The Japan Society for Occupational Health (JSOH) classified chromium compounds in occupational sensitizers to the airway Group 2. Although this substance is not specified in this classification, there is a description in OEL Documentations (Japan Society For Occupational Health (JSOH), 1989) that hexavalent chromium compounds are more toxic than divalent and trivalent compounds. In addition, there is a description that chromium compounds caused asthma (ATSDR (2012), EU-RAR (2005)). From the above, it was classified in Category 1.
4 Skin sensitization Category 1

P333+P313
P362+P364
P261
P272

Chromium compounds including this substance were classified in occupational skin sensitizers Group 1 by Japan Society For Occupational Health (JSOH) (Recommendation of Occupational Exposure Limits (Japan Society For Occupational Health (JSOH), 2014)). Although this substance is not specified in this classification, there is a description that hexavalent chromium compounds are more toxic than divalent or trivalent compounds in the OEL Documentations (Japan Society For Occupational Health (JSOH), 1989). In addition, there were many reports of contact dermatitis in workers who handled this substance (DFGOT vol. 15 (2001)). Moreover, although it is not information limited to this substance, there is a description that hexavalent chromium compounds were sensitizing to the skin (EU-RAR (2005), ATSDR (2012), PATTY (6th, 2012)). From the above, it was classified in Category 1.
5 Germ cell mutagenicity Category 2

P201
P202
P280
P405
P501
There are no in vivo data. As for in vitro, it was positive in bacterial reverse mutation tests, a gene mutation test, a chromosomal aberration test and a sister chromatid exchange test with cultured mammalian cells (IARC 49 (1990)). This substance is water-insoluble and in vivo mutagenicity information on water-insoluble Cr (VI) compounds was not obtained. This substance is a water-insoluble hexavalent chromium compound and it was classified in Category 2 according to the classification of other water-insoluble hexavalent chromium compounds.
The previous classification was changed.
6 Carcinogenicity Category 1A

Since it was classified in Group 1 (as chromium (VI)) by IARC (IARC (1990)), as A1 (as chromium (VI) compound) by ACGIH (ACGIH (7th, 2001)), as K (as hexavalent chromium compound) by NTP (NTP RoC (2014)) and in Group 1 (as chromium compound (hexavalent)) by Japan Society For Occupational Health (JSOH) (Japan Society For Occupational Health (JSOH), 1989), it was classified in Category 1A. In addition, this substance is classified as "Carc. Cat. 2; R45" in EU DSD classification, and as "Carc. 1B H350" in EU CLP classification.
7 Reproductive toxicity Category 2


Warning
H361 P308+P313
P201
P202
P280
P405
P501
There are no data on this substance.
As for reproductive toxicity of chromium (VI), potassium dichromate (CAS: 7778-50-9) and potassium chromate (CAS: 7789-00-6), water-soluble substances, were classified in Category 1B. Because this substance is insoluble in water, it was hard to say that it caused obvious reproductive effects on experimental animals. Therefore, it was classified in Category 2.
Besides, chromium and its compounds were classified in reproductive toxicants Group 3 (provisional) (correspond to Category 2) in Recommendation of Occupational Exposure Limits (2014) by Japan Society For Occupational Health (JSOH). However, because the classification of Recommendation of Occupational Exposure Limits was in a provisional period, it was not adopted.
8 Specific target organ toxicity - Single exposure Category 1 (central nervous system, respiratory organs, cardiovascular system, haemal system, liver, kidney)


Danger
H370 P308+P311
P260
P264
P270
P321
P405
P501
There are no data on this substance.
There are reports that respiratory tract irritation, respiratory tract inflammation, nose and chest pain, cough, dyspnea, cyanosis and kidney damage were observed by human inhalation exposure to hexavalent chromium compounds, that vomiting, diarrhea, gastrointestinal tract bleeding, liver necrosis, and renal tubular necrosis in the kidney were observed by human oral exposure, and that severe respiratory, cardiovascular, gastrointestinal, hematological, hepatic, renal, and neurological effects were reported by an accidental or intentional human ingestion at high-doses (ACGIH (7th, 2001), CICAD 78 (2013), EHC 61 (1988), EU-RAR (2005), ATSDR (2012)).

This substance is a hexavalent chromium compound, and it was considered possible to use the toxicity findings of hexavalent chromium compounds for classification of this substance. The findings on the gastrointestinal tract were not adopted because of local irritation.
From the above, it was classified in Category 1 (central nervous system, respiratory organs, cardiovascular system, hemal system, liver, kidney).
The previous classification was changed.
9 Specific target organ toxicity - Repeated exposure Category 1 (respiratory organs)


Danger
H372 P260
P264
P270
P314
P501
In epidemiological studies in workers occupationally exposed (co-exposure with lead chromate at multiple plants) to this substance at chromium pigment manufacturing plants which were conducted in Norway, UK, USA and Germany, etc., although an increase in the incidence of pulmonary cancer is described in all reports, there was no description of non-neoplastic effects by chronic exposure (ACGIH (7th, 2001)). In addition, there were no reports of clear effects by repeated exposure to this substance in either humans or experimental animals. However, based on multiple reports that the incidence of pulmonary cancer was increased by exposure to this substance alone or co-exposure with lead chromate, "the lung" was considered a target organ. Additionally, in the hazard assessment of a series of hexavalent chromium compounds including this substance, irritation of the respiratory tract and eyes were observed in humans who were exposed occupationally to hexavalent chromium compounds, as a result, it may cause ulcer/perforations in the nasal septum (CICAD 78 (2013)). Based on the above descriptions, this substance was classified in Category 1 (respiratory organs) just like other hexavalent chromium compounds.
