2-3-3 Flammable Aerosols (1)Definitions Definitions of flammable of aerosols in UN GHS are as follows, and they are adopted in this guidance. 【GHS 2 nd revised edition】(2.3.1) Aerosols, this means aerosol dispensers, are any non-refillable receptacles made of metal,glass or plastics and containing a gas compressed, liquefied or dissolved under pressure, with or w ithout a liquid, paste or pow der, and fitted with a release device allowing the contents to be ejected as solid or liquid particles in suspension in a gas, as a foam, paste or powder or in a liquid state or in a gaseous state. (2) Classification criteria in GHS 【GHS 2 nd revised edition】 (2.3.2) 2.3.2.1 A erosols should be considered for classification as flammable if they contain any component which is classified as flammable according to the GHS criteria, i.e.: Flammable liquids (see Chapter 2.6); Flammable gases (see Chapter 2.2); Flammable solids (see Chapter 2.7). NOTE: Flammable components do not cover pyrophoric, self-heating or water-reactive substances and mixtures because such components are never used as aerosol contents. 2.3.2.2 A flammable aerosol is classified in one of the two categories for this Class on the basis of its components, of its chemical heat of combustion and, if applicable, of the results of the foam test (for foam aerosols) and of the ignition distance test and enclosed space test (for spray aerosols). See decision logic in 2.3.4.1. (2.3.4.1 Decision logic) To classify a flammable aerosol, data on its flammable components, on its chemical heat of combustion and, if applicable, the results of the foam test (for foam aerosols) and of the ignition distance test and enclosed space test (for spray aerosols) are required. The GHS classification criteria are summarized as follows: Category 1:・aerosols whose content of flammable components is 85% or more and whose heat of combustion is 30 kJ/g or larger, or ・spray aerosols for which ignition occurs at a distance of 75 cm or more in the 44
flame distance (ignition distance) test, or ・foam aerosols which have, in the foam test, 20 cm or more of the flame height and 2 seconds or longer of the flame duration or have 4 cm or more of the flame height and 7 seconds or longer of the flame duration, Category 2:・spray aerosols for which the heat of combustion is 20 kJ/g or larger and either for which ignition occurs at a distance of 15 cm or more in the flame distance (ignition distance) test or for which the time equivalent is 300 second/ m 3 or less, or the deflagration density is 300 g/ m 3 or less, in the enclosed space ignition test, ・foam aerosols which have, in the foam test, 4 cm or more of the flame height and 2 seconds or longer of the flame duration, Not classified:aerosols whose content of flammable components is 1% or less and the heat of combustion is smaller than 20 kJ/g. (3) Guidance for Classification A) Judgment of “Not applicable” In classification of a pure substance, regarding “flammable aerosols”, “classification result” shall be “Not applicable”, and “not an aerosol product” shall be indicated for “Classification Grounds and Problems”. B) Judgment of “Not classified” A product which has no flammable components or whose flammable components is 1% or less and whose heat of combustion smaller than 20 kJ/g shall be “Not classified”. (4) Data availability The composition of an aerosol product is determined by its product designer. The categories of spray solutions and propellant gases should be determined according to the decision logic in GHS 2.3.4.1. if they meet the GHS classification criteria, with necessary test, if any. (5) Comparison with conventional classification systems A judging method described in the Special provision 63 for UN number 1950 (Aerosols) in UNRTDG 3.2.1 Dangerous Goods List has been adopted. (6) Sources of information for classification results under conventional systems For each of manufactured products, tests according to the GHS criteria must be performed. 45
