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 - - - - 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 - - - - Insufficient data available Based on the description in ACGIH (7th, 2001), ATSDR (2000), CERI Hazard Data 97-18 (1998), EHC 61 (1988) and EU-RAR No.53 (2005): Substances including barium chromate may cause chromium ulcers and skin ulcers (chromium holes) in humans.
3 Serious eye damage/eye irritation Classification not possible - - - - Insufficient data available Based on the description in EU-RAR No.53 (2005) of the effects on human health: Accidental splashing of highly water-soluble Cr(VI) compounds in solution into the eye has resulted in damage to the human eye; A number of case reports indicate corneal/conjunctival inflammation and severe symptoms such as corneal erosion and ulceration, with the intensity of the symptoms increasing at lower pH and higher temperatures; Accidental exposure causes corneal edema and opacity; Single and repeated exposure causes severe, persistent damage to the eye and skin associated with the formation of ulcers.
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 ...

5 Germ cell mutagenicity Classification not possible - - - - No data available As for the germ cell mutagenicity of chromium (IV), 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), 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 (IV), 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
