|---|---|---|---|---|---|---|---|
| 1 | Acute toxicity （Oral） | Category 4 |
|
Warning | H302: Harmful if swallowed |
P301+P312: IF SWALLOWED: Call a POISON CENTER or doctor/physician if you feel unwell. P264: Wash ... thoroughly after handling. P270: Do not eat, drink or smoke when using this product. P330: Rinse mouth. P501: Dispose of contents/container to ... |
Based on the rat LD50 (oral route) value of 1,265mg/kg (RTECS (2006)). |
| 1 | Acute toxicity （Dermal） | Classification not possible | - | - | - | - | No data available |
| 1 | Acute toxicity （Inhalation: Gases） | Not applicable | - | - | - | - | Due to the fact that the substance is "solid" according to the GHS definition and inhalation of its gas is not expected. |
| 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 | 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 ... |
Copper is classified into "Skin Sensitizing Substance" by the Japanese Society of Occupational Allergy, and "Skin Sensitizing Substance: Group 2" by the Japan Society for Occupational Health. (Note that the category refers to the substance concerned and its compounds, but does not identify all substances causing respiratory/skin sensitization.) These classifications apply to the present substance. Copper cyanide is thus classified into Category 1, though no data are available on animal and/or epidemiological studies for sensitization. |
| 5 | Germ cell mutagenicity | Classification not possible | - | - | - | - | No data available As for the health hazards, refer to "ID850, Copper, CAS: 7440-50-8." |
| 6 | Carcinogenicity | Classification not possible | - | - | - | - | No data available As for the health hazards, refer to "ID850, Copper, CAS: 7440-50-8." |
| 7 | Reproductive toxicity | Classification not possible | - | - | - | - | No data available As for the health hazards, refer to "ID850, Copper, CAS: 7440-50-8." |
| 8 | Specific target organ toxicity - Single exposure | Classification not possible | - | - | - | - | No data available |
| 9 | Specific target organ toxicity - Repeated exposure | Category 1 (central nervous system, respiratory system), Category 2 (kidney, spleen, liver, blood system) |
|
Danger Warning |
H372: Cause damage to organs through prolonged or repeated exposure (central nervous system, respiratory system) H373: May cause damage to organs through prolonged or repeated exposure (kidney, spleen, liver, blood system) |
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 ... |
Based on the human evidence including "headache, weakness, dysgeusia, dysosmia, dizziness, irritation of the pharynx, vomiting, dyspnea, lacrimation, salivation and anterior chest pain" (CICAD 61 (2004)), "the central nervous system is considered to be the most sensitive organ; respiratory depression is observed" (HSDB (2003)), and the evidence from animal studies including "tremor, spasm, laboured breathing" (CICAD 61 (2004)), "hemoglobin deposition in the cytoplasm of the proximal renal tubular epithelium, granular deposition in the spleen and liver, hyperplasia of the hematogenous tissues and hemolytic anemia" (IRIS (1987)). The effects on experimental animals were observed at dosing levels within the guidance value ranges for Category 2. |
