3	1,000	12,000	1,000	24,000
Combination 2 and 3	2,500	12,000	2,500	24,000

For SI: 1 foot = 304.8 mm, 1 pound = 0.454 kg, 1 square foot = 0.0929 m2.

a.   Sprinkler system protection and storage arrangements shall comply with the requirements of NFPA 30B. Sprinkler system protection shall extend 20 feet beyond the storage area containing the aerosol products.

b.   Storage quantities indicated are the maximum allowed in any 50,000-square-foot area.

5104.3.2 Segregated storage.

Storage of Level 2 and 3 aerosol products segregated into areas utilized exclusively for the storage of aerosols shall be in accordance with FC Table 5104.3.2 and FC 5104.3.2.1 and 5104.3.2.2.

Storage Separation	Maximum Segregated Storage Area a		Sprinkler Requirements
	Percentage of building area (percent)	Area limitation (square feet)
Separation area e, f	15	20,000	Notes b, c
Chain-link fence enclosure d	20	20,000	Notes b, c
1-hour fire-resistance-rated interior walls	20	30,000	Note b
2-hour fire-resistance-rated interior walls	25	40,000	Note b
3-hour fire-resistance-rated interior walls	30	50,000	Note b

For SI: 1 foot = 304.8 mm, 1 square foot = 0.0929 m2.

a.   The maximum segregated storage area shall be limited to the smaller of the two areas resulting from the percentage of building area limitation and the area limitation.

b.   Sprinkler system protection in aerosol product storage areas shall comply with the requirements of NFPA 30B and be approved. Other building areas not containing aerosol product storage shall be protected throughout by a sprinkler system in accordance with the construction codes, including the Building Code.

c.   Sprinkler system protection in aerosol product storage areas shall comply with the requirements of NFPA 30B and be approved. Sprinkler system protection shall extend a minimum 20 feet beyond the aerosol storage area.

d.   Chain-link fence enclosures shall comply with the requirements of FC 5104.3.2.1.

e.   A separation area shall be defined as an area extending outward from the periphery of the segregated aerosol product storage area as follows.

   1.   The limits of the aerosol product storage shall be clearly marked on the floor.

   2.   The separation distance shall be a minimum of 25 feet and maintained clear of all materials with a commodity classification greater than Class Ill in accordance with NFPA 13, as modified by FC Appendix B.

f.   Separation areas shall be allowed when approved.

5104.3.2.1 Chain-link fence enclosures.

Chain-link fence enclosures required by FC Table 5104.3.2 shall comply with the following requirements:

   1.   The fence shall not be less than No. 9 gauge steel wire, woven into a maximum 2-inch (51-mm) diamond mesh.

   2.   The fence shall be installed from the floor to the underside of the roof or ceiling above.

   3.   Class IV and high-hazard commodities shall be stored outside of the aerosol storage area and a minimum of 8 feet (2438 mm) from the fence.

   4.   Access openings in the fence shall be provided with either self-closing or automatic-closing devices or a labyrinth opening arrangement preventing aerosol containers from rocketing through the access openings.

   5.   Not less than two means of egress shall be provided from the fenced enclosure.

5104.3.2.2 Aisles.

The minimum aisle requirements for segregated storage in general purpose warehouses shall be in accordance with FC Table 5104.3.2.2.

FC Table 5104.3.2.2
Segregated Storage Aisle Widths and Distance to Aisles in General Purpose Warehouses

 

Storage Condition	Minimum Aisle Width (feet)	Maximum Distance from Storage to Aisle (feet)
Solid pile or palletized a	4 feet between piles	25
Racks with ESFR sprinklers a	4 feet between racks and adjacent Level 2 and 3 aerosol product storage	25
Racks without ESFR sprinklers a	8 feet between racks and adjacent Level 2 and 3 aerosol product storage	25

For SI: 1 foot = 304.8 mm.

a.   Sprinklers shall comply with the requirements of NFPA 30B.
