NFPA 30 15,000 Gallon Tank

[MechEng2007]

Hello,

I am working on a project that has a few carbon-steel tanks that hold motor oil (Class IIIB). Each tank is approximately 12,000 to 16,000 gallons. Why doesn't NFPA 30 provide sprinkler protection design information? Protection schemes are provided for "portable" tanks, but these have a maximum volume of 660 gallons.

Does 22.8.2 (NFPA 30, 2012 edition) allow standard sprinkler coverage?

Thank you.

Look at NFPA 13 for the sprinkler coverage required based upon what is in the area.

NFPA 30: Flammable and Combustible Liquids Code

What does NFPA 30 address?

Topics covered include fire and explosion prevention and risk control, storage of liquids in containers, storage of liquids in tanks, piping systems, processing facilities, bulk loading and unloading, and wharves.

NFPA 30: Document Scope
1.1 Scope. 1.1.1* This code shall apply to the storage, handling, and use of flammable and combustible liquids, including waste liquids, as herein defined and classified. A.1.1.1 This code is recommended for use as the basis for legal regulations. Its provisions are intended to reduce the hazard to a degree consistent with reasonable public safety, without undue interference with public convenience and necessity, of operations that require the use of flammable and combustible liquids. Compliance with this code does not eliminate all hazards in the use of flammable and combustible liquids. (See the Flammable and Combustible Liquids Code Handbook for additional explanatory information.) 1.1.2 This code shall not apply to the following: (1)*Any liquid that has a melting point of 100°F (37.8°C) or greater A.1.1.2(1) Liquids that are solid at 100°F (37.8°C) or above, but are handled, used, or stored at temperatures above their flash points, should be reviewed against pertinent sections of this code. (2)*Any liquid that does not meet the criteria for fluidity given in the definition of liquid in Chapter 3 and in the provisions of Chapter 4 A.1.1.2(2) The information in A.1.1.2(1) also applies here. (3) Any cryogenic fluid or liquefied gas, as defined in Chapter 3 (4)*Any liquid that does not have a flash point, but which is capable of burning under certain conditions A.1.1.2(4) Certain mixtures of flammable or combustible liquids and halogenated hydrocarbons either do not exhibit a flash point using the standard closed-cup test methods or will exhibit elevated flash points. However, if the halogenated hydrocarbon is the more volatile component, preferential evaporation of this component can result in a liquid that does have a flash point or has a flash point that is lower than the original mixture. In order to evaluate the fire hazard of such mixtures, flash point tests should be conducted after fractional evaporation of 10, 20, 40, 60, or even 90 percent of the original sample or other fractions representative of the conditions of use. For systems such as open process tanks or spills in open air, an open-cup test method might be more appropriate for estimating the fire hazard. (5)*Any aerosol product A.1.1.2(5) See NFPA 30B, Code for the Manufacture and Storage of Aerosol Products. (6) Any mist, spray, or foam (7)*Transportation of flammable and combustible liquids as governed by the U.S. Department of Transportation A.1.1.2(7) Requirements for transportation of flammable and combustible liquids can be found in NFPA 385, Standard for Tank Vehicles for Flammable and Combustible Liquids, and in the U.S. Department of Transportation’s Hazardous Materials Regulations, Title 49, Code of Federal Regulations, Parts 100–199. (8)*Storage, handling, and use of fuel oil tanks and containers connected with oil-burning equipment A.1.1.2(8) See NFPA 31, Standard for the Installation of Oil- Burning Equipment. (9)*Use and installation of alcohol-based hand rub (ABHR) dispensers A.1.1.2(9) Requirements for the use and installation of alcohol-based hand rubs are covered in NFPA 1, Fire Code, and NFPA 101, Life Safety Code.
