PHYSICAL HAZARDS
Hazard class Classification Symbol Signal word Hazard statement Precautionary statement Rationale for the classification
1 Explosives Classification not possible - - - - According to IMDGC, the substance is explosive and sensitive to friction in a dry state. However, since its evaluation as an explosive is not obtainable, the substance was classified into the "Classification not possible" category. (The substance wetted with 30% water by mass is defined as Division 4.1, packing class I (UN 3376) by the UNRTDG, indicating it belongs to desensitized explosives.)
2 Flammable gases (including chemically unstable gases) Not applicable - - - - Solid (GHS definition)
3 Aerosols Not applicable - - - - Not aerosol products.
4 Oxidizing gases Not applicable - - - - Solid (GHS definition)
5 Gases under pressure Not applicable - - - - Solid (GHS definition)
6 Flammable liquids Not applicable - - - - Solid (GHS definition)
7 Flammable solids Classification not possible - - - - No data available.
8 Self-reactive substances and mixtures Classification not possible - - - - According to IMDGC, the substance is explosive and sensitive to friction in a dry state. In addition, the pure substance is self-reactive. Given this information, classification of the substance is not clear in accordance with GHS definition. Consequently, the substance was classified into the "Classification not possible" category.
9 Pyrophoric liquids Not applicable - - - - Solid (GHS definition)
10 Pyrophoric solids Classification not possible - - - - Its melting point is reported to be 158degC (Howard, 1997) and 156degC (Gangolli, 1994). However, due to insufficient data available, the substance was classified into the "Classification not possible" category. (These melting points were cited from Hazard Sheets.)
11 Self-heating substances and mixtures Classification not possible - - - - No data available.
12 Substances and mixtures which, in contact with water, emit flammable gases Not applicable - - - - The chemical structure of the substance does not contain metals or metalloids (B, Si, P, Ge, As, Se, Sn, Sb,Te, Bi, Po, At).
13 Oxidizing liquids Not applicable - - - - Solid (GHS definition)
14 Oxidizing solids Classification not possible - - - - No data available.
15 Organic peroxides Not applicable - - - - Containing no bivalent -O-O- structure in the molecule
16 Corrosive to metals Classification not possible - - - - No data available.

HEALTH HAZARDS

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 Classification not possible - - - - It is reported that an Ames test gave positive results (RTECS (accessed in July 2007)). However, since no other test results (in-vivo tests in particular) are available, classification is not possible.
6 Carcinogenicity Classification not possible - - - - No data available.
7 Reproductive toxicity Classification not possible - - - - No data available.
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.
