Based on the description in the report on rabbit skin irritation tests (ACGIH (7th, 2001)): "The substance produced severe skin irritation." Also based on the description in the report on guinea pig skin irritation tests: "severe erythema and edema were observed." Although the substance, as a severe skin irritant, is classified into Category 1-2 in the absence of data on reversibility, it should be placed in Category 1 from the viewpoint of safety. | |

Based on the human evidence including "obstructive impairment of pulmonary function" (MOE Risk Assessment vol. 2 (2003)), and the evidence from animal studies including "respiratory effects with tremor and spasm, severe pulmonary congestion and edema" (CERI Hazard Data 2000-48 (2001)). The effects on experimental animals were observed at dosing levels within the guidance value ranges for Category 1. | |

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 ... |
Since a potential that relevant toxicity was discovered in the water solubility (0.121mg/L(PHYSPROP Database, 2005)) of this substance cannot be denied from 96-hour LC50=1.2mg/L of tthe fish (Zebrafish) (CERI Hazard Data, 2002), it was classified into Category 1. | |
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=2.14(CERI Hazard Data, 2002)), since there was no rapidly degrading (the decomposition by BOD: 0%(Existing Chemical Safety Inspections Data)), it was classified into Category 1. |
