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. [For health hazards, refer also to hydrogen fluoride since it can react with water to produce hydrogen fluoride.]	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）
1	Acute toxicity (Dermal)	Classification not possible	- -	-	-	No data available. [For health hazards, refer also to hydrogen fluoride since the substance can react with water to produce hydrogen fluoride.]	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）
1	Acute toxicity (Inhalation: Gases)	Classification not possible	- -	-	-	Although a LC50 value of 2272 ppm for rats (RTECS (2009), original literature: Journal of Toxicological Sciences vol. 18,394 (1993)), classification was not possible since the exposure period was not clear. [For health hazards, refer also to hydrogen fluoride since it can react with water to produce hydrogen fluoride.] [Since it can react with water to produce hydrogen fluoride, refer to hydrogen fluoride for health hazards.]	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	- -	-	-	No data available. Careful handling of the substance is required based of the following reports: "corrosive for the skin and eye" (ICSC (J) (1997)) and "Silicon tetrafluoride can react with water to produce hydrogen fluoride and cause irritation" (PATTY (5th, 2001)).	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）
3	Serious eye damage/eye irritation	Classification not possible	- -	-	-	No data available. As relevant information, careful handling of the substance is required based of the following reports: "corrosive for the skin and eye" (ICSC (J) (1997)) and "Silicon tetrafluoride can react with water to produce hydrogen fluoride and cause irritation" (PATTY (5th, 2001)).	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）
4	Skin sensitization	Classification not possible	- -	-	-	No data available.	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）
5	Germ cell mutagenicity	Classification not possible	- -	-	-	Classification not possible due to lack of data. Although there is information from epidemiologic research where incidences of chromosome aberration and micronucleus in peripheral blood were increased in occupational exposure to both hydrofluoric acid and silicon tetrafluoride, the degree of silicon tetrafluoride contribution to the effects is uncertian.	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）
6	Carcinogenicity	Classification not possible	- -	-	-	No data available.	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）
7	Reproductive toxicity	Classification not possible	- -	-	-	No data available.	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）
8	Specific target organ toxicity - Single exposure	Classification not possible	- -	-	-	Classification not possible due to lack of data. As information in RTECS (2006) in List 3, there is a report that pulmonary edema and emphysema were observed in a rat acute toxicity test (inhalation), but the exposure period or details of the test were not clear. In EHC 36 (1984), the substance is reported as a "respiratory tract irritant" and symptoms by inhalation of hydrogen fluoride (HF) are reported. Since silicon tetrafluoride can react with water to produce hydrogen fluoride, careful handling of the substance is required.	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）
9	Specific target organ toxicity - Repeated exposure	Classification not possible	- -	-	-	No data available. As relevant information, there is information of skeletal fluorosis associated with the consumption of drinking-water containing fluoride (EHC 227 (2002)). In addition, since silicon tetrafluoride can react with water to produce hydrogen fluoride, careful handling of the substance is required.	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）
10	Aspiration hazard	Not classified (Not applicable)	- -	-	-	Gas (GHS definition)	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”.
