Based on the rabbit LD50 (dermal route) value of 33mg/kg (RTECS (2006)). |
| 1 | Acute toxicity （Inhalation: Gases） | Not applicable | - | - | - | - | Due to the fact that the substance is a solid according to the GHS definition and inhalation of its gas is not expected. |
| 1 | Acute toxicity （Inhalation: Vapours） | Classification not possible | - | - | - | - | No data available |
| 1 | Acute toxicity （Inhalation: Dusts and mists） | Category 2 |
|

Based on the descriptions in the reports on rabbit skin irritation tests: "Moderate" (though the results are those of 24 (not 4) hour application) (RTECS (2006)) and "strongly irritating" (exposure duration unknown) (HSDB (2006)). The substance is thus considered a moderate skin irritant. |
| 3 | Serious eye damage/eye irritation | Category 2A |
|
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.

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. |
Based on the human evidence including "convulsions or effects on the convulsion threshold, changed locomotor activity and coma" (RTECS 2006), "Over 240 individuals reported symptoms such as eye and throat irritation, dizziness, and shortness of breath" (HSDB (2003)). As the referenced databases are assigned a priority rating of 2, these effects are classified into Category 2 (central nervous system) and Category 3 (respiratory irritation). |
| 9 | Specific target organ toxicity - Repeated exposure | Category 2 (salivary gland, respiratory system, nervous system) |
|
Warning | H373: May cause damage to organs through prolonged or repeated exposure (salivary gland, respiratory system, nervous system) |
P260: Do not breathe dust/fume/gas/mist/vapours/spray. P314: Get medical advice/attention if you feel unwell. P501: Dispose of contents/container to ... |
Based on the evidence from animal studies including "somnolency (reduced systemic activity), structural and functional changes in the salivary gland," "structural and functional changes in the trachea or bronchi" (RTECS (2006)). The effects on experimental animals were observed at dosing levels within the guidance value ranges for Categories 1 and 2. However, since the referenced databases are assigned a priority rating of 2, these effects are classified into Category 2 (salivary gland, respiratory organs, nervous system). |
| 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 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 hours EC50=0.055mg/L of the crustacea (Daphnia magna) (Agricultural Chemical Registration Data, 2004). |
| 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 ... |
Although acute toxicity is Category 1 and bio-accumulation is low (log Kow=0.94(PHYSPROP Database, 2005)), since there was no rapidly degrading (the decomposition by BOD: 0%(Existing Chemical Safety Inspections Data)), it was classified into Category 1. |
