Moreover, exposure to hexavalent chromium compounds may also induce asthma (Risk Assessment Report (Beverages) on hexavalent chromium (Food Safety Commission of Japan, 2018)). (2) Chromium compounds are known as sensitizers to the skin and respiratory organs. Also, when sensitization is established, a challenge occurs in that both trivalent and hexavalent chromium compounds can induce an allergic response (ACGIH (7th, 2018)). (3) Chromium released from chromium compounds was designated as occupational sensitizers to the airway Group 2 (OEL Documentations (Sensitizers classification) (Japan Society For Occupational Health (JSOH), 2010)).	FY2019	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))

5	Germ cell mutagenicity	Category 1B	Danger	H340	P308+P313 P201 P202 P280 P405 P501	[Rationale for the Classification] Based on (1) and (2), though there are no in vivo data on this substance, it was classified in Category 1B from positive results from in vitro tests and results on hexavalent chromium compounds. [Evidence Data] (1) As for in vivo, there are no test data on this substance. As for hexavalent chromium compounds, positive results were obtained in a gene mutation test, a chromosomal aberration test, a micronucleus test and a DNA damage test with mice and rats dosed intraperitoneally, a DNA damage test with mice administered by gavage was positive, and a micronucleus test with mice dosed by drinking water was mostly negative (Risk Assessment Report (Beverages) (Food Safety Commission of Japan, 2018)). (2) As for in vitro, a positive result in a bacterial reverse mutation test was reported (IARC 49 (1990), HSDB (Access on July 2019)). As for hexavalent chromium compounds, though bacterial reverse mutation tests were both positive and negative, positive results were obtained in a chromosomal aberration test, an unscheduled DNA synthesis test and a transformation test with cultured mammalian cells (Risk Assessment Report (Beverages) (Food Safety Commission of Japan, 2018)). [Reference Data, etc.] (3) As for classification results by domestic and international organizations, it was classified in Muta.1B in the EU CLP (EU CLP classification (Access on June 2019)). (4) It was reported that there are sufficient indications to conclude that the exposure of humans to this substance can lead to hereditary disorders (GESTIS (Access on July 2019)). (5) It was reported that hexavalent chromium compounds caused gene mutation with bacterium and chromosomal aberrations with mammalian cells, and that they were associated with an increased frequency of chromosomal aberrations in lymphocytes of workers engaged in the production of chromates (HSDB (Access on July 2019)).

6	Carcinogenicity	Category 1A	Danger	H350	P308+P313 P201 P202 P280 P405 P501	[Rationale for the Classification] Based on classification results by other organizations in (1), it was classified in Category 1A in accordance with the GHS Classification Guidance for the Japanese Government. [Evidence Data] (1) As for the classification results by domestic and international organizations, it was classified in Group 1 by IARC (IARC 100C (2012)), in A1 by ACGIH (ACGIH (7th, 2018)), in Carc.1B by EU (EU CLP classification (Access on July 2019)) as hexavalent chromium compounds.	FY2019	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
7	Reproductive toxicity	Category 2	Warning	H361	P308+P313 P201 P202 P280 P405 P501	[Rationale for the Classification] There is no information on this substance. However, based on (1), it was classified in Category 2. [Evidence Data] (1) The Japan Society For Occupational Health (JSOH) classified chromium and chromium compounds in reproductive toxicants Group 3 (corresponding to Category 2) (OEL Documentations (Japan Society For Occupational Health (JSOH), 2014)).	FY2019	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
