---|---|---|---|---|---|---|---|
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: 3150 mg/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 | - | - | - | - | Since most vapor pressure of this product can be disregarded, it is thought that the inhalation study was done with the dust. There was no study in which LC50 was obtained. So data was insufficient, it cannot be classified. |
2 | Skin corrosion/irritation | Category 3 | - | Warning | H316: Causes mild skin irritation | P332+P313: If skin irritation occurs: Get medical advice/attention. | It was classified as Category 3 based on the statements that erythema emerged on rabbit and disappeared several days afterward (ACGIH (2001)) and that it stimulates the human skin (ICSC (J) (1996)). |
3 | Serious eye damage/eye irritation | Category 2A-2B | Warning | H319: Causes serious 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. P280: Wear protective gloves/protective clothing/eye protection/face protection. |
Based on statements that conjunctivitis was produced for the animal (ACGIH (2001)), and that an eye was stimulated (ACGIH and (2001), (ICSC (J), (1996)) and redness and pains were produced (ICSC (J), (1996)) in human, it was set as Category 2A-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 | - | - | - | - | 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 ... |
The symptom which indicates respiratory irritation, such as a irritation of nose and throat, a cough, stuffiness, and a throat pain in humans (ACGIH (2001), ECETOC TR63 (1995), ICSC (J) (1996), and HSDB (2005)), and it is classified into Category 3 (respiratory irritation). | |
9 | Specific target organ toxicity - Repeated exposure | Classification not possible | - | - | - | - | Classification not possible due to lack of 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) | Not classified | - | - | - | - | It carried out the outside of Category from 48-hour EC50=370-490mg/L (diboron trioxide concentration equivalent: 2382-3155 mg/L) of Crustacea (Daphnia magna) (IUCLID, 2000). |
11 | Hazardous to the aquatic environment (Long-term) | Not classified | - | - | - | - | Since not water-insoluble (aqueous solubility =27700 mg/L (HSDB, 2004)) and acute toxicity is low. |
