Every order for the elimination of existing nonconformity shall allow a reasonable time for compliance therewith, consid- ering the nature of the work, the availability of labor and materials and needful prework preparation. Section 5. FLAMMABLE AND COMBUSTIBLE LIQUIDS DEFINED. "Flammable liquid" shall mean any liquid having a flash point below 140 F and having a vapor pressure not exceeding 40 pounds per square inch absolute at 100 F. "Combustible liquid" shall mean any liquid having a flash point above 140 F but below 200 F. Flash point shall mean the minimum temperature in degrees Fahr- enheit at which a liquid will give off flammable vapor as determined by appro- priate test procedure and apparatus as specified below. The flash point of liquids having a flash point at or below 175 F (79 C), except for fuel oils and certain viscous materials, shall be determined in accordance with the Standard Method of Test for Flash Point by Means of the Tag Closed Tester (A.S.T.M. D56-61). The flash point of liquids having a flash point at or above 175 F, except for fuel oils, shall be determined in accordance with the Standard Method for Flash Point by the Cleveland Open Cup Tester, ASTM D-92-57. The flash point of fuel oils and certain viscous materials having a flash point at or below 175 F shall be determined in accordance with the Standard Method of Test for Flash Point by Means of the Pensky-Martens Closed Tester (ASTM D-93-62). The volatility of liquids is increased when artificially heated to temperatures equal to or higher than their flash points. When so heated, Class II and III liquids shall be subject to the applicable requirements for Class I or II liquids. This ordinance shall also be applied to high flash point liquids when so heated even though these same liquids when not heated are outside of its scope. Section 6. CLASSIFICATION OF FLAMMABLE AND COMBUSTIBLE LIQUIDS. For the purpose of this ordinance, flammable liquids are divided into two classes: CLASS I shall include those having flash points at or below 100 F. CLASS II shall include those having flash points above 100 F but at or below 140 F. CLASS III (combustible liquids) shall include those having flash points above 140 F but below 200 F. Representative examples of these classes are: CLASS I CLASS II _ CLASS III Ether Benzol Nonane Turpentine Phenol Naphthalene Gasoline Acetone Amyl Alcohol Pine Oil Ethyl Alcohol Toluene Section 7.
