PHYSICAL HAZARDS
Hazard class Classification Symbol Signal word Hazard statement Precautionary statement Rationale for the classification
1 Explosives Classification not possible - - - - Classification not possible due to lack of data and without UNRTDG Number, though the substance contains N-O bonds as chemical groups associated with explosive properties present and "A violent impact to the substance might cause an explosion with a spread of the shock wave. " (Merck, 13th, 2001)
2 Flammable gases （including chemically unstable gases） Not applicable - - - - Solid (GHS definition)
3 Aerosols Not applicable - - - - Not aerosol products
4 Oxidizing gases Not applicable - - - - Solid (GHS definition)
5 Gases under pressure Not applicable - - - - Solid (GHS definition)
6 Flammable liquids Not applicable - - - - Solid (GHS definition)
7 Flammable solids Not classified - - - - HSDB (2005) has the statement as "almost nonflammable" and it was classified as out of Category. (However, it is considered to be an oxidant and the contact with combustibles should be avoided.)
8 Self-reactive substances and mixtures Not classified - - - - Although the grouping relevant to explosive (N-O) was included, the grouping relevant to autoreactive was not included. And the information which indicates autoreactive was not found either, it was classified as the outside of Category.
9 Pyrophoric liquids Not applicable - - - - Solid (GHS definition)
10 Pyrophoric solids Not classified - - - - HSDB (2005) has a statement that it is "nonflammable" and it was defined as "out of Category". (However, it is considered to be an oxidized substance and contacting combustible materials should be avoided.)
11 Self-heating substances and mixtures Not classified - - - - Not classified because of non-combustible (HSDB, 2005)
12 Substances and mixtures which, in contact with water, emit flammable gases Not classified - - - - Stable to water (the water solubility is obtained)
13 Oxidizing liquids Not applicable - - - - Solid (GHS definition)
14 Oxidizing solids Classification not possible - - - - Since Sax (11th, 2004) describes that the anhydride of this product is a "powerful oxidizer and avoid contact with cellulose," the product is also considered as an oxidizing solid. But we cannot classify it because it does not have UNRTDG No. and is short of information which gives an indication of classification.
15 Organic peroxides Not applicable - - - - Inorganic compound
16 Corrosive to metals Classification not possible - - - - Test methods applicable to solid substances are not available. Its acidic solution is corrosive to metals (HSDB, 2005)

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 - - - - No data available
3 Serious eye damage/eye irritation Classification not possible - - - - No data available
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 ... 		Since the chromosomal abnormalities was acknowledged in the uranium compounds in peripheral lymphocyte of workers by which occupational exposure was carried out (PATTY (5th, 2001)), it was set as Category 2 according to classification guidelines.
6 Carcinogenicity Category 1A 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 ... 		As uranium and its soluble and insoluble compounds, it was categorized into A1(IARC78 (2001)) in ACGIH, and as radionuclide which depoited in the body, it was categorized into 1 in A1 (ACGIH (7th, 2001)). So it was classified into Category 1A.
7 Reproductive toxicity Classification not possible - - - - No data available
8 Specific target organ toxicity - Single exposure Category 1 (kidney) Danger H370: Causes damage to organs (kidney) P307+P311: IF exposed: 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.
P321: Specific treatment （see ... on this label）.
P405: Store locked up.
P501: Dispose of contents/container to ... 		The substance was classified as Category 1 (kidneys) because there is a report in Priority 1 of the effects on the kidneys, such as necrosis of the proximal convoluted tubules and collecting tubules, after exposure to the uranium compound in humans (ACGIH (7th, 2001)).
9 Specific target organ toxicity - Repeated exposure Category 1 (kidney) Danger H372: Cause damage to organs through prolonged or repeated exposure (kidney) 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.
P314: Get medical advice/attention if you feel unwell.
P501: Dispose of contents/container to ... 		Since there is description that the major target organ of the chronic toxicity in a uranium compound was the kidney (mainly proximal tubule) (in Priority 1,ACGIH (7th, 2001)), it was classified into Category 1 (kidney).
10 Aspiration hazard Classification not possible - - - - No data available
