Storage of empty or idle combustible pallets inside an unprotected liquid storage area shall be limited to a maximum pile size of 2,500 square feet (232 m
2) and to a maximum storage height of 6 feet (1829 mm). Storage of empty or idle combustible pallets inside a protected liquid storage area shall comply with the requirements of NFPA 13, as modified by FC Appendix B. Pallet storage shall be separated from liquid storage by aisles with a minimum width of 8 feet (2438 mm).
5704.3.3.10 Containers in piles.
Containers in piles shall be stacked in such a manner as to provide stability and to prevent excessive stress on container walls. Adequate material-handling equipment shall be available to handle containers safely at the upper tier level.
5704.3.4 Quantity limits for storage.
Liquid storage quantity limitations shall comply with the requirements of FC 5704.3.4.1 through 5704.3.4.4.
5704.3.4.1 Maximum allowable quantity per control area.
For occupancies other than Group M wholesale and retail sales uses, indoor storage of flammable and combustible liquids shall not exceed the maximum allowable quantities per control area indicated in FC Table 5003.1.1(1) and shall not exceed the additional limitations set forth in this section. For Group M occupancy wholesale and retail sales uses, indoor storage of flammable and combustible liquids shall not exceed the maximum allowable quantities per control area indicated in FC Table 5704.3.4.1, except that no gasoline or flammable liquid motor fuel may be stored in portable containers for wholesale or retail sale. Storage of hazardous production material flammable and combustible liquids in Group H-5 occupancies shall be in accordance with FC Chapter 27.
Type of Liquid | Maximum Allowable Quantity Per Control Area (gallons) | ||
Sprinklered b per footnote densities and arrangements | Sprinklered per FC Tables 5704.3.6.3(4) through 5704.3.6.3(8) and FC Table 5704.3.7.5.1 and the construction codes, including the Building Code | Nonsprinklered | |
Class IA | 60 | 60 | 30 |
Class IB, IC, II and IIIA | 7,500 c | 15,000 c | 1,600 |
Class IIIB | Unlimited | Unlimited | 13,200 |
For SI: 1 foot = 304.8 mm, 1 square foot = 0.0929 m2, 1 gallon = 3.785 L, 1 gallon per minute per square foot = 40.75 L/min/m2.
a. Control areas shall be separated from each other by not less than a 1-hour fire barrier wall.
b. To be considered as sprinklered, a building shall be protected throughout by a sprinkler system with a design providing minimum densities as follows:
1. For uncartoned commodities on shelves 6 feet or less in height where the ceiling height does not exceed 18 feet, quantities are those allowed with a minimum sprinkler design density of Ordinary Hazard Group 2.
2. For cartoned, palletized or racked commodities where storage is 4 feet 6 inches or less in height and where the ceiling height does not exceed 18 feet, quantities are those allowed with a minimum sprinkler design density of 0.21 gallon per minute per square foot over the most remote 1,500-squarefoot area.
c. Where wholesale and retail sales or storage areas exceed 50,000 square feet in area, the maximum allowable quantities are allowed to be increased by 2 percent for each 1,000 square feet of area in excess of 50,000 square feet, up to a maximum of 100 percent of the table amounts. A control area separation is not required. The cumulative amounts, including amounts attained by having an additional control area, shall not exceed 30,000 gallons.
5704.3.4.2 Limitations on storage.
The quantity of flammable or combustible liquid stored shall be limited by occupancy as follows:
1. Group A, B, E, F, I and S occupancies. Flammable and combustible liquids shall be stored only for lawful uses incidental to the occupancy, including maintenance and operation of equipment, and in quantities not to exceed that which is necessary for such use.
2. Group M occupancies. Flammable and combustible liquids shall be stored only for lawful uses incidental to the occupancy, including maintenance and operation of equipment, and in quantities not to exceed that which is necessary for such use. The maximum allowable quantities for storage in wholesale and retail sales areas shall be in accordance with FC 5704.3.4.1.
3. Group R occupancies. Flammable and combustible liquids shall be stored only for maintenance and operation of equipment, and in quantities not to exceed that which is necessary for such use. Quantities within a dwelling unit shall be stored only for household use and in quantities below permit amounts. It shall be unlawful to store gasoline or other flammable liquid motor fuel within a dwelling unit.
4. Gasoline and other flammable liquid motor fuel. Storage of gasoline and other flammable liquid motor fuel in portable containers in quantities requiring a permit is subject to the approval of the commissioner, regardless of the occupancy classification of the premises.
5704.3.4.3 Quantities exceeding limits for control areas.
Quantities exceeding those allowed in control areas set forth in FC 5704.3.4.1 shall be stored in liquid storage rooms or liquid storage warehouses in accordance with FC 5704.3.7 and 5704.3.8.
5704.3.4.4 Liquids for maintenance and operation of equipment.
In all occupancies, quantities of flammable and combustible liquids requiring a permit pursuant to FC 105.6, used for maintenance purposes and the operation of equipment, shall be stored in liquid storage cabinets in accordance with FC 5704.3.2.
