Abstract: On March 11, 2003, Employee #1 was installing insulation in a roof decking from a work platform of a scaffold (Owens Corning Elaminator 300 series machine) without fall protection. The employer had provided safety belts and harnesses; however the foreman did not require their use. The scaffold was attached to the roof purlins via cantilever plates. After completing his work, Employee #1 pulled the connecting pins from the cantilever plate to begin dismantling the work platform. The manufacturer of the scaffold required that safety harnesses and lanyards be used when the dismantling operation is in progress. The rest of the insulation work was to be completed from aerial lifts. Employee #1 stepped back onto work platform for an unknown reason. The platform was disconnected from cantilever plate and tilted causing Employee #1 to fall. He fell approximately 50-ft, striking the ground and sustaining traumatic injuries. Emergency medical personnel were summoned and transported him to the hospital. At the hospital, he died from the traumatic injuries.
