FPN) The area classifications listed in Table 515-2 are based on the premise that the installation meets the applicable requirements of Elammable and Combustible Liquids Code, NFPA 30-1993 (ANSI), Chapter 5, in all respects. Should this not be the case, the authority havingjurisdiction has the authority to classify the extent of the classified space.

Several industry standards, codes, and company internal standards were used in developing the information in Table 1.2. These include internal company standards NFPA 30, Flammable and Combustible Liquids Code (Ref. 22) NFPA 59A. Liquefied Natural Gas (Ref. 23) API 2510, Design and Construction of Liquefied Petroleum Gas(LPG) Installations (Ref. 24) iRlnformation IM.2.5.2, Plant Layout and Spacing for Oil and Chemical Plants (Ref. 25), and Factory Mutual 7-44, Spacing of Facilities In Outdoor Chemical Plants (Ref. 26).

If the area under the vessel is provided with adequate drainage capability credit may also be taken for a reduced heat input due to the runoff of any flammable liquids producing the fire exposure. Usually drainage requirements to NFPA 30 (Flammable and Combustible Liquids Code), would have to be met, namely 1 percent to a 15.2 meter (50 ft.) radius. Published literature suggests that an uninsulated vessel rupture time could be increased 100% for a highly effective drainage system.
