PHYSICAL HAZARDS
| Hazard class | Classification | Symbol | Signal word | Hazard statement | Precautionary statement | Rationale for the classification | |
|---|---|---|---|---|---|---|---|
| 1 | Explosives | Classification not possible | - | - | - | - | Classification not possible due to lack of data. The substance could be classified as explosives since it contains nitrogen atoms adjacent to each other (Sulfonyl hydrazides) as chemical groups associated with explosive properties present and has oxygen balance calculated at -84.2, higher than -200 of the criteria. |
| 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 | Not classified | - | - | - | - | Non-combustible (ICSC (J) (1998)) |
| 8 | Self-reactive substances and mixtures | Classification not possible | - | - | - | - | S=O binding (sulfonyl hydrazides) is included as grouping in connection with autoreactive. Although this product is "the UN number 3226 self-reactivity substance D", in "ship safety laws", there is no data. So it cannot be classified. |
| 9 | Pyrophoric liquids | Not applicable | - | - | - | - | Solid (GHS definition) |
| 10 | Pyrophoric solids | Not classified | - | - | - | - | Non-combustible (ICSC (J), 1998) |
| 11 | Self-heating substances and mixtures | Not classified | - | - | - | - | Not combustible. (ICSC(J) (1998)) |
| 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 metaloids(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 | - | - | - | - | Classification not possible due to lack of data, though containing oxygen bonded to other than carbon and hydrogen. |
| 15 | Organic peroxides | Not applicable | - | - | - | - | Organic compounds containing no -0-0- structure |
| 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） | Category 5 | - | Warning | H303: May be harmful if swallowed | P312: Call a POISON CENTER or doctor/physician if you feel unwell. | SPECIES: Rat ENDPOINT: LD50 VALUE: 2300 mg/kg REFERENCE SOURCE: ACGIH (2001) |
| 1 | Acute toxicity （Dermal） | Classification not possible | - | - | - | - | It cannot be classified since there is only data of rabbit LD50 >200mg (ACGIH (2001)) and data is insufficient. |
| 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 | Not classified | - | - | - | - | Based on the report of having no skin stimulativeness on rabbits (ACGIH (2001)), it was classified as out of Category. |
| 3 | Serious eye damage/eye irritation | Category 2B | - | Warning | H320: Causes eye irritation |
P305+P351+P338: IF IN EYES: Rinse cautiously with water for several minutes. Remove contact lenses, if present and easy to do. Continue rinsing. P337+P313: If eye irritation persists: Get medical advice/attention. P264: Wash ... thoroughly after handling. |
Based on the slight report with being stimulative with the rabbit(ACGIH (2001)), it was set as Category 2B. |
| 4 | Respiratory sensitization | Classification not possible | - | - | - | - | No data available |
| 4 | Skin sensitization | Classification not possible | - | - | - | - | No data available |
| 5 | Germ cell mutagenicity | Not classified | - | - | - | - | Based on the negative report (ACGIH (2001)) for the in vivo somatic mutagenicity examination (micronucleus test which used mammalian erythrocytes), we classified it as Out Of Category according to the technical guideline. |
| 6 | Carcinogenicity | Classification not possible | - | - | - | - | No data available |
| 7 | Reproductive toxicity | Not classified | - | - | - | - | Based on the report of not observing effects on reproductive function of parent animals and on development anf groowth of next generation in rat administration test during premating to 4days nursing period (Health, Labor and Welfare Ministry reports (2005)), it was considered as on the outside of Category. |
| 8 | Specific target organ toxicity - Single exposure | Category 2 (nervous system) |
|
Warning | H371: May cause damage to organs (nervous system) |
P309+P311: IF exposed or if you feel unwell: Call a POISON CENTER or doctor/physician. P260: Do not breathe dust/fume/gas/mist/vapours/spray. P264: Wash ... thoroughly after handling. P270: Do not eat, drink or smoke when using this product. P405: Store locked up. P501: Dispose of contents/container to ... |
There is the description that there is nervous symptom such as tip toe gait and paralytic gait in rat 1000mg/kg oral administration test (Health, Labor and Welfare Ministry reports (2005)), it is classified into Category 2 (nervous system). |
| 9 | Specific target organ toxicity - Repeated exposure | Classification not possible | - | - | - | - | Insufficient data available |
| 10 | Aspiration hazard | Classification not possible | - | - | - | - | No data available |
| Hazard class | Classification | Symbol | Signal word | Hazard statement | Precautionary statement | Rationale for the classification | |
|---|---|---|---|---|---|---|---|
| 11 | Hazardous to the aquatic environment （Acute） | Category 2 | - | - | H401: Toxic to aquatic life |
P273: Avoid release to the environment. P501: Dispose of contents/container to ... |
It was classified into Category 2 from 48-hour EC50=2.9mg/L of Crustacea (Daphnia magna) (MOE eco-toxicity tests of chemicals, 2002). |
| 11 | Hazardous to the aquatic environment （Long-term） | Category 2 |
|
- | H411: Toxic to aquatic life with long lasting effects |
P273: Avoid release to the environment. P391: Collect spillage. P501: Dispose of contents/container to ... |
Classified into Category 2, since acute toxicity was Category 2 and not rapidly degrading (BOD: 2% (existing chemical safety inspections data)), though less bio-accumulative (BCF<3.0 (existing chemical safety inspections data)). |
