PHYSICAL HAZARDS
| Hazard class | Classification | Symbol | Signal word | Hazard statement | Precautionary statement | Rationale for the classification | |
|---|---|---|---|---|---|---|---|
| 1 | Explosives | Classification not possible | - | - | - | - | Although the N-N group is included in chemical structure and the calculation value of oxygen balance is -183, classification is not possible with no data of onset of exothermic decomposition and decomposition energy. |
| 2 | Flammable gases （including chemically unstable gases） | Not applicable | - | - | - | - | Solid |
| 3 | Aerosols | Not applicable | - | - | - | - | Not aerosol products |
| 4 | Oxidizing gases | Not applicable | - | - | - | - | Solid |
| 5 | Gases under pressure | Not applicable | - | - | - | - | Solid |
| 6 | Flammable liquids | Not applicable | - | - | - | - | Solid |
| 7 | Flammable solids | Classification not possible | - | - | - | - | Classification not possible due to lack of data |
| 8 | Self-reactive substances and mixtures | Classification not possible | - | - | - | - | Although the N-N group is included in chemical structure, classification is not possible with no data. |
| 9 | Pyrophoric liquids | Not applicable | - | - | - | - | Solid |
| 10 | Pyrophoric solids | Classification not possible | - | - | - | - | Classification not possible due to lack of data |
| 11 | Self-heating substances and mixtures | Classification not possible | - | - | - | - | The test method applicable for substances becoming liquid or gas at 140degC of test temperature has not been established. |
| 12 | Substances and mixtures which, in contact with water, emit flammable gases | Not applicable | - | - | - | - | Metals or metalloids (B, Si, P, Ge, As, Se, Sn, Sb, Te, Bi, Po, At) are not included. |
| 13 | Oxidizing liquids | Not applicable | - | - | - | - | Solid |
| 14 | Oxidizing solids | Not applicable | - | - | - | - | Although it is an organic compound including chlorine, not fluorine and oxygen, this chlorine has not chemically bound to any elements other than carbon and hydrogen. |
| 15 | Organic peroxides | Not applicable | - | - | - | - | The organic compound not including peroxy group in molecule. |
| 16 | Corrosive to metals | Classification not possible | - | - | - | - | Test methods applicable to solid substances are not available. |
| Hazard class | Classification | Symbol | Signal word | Hazard statement | Precautionary statement | Rationale for the classification | |
|---|---|---|---|---|---|---|---|
| 1 | Acute toxicity （Oral） | Classification not possible | - | - | - | - | Classification not possible due to lack of data |
| 1 | Acute toxicity （Dermal） | Classification not possible | - | - | - | - | Classification not possible due to lack of data |
| 1 | Acute toxicity （Inhalation: Gases） | Not applicable | - | - | - | - | Since it was a solid by the definition of GHS and inhalation in gas was not assumed, it was classified into "Not applicable". |
| 1 | Acute toxicity （Inhalation: Vapours） | Classification not possible | - | - | - | - | Classification not possible due to lack of data |
| 1 | Acute toxicity （Inhalation: Dusts and mists） | Classification not possible | - | - | - | - | Classification not possible due to lack of data |
| 2 | Skin corrosion/irritation | Classification not possible | - | - | - | - | Although there is a description, " All Hydrazine show similar local effects depending on irritation conditions and its vapor is highly irritating to the skin", in the section for Effects on Human Health of HSDB (2004), classification is not possible because there is no data for this substance. Incidentally, [JD56] Hydrazine (CAS302-01-2) has been classified in Category 1A-1C and [ID245] Methylhydrazine (CAS60-34-4) and Phenylhydrazine (CAS100-63-0) in Category 2. |
| 3 | Serious eye damage/eye irritation | Classification not possible | - | - | - | - | Although there is a description of " All Hydrazine show a similar local effect by its stimulative aspect and the vapor is highly irritating for an eye." in the clause of the human healthy influence of HSDB (2004), since there is no data as this substance, classification is not possible. In addition, [ID 56] Hydrazine (CAS302-01-2) is classified into Category 1, and [ID 245] Methylhydrazine (CAS60-34-4) and [ID 907] Phenyl hydrazine (CAS100-63-0) are classified into Category 2A. |
| 4 | Respiratory sensitization | Classification not possible | - | - | - | - | Classification is not possible since there is no data. |
| 4 | Skin sensitization | Classification not possible | - | - | - | - | Classification is not possible since there is no data. |
| 5 | Germ cell mutagenicity | Classification not possible | - | - | - | - | Classification not possible due to lack of data |
| 6 | Carcinogenicity | Classification not possible | - | - | - | - | Since no evaluation by major international evaluation agencies is made and there is no data, classification is not possible. In addition, 1,2-Dimethylhydrazine which is an analogue is classified in group 2A by IARC (IARC 71 (1999)). |
| 7 | Reproductive toxicity | Classification not possible | - | - | - | - | Classification not possible due to lack of data |
| 8 | Specific target organ toxicity - Single exposure | Classification not possible | - | - | - | - | Classification not possible due to lack of data |
| 9 | Specific target organ toxicity - Repeated exposure | Classification not possible | - | - | - | - | Classification not possible due to lack of data |
| 10 | Aspiration hazard | Classification not possible | - | - | - | - | Classification not possible due to lack of data |
| Hazard class | Classification | Symbol | Signal word | Hazard statement | Precautionary statement | Rationale for the classification | |
|---|---|---|---|---|---|---|---|
| 11 | Hazardous to the aquatic environment （Acute） | Category 1 |
|
Warning | H400: Very toxic to aquatic life |
P273: Avoid release to the environment. P391: Collect spillage. P501: Dispose of contents/container to ... |
It was classified into Category 1 from 96 hours LC50=0.1mg/L of the fish (Oryzias Latipes) (Environmental Agency eco-toxicity tests of chemicals (1999)). |
| 11 | Hazardous to the aquatic environment （Long-term） | Category 1 |
|
Warning | H410: Very toxic to aquatic life with long lasting effects |
P273: Avoid release to the environment. P391: Collect spillage. P501: Dispose of contents/container to ... |
Since acute toxicity was Category 1 and there were no rapid degradability (not readily degradable, the decomposition by BOD: 0%(Existing Chemical Safety Inspections Data (1987))), it was classified into Category 1. |
