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 ... |

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). |
