PHYSICAL HAZARDS
| Hazard class | Classification | Symbol | Signal word | Hazard statement | Precautionary statement | Rationale for the classification | |
|---|---|---|---|---|---|---|---|
| 1 | Explosives | Not applicable | - | - | - | - | There are no chemical groups associated with explosive properties present in the molecules. |
| 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 | - | - | - | - | Although fine powder tantalum is considered to be flammable (ICSC (2005)), since there is no data, it cannot be classified. |
| 8 | Self-reactive substances and mixtures | Not applicable | - | - | - | - | There are no chemical groups associated with explosive or self-reactive properties present in the molecule. |
| 9 | Pyrophoric liquids | Not applicable | - | - | - | - | Solid (GHS definition) |
| 10 | Pyrophoric solids | Classification not possible | - | - | - | - | While there is data of ignition point > 250 degC(ICSC (2005)), it is also indicated that fine powder has spontaneous combustibility (Bretherick (J), (5th, 1998)). Thus, it cannot be classified since there is no detailed data. |
| 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 classified | - | - | - | - | Since water solubility is measured, it is judged that it is stable in the water. |
| 13 | Oxidizing liquids | Not applicable | - | - | - | - | Solid (GHS definition) |
| 14 | Oxidizing solids | Not applicable | - | - | - | - | Inorganic compounds containing no oxygen and halogen. |
| 15 | Organic peroxides | Not applicable | - | - | - | - | Inorganic substance |
| 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 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: Mouse; ENDPOINT: LD50; VALUE: 595mg/kg; REFERENCE SOURCE: RTECS (2004) |
| 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 | 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. |
Since there is description of possibility of physical irritations (ICSC, 2005; SITTG, 4th, 2002), 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 | Classification not possible | - | - | - | - | No data available |
| 6 | Carcinogenicity | Classification not possible | - | - | - | - | There is old carcinogenicity tests reports using rat (conclusions is unclear, PATTY, 5th, 2001). But it is not estimated by the existing classifications of IARC, ACGIH, etc., and it cannot be classified due to insufficient data. |
| 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 ... |
It was set as Category 3 (respiratory irritative) from description (ACGIH-TLV, 2005; ICSC, 2005; HSDB, 2003; SITTIG, 4th, 2002) that inhalation indicates irritative. |
| 9 | Specific target organ toxicity - Repeated exposure | Classification not possible | - | - | - | - | Although a report shows that neither affect was seen in the workers exposed to the dust including tantalum (PATTY, 5th, 2001) nor affect by tantalum gauze (ACGIH, 7th, 2001-ATTY, 5th, 2001) was seen, it cannot be classified due to insufficient data. |
| 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） | Classification not possible | - | - | - | - | No data available |
| 11 | Hazardous to the aquatic environment （Long-term） | Classification not possible | - | - | - | - | No data available. |
