| 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 ... |
Based on a LD50 value of 0.8 g/kg for rats (PATTY (5th, 2001)), the substance was classified into Category 4. |
| 1 | Acute toxicity （Dermal） | Classification not possible | - | - | - | - | Classification not possible due to lack of data. As relevant information, a LDLo value is 1500 mg/kg (IUCLID (2002)). |
| 1 | Acute toxicity （Inhalation: Gases） | Not applicable | - | - | - | - | Liquid (GHS definition) |
| 1 | Acute toxicity （Inhalation: Vapours） | Classification not possible | - | - | - | - | Classification not possible due to lack of data. As relevant information, there is information of a LC50 value for rats of 930 ppm/4h (RTECS (2008)). Since the LC50 value was lower than 90% of saturated vapour pressure concentration (189,737 ppm), the test was considered to be conducted for vapour with almost no included mists. |
| 1 | Acute toxicity （Inhalation: Dusts and mists） | Classification not possible | - | - | - | - | No data available. |
| 2 | Skin corrosion/irritation | Category 1 |
|
Danger | H314: Causes severe skin burns and eye damage |
P301+P330+P331: IF SWALLOWED: Rinse mouth. Do NOT induce vomiting. P303+P361+P353: IF ON SKIN （or hair）: Remove/Take off immediately all contaminated clothing. Rinse skin with water/shower. P305+P351+P338: IF IN EYES: Rinse cautiously with water for several minutes. Remove contact lenses, if present and easy to do. Continue rinsing.

P305+P351+P338: IF IN EYES: Rinse cautiously with water for several minutes. Remove contact lenses, if present and easy to do. Continue rinsing. P280: Wear protective gloves/protective clothing/eye protection/face protection. P310: Immediately call a POISON CENTER or doctor/physician. |
Based on a result that the application of one drop test substance to the eye caused severe burns of cornea and eyelids in a rabbit test (HSDB (2002)), reports of "contact with liquid causes severe burns of the eye" and "vapours cause severe irritation of eyes" (HSDB (2002)) and corrosive to the skin, the substance was classified into Category 1. |
| 4 | Respiratory sensitization | Classification not possible | - | - | - | - | No data available. |
| 4 | Skin sensitization | Classification not possible | - | - | - | - | No data available. |

|
Warning | H371: May cause damage to organs (respiratory 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 ... |
The substance causes severe burns and exposure to vapour is harmful (HSDB (2002)). It is reported that inhalation of the substance causes severe irritation of throat and may cause lung injury. Inhalation exposure cannot be tolerated even at low concentrations or short contact times (HSDB (2002)). Additionally, it is reported that inhalation exposure may result in laryngitis, dyspnea and chest pain, bleeding and ulceration of nasal and oral mucosa, pulmonary edema, chronic bronchitis, and pneumonia (HSDB (2002)). Based on these information reported in a document in List 2, the substance was classified into Category 2 (respiratory system). As relevant information, there is a report of suffocation and cyanosis as observed symptoms after inhalation exposure to mice (GESTIS (access on Aug. 2009)), and these symptoms suggest effects on the respiratory system. |
| 9 | Specific target organ toxicity - Repeated exposure | Classification not possible | - | - | - | - | No 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） | Classification not possible | - | - | - | - | No data available. |
| 11 | Hazardous to the aquatic environment （Long-term） | Classification not possible | - | - | - | - | No data available. |
