Where a workplace process is likely to injure and other means cannot prevent the injury, each worker in that process who could be hurt is given suitable, appropriate protective equipment and clothing, which the employer supplies and maintains free of charge with instructions for its use. In the Schedule 8 processes, suitable goggles or effective screens protect the eyes of the workers engaged in them, and where electric welding exposes people other than the welders to the arc flash, effective screening or other provision prevents the exposure.
