Scope and Application.

This code applies to all flammable and combusti ble liquids except those that are solid at 100°F (37.8°C) or above.

Requirements for the safe storage and use of the great variety of flammable and combustible liquids commonly available depend primarily on their fire characteristics, particularly the flash point, which is the basis for the several classifications of liquids as defined in Section

It should be noted that the classification of a liquid can be changed by contamination. For example, filling a Class II liquid into a tank which last contained a Class I liquid can alter its classification, as can exposing a Class II liquid to the vapors of a Class I liquid via an intercom necting vapor line (see 2-2.6.4 and 2-3.5.6). Care shall be exercised in such cases to apply the requirements appropriate to the actual classification.

The volatility of liquids is increased by heating. When Class II or Class III liquids are heated above their flash points, ventilation and electrical classification may be necessary in the immediate area. 1-

Additional requirements may be necessary for the safe storage and use of liquids which have unusual burning characteristics, which are subject to self-ignition when exposed to the air, which are highly reactive with other substances, which are subject to explosive decom position, or have other special properties which dictate safeguards over and above those specified for a normal liquid of similar flash point classification.

In particular installations the provisions of this code may be altered at the discretion of the authority having jurisdiction after consideration of the special fea tures such as topographical conditions, barricades, walls, adequacy of building exits, nature of occupancies, proximity to buildings or adjoining property and character of construction of such buildings, capacity and construction of proposed tanks and character of liquids to be stored, nature of process, degree of private fire protection to be provided and the adequacy of facilities of the fire department to cope with flammable or combustible liquid fires.

Existing plants, equipment, buildings, structures and installations for the storage, handling, or use of flammable or combustible liquids which are not in strict compliance with the terms of this code may be continued in use at the discretion of the authority having jurisdiction provided they do not constitute a recognized hazard to life or adjoining property. The existence of a situation which might result in an explosion or sudden escalation of a fire, such as inadequate ventilation of confined spaces, lack of adequate emergency venting of a tank, failure to fireproof the supports of elevated tanks, or lack of drainage or dikes to control spills may constitute such a hazard.

This code shall not apply to:

Transportation of flammable and combustible liquids. These requirements are contained in the U.S. Department of Transportation regulations or in NEPA 385. Standard for Tank Vehicles for Flammable and Combustible Liquids.

Storage, handling and use of fuel oil tanks and containers connected with oil burning equipment. These requirements are covered separately in NFPA 31, Stan dard for the Installation of Oil Burning Equipment.

Storage of flammable and combustible liquids on farms and isolated construction projects. These requirements are covered separately in NFPA 395, Standard for the Storage of Flammable and Combustible Liquids on Farms and Isolated Construction Projects.

Liquids without flash points that can be flamemable under some conditions, such as certain halogenated hydrocarbons and mixtures containing halogenated hydrocarbons. (See NFPA 321, Standard on Bask Classification of Flammable and Combustible Liquids.)

Mists, sprays or foams. (Except flammable aerosols in containers, which are included in Chapter 4.)

Installations made in accordance with the applicable requirements of standards of the National Fire Protection Association: NFPA 32, Dry Cleaning Plants; NFPA 33, Sirray Application Using Flammable and Combustible Materials; NFPA 34, Dipping and Coating Processes Using Flammable or Combustible Liquids; NFPA 35, Manufacture of Organic Coatings; NFPA 36, Solvent Extraction Plants; NFPA 37, Installation and Use of Stationary Combustion Engines and Gas Turbines; NFPA 45, Fire Protection for Laboratories Using Chemicals; and Chapter 7 of NFPA 994984, Standard for Health Care Facilities, shall be deemed to be in compliance with this code.

Metrication. If a value for measurement as given in this standard is followed by an equivalent value in other units, the first stated is regarded as the requirement. The given equivalent value may be approximate.
