HEALTH HAZARDS

Hazard class		Classification	Pictogram Signal word	Hazard statement (code)	Precautionary statement (code)	Rationale for the classification	Classification year (FY)	GHS Classification Guidance for the Japanese Government
1	Acute toxicity (Oral)	Classification not possible	- -	-	-	No data available.	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）
1	Acute toxicity (Dermal)	Classification not possible	- -	-	-	No data available.	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）
1	Acute toxicity (Inhalation: Gases)	Classification not possible	- -	-	-	Although LC50 values are 250 ppm and 375 ppm (IUCLID (2000)) for rats, classification was not possible since these values were based on 10-minute exposure tests.	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）
1	Acute toxicity (Inhalation: Vapours)	Not classified (Not applicable)	- -	-	-	Gas (GHS definition)	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）
1	Acute toxicity (Inhalation: Dusts and mists)	Not classified (Not applicable)	- -	-	-	Gas (GHS definition)	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）
2	Skin corrosion/irritation	Classification not possible	- -	-	-	Although there is a report of strong irritant to skin (HSDB (2005)), the substance is a gas and the detailed data including test conditions such as application procedure, exposure period, and the degree and duration of skin irritating signs are not clear. Classification is not possible due to lack of the details.	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）
3	Serious eye damage/eye irritation	Classification not possible	- -	-	-	Although there is a result of irritative for the eyes of a monkey following exposure for 4-hour (DFGOT vol. 20 (2003)) and a report of irritating to the eye (HSDB (2005)), the substance was classified as "Classification not possible" since the substance is a gas and the test procedures for the reported results are unknown.	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）
4	Respiratory sensitization	Classification not possible	- -	-	-	No data available.	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）

Although there are reports of tremors and ptosis in monkeys (PATTY (5th, 2001)), the effects on the central nervous system was probably induced by lack of oxygen (DFGOT vol. 20 (2003)). For humans, there are reports suggesting respiratory tract irritation such as cough and irritant to mucous membranes (HSDB (2005)) and a report of lung damage such as pulmonary oedema and respiratory distress (ICSC (J) (1997), HSDB (2005)). Based on the information, the substance was classified into Category 1 (respiratory system).	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）

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”.
