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 | Classification not possible | - | - | - | - | Insufficient data available. As relevant notes, two data of 90 degC (Gangolli (2nd, 1999)) and 117.8 degC (Sax (11th, 2004)) were obtained, which are in the range corresponding to Category 4 or "Not classified", but measurement methods for both values are unknown. |
| 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 500 degC (GESTIS (Access on Oct. 2010)), 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 | - | - | - | - | The substance is an organic compound containing chlorine and oxygen which are chemically bonded only to carbon or hydrogen. |
| 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. |
| Hazard class | Classification | Symbol | Signal word | Hazard statement | Precautionary statement | Rationale for the classification | |
|---|---|---|---|---|---|---|---|
| 1 | Acute toxicity （Oral） | Category 4 |
|
Warning | H302: Harmful if swallowed |
P301+P312: IF SWALLOWED: Call a POISON CENTER or doctor/physician if you feel unwell. P264: Wash ... thoroughly after handling. P270: Do not eat, drink or smoke when using this product. P330: Rinse mouth. P501: Dispose of contents/container to ... |
Based on the mouse LD50 value of 1207 mg/kg bw (RTECS (1997), original literature: Pharmazie, 31, 317 (1976)), the substance was classified as Category 4. |
| 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 | - | - | - | - | No data were available. As relevant information for 1-chloroacetophenone, the mouse LC50 value of 1.752 mg/L (= 277 ppm) for 15 minutes exposure was reported (RTECS (1997)). |
| 1 | Acute toxicity （Inhalation: Dusts and mists） | Classification not possible | - | - | - | - | No data available. |
| 2 | Skin corrosion/irritation | Classification not possible | - | - | - | - | No data were available. As relevant information, there was one case report of acute contact dermatitis caused by exposure to 2-chloroacetophenone tear gas. Within 3 days the contact dermatitis disappeared without medical treatment. However, at 7 days after exposure, desquamative pruritic eruption developed at the site of the original exposure without new contact with the substance (HSDB (2003)). |
| 3 | Serious eye damage/eye irritation | Classification not possible | - | - | - | - | No data were available. As relevant notes, it is reported that the substance is highly irritating to eyes and mucous membranes (HSDB (2003)). |
| 4 | Respiratory sensitization | Classification not possible | - | - | - | - | No data available. |
| 4 | Skin sensitization | Classification not possible | - | - | - | - | No data were available. As relevant notes, it was described that chloroacetophenone used as tear gas could evoke toxic and allergic contact dermatitis, and rarely caused exanthematous or anaphylactic reactions (HSDB (2003)). |
| 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 were available. As relevant information on 1-chloroactophenone, it was reported that histological alterations in the lungs, liver and kidneys were caused in mice exposed by inhalation at the concentration of 87.6 mg/m3 for 10 days (15 minutes/day). However, the details were unknown (RTECS (1997), original literature: Journal of Applied Toxicology, 14, 411 (1994)). |
| 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. |
| 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. |
