HEALTH HAZARDS
Hazard class Classification Symbol Signal word Hazard statement Precautionary statement Rationale for the classification
1 Acute toxicity （Oral） Not classified - - - - Since its LD50 = 5410 mg/kg for rats (IUCLID (2000)), the substance was classified into "Not classified".
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 Not classified - - - - In a test using rabbits (according to OECD guideline 404), the substance was ranked on the irritation score at 0.6 (full score: 8) and as not irritating (IUCLID (2000)). Thus, it was classified into "Not classified".
3 Serious eye damage/eye irritation Category 1 Danger H318: Causes serious eye damage 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.
P310: Immediately call a POISON CENTER or doctor/physician. 		In a test using only a rabbit (according to OECD guideline 404), the test was stopped after one hour due to possible risk of irreversible effects by very strong irritation, and the substance is rated Xi; R41 in EU classification (EU-Annex I (accessed July 2008)). Thus, the substance was classified into Category 1. As relevant information, the pH value of its water solution (10 g/L) is so low as 2.1 (IUCLID (2000)).
4 Respiratory sensitization Classification not possible - - - - It is described that the substance has the potential to cause hypersensitivity effects including asthma (IUCLID (2000)). However, since the document is included in List 2, and there are no clear conclusions, the substance was classified into "Classification not possible".
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 ... 		In a skin sensitization test using guinea pigs (guinea pig maximization test: OECD guidelines 406), the positive reaction was found in 85% (17 of 20 subjects) of treated animals and the substance was concluded to be sensitizing (IUCLID (2000)). Based on this result, the substance was classified into Category 1.
5 Germ cell mutagenicity Classification not possible - - - - Insufficient data available. As relevant information, negative results have been reported from an in vitro test, Ames test (IUCLID (2000)).
6 Carcinogenicity Classification not possible - - - - No data available.
7 Reproductive toxicity Classification not possible - - - - No data available.
8 Specific target organ toxicity - Single exposure Category 3 （Respiratory tract irritation） Warning H335: May cause respiratory irritation (respiratory tract irritation) 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.
P405: Store locked up.
P501: Dispose of contents/container to ... 		Since acute symptoms, such as cough, sore throat, and wheezing, are described (HSDB (2007)), the substance was classified into Category 3 (respiratory tract irritation).
9 Specific target organ toxicity - Repeated exposure Classification not possible - - - - No data available.
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） Category 3 - - H402: Harmful to aquatic life P273: Avoid release to the environment.
P501: Dispose of contents/container to ... 		Since its 72h-EC50 = 65.7 mg/L for algae (Scenedesmus subspicatus) (IUCLID (2000)), the substance was classified into Category 3.
11 Hazardous to the aquatic environment （Long-term） Not classified - - - - Its preexisting classification for acute toxicity is Category 3. However, since its long-term toxicity datum; 72h-EC10 = 45.4 mg/L for algae (Scenedesmus subspicatus) (IUCLID (2000)), the substance was classified into "Not classified".
