1 Acute toxicity （Oral） Classification not possible - - - - No data available
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 is the positive results by the chromosomal aberration test using a hamster marrow cell which are the in vivo mutagenicity test using a somatic cell, the micronucleus test using erythrocyte (EHC 202, 1998, IARC 32, 1983), and micronucleus test using rat erythrocyte (EHC 202, 1998). But there is no result positive by the in vivo heredity toxicity examination using a germ cell. So it is set as Category 2.
6 Carcinogenicity Category 1B Danger H350: May cause 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 ... 		It was classified into classified into B2 in EPA in 1994,. But it was classified into group 2A (IARC Suppl.7, 1987) in IARC, A2 (ACGIH 7th, 2001) in ACGIH, R (NTP RoC 11th, 2005) in NTP and the category 2 (EU-Annex I, 2005) in EU. So it was considered as Category 1B according to ACGIH which is recent report.
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 - - - - No data available
10 Aspiration hazard Classification not possible - - - - No data available
