Although we do not produce food, we were required by a customer to go through a scored AIB audit (which we passed). In our injection molding area, operators are required to wear gowns and hairnets to reduce the opportunity for hair or other contaminants from getting on a molded device. It is not a clean room environment. We have a crew leader that is currently required to wear a sling on his arm. He does not operate equipment as he is supervising the crew. He is still wearing the gown and the hairnet in addition to the sling. Has anyone else encountered this? I feel it is low risk.
