HEALTH HAZARDS
Hazard class Classification Symbol Signal word Hazard statement Precautionary statement Rationale for the classification
1 Acute toxicity (Oral) Category 5 - Warning H303: May be harmful if swallowed P312: Call a POISON CENTER or doctor/physician if you feel unwell. Based on the testing data of rat LD50 (oral route) of 3,608mg/kg (EHC 190 (1997)).
1 Acute toxicity (Dermal) Not classified - - - - Based on the testing data of rabbit LD50 (dermal route) of 14,100mg/kg (CERI Hazard Data 96-30 (i) (1997)).
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) Not classified - - - - Based on the LC50 value (4 hours) of 23.36mg/L (5,303ppm), calculated from the testing data of rat LC50 (6-hour inhalation) of 4,330ppm (EHC 190 (1997)), was lower than 90% of the saturated vapour concentration (7,900ppm) under a saturated vapour pressure of 0.80kPa (20degC), the substance was considered as "vapour containing substantially no mist" and was classified based on standard values expressed in ppm.
1 Acute toxicity (Inhalation: Dusts and mists) Classification not possible - - - - No data available
2 Skin corrosion/irritation Category 2 Warning H315: Causes skin irritation P302+P352: IF ON SKIN: Wash with plenty of soap and water.
P332+P313: If skin irritation occurs: Get medical advice/attention.
P264: Wash ... thoroughly after handling.
P280: Wear protective gloves/protective clothing/eye protection/face protection.
P321: Specific treatment (see ... on this label).
P362: Take off contaminated clothing and wash before reuse.
Based on the description in CERI Hazard Data 96-30 (i) (1997): Xylene mixtures (Cas 1330-20-7) cause moderate skin irritation, and the acute effects of o-xylene on human health are considered essentially equivalent to those of xylene mixtures. The substance is considered "moderately irritating" to the skin.
3 Serious eye damage/eye irritation Category 2A Warning H319: Causes serious eye irritation P305+P351+P338: IF IN EYES: Rinse cautiously with water for several minutes. Remove contact lenses, if present and easy to do. Continue rinsing.

P280: Wear protective gloves/protective clothing/eye protection/face protection.
Based on the description in CERI Hazard Data 96-30 (i) (1997): Xylene mixtures (Cas 1330-20-7) cause moderate eye irritation, and the acute effects of o-xylene on human health are considered essentially equivalent to those of xylene mixtures. The substance is considered "moderately irritating" to the eyes.
4 Respiratory sensitization Classification not possible - - - - No data available
4 Skin sensitization Classification not possible - - - - No data available

Based on the evidence from animal studies including "hypotension, lethargy, excitement of the central nervous system (at low concentrations), depression of the central nervous system (at high concentrations)" (EHC 190 (1997)). Narcotic influence is observed, with the biphasic effect on the central nervous system also included in narcotic influence.
9 Specific target organ toxicity - Repeated exposure Classification not possible - - - - Data exclusively on o-xylene are limited, while the dosages of all tests exceed the guidance value.
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 ...
Based on the description in ICSC (J) (2002): "May cause aspiration and chemical pneumonia if swallowed." Based on the fact that o-xylene is a hydrocarbon and has a dynamic viscosity of 0.86mm2/s (25degC) (CERI calculated value).

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 ...
It was classified into Category 1 from 72 hours ErC50=0.8mg/L of the algae (Selenastrum) (MOE Eco-Toxicity Tests of Chemicals (1996) and others.).
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 ...
Although acute toxicity is Category 1 and bio-accumulation is low (log Kow=3.12 (PHYSPROP Database, 2005)), since rapidly degrading was unknown, it was classiied into Category 1.
