What is the difference between Class 1, 2, 3 and E apparel?
Class 1 apparel is required to provide the minimum amount of necessary material to differentiate the wearer from the work environment. Class 2 apparel provides superior visibility for wearers by the additional coverage of the torso, and is more conspicuous than Class 1. Class 3 apparel is intended to offer greater visibility to the wearer in both complex backgrounds and through a full range of body movements. Class 3 visibility is enhanced beyond Class 2 by the addition of background and retroreflective material to the arms and/or legs. Class E apparel applies to trousers and shorts and creates a high visibility ensemble. When Class E bottoms are worn with a Class 2 or 3 garment, the overall classification for the ensemble is Class 3.
