PHYSICAL HAZARDS
| Hazard class | Classification | Symbol | Signal word | Hazard statement | Precautionary statement | Rationale for the classification | |
|---|---|---|---|---|---|---|---|
| 1 | Explosives | Not classified | - | - | - | - | Not used as explosives, though containing chemical groups associated with explosive properties present. |
| 2 | Flammable gases （including chemically unstable gases） | Not applicable | - | - | - | - | Solid (GHS definition) |
| 3 | Aerosols | Not applicable | - | - | - | - | Not aerosol products |

| 5 | Gases under pressure | Not applicable | - | - | - | - | Solid (GHS definition) |
| 6 | Flammable liquids | Not applicable | - | - | - | - | Solid (GHS definition) |
| 7 | Flammable solids | Classification not possible | - | - | - | - | Classification not possible due to lask of data, though the flash point is 174degC. |
| 8 | Self-reactive substances and mixtures | Classification not possible | - | - | - | - | Although it includes the grouping in connection with explosive and is understood as autoacceleration, it is not listed in the UN Recommendations. So it cannot be classified. |
| 9 | Pyrophoric liquids | Not applicable | - | - | - | - | Solid (GHS definition) |
| 10 | Pyrophoric solids | Not classified | - | - | - | - | Flash point: 174degC and considered as a non-pyrophoric substance at a room temperature |
| 11 | Self-heating substances and mixtures | Classification not possible | - | - | - | - | Test methods applicable to solid (melting point <= 140degC) substances are not 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 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 chlorine bonded to nitrogen. |
| 15 | Organic peroxides | Not applicable | - | - | - | - | Organic compounds containing no -0-0- structure |
| 16 | Corrosive to metals | Classification not possible | - | - | - | - | Test methods applicable are not available. Melting point: >55degC and solid |
| Hazard class | Classification | Symbol | Signal word | Hazard statement | Precautionary statement | Rationale for the classification | |
|---|---|---|---|---|---|---|---|
| 1 | Acute toxicity （Oral） | Category 4 |
|
Warning | H302: Harmful if swallowed |
P301+P312: IF SWALLOWED: Call a POISON CENTER or doctor/physician if you feel unwell. P264: Wash ... thoroughly after handling. P270: Do not eat, drink or smoke when using this product. P330: Rinse mouth. P501: Dispose of contents/container to ... |
Category 4 based on SPECIES: Rat; ENDPOINT: LD50; VALUE: 542 plus or minus 84mg/kg; REFERENCE SOURCE: ACGIH(2001) |
| 1 | Acute toxicity （Dermal） | Not classified | - | - | - | - | Since LD50 >20g/kg (RTECS (2004)) in rabbit dermal administration was over 5000mg/kg (percutaneous 2000mg/kg (Category 4) *2.5), it was set as the outside of Category. |
| 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） | Category 5 | - | Warning | H333: May be harmful if inhaled | P304+P312: IF INHALED: Call a POISON CENTER or doctor/physician if you feel unwell. | Since death was seen at rat 1 hour exposure tests: 20g/m3 (4 hour equivalent: 5mg/L (upper limit of Category 4)) (RTECS (2004)), it was set as Category 5. |
| 2 | Skin corrosion/irritation | Category 2 |
|
Warning | H315: Causes skin irritation |
P302+P352: IF ON SKIN: Wash with plenty of soap and water. P332+P313: If skin irritation occurs: Get medical advice/attention. P264: Wash ... thoroughly after handling. P280: Wear protective gloves/protective clothing/eye protection/face protection. P321: Specific treatment （see ... on this label）. P362: Take off contaminated clothing and wash before reuse. |
Though there is a result of "severe" on rabbit skin (RTECS (2004)), since there was no information about the irreversible impacts, it was classified as Category 2. |
| 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 | - | - | - | - | Classification not possible due to lack of data |
| 6 | Carcinogenicity | Classification not possible | - | - | - | - | No data available |
| 7 | Reproductive toxicity | Classification not possible | - | - | - | - | No data available |
| 8 | Specific target organ toxicity - Single exposure | Category 3 （Respiratory tract irritation） |
|
Warning | H335: May cause respiratory irritation (respiratory tract irritation) |
P304+P340: IF INHALED: Remove victim to fresh air and keep at rest in a position comfortable for breathing. P403+P233: Store in a well-ventilated place. Keep container tightly closed. P261: Avoid breathing dust/fume/gas/mist/vapours/spray. P271: Use only outdoors or in a well-ventilated area. P312: Call a POISON CENTER or doctor/physician if you feel unwell. P405: Store locked up. P501: Dispose of contents/container to ... |
Since a cough and a discomfort of breast was seen in human case (ACGIH (2001)), it is classified into Category 3 (respiratory irritation). |
| 9 | Specific target organ toxicity - Repeated exposure | Classification not possible | - | - | - | - | The symptom of the central nervous systems (CNS) has been observed in oral administration test to rats oral of 634kg/kg / 30 D-I (intermittent 30-day medication) (RTECS (2004)). Since this is over the guidance value, it is not adoptable. Since no additional data is available, it cannot be classified. |
| 10 | Aspiration hazard | Classification not possible | - | - | - | - | No data available on chemical pneumonia |
| 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 48-hour EC50=0.47ppm of Crustacea (Daphnia magna) (AQUIRE, 2003). |
| 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 ... |
Classified into Category 1, since acute toxicity was Category 1, supposed not rapidly degrading (BIOWIN), though supposed less bioaccumulative (log Kow=-0.94(PHYSPROP Database, 2005)). |
