4 | Respiratory sensitization | Category 1 | Danger | H334: May cause allergy or asthma symptoms or breathing difficulties if inhaled |
P304+P341: IF INHALED: If breathing is difficult, remove victim to fresh air and keep at rest in a position comfortable for breathing. P342+P311: If experiencing respiratory symptoms: Call a POISON CENTER or doctor/physician. P261: Avoid breathing dust/fume/gas/mist/vapours/spray. P285: In case of inadequate ventilation wear respiratory protection. P501: Dispose of contents/container to ... |
Chromium is classified into "Respiratory Sensitizing Substance" by the ad hoc committee of the Japanese Society of Occupational Allergy, and "Respiratory Sensitizing Substance: Group 2"* by the Japan Society for Occupational Health. These classifications, though not specifying potassium dichromate, seem to include chromium compounds. Potassium dichromate, which is a chromium compound, should thus cause respiratory sensitization. * There is a provision to the effect that "the category refers to the substance concerned and its compounds, but does not identify all substances causing respiratory/skin sensitization. | |
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 ... |
Based on the description of human health effects of occupational exposure provided by DFGOT vol.15 (2001): "contact dermatitis (skin sensitization: positive)" have been observed in workers who have handled zinc chromate, suggesting that the substance may cause skin sensitization. Chromium is classified into "Skin Sensitizing Substance" by the ad hoc committee of the Japanese Society of Occupational Allergy, and "Skin Sensitizing Substance: Group 1"* by the Japan Society for Occupational Health. These classifications, though not specifying potassium dichromate, seem to include chromium compounds. Potassium dichromate, which is a chromium compound, should thus cause skin sensitization. * There is a provision to the effect that "the category refers to the substance concerned and its compounds, but does not identify all substances causing respiratory/skin sensitization. | |
5 | Germ cell mutagenicity | Classification not possible | - | - | - | - | Based on the absence of data on in vivo mutagenicity/genotoxicity tests, and the absence of strong positive data on mutagenicity tests in vitro, described in IARC 49 (1990). As for the germ cell mutagenicity of chromium (VI), refer to potassium dichromate (CAS: 7778-50-9). |
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 ... |
Due to the fact that the substance is classified as Category K (as Chromium hexavalent (VI) compounds) by NTP (2005), A1 by ACGIH (2001), Group 1 (as Chromium (VI)) by IARC (1990), Category 1 (as Chromium hexavalent (VI) compounds) by the Japan Society for Occupational Health. | |
7 | Reproductive toxicity | Classification not possible | - | - | - | - | No data available As for the reproductive toxicity of chromium (VI), refer to potassium dichromate (CAS: 7778-50-9). |
8 | Specific target organ toxicity - Single exposure | Classification not possible | - | - | - | - | No data available The acute toxicity of hexavalent chromium compounds manifests as "cough, yellow-green phlegm, dyspnea, pulmonary congestion, vomiting (yellow-green mucus), gastralgia, diarrhea, nausea, vomiting, hepatic damage, renal damage" (CERI Hazard Data 97-18 (1998)). Refer to the GHS classification result of potassium dichromate (ID 0262, CAS 7778-50-09). |
9 | Specific target organ toxicity - Repeated exposure | Classification not possible | - | - | - | - | No data available The chronic toxicity of hexavalent chromium compounds manifests as "nasal mucosa, inflammation and ulcers in the pharynx and larynx, nasal septum perforation" (CERI Hazard Data 97-18 (1998)). Refer to the GHS classification result of potassium dichromate (ID 0262, CAS 7778-50-09). |
10 | Aspiration hazard | Classification not possible | - | - | - | - | No data available |
Hazard class | Classification | Symbol | Signal word | Hazard statement | Precautionary statement | Rationale for the classification | |
