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 : 3750mg/kg (RTECS, 2005, IUCLID, 2000), 3540mg/kg (RTECS, 2005) and 3015mg/kg (IUCLID, 2000). The calculated value was 3229mg/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） 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. 		It was set as Category 2 from description that the skin is stimulated (ICSC (J) (2001), HSFS (2004), SITTIG (4th, 2002)).
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. 		It was set as Category 2A-2B from description that the eye is stimulated (ICSC (J) (2001), HSFS (2004), and SITTIG (4th, 2002)). Since there was no data about reparable, detailed categorization was not made.
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 Category 2 Warning H361: Suspected of damaging fertility or the unborn child P308+P313: IF exposed or concerned: Get medical advice/attention.
P201: Obtain special instructions before use.
P202: Do not handle until all safety precautions have been read and understood.
P281: Use personal protective equipment as required.
P405: Store locked up.
P501: Dispose of contents/container to ... 		Although there is no description on general toxicity in parent animals, based on the descriptions that increase in miscarriage and fetal death were observed in water drinking administration tests using guinea pigs (RTECS (2005), IUCLID (2000), HSDB (2005)) and that malformation was observed in baby animals in two-generation reproduction studies by mixed feeds administering using rats (IUCLID (2000), HSDB (2005)). So it was set as Category 2.
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 the oral administrations test in rats, and the description in ICSC (J) (2001), HSFS (2004), and SITTIG (4th, 2002) that methemoglobin may be generated, blood is considered as target organ and considered as Category 2. Moreover, from description in ICSC (J) (2001), HSFS (2004), 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 Category 2 (blood) Warning H373: May cause damage to organs through prolonged or repeated exposure (blood) P260: Do not breathe dust/fume/gas/mist/vapours/spray.
P314: Get medical advice/attention if you feel unwell.
P501: Dispose of contents/container to ... 		Since there was description that the symptoms of methemoglobinemia were observed in oral administration for 12 days in humans (HSDB (2005)), blood was considered to be target organ and classified into Category 2.
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 considered as the outside of Category from 48-hour TLm=490mg/L of Crustacea (Daphnia magna ) (IUCLID, 2000).
11 Hazardous to the aquatic environment （Long-term） Not classified - - - - Since not water-insoluble (water solubility=1g/2.8mL(PHYSPROP Database, 2005)) and acute toxicity is low.
