PHYSICAL HAZARDS

Hazard class		Classification	Pictogram Signal word	Hazard statement (code)	Precautionary statement (code)	Rationale for the classification
1	Explosives	*	- -	-	-	There is a chemical group associated with explosive properties (neighboring oxygen atoms) present in the molecule, but because it is classified in Division 5.1 in UNRTDG (UN1504), not applicable to explosives, hazards of the highest precedence, it was classified as "Not classified."
2	Flammable gases	*	- -	-	-	Solid (GHS definition). It was classified as "Not classified (Not applicable)."
3	Aerosols	*	- -	-	-	Not aerosol products. It was classified as "Not classified (Not applicable)."
4	Oxidizing gases	*	- -	-	-	Solid (GHS definition). It was classified as "Not classified (Not applicable)."
5	Gases under pressure	*	- -	-	-	Solid (GHS definition). It was classified as "Not classified (Not applicable)."
6	Flammable liquids	*	- -	-	-	Solid (GHS definition). It was classified as "Not classified (Not applicable)."
7	Flammable solids	*	- -	-	-	It was classified as "Not classified" from information that it is not combustible (ICSC (2005)).
8	Self-reactive substances and mixtures	*	- -	-	-	It was classified as "Not classified (Not applicable)" because it was classified as oxidizing solids.
9	Pyrophoric liquids	*	- -	-	-	Solid (GHS definition). It was classified as "Not classified (Not applicable)."
10	Pyrophoric solids	*	- -	-	-	It was classified as "Not classified" from information that it is not combustible (ICSC (2005)).
11	Self-heating substances and mixtures	*	- -	-	-	It was classified as "Not classified" from information that it is not combustible (ICSC (2005)).
12	Substances and mixtures which, in contact with water, emit flammable gases	*	- -	-	-	It contains a metal (Na), and it reacts vigorously with water (Hommel (1991)), but a formed gas (oxygen) is an oxidizing gas. Therefore, it was classified as "Not classified."
13	Oxidizing liquids	*	- -	-	-	Solid (GHS definition). It was classified as "Not classified (Not applicable)."
14	Oxidizing solids	Category 1	Danger	H271	P371+P380+P375 P306+P360 P370+P378 P210 P220 P280 P283 P420 P501	It was classified in Category 1 because it is classified in Division 5.1, PG I in UNRTDG (UN1504).
15	Organic peroxides	*	- -	-	-	Inorganic compound. It was classified as "Not classified (Not applicable)."
16	Corrosive to metals	*	- -	-	-	Classification is not possible because test methods applicable to solid substances are not available.
17	Desensitized explosives	*	- -	-	-	It was classified as "Not classified" because it is not desensitized by wetting, dilution, etc.

This GHS classification was conducted based on the information sources and the guidance for classification and judgement which are described in the GHS Classification Guidance for the Japanese Government etc. Using other literature, test results etc. as evidence and including different content from this classification result in a label or SDS are allowed.
Hazard statement and precautionary statement will show by hovering the mouse cursor over a code in the column of "Hazard statement" and "Precautionary statement," respectively. In the excel file, both the codes and statements are provided.
A blank or "-" in the column of "Classification" denotes that a classification for the hazard class was not conducted in the year.
An asterisk “*” in the column of “Classification” denotes that “Not classified (or No applicable)” and/or “Classification not possible” is applicable. Details are described in the column of “Rationale for the classification”. If no English translation is available for “Rationale for the classification,” please refer to the Japanese version of the results.
