HEALTH HAZARDS

Hazard class		Classification	Symbol	Signal word	Hazard statement	Precautionary statement	Rationale for the classification
1	Acute toxicity （Oral）	Not classified	-	-	-	-	SPECIES: Rat ENDPOINT: LD50 VALUE: 23160 mg/kg REFERENCE SOURCE: RTECS (2000)
1	Acute toxicity （Dermal）	Classification not possible	-	-	-	-	No data available
1	Acute toxicity （Inhalation: Gases）	Not applicable	-	-	-	-	Solid (GHS definition)
1	Acute toxicity （Inhalation: Vapours）	Classification not possible	-	-	-	-	No data available
1	Acute toxicity （Inhalation: Dusts and mists）	Classification not possible	-	-	-	-	No data available
2	Skin corrosion/irritation	Classification not possible	-	-	-	-	No data available
3	Serious eye damage/eye irritation	Classification not possible	-	-	-	-	No data available
4	Respiratory sensitization	Classification not possible	-	-	-	-	No data available
4	Skin sensitization	Classification not possible	-	-	-	-	No data available
5	Germ cell mutagenicity	Category 2		Warning	H341: Suspected of causing genetic defects	P308+P313: IF exposed or concerned: Get medical advice/attention. P201: Obtain special instructions before use. P202: Do not handle until all safety precautions have been read and understood. P281: Use personal protective equipment as required. P405: Store locked up. P501: Dispose of contents/container to ...	There were positive (RTECS (2000)) reports for the in vivo sister chromatid exchange tests using the mouse and for the in vitro Ames test. Therefore we classified it as Category 2.
6	Carcinogenicity	Category 2		Warning	H351: Suspected of causing cancer	P308+P313: IF exposed or concerned: Get medical advice/attention. P201: Obtain special instructions before use. P202: Do not handle until all safety precautions have been read and understood. P281: Use personal protective equipment as required. P405: Store locked up. P501: Dispose of contents/container to ...	Since it is classified into 2B according to IARC and classified into 2B in Japan Society for Occupational Health, it classified into 2.
7	Reproductive toxicity	Classification not possible	-	-	-	-	Classification not possible due to lack of data
8	Specific target organ toxicity - Single exposure	Classification not possible	-	-	-	-	No data available.
9	Specific target organ toxicity - Repeated exposure	Classification not possible	-	-	-	-	Although there is a report of liver and kidney enlargement in the examination of the rat out of the guidance value of Category 2(IARC (1987)), it cannot be classified due to lack of data.
10	Aspiration hazard	Classification not possible	-	-	-	-	No data available