8	Specific target organ toxicity - Single exposure	Category 1 (central nervous system, respiratory organs, cardiovascular system, blood system, liver, kidney)	Danger	H370	P308+P311 P260 P264 P270 P321 P405 P501	[Rationale for the Classification] There is no report of single exposure to this substance in humans and experimental animals. However, based on (1)-(3), it was classified in Category 1 (central nervous system, respiratory organs, cardiovascular system, blood system, liver, kidney). As for the gastrointestinal tract, it was not adopted as a target organ since the effect was considered to be that of local irritation. [Evidence Data] (1) This substance easily hydrolyses to chromic acid (CAS RN 7738-94-5) and hydrochloric acid (CAS RN 7647-01-0) on contact with water. At inhalation of the vapours, it may completely hydrolyse to chromic acid and hydrochloric acid in the respiratory tract, additionally it may also generate chlorine (CAS RN 7782-50-5) and chromium trichloride (CAS RN 10025-73-7, trivalent chromium compound) (GESTIS (Access on July 2019), ACGIH (7th, 2018)). Chromic acid, hydrochloric acid and chlorine were all reported to affect the respiratory organs in humans or experimental animals. (2) There is a description that contact of this substance with the skin, respiratory tract, and eyes will result in severe irritation and burns, and lung edema may occur with high exposures (ACGIH (7th, 2018)). Additionally, there is a description that after inhalation of this substance, severe irritation and corrosion of the respiratory tract must be expected and the hazard of laryngeal and lung edemas was considered (GESTIS (Access on July 2019)). (3) There is a description that effects on the gastrointestinal tract, kidney, central nervous system, blood system, liver and heart, similar to those of chromic acid, may occur in the case of accidental oral intake of this substance (GESTIS (Access on July 2019)). [Reference Data, etc.] (4) Chromic acid (H2CrO4) is an aqueous solution of chromic anhydride (CrO3, chromium trioxide, CAS RN 1333-82-0). Chromic anhydride was classified in Category 1 (central nervous system, respiratory organs, cardiovascular system, blood system, liver, kidney) in FY 2014 GHS classification.	FY2019	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
9	Specific target organ toxicity - Repeated exposure	Category 1 (respiratory organs)	Danger	H372	P260 P264 P270 P314 P501	[Rationale for the Classification] Based on (1) and (2), though this substance is highly reactive, and it is not clear whether its toxicity is similar to that of other hexavalent chromium compounds, it is considered that at least the effects of chromic acid, etc. generated by hydrolysis will occur. Based on information on chromic acid in (3) and (4), since it was considered that inhalation exposure in humans causes effects on the respiratory organs, it was classified in Category 1 (respiratory organs). [Evidence Data] (1) This substance easily hydrolyses to chromic acid and hydrochloric acid on contact with water. On inhalation of vapour, it may completely hydrolyse to chromic acid (CAS RN 7738-94-5) and hydrochloric acid (CAS RN 7647-01-0) in the respiratory tract, additionally it may also generate chlorine (CAS RN 7782-50-5) and chromium trichloride (CAS RN 10025-73-7, trivalent chromium compound) (GESTIS (Access on July 2019)). (2) Since the acid chloride is highly reactive and the extent of the formation of chromium (III) compounds cannot be estimated, metabolization, similar to that of less reactive hexavalent chromium compounds, may not occur (GESTIS (Access on July 2019)). (3) As for chromic acid, there is the information that nasal mucosal ulceration, septal perforation, etc. were observed in a study examining symptoms in respiratory organs, pulmonary function and the nasal mucosa in 43 workers exposed to chromic acid in a chrome plating plant (CICAD 78 (2013)). (4) As for chromic acid, there is a report that when rats were exposed by inhalation to chromic anhydride mist for 8 months, corrosive effects in the respiratory tract were observed at or above 3.5 mg/m3 (EU-RAR (2005)). Moreover, there is a report that when mice were intermittently exposed to chromic anhydride at a concentration of about 3.9 mg/m3 over a 12-month period, emphysema and nasal septum perforation were developed (CICAD 78 (2013)). Thus, findings supporting disorders of the respiratory organs in humans were obtained. [Reference Data, etc.] (5) Chromic anhydride (CAS RN 1333-82-0) was classified in Category 1 (respiratory organs) in FY 2014 GHS classification.
