1025.2.6.3 Door frame markings.

The top and sides of the door frame shall be marked with a solid and continuous 1- to 2-inch (25.4 mm to 50.8 mm) wide stripe. Where the door molding does not provide sufficient flat surface on which to locate the stripe, the stripe shall be permitted to be located on the wall surrounding the frame.

1025.2.7 Directional signage upon entering an interior exit stairway or ramp.

Luminous directional signs designed in compliance with Section 1025.6.1 shall be placed in the interior exit stairway or ramp at every entrance thereto such that they are readily visible when the doors are in the open and closed positions. Such directional sign shall include an arrow indicating the direction of travel. The word "EXIT" shall not be required. The signs shall be located such that their top edge is within 18 inches (457.2 mm) above the finished floor. Directional signs shall comply with Figure S101.1(9) in Appendix S.

1025.2.8 Directional signage at transfer levels and where egress direction is not clear.

Luminous directional signs designed in compliance with Section 1025.6.1 and installed at heights indicated in Section 1025.2.7 shall be placed on the wall at transfer levels and wherever egress direction is not clear; including at turns along horizontal extensions, at transitions from vertical to horizontal direction and at a "T" intersection. These directional signs shall include arrows indicating the direction of travel. The word "EXIT" shall not be required. Directional signs at transfer levels shall comply with Figure S101.1(9) in Appendix S.

1025.2.9 "No Exit" sign.

Luminous signs shall be placed on doors along the egress path that lead to dead ends (mechanical rooms, storage closets, etc.). Such signs shall contain sans serif lettering at least 1 inch (25.4 mm) high reading "NO EXIT", with the "NO" centered above the "EXIT". The "NO" may be a larger size than the "EXIT" for clarity. The nonluminous portion of such signs shall not be green. No-exit signs shall comply with Figure S101.1(10) in Appendix S.

1025.3 Uniformity.

Placement and dimensions of markings shall be consistent and uniform throughout the same enclosure.

1025.3.1 Solid and continuous.

For the purposes of this section, solid and continuous means without gaps or interruption, except as required for the control of expansion and contraction. A series of dashes, chevrons, dots, or other similar patterns is not solid and continuous. Luminous materials shall be considered solid and continuous if they occasionally contain the following safety green (ANSI Z 535.1) symbols or text:

   1.   The word "EXIT";

   2.   Egress symbol as per NFPA 170;

   3.   Direction arrows as per NFPA 170; or

   4.   Other text or symbols as approved by the commissioner.

1025.4 Self-luminous and photoluminescent.

Luminous egress path markings shall be permitted to be made of any material, including paint, provided that an electrical charge is not required to maintain the required luminance. Such materials shall include, but not be limited to, self-luminous materials and photoluminescent materials. Materials shall comply with either of the following standards:

   1.   UL 1994.

   2.   ASTM E 2072, except that the charging source shall be 1 footcandle (11 lux) of fluorescent illumination for 60 minutes, and the minimum luminance shall be 30 millicandelas per square meter at 10 minutes and 5 millicandelas per square meter after 90 minutes.
