| Hazard class | Classification | Symbol | Signal word | Hazard statement | Precautionary statement | Rationale for the classification | |
|---|---|---|---|---|---|---|---|
| 1 | Explosives | Not applicable | - | - | - | - | Containing no chemical groups with explosive properties |
| 2 | Flammable gases （including chemically unstable gases） | Not applicable | - | - | - | - | Classified as "liquid" according to GHS definition |
| 3 | Aerosols | Not applicable | - | - | - | - | Not aerosol products |
| 4 | Oxidizing gases | Not applicable | - | - | - | - | Classified as "liquid" according to GHS definition |
| 5 | Gases under pressure | Not applicable | - | - | - | - | Classified as "liquid" according to GHS definition |
| 6 | Flammable liquids | Classification not possible | - | - | - | - | No data available. The isomer mixtures including p- and m- (mixing ratio unknown) have the boiling point of 195degC and the flash point of 76degC (open cup flash test) (ICSC (1999)), whereas the boiling point of o-divinylbenzene is 178.5degC (HSDB (2006)). According to some studies, "a good linear relationship is found between the flash points and the boiling points of the homologues, which indicates that the substance with a low boiling point generally has a low flash point" (Safety of Hazardous Substances, 2004). Based on this, the flash point of o-divinylbenzene is considered to be lower than 76degC, which can be included in "Categories 4, 3 or 2." |
| 7 | Flammable solids | Not applicable | - | - | - | - | Classified as "liquid" according to GHS definition |
| 8 | Self-reactive substances and mixtures | Classification not possible | - | - | - | - | Classification not possible due to lack of data, though containing unsaturated bonds (olefin) |
| 9 | Pyrophoric liquids | Classification not possible | - | - | - | - | No data available. The isomer mixtures including p- and m- (mixing ratio unknown) have the flash point of 500degC (ICSC (1999)) and are considered non-pyrophoric when in contact with air at ordinary temperatures. o-divinylbenzene per se is regarded non-pyrophoric when in contact with air at ordinary temperatures, and therefore "Not classified." |
| 10 | Pyrophoric solids | Not applicable | - | - | - | - | Classified as "liquid" according to 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 | - | - | - | - | Containing no metals or metalloids (B, Si, P, Ge, As, Se, Sn, Sb, Te, Bi, Po, At) |
| 13 | Oxidizing liquids | Not applicable | - | - | - | - | Organic compounds containing no oxygen, fluorine or chlorine |
| 14 | Oxidizing solids | Not applicable | - | - | - | - | Classified as "liquid" according to GHS definition |
| 15 | Organic peroxides | Not applicable | - | - | - | - | Organic compounds containing no "-O-O-" structure |
| 16 | Corrosive to metals | Classification not possible | - | - | - | - | No data available |

|---|---|---|---|---|---|---|---|
| 1 | Acute toxicity （Oral） | Classification not possible | - | - | - | - | No data available |
| 1 | Acute toxicity （Dermal） | Classification not possible | - | - | - | - | No data available |
| 1 | Acute toxicity （Inhalation: Gases） | Not applicable | - | - | - | - | Due to the fact that the substance is "liquid" 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） | Classification not possible | - | - | - | - | No data available |
| 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 | - | - | - | - | 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 Refer to GHS classification of divinylbenzene isomer mixtures (ID_0231, CAS 1321-74-0). |
| 9 | Specific target organ toxicity - Repeated exposure | Classification not possible | - | - | - | - | No data available Refer to GHS classification of divinylbenzene isomer mixtures (ID_0231, CAS 1321-74-0). |
| 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） | Classification not possible | - | - | - | - | No data available |
