A. Installation Tolerances: Align metal wall backup panel system within installed tolerance
of 1/4 inch in 20 feet (6 mm in 6.1 m), noncumulative, on level and plumb and location
lines as indicated and within 1/8 inch (3 mm) offset of adjoining faces and of alignment
of matching profiles.
A. Remove temporary protective coverings and strippable films, if any, as metal panels
are installed, unless otherwise indicated in manufacturer's written installation
instructions. On completion of metal panel installation, clean finished surfaces as
recommended by metal panel manufacturer. Maintain in a clean condition during
construction.
B. After metal panel installation, clear weep holes and drainage channels of obstructions,
dirt, and sealant.

SPECIAL DETAILED REQUIREMENTS BASED ON USE AND OCCUPANCY
constructed with a fire barrier or fire wall would con-
stitute an exit (see Section 1025); however, moving
through a smoke barrier into another smoke compart-
ment is not a horizontal exit and therefore corridor
continuity must be maintained on both sides of the
smoke barrier.
To address the various operational requirements of
occupancies classified as Group 1-2, the code
includes provisions that both permit various areas to
be open to corridors and address suite arrangements
of the exit access portions of the facilities. Standards
for areas open to corridors are covered primarily in
this chapter. The design of suites is regulated by pro-
visions found in Section 407.4.3.
For the ease of operations of hospitals, it is often
desirable to have certain areas open to exit access
corridors. Recognizing these needs and that such
areas are equipped throughout with an automatic
sprinkler system, the code permits specific areas to
be open to corridors, provided they are properly
arranged and equipped with compensating protection
features (e.g., automatic fire detection). Sections
407.2.1 through 407.2.4 identify those areas and the
protection features required to maintain the safety of
the corridor.
In addition to practical reasons, such as in the case
of care providers' stations, it is also desirable to des-
ignate certain areas being open to the corridor for
treatment purposes. In many instances, the care
recipient is encouraged to leave the sleeping room for
both physical as well as social benefit. So that care
recipients can be encouraged to socialize and benefit
from group activities and social interaction, the areas
need to be open to the corridor.
Such waiting areas also serve a useful purpose
during a fire emergency. If evacuation becomes nec-
essary, care recipients usually will be relocated to an
adjacent smoke compartment in which the areas
open to the corridor will serve as a refuge area. Sec-
tion 407.5.1 contains provisions for the net area that
must be available for the relocation of care recipients.
Waiting areas provide a space in which care recipi-
ents can be relocated such that treatment can con-
tinue during a fire emergency.
407.2.1 Waiting and similar areas. Waiting areas and simi-
lar spaces constructed as required for corridors shall be per-
mitted to be open to a corridor, only where all of the
following criteria are met:
1. The spaces are not occupied as care recipient's sleeping
rooms, treatment rooms, incidental uses in accordance
with Section 509, or hazardous uses.
2. The open space is protected by an automatic fire detec-
tion system installed in accordance with Section 907,
3. The corridors onto which the spaces open, in the same
smoke compartment, are protected by an automatic fire
detection system installed in accordance with Section
907, or the smoke comparonent in which the spaces are
located is equipped throughout with quick -response
sprinklers in accordance with Section 903.3.2.

4. The space is arranged so as not to obstruct access to the
required exits.
f• In the design of health care facilities, it is desirable to
have small waiting areas and similar spaces open to
the corridor. Such seating areas or gathering spaces
provide care recipients and others a place to sit out-
side of the sleeping rooms or to wait near special
care areas for their turn in a treatment room. In con-
sideration of the additional protection features speci-
fied, small waiting areas and similar spaces are
permitted to be open to corridors in Group 1-2 occu-
pancies within each smoke compartment provided
they are constructed to the corridor standards for
Group 1-2 occupancies, as specified in Section 407.3.
Care recipient sleeping rooms, treatment rooms, as
well as hazardous and incidental use areas, cannot
be open to the corridors under this section. This con-
figuration is commonly found in a typical ward situa-
tion. The exception would be treatment areas for
psychiatric wards addressed in Section 407.2.3 and
the care suite provisions in Section 407.4.3. Areas
similar to waiting rooms could include common visit-
ing areas, reception or information stations and
patient check-in stations. General hospital office
areas or support spaces beyond those associated
with waiting or reception areas must separated from
the corridor (see Figure 407.2.1).
To reduce the likelihood that a fire within such an
open space could develop beyond the incipient
stage, thereby jeopardizing the integrity of the corri-
dor, the area is to be equipped with an automatic fire
detection system (see Section 907). The detectors
are to be located so as to provide the appropriate
coverage to the space.
There is no size limit set by the code for these
spaces. Due to the unlimited size of the space and
consequently the potential for a significant number of
people in the area, an automatic fire detection system
is also required in all corridors open to the spaces
within the smoke compartment, or the smoke com-
partment in which such spaces are located must be
protected throughout with quick -response sprinklers.
Waiting areas and similar spaces open to corridors
must be arranged so as to not obstruct access to
exits. There must be a clear path of travel of the mini-
mum required width for the corridor, which should be
maintained at all times. As such, furniture layouts
-must be arranged in a manner that obstruction of the
807.2.2 Care providers' stations. Spaces for care provid-
ers', supervisory staff, doctors' and nurses' charting, cormnu-
itications and related clerical areas shall be permitted to be
open to the corridor, where such spaces are constructed as
required for corridors.
Stations for care providers need to be located to pro-
vide quick access to care recipients and to permit
visual or audible monitoring of the sleeping rooms.
For these and other practical reasons, care providers'
stations are permitted to be open to the corridor, pro-
vided the walls surrounding the area are constructed
as required for corridor walls (see Figure 407.2.2).

SPECIAL DETAILED REQUIREMENTS BASED ON USE AND OCCUPANCY
Except as required in Section 407.8, the additional
protection of automatic fire detection is not required
because of the reduced risk to life safety and atten-
dance by the staff (see Section 407.8). This section is
not intended to apply to nurses' offices, administra-
tive supply storage areas, drug distribution stations or
similar areas with a higher fuel load and from which
