1 Acute toxicity （Inhalation: Vapours） Classification not possible - - - - No data available.
1 Acute toxicity （Inhalation: Dusts and mists） Classification not possible - - - - No data available.

P363: Wash contaminated clothing before reuse.
P405: Store locked up.
P501: Dispose of contents/container to ... 		Two human cases of severe and bullous contact dermatitis have been reported (HSDB (2003)), and it is rated R35 in EU classification (EU Annex I (assessed on July, 2008)) and its pH = 1.4 (20degC, 50 g/L) (GESTIS (accessed July 2008)). Thus, the substance was classified into Category 1.
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. 		It has been documented to be a high irritant to human eyes and mucous membrane (HSDB (2003)), and rated R35 in EU classification (EU Annex I (accessed July 2008)) and its pH = 1.4 (20degC, 50 g/L) (GESTIS (accessed July 2008)). Thus, the substance was classified into Category 1. As relevant information, it is also classified as a corrosive agent to skin.
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 - - - - The only available datum is a weakly positive result from an Ames test (NTP DB (accessed July 2008)), and no other data are known.
6 Carcinogenicity Classification not possible - - - - The only available report is that subcutaneous administration to rats for 596 days produced a case of fibroma, a case of fibrosarcoma, and a case of plasma cell sarcoma (HSDB (2003)). No other data are known, thus, the substance cannot be classified.
7 Reproductive toxicity Classification not possible - - - - Non-oral administration to mice has been reported to cause defective ribs and vertebras and cleft palate (Birth Defects (3rd, 2000)). However, this study was performed relatively many years ago (1959, 1973), and does not provide information on such factors as the administration route and doses. Thus the substance cannot be classified due to lack of data.
8 Specific target organ toxicity - Single exposure Category 2 (eye) Warning H371: May cause damage to organs (eye) 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 ... 		Human exposure studies showed that the substance is toxic to essentially all parts of the eye, the cornea, iris, lens, ciliary body, and retina, when either applied directly or administered systemically (HSDB (2003)). In addition, its intravenous injection in rabbits, cats, and rats were found to induce cataracts, as well as to affect each part of the eye, such as lens, iris, and retina (HSDB (2003)). Since adverse effects on the human eyes after whole body exposure is indicated in the document of List 2, the substance was classified into Category 2 (eye).
9 Specific target organ toxicity - Repeated exposure Category 2 (systemic toxicity) Warning H373: May cause damage to organs through prolonged or repeated exposure (systemic toxicity) 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 ... 		The substance is documented to be highly capable of causing death or permanent injury due to exposures of normal use to humans (HSDB (2003)), and is reported that exposure orally to rats in their diet, 50 - 70 mg/kg/day has been found to be fatal in 10 - 40 days (HSDB (2003)). These human and rat data included in List 2 provide findings of death only, and do not provide findings on target organs. Thus, the substance was classified into Category 2 (systemic toxicity).
10 Aspiration hazard Classification not possible - - - - No data available.
