PHYSICAL HAZARDS
| Hazard class | Classification | Symbol | Signal word | Hazard statement | Precautionary statement | Rationale for the classification | |
|---|---|---|---|---|---|---|---|
| 1 | Explosives | Classification not possible | - | - | - | - | Classification not possible due to lack of data and without UNRTDG Number, though the substance contains unsaturated C-C bonds chemical groups with explosive properties present. |
| 2 | Flammable gases （including chemically unstable gases） | Not applicable | - | - | - | - | Liquid (GHS definition) |
| 3 | Aerosols | Not applicable | - | - | - | - | Not aerosol products |
| 4 | Oxidizing gases | Not applicable | - | - | - | - | Liquid (GHS definition) |
| 5 | Gases under pressure | Not applicable | - | - | - | - | Liquid (GHS definition) |
| 6 | Flammable liquids | Not classified | - | - | - | - | The statement that flash point was 160 degC was in All Data for Poisonous and Violent Substances Control Law MSDS controlled substance (Chemical Daily, 2001) (similar description was also found in research reagent MSDS), and it was considered as out of Category. |
| 7 | Flammable solids | Not applicable | - | - | - | - | Liquid (GHS definition) |
| 8 | Self-reactive substances and mixtures | Not classified | - | - | - | - | Although the grouping relevant to explosive (unsaturated C-C combination) was included, the grouping relevant to autoreactive was not included and it was used as pesticide. So it was thought that there was no autoreactive and it was classified as outside of Category. |
| 9 | Pyrophoric liquids | Not classified | - | - | - | - | Uses are agricultural chemicals, and even if it contacts the normal temperature air, it does not ignite spontaneously. |
| 10 | Pyrophoric solids | Not applicable | - | - | - | - | Liquid (GHS definition) |
| 11 | Self-heating substances and mixtures | Classification not possible | - | - | - | - | Test methods applicable to liquid substances are not available |
| 12 | Substances and mixtures which, in contact with water, emit flammable gases | Not applicable | - | - | - | - | The chemical structure of the substance does not contain metals or metaloids(B, Si, P, Ge, As, Se, Sn, Sb, Te, Bi, Po, At). |
| 13 | Oxidizing liquids | Not applicable | - | - | - | - | Organic compounds containing chlorine chemically bonded only to carbon (but not to other elements). |
| 14 | Oxidizing solids | Not applicable | - | - | - | - | Liquid (GHS definition) |
| 15 | Organic peroxides | Not applicable | - | - | - | - | Organic compounds containing no -0-0- structure |
| 16 | Corrosive to metals | Classification not possible | - | - | - | - | No data available |
| Hazard class | Classification | Symbol | Signal word | Hazard statement | Precautionary statement | Rationale for the classification | |
|---|---|---|---|---|---|---|---|
| 1 | Acute toxicity （Oral） | Category 3 |
