1025.2.4.2 Wall-mounted demarcation lines.

Perimeter demarcation lines shall be placed on the wall with the bottom edge of the stripe not more than 4 inches (101.6 mm) above the finished floor. At the top or bottom of the stairs, demarcation lines shall drop vertically to the floor within 2 inches (50.8 mm) of the step or landing edge. Demarcation lines on walls shall transition vertically to the floor and then extend across the floor where a line on the floor is the only practical method of outlining the path. Where the wall line is broken by a door, demarcation lines on walls shall continue across the face of the door or transition to the floor and extend across the floor in front of such door. Wall-mounted demarcation lines shall comply with Figure S101.1(8) in Appendix S.

   Exceptions:

      1.   Demarcation lines shall not extend in front of exit discharge doors that lead out of an exit and through which occupants must travel to complete the exit path.

      2.   Perimeter demarcation lines are not required on the sides of steps.

      3.   Perimeter demarcation lines are not required where an area such as a dead end or an obstruction is selected not to be outlined because it is not part of the egress path, the demarcation lines shall not be required in such area provided that a demarcation line is continuous across the floor.

1025.2.4.3 Transition.

Where a wall-mounted demarcation line transitions to a floor-mounted demarcation line, or vice versa, the wall-mounted demarcation line shall drop vertically to the floor to meet a complementary extension of the floor-mounted demarcation line, thus forming a continuous marking. Transitioning demarcation lines shall comply with Figure S101.1(7) in Appendix S.

1025.2.5 Obstacles.

Obstacles at or below 6 feet 6 inches (1981.2 mm) in height and projecting more than 4 inches (101.6 mm) into the egress path shall be outlined with markings not less than 1 inch (25.4 mm) in width comprised of a pattern of alternating equal bands, of luminous material and black, with the alternating bands not more than 2 inches (50.8 mm) thick and angled at 45 degrees (0.79 rad). Obstacles shall include, but are not limited to, standpipes, hose cabinets, wall projections and restricted height areas. However, such markings shall not conceal any required information or indicators including but not limited to instructions to occupants for the use of standpipes. Markings on obstacles shall comply with Figure S101.1(6) in Appendix S.

1025.2.6 Doors within the exit path.

Doors through which occupants must pass in order to complete the exit path, and doors serving horizontal exits, shall be provided with markings complying with Sections 1025.2.6.1 through 1025.2.6.3 of this chapter and Figures S101.1(11) and S101.1(12) in Appendix S. Exit discharge doors shall further comply with Section 1025.2.6.1.2.

1025.2.6.1 Emergency exit symbol.

The doors shall be identified by a low-location luminous emergency exit symbol complying with Section 1025.6.1. The exit symbol shall be not less than 4 inches (101.6 mm) in height and shall be mounted on the door itself in accordance with Section 1025.2.6.1.1. Such signs shall be no higher than 18 inches (457.2 mm) above the finished floor.

1025.2.6.1.1 Mounting location.

The vertical centerline of the sign shall be centered with the door, or shall be in that half of the door, either the right or left, that contains the latch. In case of double-doors, both doors shall be marked and the signs shall be centered with the doors. Arrows may be omitted on door-mounted signs. Door-mounted signs shall comply with Figure S101.1(1) in Appendix S.

1025.2.6.1.2 Exit discharge doors.

At doors serving as exit discharge, a sign in compliance with Section 1025.2.6.1.1 shall contain supplemental directional text such as "FINAL EXIT", "EXIT THROUGH LOBBY", or "EXIT TO STREET" in sans serif letters one-half as high as the word EXIT. Exit discharge door sign shall comply with Figure S101.1(13) in Appendix S.
