GHS Classification Guidance for the Japanese Government

When a substance does not contain chemical groups mentioned in the column for “classifiable
chemical structure” in Table 2-1, the “classification result” should be “not applicable”.
Example:”Not applicable” in the class of “Organic Peroxides” (The substance in question is an
organic compound not containing –O–O– structure.)
When a substance falls under a highly prioritized class of hazards, it is designated as “not
applicable”.
2-2-6 Chemical groups related to explosibility
【GHS 2 nd revised edition】 (2.1.4.2.2(a))
(a) There are no chemical groups associated with explosive properties present in the molecule.
Examples of groups which may indicate explosive properties are given in Table A 6.1 in Appendix
6 of the UN Recommendations on the Transport of Dangerous Goods, Manual of Tests and
Criteria;
Examples of the chemical groups are as follows:
Unsaturated C–C bond Acetylenes, acetylides, 1,2–dienes
C–metals, N–metals Grignardreagents, organolithium compounds
Neighboring nitrogen atoms Azides, aliphatic azo compounds, diazonium salts, hydrazines,
sulfonyl hydrazides
Neighboring oxygen atoms Peroxides, ozonides
N–O Hydroxylamines, nitrate salts, nitrate esters, nitro compounds,
nitroso compounds, N–oxides, 1,2–oxazoles
N–halogen Chloroamines, fluoroamines
O–halogen Chlorates, perchlorates, iodosyl compounds
(UNRTDG:Manual of Tests and Criteria, Appendix 6, Table A6.19)
2-2-7 Chemical groups related to self-reactivity
【GHS 2 nd revised edition】 (2.8.4.2(a))
(a) There are no chemical groups present in the molecule associated with explosive or
selfreactive properties; examples of such groups are given in Tables A6.1 and A 6.2 in the A
ppendix 6 of the UN Recommendations on the Transport of Dangerous Goods, Manual of Tests
and Criteria;
