PHYSICAL HAZARDS
Hazard class Classification Symbol Signal word Hazard statement Precautionary statement Rationale for the classification
1 Explosives Classification not possible - - - - Revision of the rational for classification of this substance was attempted. The substance contains an unsaturated C-C bond and its oxygen balance is -144, which is higher than the -200 threshold. However, since data on exothermic decomposition energy were not available, classification is not possible.
2 Flammable gases (including chemically unstable gases) Not applicable - - - - Solid (GHS definition)
3 Aerosols Not applicable - - - - Not aerosol products.
4 Oxidizing gases Not applicable - - - - Solid (GHS definition)
5 Gases under pressure Not applicable - - - - Solid (GHS definition)
6 Flammable liquids Not applicable - - - - Solid (GHS definition)
7 Flammable solid Classification not possible - - - - Although the substance is documented to be nonflammable (NAERG (J) (2004)), due to insufficient data, classification is not possible.
8 Self-reactive substances and mixtures Classification not possible - - - - No data available.
9 Pyrophoric liquids Not applicable - - - - Solid (GHS definition)
10 Pyrophoric solids Classification not possible - - - - No data available.
11 Self-heating substances and mixtures Classification not possible - - - - No data 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 - - - - Solid (GHS definition)
14 Oxidizing solids Not applicable - - - - Organic compounds containing oxygen and chlorine, with these elements chemically-bonded only to carbon or hydrogen.
15 Organic peroxides Not applicable - - - - Organic compounds containing no bivalent -O-O- structure in the molecule
16 Corrosive to metals Classification not possible - - - - Test methods applicable to solid substances are not available.

HEALTH HAZARDS

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.

Since the rat LD50 values are 1376-1429mg/kg (EHC 64 (1986)), the substance was classified into Category 4.
1 Acute toxicity (Dermal) Not classified - - - - Based on the rabbit LD50 >20000mg/kg (EHC 64 (1986)), the substance was classified into "Not classified". In rats, the LD50 of >1600mg/kg is documented (EHC 64 (1986)).
1 Acute toxicity (Inhalation: Gases) Not applicable - - - - Solid (GHS definition)
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 Category 1 Warning H317: May cause an allergic skin reaction P302+P352: IF ON SKIN: Wash with plenty of soap and water.
P333+P313: If skin irritation or rash occurs: Get medical advice/attention.
P261: Avoid breathing dust/fume/gas/mist/vapours/spray.
P272: Contaminated work clothing should not be allowed out of the workplace.
P280: Wear protective gloves/protective clothing/eye protection/face protection.
P321: Specific treatment (see ... on this label).
P363: Wash contaminated clothing before reuse.
P501: Dispose of contents/container to ...
Since studies using guinea pigs (maximization tests) concluded that the substance is a potent sensitizer (HSDB (2006)) and its EU classification is R43, the substance was classified into Category 1.
5 Germ cell mutagenicity Classification not possible - - - - Insufficient data available.
6 Carcinogenicity Classification not possible - - - - Insufficient data available.
7 Reproductive toxicity Classification not possible - - - - No data available.
8 Specific target organ toxicity - Single exposure Classification not possible - - - - Insufficient data available.
9 Specific target organ toxicity - Repeated exposure Classification not possible - - - - In 2-year oral route exposure studies, no effects of the substance were observed in rats administered at 150mg/kg in their diet and in dogs administered at 5mg/kg in their diet (HSDB (2006)). On the other hand, in oral route exposure studies in which guinea pigs and rabbits were administered with doses 1/10 of their LD50 values for 4-6 months, fatty dystrophy of the liver and kidneys, and hemosiderosis of the spleen were observed (HSDB (2006)). However, since these studies did not provide details including exact doses used, classification is not possible.
10 Aspiration hazard Classification not possible - - - - No data available.

ENVIRONMENTAL HAZARDS

11 Hazardous to the aquatic environment (Acute) Category 1 Warning H400: Very toxic to aquatic life P273: Avoid release to the environment.
P391: Collect spillage.
P501: Dispose of contents/container to ...
Since its 96-hour LC50 = 0.6mg/L for fish (rainbow trout) (HSDB 2006), the substance was classified into Category 1.
11 Hazardous to the aquatic environment (Long-term) Category 1 Warning H410: Very toxic to aquatic life with long lasting effects P273: Avoid release to the environment.
P391: Collect spillage.
P501: Dispose of contents/container to ...
Since its classification for acute toxicity is Category 1 and it is estimated not to be rapidly degradable (SRC: BioWin V4.10), the substance was classified into Category 1.
