PHYSICAL HAZARDS
| Hazard class | Classification | Symbol | Signal word | Hazard statement | Precautionary statement | Rationale for the classification | |
|---|---|---|---|---|---|---|---|
| 1 | Explosives | Not applicable | - | - | - | - | There are no chemical groups associated with explosive properties present in the molecule. |
| 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 | Category 4 | - | Warning | H227: Combustible liquid |
P370+P378: In case of fire: Use ... for extinction. P403+P235: Store in a well-ventilated place. Keep cool. P210: Keep away from heat/sparks/open flames/hot surfaces. - No smoking. P280: Wear protective gloves/protective clothing/eye protection/face protection. P501: Dispose of contents/container to ... |
Since its flash point reported 74 degC (closed-cup) (Ullmanns (E) (6th, 2003)) is > 60 degC and <= 93 degC, the substance corresponds to Category 4. |
| 7 | Flammable solids | Not applicable | - | - | - | - | Liquid (GHS definition) |
| 8 | Self-reactive substances and mixtures | Not applicable | - | - | - | - | There are no chemical groups present in the molecule associated with explosive or self-reactive properties. |
| 9 | Pyrophoric liquids | Not classified | - | - | - | - | Since its autoignition temperature is 200 degC (Ullmanns (E) (6th, 2003)), it is considered that the substance does not ignite at room temperature. |
| 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 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 | - | - | - | - | Liquid (GHS definition) |
| 15 | Organic peroxides | Not applicable | - | - | - | - | Organic compounds containing no bivalent -O-O- structure. |
| 16 | Corrosive to metals | Classification not possible | - | - | - | - | No data available. It is reported that steel is durable as a container (Hommel (1996)). |
| Hazard class | Classification | Symbol | Signal word | Hazard statement | Precautionary statement | Rationale for the classification | |
|---|---|---|---|---|---|---|---|
| 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 | - | - | - | - | Liquid (GHS definition) |
| 1 | Acute toxicity （Inhalation: Vapours） | Classification not possible | - | - | - | - | It was reported that in rats, exposure to this substance of 0.99 mg/L (142 ppm) for 8 hours (converted dose level as that of 4-hour: 200 ppm) caused no mortality (EHC 187 (1996)). Since the result did not provide the basis for the classification, the classification was not possible. The test concentration (142 ppm) was lower than 90% of the saturated vapor pressure concentration (161ppm), the criterion values of gas were adopted. |
| 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 | Not classified | - | - | - | - | In the rabbit test, the irritation scores were 0 for corneal opacity, 0 for iritis, 1.3 for conjunctival redness, and 0 for chemosis, respectively. Symptoms were all reversible in 3 days, and eye irritation index (MMAS) was 2/110 (ECETOC TR48 (1998)). Based on the information, the substance was classified as "Not classified". |
| 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 | Category 1 |
|
Danger | H304: May be fatal if swallowed and enters airways |
P301+P310: IF SWALLOWED: Immediately call a POISON CENTER or doctor/physician. P331: Do NOT induce vomiting. P405: Store locked up. P501: Dispose of contents/container to ... |
This substance was classified as Category 1 because it was hydrocarbon liquid having the coefficient of kinematic viscosity of 1.85 mm2/s calculated from the coefficient of viscosity of 1.383 mPa*s (25 degrees centigrade) (Lide, 90th (2009)) and the density of 0.748 g/cm3 (20 degree centigrade) (HODOC, 3rd (1994)). |
| 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. |
| 11 | Hazardous to the aquatic environment （Long-term） | Classification not possible | - | - | - | - | No data available. |
| 12 | Hazardous to the ozone layer | Classification not possible | - | - | - | - | This substance is not listed in Annexes to the Montreal Protocol. |
