1 4. Commodity Classification
I The commodities in storage within the stockroom are cartoned and uncartoned electronic
goods products such as iPods, Speakers, Computers and Laptop.
I The storage has been classified very conservatively as Group A Plastics/High Hazard
Commodity (Attachment #3).
I Based on a review of the plans for the facility, the maximum height of the storage is
approximately 12 feet. The stockroom is considered as high piled storage based on CFC
I 2302.1 Attachment #3).
Based on Table 2306.2 (Attachment #4) and above classification of the commodities, the
following requirements apply to the storage within the Stockroom of the facility:
1 4.1 .A u torn a tic Fire Sprinkler System
The following requirements are based on NFPA 13 (2002 Editions):

Please note that Apple agrees to maintain any foam packaging that is uncartoned on the
floor to a maximum storage height of 5 feet with no storage above.
Please not that the racks are treated and protected as multiple-row racks if aisles
separating are less than 3.5 feet (Attachment #5). Additionally based on CFC Section
23 08.2.2, the racks are required to be treated as racks with solid shelving when
applying the fire sprinkler protection in NFPA 13. However, there is no differentiation
in the protection required for racks with or without solid shelving for storage heights of
12 feet or less [considered "miscellaneous storage"] in NFPA 13.

6.1 Occupancy Separation
Per CBC 508.3.3 fire barrier walls are not required between B, M and S-i occupancies in a
sprinklered building (Attachment #14).
6.2 Storage Separation
I Per CFC Section 2306.3.2.1, the aggregate of all high-piled storage areas within a building
shall be used for the application of Table 2306.2 unless such areas are separated from each
other by 1-hour fire barrier walls constructed in accordance with the International Building I Code. Openings in such walls shall be protected by opening protective assemblies having a
1-hour fire protection rating (Attachment #14).
I Therefore to separate the Apple Inc suite from the adjacent tenant spaces, a 1-hour fire
barrier walls constructed in accordance with the International Building Code will be
required. Openings in such walls shall be protected by opening protective assemblies
I having a 1-hour fire protection rating.
The business owners agree to provide a minimum of 1-hour fire barrier wall in accordance I International Building Code between the Apple Inc suite and the adjacent tenant spaces.
6.3 Allowable Area ' The building is existing. There are no proposed changes to the overall building size,
construction, square footage or sideyards.

systems with multiple hazard classifications, the hose stream
demand shall be in accordance with one of the following:
(1) Add the hose demand for the highest hazard classifica-
tion within the system, or
(2) Add the hose demand for each individual hazard classifica-
tion to the calculations for the design area for that hazard, or
(3) For systems with multiple hazard classifications where the
higher classification only lies within single rooms less than
or equal to 400 ft2 in area with no such rooms adjacent,
add the hose demand for the principal occupancy for the
remainder of the system.
11.2.3.1.8 Restrictions. Regardless of which of the two meth-
ods is used, the following restrictions shall apply:
For areas of sprinkler operation less than 1500 ft2 (139 m°)
used for light and ordinary hazard occupancies, the density

SECTION 2304
DESIGNATION OF HIGH-PILED STORAGE AREAS
2304.1 General. High-piled storage areas, and portions of
high-piled storage areas intended for storage of a different
commodity class than adjacent areas, shall be designed and
specifically designated to contain Class I, Class II, Class Ill,
Class IV or high-hazard commodities. The designation of a
high-piled combustible storage area, or portion thereof
intended for storage of a different commodity class, shall be
based on the highest hazard commodity class stored except as
provided in Section 2304.2.
2304.2 Designation based on engineering analysis. The des-
ignation of a high-piled combustible storage area, or portion
thereof, is allowed to be based on a lower hazard class than that
of the highest class of commodity stored when a limited quan-
tity of the higher hazard commodity has been demonstrated by
engineering analysis to be adequately protected by the auto-
matic sprinkler system provided. The engineering analysis
shall consider the ability of the sprinkler system to deliver the
higher density required by the higher hazard commodity. The
higher density shall be based on the actual storage height of the
pile or rack and the minimum allowable design area for sprin-
kler operation as set forth in the density/area figures provided
in NFPA 13. The contiguous area occupied by the higher haz-
ard commodity shall not exceed 120 square feet (Ill m2) and
additional areas of higher hazard commodity shall be separated
from other such areas by 25 feet (7620 mm) or more. The sprin-
kler system shall be capable of delivering the higher density
282
over a minimum area of 900 square feet (84 1112) for wet pipe
systems and 1,200 square feet (II mt) for dry pipe systems.
The shape of the design area shall be in accordance with
Section 903.

2306.1 General. Fire protection and life safety features for
high-piled storage areas shall be in accordance with Sections
2306.2 through 2306.10.
2306.2 Extent and type of protection. Where required by
Table 2306.2, fire detection systems, smoke and heat removal,
draft curtains and automatic sprinkler design densities shall
extend the lesser of 15 feet (4572 mm) beyond the high-piled
storage area or to a permanent partition. Where portions of
high-piled storage areas have different fire protection require-
ments because of commodity, method of storage or storage
height, the fire protection features required by Table 2306.2
within this area shall be based on the most restrictive design
requirements.
2306.3 Separation of high-piled storage areas. High-piled
storage areas shall be separated from other portions of the
building where required by Sections 2306.3.1 through
2306.3.2.2.

MEANS OF EGRESS
1004.8 Outdoor areas. Yards, patios, courts and similar out-
door areas accessible to and usable by the building occupants
shall be provided with means of egress as required by this chap-
ter. The occupant load of such outdoor areas shall be assigned
by the building official in accordance with the anticipated use.
Where outdoor areas are to be used by persons in addition to the
occupants of the building, and the path of egress travel from the
outdoor areas passes through the building, means of egress
requirements for the building shall be based on the sum of the
occupant loads of the building plus the outdoor areas.
Exceptions:
Outdoor areas used exclusively for service of the
building need only have one means of egress.
Both outdoor areas associated with Group R-3 and in-
dividual dwelling units of Group R-2.
1004.9 Multiple occupancies. Where a building contains two
or more occupancies, the means of egress requirements shall
apply to each portion of the building based on the occupancy of
that space. Where two or more occupancies utilize portions of
the same means of egress system, those egress components
shall meet the more stringent requirements of all occupancies
that are served.
