§ 5704-03 Indoor and Aboveground Combustible Liquid Storage Systems.
RCNY § 5704-03
(a)Scope. This section sets forth requirements for the design and installation of indoor, aboveground combustible liquid storage systems, except fuel oil storage tanks and auxiliary storage tanks for oil-burning equipment regulated by the Mechanical Code, or to the installation of liquid motor fuel-dispensing storage tanks.
(b)General Provisions. Indoor aboveground combustible liquid storage tanks shall comply with the requirements of FC Chapters 50 and 57 and this section.
(c)Design and Installation Requirements.
(1)Location of tanks. Combustible liquid storage tanks shall preferably be installed on the floor at grade level. Combustible liquid storage tanks may also be installed on floors not more than two (2) floors below grade level.
(2)Fire-rated separation of tanks. (A) Combustible liquid storage tanks having an individual or aggregate capacity of more than 550 gallons but less than 1,100 gallons in a single control area shall be completely enclosed within noncombustible construction having at least a two (2) hour fire resistance rating. (B) Combustible liquid storage tanks having an individual or aggregate capacity of 1,100 gallons or more in a single control area shall be completely enclosed within noncombustible construction having at least a three (3) hour fire resistance rating.
(3)Sprinkler system protection. (A) Any floor below grade level upon which a combustible liquid storage tank is installed shall be protected throughout by a sprinkler system, except that that when the combustible liquid storage tank will only store a combustible liquid with a flash point of 200°F or greater, and the room or area is segregated, vertically and horizontally, from surrounding spaces by a fire separation of not less than two (2) hour fire resistance rating, only the room or area housing such tank need be protected by a sprinkler system.
(4)Piping systems. (A) General requirements.
(5)Pipe shafts shall not be penetrated by or contain other piping or ducts.
