Hazard class | Classification | Symbol | Signal word | Hazard statement | Precautionary statement | Rationale for the classification | |
---|---|---|---|---|---|---|---|
1 | Acute toxicity (Oral) | Not applicable | - | - | - | - | Gas (GHS definition) |
1 | Acute toxicity (Dermal) | Not applicable | - | - | - | - | Gas (GHS definition) |
1 | Acute toxicity (Inhalation: Gases) | Not classified | - | - | - | - | It was considered as the outside of Category based on rat LC50 (1 hour): >15000ppm (IUCLID, 2000) (4-hour equivalent >7500ppm), . |
1 | Acute toxicity (Inhalation: Vapours) | Not applicable | - | - | - | - | Gas (GHS definition) |
1 | Acute toxicity (Inhalation: Dusts and mists) | Not applicable | - | - | - | - | Gas (GHS definition) |
2 | Skin corrosion/irritation | Classification not possible | - | - | - | - | No data available |
3 | Serious eye damage/eye irritation | Classification not possible | - | - | - | - | Although it was indicated that the toxic effects to an eye was not known by HSDB (2005), there being no data which negates hazard clearly in Priority1. So it cannot classify. |
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 | Classification not possible | - | - | - | - | No data available. |
9 | Specific target organ toxicity - Repeated exposure | Classification not possible | - | - | - | - | No data available |
10 | Aspiration hazard | Not applicable | - | - | - | - | Gas (GHS definition) |
Hazard class | Classification | Symbol | Signal word | Hazard statement | Precautionary statement | Rationale for the classification | |
---|---|---|---|---|---|---|---|
11 | Hazardous to the aquatic environment (Acute) | Classification not possible | - | - | - | - | There is no data to classify. (Since it is a gaseous substance which does not dissolve into water easily due to ordinary temperatures, the test is not carried out.) |
11 | Hazardous to the aquatic environment (Long-term) | Classification not possible | - | - | - | - | No data available. (Since it is a gaseous substance which does not easily dissolve into water in the ordinary temperature, the test has not been carried out.) |
