“Big Builders hired a crane together with its driver Alfred from Cranes Ltd for six months for a special building project. On two occasions last week Alfred had felt light-headed when he got up. He attributed this to exhaustion as he had been kept awake most of the night by his crying baby. He did however make an appointment to see his doctor in two weeks time. Yesterday, while operating the crane, he fainted. The jib of the crane swung loose and looked as though it would strike against scaffolding. Ben, an employee of Big Builders, who contrary to safety guidelines was climbing up the outside of the scaffolding, jumped clear and was seriously injured when he fell. David, another employee of Big Builders, tried to climb up into the cab of the crane in order to help Alfred, also fell and was injured. Advise Ben and David.”
