Current through Register 2024 Notice Reg. No. 28, July 12, 2024
(a) A waste exhibits the characteristic of
				  ignitability if representative samples of the waste have any of the following
				  properties:
(1) it is a liquid, other than an
				  aqueous solution containing less than 24 percent alcohol by volume, and has a
				  flash point less than 60°C (140°F), as determined by a Pensky-Martens
				  Closed Cup Tester, using the test method specified in ASTM Standard D-93-79 or
				  D-93-80 (incorporated by reference, see section
				  66260.11), or a Setaflash Closed
				  Cup Tester, using the test method specified in ASTM Standard D-3278-78
				  (incorporated by reference, see section
				  66260.11), or as determined by an
				  equivalent test method approved by the Department pursuant to section
				  66260.21;
(2) it is not a liquid and is capable, under
				  standard temperature and pressure, of causing fire through friction, absorption
				  of moisture or spontaneous chemical changes and, when ignited, burns so
				  vigorously and persistently that it creates a hazard;
(3) It is an ignitable compressed gas.
(A) The term "compressed gas" shall designate
				  any material or mixture having in the container an absolute pressure exceeding
				  40 p.s.i. at 70 °F or, regardless of the pressure at 70 °F, having an
				  absolute pressure exceeding 104 p.s.i. at 130 °F; or any liquid flammable
				  material having a vapor pressure exceeding 40 p.s.i. absolute at 100 °F as
				  determined by ASTM Test D-323.
(B)
				  A compressed gas shall be characterized as ignitable if any one of the
				  following occurs:
1. Either a mixture of 13
				  percent or less (by volume) with air forms a flammable mixture or the flammable
				  range with air is wider than 12 percent regardless of the lower limit. These
				  limits shall be determined at atmospheric temperature and pressure. The method
				  of sampling and test procedure shall be acceptable to the Bureau of Explosives
				  and approved by the director, Pipeline and Hazardous Materials Technology, U.S.
				  Department of Transportation (see Note 2) or equivalent test methods approved
				  by the Department pursuant to section
				  66260.21.
2. Using the Bureau of Explosives' Flame
				  Projection Apparatus (see Note 1), the flame projects more than 18 inches
				  beyond the ignition source with valve opened fully. Or, the flame flashes back
				  and burns at the valve with any degree of valve opening.
3. Using the Bureau of Explosives' Open Drum
				  Apparatus (see Note 1), there is any significant propagation of flame away from
				  the ignition source.
4. Using the
				  Bureau of Explosives' Closed Drum Apparatus (see Note 1), there is any
				  explosion of the vapor-air mixture in the drum.
(4) It is an oxidizer. An oxidizer for the
				  purpose of this subchapter is a substance such as a chlorate, permanganate,
				  inorganic peroxide, or a nitrate, that yields oxygen readily to stimulate the
				  combustion of organic matter (see Note 4).
(A)
				  An organic compound containing the bivalent -O-O- structure and which may be
				  considered a derivative of hydrogen peroxide where one or more of the hydrogen
				  atoms have been replaced by organic radicals must be classed as an organic
				  peroxide unless:
1. The material meets the
				  definition of a Class A explosive or a Class B explosive, as defined in §
													66261.23(a)(8),
				  in which case it must be classed as an explosive.
2. The material is forbidden to be offered
				  for transportation according to
				  49 CFR
				  172.101 and
				  49 CFR
				  173.21.
3. It is determined that the predominant
				  hazard of the material containing an organic peroxide is other than that of an
				  organic peroxide, or
4. According
				  to data on file with the Pipeline and Hazardous Materials Safety Administration
				  in the U.S. Department of Transportation (see Note 3), it has been determined
				  that the material does not present a hazard in
				  transportation.
