exit door (fig. 13). When traveling
in the egress direction, doors that lead
from a vertical exit, horizontal extension in a vertical exit, horizontal exit, supplemental
vertical exit, or exit passageway, but do not lead directly to the exterior or
to a street level lobby are intermediate exit doors.
Final
exit door (fig. 14). Doors leading
directly to the exterior or a street level lobby are
final exit doors.
2.2.9.1
Door signs. A photoluminscent
wall-mounted door sign complying with
2.1.1.2
shall be mounted on the wall adjacent to all intermediate and final exit doors.
At the final exit door, such sign shall contain supplemental directional text
in sans serif letters one-half as high as the word EXIT. Examples of such texts
are "FINAL EXIT", or "EXIT THROUGH LOBBY" or "EXIT TO STREET",
or "EXIT TO CHAMBERS STREET", etc. (see fig. 15).
2.2.9.2
Door Hardware markings. Door hardware
of all intermediate and final exit doors
shall be marked with no less than 16 in2 (406 mm2) of photoluminscent material.
This marking shall be located behind, immediately adjacent to, or on
the door handle and/or escutcheon. Where a panic bar is installed, such material
shall be no less than 1" (25 mm) wide for the entire length of the actuating
bar or touchpad. All hardware markings covered by 2.2.9.2 may include
ANSI Z535.1 safety green graphics such as arrows indicating door handle
turning directions, E001 or E002 emergency egress symbols as per ISO
7010, the word "EXIT", the word "PUSH", and similar egress-related symbols
provided the minimum 16 in2 (406 mm2) of photoluminscent material
is maintained.

Door frame markings. The top and
sides of the door frame of all intermediate
and final exit doors shall be marked with a solid and continuous 1"
to 2" (25 mm to 51 mm) wide stripe of photoluminscent material. Gaps are
permitted in the continuity of door frame markings where a line is fitted into
a corner or bend, but shall be as small as practicable and in no case greater
than 1" (25 mm).. Where the door molding does not provide enough flat
surface on which to locate the stripe, the stripes may be located on the wall
surrounding the frame. The dimensions, distances and locations of the required
markings shall be consistent and uniform on all doors on the route to the
exterior of the building.
2.3
General standards.
2.3.1
Design of door and directional signs. Unless
otherwise specified, all photoluminscent
door signs and directional signs referenced herein (see figs. 11, 15, 16,
17):
1.
may be either positive or negative image;
2.
shall be made with the non-photoluminscent portions of the signs in safety
green
as
per ANSI Z535.1-2002, American National Standard for Safety Color Code;
3.
shall include three components:
3.1
the word EXIT printed in sans serif letters at least 4? high (102 mm) with
strokes
no less than ½? (13 mm);
3.2
an emergency exit symbol at least 4? high (102 mm), complying with E001 or
E002
as per ISO 7010 (2003-10-01), Graphical Symbols—Safety Colours and
Safety
Signs—Safety Signs Used in Workplaces and Public Areas; and
3.3
an arrow at least 2 ¾? (70 mm) high, complying with E005 or E006 as per ISO
7010.
Exceptions:
1.
Arrows are not mandatory on door-mounted door signs required by 2.1.1.1.
2.
The word EXIT is not mandatory on directional signs required by 2.2.6 and 2.2.7.
3.
Additional descriptive text is permitted, provided such words are in sans serif
letters and, where
the word EXIT or emergency exit symbol is required on such sign, such
descriptive text
is no more than one-half as high as any the work EXIT or the emergency exit
symbol.
2.3.2
Solid and continuous. For the
purposes of this standard, 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. Nonetheless, photoluminscent materials shall be considered solid and
continuous if they occasionally contain the following safety green (ANSI
Z535.1) symbols
or text: 1) the word EXIT, 2) egress symbol E001 or E002 as per ISO 7010; 3)
direction arrows E005 or E006 as per ISO 7010, or other text or symbols as approved
by the Commissioner.
2.3.3
Consistent and uniform. Where
markings are required to be consistent and uniform throughout
the same exit, those portions of an exit in which the egress travel direction is
downward may be treated differently from those portions of the same exit in
which the
egress travel is upward.
2.3.4
Figures. The figures annexed are
intended only for illustration, and where there is a conflict
between the figures and the text, the text shall govern.
2.4
Good faith prior installations. The
Commissioner may accept variations to the required dimensions,
distances, returns (for side edge markings), locations, and MEA labeling for buildings
where: 1) photoluminscent materials were installed prior to January 1, 2005;
2) such
installations meet the intent of this standard. Applications for acceptance
shall indicate all
deviations from this standard. The commissioner shall require documentation
that the photoluminscent
materials installed achieve the equivalent brightness ratings as stated in 1.1.1
as well proof showing that the installation was completed prior to January 1,
2005. The commissioner
may require installation of additional photoluminscent signs or markings in order
to conform to the intent of this standard. Any such acceptance by the
commissioner shall
be annexed to the affidavit or report filed with the Department of Buildings
pursuant to 3.3,
and a copy of such report or affidavit including attachments shall be available
on the premises
for inspection by the Department of Buildings and Fire Department.
2.5
Installation of additional signs and markings. Where photoluminscent signs or markings are
installed in locations where they are not required by 2.1 and 2.2, such signs
and markings shall
be MEA-approved in accordance with 1.0 (technical specifications for minimum performance).
Examples of such other signs could include floor numbering signs, elevator landing
signs, elevator bank indicator signs, reentry signs, etc. Where door hardware
or door frame
markings in accordance with 2.2.9.2 or 2.2.9.3 are provided at reentry doors,
the reentry signs
required by the building code shall be photoluminscent and MEA-approved in accordance
with 1.0.
2.6
Other occupancies. Where
photoluminscent signs or markings are installed in the exit path in
other than Class E high rise buildings, such signs or markings shall comply
with this standard.
