2	Skin corrosion/irritation	Classification not possible	-	-	-	-	No data available
3	Serious eye damage/eye irritation	Classification not possible	-	-	-	-	No data available
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	-	-	-	-	Insufficient data available
6	Carcinogenicity	Not classified	-	-	-	-	Due to the fact that the substance is classified as Group 3 by IARC Suppl 7 (1987).
7	Reproductive toxicity	Classification not possible	-	-	-	-	No data available
8	Specific target organ toxicity - Single exposure	Category 3 （Narcotic effects）		Warning	H336: May cause drowsiness or dizziness (narcotic effects)	P304+P340: IF INHALED: Remove victim to fresh air and keep at rest in a position comfortable for breathing.

Based on the evidence from animal studies including "somnolency (general suppression of activity)" (RTECS (2006)).
9	Specific target organ toxicity - Repeated exposure	Classification not possible	-	-	-	-	Classification not possible due to the insufficiency 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）	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=1.9ppb of the crustacea (Daphnia magna) (AQUIRE, 2003).
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 was Category 1 and bio-accumulation was low (BCF=62 of (Z)-2-chloro-1-(2,4,5-trichlorophenyl)vinyl dimethyl phosphate; tetrachlorvinphos (Existing Chemical Safety Inspections Data)), and there was no rapidly degrading (the decomposition by BOD of (Z)-2-chloro-1-(2,4,5-trichlorophenyl)vinyl dimethyl phosphate; tetrachlorvinphos: 0% (Existing Chemical Safety Inspections Data)), it was classified into Category 1.
