Except as otherwise specifically provided in this code, where more than one class of water-reactive solids and liquids is stored in the same control area, the maximum quantity allowed of each water-reactive solid or liquid shall be limited as follows: the maximum quantity shall be reduced by the maximum allowable quantity for each such solid or liquid by the proportion that such solid or liquid bears to the total quantity of water-reactive solid and liquid stored in the control area. The total of the proportional amounts shall not exceed 100 percent.
Indoor storage of water-reactive solids and liquids in amounts exceeding the maximum allowable quantity per control area indicated in FC Table 5003.1.1(1), shall be in accordance with FC 5001, 5003, 5004 and this chapter.
Storage of water-reactive solids and liquids shall be in a detached building when required by FC5003.8.2.
In addition to the provisions of FC5004.12, floors in storage areas for water-reactive solids and liquids shall be of liquid-tight construction.
Rooms or areas used for the storage of water-reactive solids and liquids shall be constructed in a manner which resists the penetration of water through the use of waterproof materials. Piping carrying water for other than sprinkler systems shall not be within such rooms or areas.
When Class 2 and/or Class 3 water-reactive solids and liquids are stored in areas protected by a sprinkler system, the materials shall be stored in closed water-tight containers.
Class 2 water-reactive solids and liquids shall not be stored in basements or other areas below grade unless such materials are stored in closed water-tight containers or tanks.
Indoor storage rooms, areas and buildings containing Class 2 or Class 3 water-reactive solids and liquids shall be provided with explosion control in accordance with FC911 and the construction codes, including the Building Code.
Rooms or areas for the storage of water-reactive solids and liquids shall be provided with smoke and heat venting in accordance with FC910 and the construction codes, including the Building Code.
Outdoor storage of water-reactive solids and liquids shall be within tanks or closed water-tight containers and shall be in accordance with FC 6704.2.2 through 6704.2.5
Class 3 water-reactive solids and liquids shall not be stored within 75 feet (22 860 mm) of buildings, lot lines, public streets, private roads or means of egress.
Outdoor storage of Class 1 and Class 2 water-reactive solids and liquids shall not be within 20 feet (6096 mm) of buildings, lot lines, public streets, private roads or means of egress. A 2-hour fire barrier wall without openings or penetrations, and extending not less than 30 inches (762 mm) above and to the sides of the storage area, is allowed in lieu of such distance. The wall shall either be an independent structure, or the exterior wall of the building adjacent to the storage area.
Aisle widths between piles shall not be less than one-half the height of the pile or 10 feet (3048 mm), whichever is greater.
Secondary containment shall be provided in accordance with FC5004.2.2.
Water-reactive solids and liquids in amounts exceeding the maximum allowable quantity per control area indicated in FC Table 5003.1.1(1) or 5003.1.1(3) shall be handled and used in accordance with FC 5001, 5003, 5005 and this chapter.
