covering. The court fined it $160,000 [Res 2000 Structures Inc., Govt. News Release, April 4, 2012].
