P405: Store locked up.
P501: Dispose of contents/container to ... 		Based on the description in ATSDR (2000) of human health effects: "dermal necrosis and exfoliation were observed after application of a plaster containing potassium chromate," "ulceration occurs among the workers who come into contact with high concentrations of sodium chromate, potassium dichromate or potassium chromate," suggesting that potassium chromate may cause irreversible irritation of an unknown degree. Although classified as Category 1A-1C, the substance should be placed in Category 1A from the viewpoint of safety, if further subclassification is needed.

P280: Wear protective gloves/protective clothing/eye protection/face protection.
P310: Immediately call a POISON CENTER or doctor/physician. 		In accordance with the technical guideline, given the fact that the substance is classified into Category 1 of skin corrosion/irritation.
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 results of human patch tests (ATSDR (2000)) (skin sensitization: positive). 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.

P281: Use personal protective equipment as required.
P405: Store locked up.
P501: Dispose of contents/container to ... 		Based on the absence of data on multi-generation mutagenicity tests, germ cell mutagenicity tests in vivo and germ cell genotoxicity tests in vivo, positive data on somatic cell mutagenicity tests in vivo (micronucleus tests), described in IARC 49 (1999), ATSDR (2000), EHC 61 (1988).
6 Carcinogenicity Category 1A Danger H350: May cause cancer P308+P313: IF exposed or concerned: Get medical advice/attention.

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

11 Hazardous to the aquatic environment （Acute） Category 1 Warning H400: Very toxic to aquatic life P273: Avoid release to the environment.
P391: Collect spillage.
P501: Dispose of contents/container to ... 		It was classified into Category 1 from 48 hours EC50=19.2microg/L(Potassium Chromate Equivalent: 71.7microg/L) of the crustacea (Daphnia magna) (HSDB, 2004).
11 Hazardous to the aquatic environment （Long-term） Category 1 Warning H410: Very toxic to aquatic life with long lasting effects P273: Avoid release to the environment.
P391: Collect spillage.
P501: Dispose of contents/container to ... 		Since acute toxicity was Category 1 and it was a metallic compound, and since an underwater action and bio-accumulation were unknown, it was classified into Category 1.
