The London 2012 Olympic and Paralympic Games: practical solutions to significantly reduce the hand arm vibration and noise hazards.

The Olympic Stadium contains 80,000 seats secured by four bolts to the concrete terrace. This work involved a lengthy and repeatable process of drilling into the concrete.A wheeled jig was developed for holding two drills originally designed to be hand held. This significantly reduced the hand arm vibration and noise hazards.The time required to complete the job was reduced as longer “trigger periods” (hours rather than minutes) were permitted and two holes were drilled simultaneously. The operator was further away from the noise source so the potential noise hazard was reduced. The wheeled jig also helped to reduce the need for lifting and carrying.
