1/18/2022 - Change to the 2022 edition of NFPA 80 – Standard for Fire Doors and Other Opening Protectives.
Prior to the 2022 edition, the total area of all attached signs could not exceed 5% of the area of the face of the door – regardless of what material the sign was made of. The 2022 edition includes the same limitation of 5% but specifies that the limit applies to signage made from combustible materials or from vinyl up to 0.008 inches (2 mm) thick.
Past editions of the standard required signage to be attached to fire doors with adhesive, and specifically prohibited the use of screws or nails. The 2022 edition allows adhesive OR up to 4 steel or stainless steel fasteners IF the screws are used to attach metal signs and if they penetrate one side of the fire door.
