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. We calculated based on the rat LD50 values : 2217mg/kg (RTECS, 2005, IUCLID, 2000), 2800mg/kg, 2462mg/kg, 2950mg/kg, 5600mg/kg and 4820mg/kg (IUCLID, 2000), and 4500mg/kg (HSDB, 2005)s. The calculated value was 2798 mg/kg, so the substance was classified as Category 5.
1 Acute toxicity （Dermal） Classification not possible - - - - No data available
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） Not classified - - - - Not classified because of "SPECIES: Rat; ENDPOINT: LC50(4hr.; VALUE: >88.8mg/L"(IUCLID, 2000)
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. 		There is description that skin irritation was not admitted by the test using the rabbit (IUCLID (2000)), it was set to category 2 since ICSC (J) (2001), HSDB (2005), HSFS (1998), and SITTIG (4th, 2002) had no report of specific cases but there is description that the skin of what is indicated and is not may be stimulated.
3 Serious eye damage/eye irritation Category 2A-2B 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.
P337+P313: If eye irritation persists: Get medical advice/attention.
P264: Wash ... thoroughly after handling.
P280: Wear protective gloves/protective clothing/eye protection/face protection. 		Although change of the eye which corresponds to criteria for diagnosis of irritation by the eye irritation tests using the rabbit indicated to ECETOC TR 48 (1992) is not admitted. But there is description that there is stimulativeness to the human eye in any of ICSC(J) (2001), HSDB (2005), HSFS (1998), and SITTIG (2002). So it was set as Category 2A-2B.
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 - - - - Classification not possible due to lack of data
6 Carcinogenicity Classification not possible - - - - No data available
7 Reproductive toxicity Classification not possible - - - - Classification not possible due to lack of data
8 Specific target organ toxicity - Single exposure Category 2 (blood), Category 3 (respiratory tract irritation) Warning H371: May cause damage to organs (blood)
H335: May cause respiratory irritation (respiratory tract irritation) 		P309+P311: IF exposed or if you feel unwell: Call a POISON CENTER or doctor/physician.
P260: Do not breathe dust/fume/gas/mist/vapours/spray.
P264: Wash ... thoroughly after handling.
P270: Do not eat, drink or smoke when using this product.
P405: Store locked up.
P501: Dispose of contents/container to ...
P304+P340: IF INHALED: Remove victim to fresh air and keep at rest in a position comfortable for breathing.
P403+P233: Store in a well-ventilated place. Keep container tightly closed.
P261: Avoid breathing dust/fume/gas/mist/vapours/spray.
P271: Use only outdoors or in a well-ventilated area.
P312: Call a POISON CENTER or doctor/physician if you feel unwell. 		From the description in RTECS (2005) that methemoglobinemia was observed in oral administration examination in rat, and the description in ICSC (J) (2001), HSDB (2005), HSFS (1998), and SITTIG (4th, 2002) that methemoglobin or abnormal hemoglobin may be generated, it was judged that blood was target organ, and it was considered as Category 2. Moreover, from the description in ICSC (J) (2001), HSDB (2005), HSFS (1998), and SITTIG (4th, 2002) that the airway is stimulated, it was judged that it has airway stimulativeness and was considered as Category 3.
9 Specific target organ toxicity - Repeated exposure Classification not possible - - - - Classification not possible due to lack of data
10 Aspiration hazard Classification not possible - - - - No data available

ENVIRONMENTAL HAZARDS
Hazard class Classification Symbol Signal word Hazard statement Precautionary statement Rationale for the classification
11 Hazardous to the aquatic environment （Acute） Not classified - - - - It carried out the outside of Category from 96-hour LC50=5657mg/L of fishes (Rainbow trout) (IUCLID, 2000).
11 Hazardous to the aquatic environment （Long-term） Not classified - - - - Since not water-insoluble (water solubility=118.3g/100cc(HSDB, 2004)) and acute toxicity is low.
