HEALTH HAZARDS
Hazard class Classification Symbol Signal word Hazard statement Precautionary statement Rationale for the classification
1 Acute toxicity （Oral） Classification not possible - - - - No data available
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 Classification not possible - - - - There is a publication that a thorium compounds stimulates the skin (SITTIG (4th, 2002)). But there is no this product data, and data is insufficient, it cannot be classified. In addition, also refer to oxalic acid (ID No.0595, CAS No.144-62-7).
3 Serious eye damage/eye irritation Classification not possible - - - - Although there is a statement that a thorium compounds stimulates an eye to SITTIG (4th, 2002), there is no this product data. So data is insufficient, it cannot classify. In addition, refer to oxalic acid (ID No.0595, CAS No.144-62-7).
4 Respiratory sensitization Classification not possible - - - - No data available
4 Skin sensitization Classification not possible - - - - No data available
5 Germ cell mutagenicity Category 2 Warning H341: Suspected of causing genetic defects 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 ... 		There was no this product data. But there is the description that thorium is a radioactive material, and chromosome aberration and gene mutations in humans were induced by internal contamination of thorium oxide (IARC 78, 2001;HSDB, 2003). Moreover, there is the description thorium or thorium compound suggest hereditary genetic damage affects (ICSC (J) 1990; SITTIG, 4th, 2002). So it is classified into Category 2
6 Carcinogenicity Category 1 Danger H350: May cause cancer 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 ... 		There is no this product data. But the thorium oxide which is the same thorium compound is categoried into Group 1 according to IARC 78 (2001), and is categoried into K according to NTP RoC (11th, 2005) (all are about Category 1). This product was also set to 1 in consideration of being a radioactive material.
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 this product data, ICSC (J) (1990) and SITTIG (4th, 2002) of Priority 2 document, describes that thorium or thorium compound as radioactive material that induce congenital anomaly is suggested (and PATTY (5th, 2001) also reports that incidence of congenital anomalies was high in the residents near the graveyard of a thorium content). So it was set as Category 2.
8 Specific target organ toxicity - Single exposure Category 2 (lung, bone marrow) Warning H371: May cause damage to organs (lung, bone marrow) 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 ... 		Although there is no data about this product , Since in ICSC (J) (1990), SITTIG (4th, 2002) of Priority 2 document has description that lungs and marrow (hematopoietic systems) are affected by short-term exposures of thorium or thorium compounds, and it was considered as Category 2 (pneumoconiosis,marrow).
9 Specific target organ toxicity - Repeated exposure Category 2 (lung, liver, kidney, reticuloendothelial system) Warning H373: May cause damage to organs through prolonged or repeated exposure (lung, liver, kidney, reticuloendothelial system) 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 ... 		Although there is no this product data, there is a statement that lung, liver, kidney, and reticuloendothelial system are affected in repeated exposure of thorium or thorium compound( ICSC(J)(1990), and SITTIG(4th, 2002) of Priority 2 document) (although it is not clear whether it is repeated exposure, there are similar descriptions also in PATTY (5th, 2001)), it was classified into Category 2 (lungs, liver, the kidney, reticuloendothelial system).
