---|---|---|---|---|---|---|---|
1 | Acute toxicity (Oral) | Category 3 | Danger | H301: Toxic if swallowed |
P301+P310: IF SWALLOWED: Immediately call a POISON CENTER or doctor/physician. P264: Wash ... thoroughly after handling. P270: Do not eat, drink or smoke when using this product. P321: Specific treatment (see ... on this label). P330: Rinse mouth. P405: Store locked up. P501: Dispose of contents/container to ... |
There is no information about this substance. But we calculated the LD50 value of this substance using the molecular weight (Uranyl acetate:388, Uranyl acetate (dihydrate): 424), and it was classified as Category 3. The LD50 of this substance is about 187mg/kg, which was converted from the LD50 value in rats for the dihydrate of uranyl acetate: 204mg/kg (RTECS (1998)). [Note] We made the health hazard-related classification by using information about uranyl acetate (dihydrate) (ID1130, CAS#6159-44-0), because there is little information about this substance. | |
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. |
Since there was description that human skin is stimulated (HSDB (2002), HSFS (2000)), it was set as Category 2. | |
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. |
Due to the description that it irritates to human eye (HSDB(2002), HSFS(2000)), it was classified into Category 2A-2B. In addition, it is difficult to subdivide the Category of this data. | |
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 | 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 ... |
In administration in pregnant perinatal mice test, falling of average number of child, survival rates, childcare rate and pregnancy rate was observed (the toxicity to parent animals is unknown) and in tetis toxicity study and a mating trials with the non-taken female, the effects of father animal tetis was acknowledged only the highest concentrations. However, the thing for which the significant decline in a pregnancy rate was acknowledged in all 4 dose although there was no dose-dependent (toxicity to a father animal was only acknowledged by highest dosesignificant as weight decrease), (all PATTY(s) (5th, 2001)). And the dose which maternal toxicity (decrease of weight and intakes) is regarded as a teratogenicity study, increase of cleft palates and skeletal mutation was acknowledged (Catalog of teratogenic agents (2004), RTECS (1998)). So it was set as Category 2. | |
8 | Specific target organ toxicity - Single exposure | Category 1 (kidney), Category 3 (respiratory tract irritation) |
Danger Warning |
H370: Causes damage to organs (kidney) H335: May cause respiratory irritation (respiratory tract irritation) |
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 ... 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. |
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)). The substance was also classified as Category 3 (airway irritant) because its dust causes irritation to nose and throat (HSDB (2002)). | |
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 |
Hazard class | Classification | Symbol | Signal word | Hazard statement | Precautionary statement | Rationale for the classification | |
---|---|---|---|---|---|---|---|
11 | Hazardous to the aquatic environment (Acute) | Category 2 | - | - | H401: Toxic to aquatic life |
P273: Avoid release to the environment. P501: Dispose of contents/container to ... |
It was classified into Category 2 from 96-hour LC50=3.05mg/L of fishes (Zebrafish) (AQUIRE, 2003). |
11 | Hazardous to the aquatic environment (Long-term) | Category 2 | - | H411: Toxic to aquatic life with long lasting effects |
P273: Avoid release to the environment. P391: Collect spillage. P501: Dispose of contents/container to ... |
Classified into Category 2, since acute toxicity was Category 2 and it is a metallic compound, behavior in water and bioaccumulative potential are unknown. |
