Can I wear a non-FR jacket over my flame resistant PPE. NO
This is strictly forbidden. Your outermost layer should also be flame resistant. Under some conditions it is possible to wear 100% cotton (non-FR) garments under your flame resistant garments, however, it is exceedingly important that you do not wear any synthetic materials (such as polyester or nylon) under your arc and flame resistant garments. You should also avoid non-FR or synthetic accessories outside of your garments.
