HEALTH HAZARDS

Hazard class		Classification	Pictogram Signal word	Hazard statement (code)	Precautionary statement (code)	Rationale for the classification	Classification year (FY)	GHS Classification Guidance for the Japanese Government
1	Acute toxicity (Oral)	Not classified	- -	-	-	Based on a report (IUCLID (2000)) of an LD50 value for rats of >5,000 mg/kg (OECD TG 401), it was classified as "Not classified." Since a new information source (IUCLID (2000)) was added, the category was revised.	FY2014	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0))
1	Acute toxicity (Dermal)	Classification not possible	- -	-	-	Classification not possible due to lack of data.	FY2014	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0))
1	Acute toxicity (Inhalation: Gases)	Not classified (Not applicable)	- -	-	-	Solid (GHS definition)	FY2014	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0))
1	Acute toxicity (Inhalation: Vapours)	Not classified (Not applicable)	- -	-	-	Solid (GHS definition)	FY2014	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0))
1	Acute toxicity (Inhalation: Dusts and mists)	Not classified	- -	-	-	Since there is a report of an LC0 value (4 hours) for rats of >13.3 mg/L (OECD TG 403) (IUCLID (2000)), it was classified as "Not classified." Besides, because there is no data on vapor pressure and it cannot be assumed to be in the gas or vapor state, it was regarded as a test with the dust and its reference value was applied. Since the new information source (IUCLID (2000)) was added, and the category was revised.	FY2014	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0))
2	Skin corrosion/irritation	Classification not possible	- -	-	-	Classification not possible due to lack of data. In humans, there is 1 report that dermatitis was caused by exposure to trivalent chromium compounds and another report that it was not (EHC 61 (1988), ACGIH (7th, 2001)).	FY2014	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0))
3	Serious eye damage/eye irritation	Classification not possible	- -	-	-	Classification not possible due to lack of data. Besides, there is a description that particles of trivalent chromium compounds may irritate the eyes (Environmental Risk Assessment for Chemical Substances Vol.8 (Ministry of the Environment, 2010)).	FY2014	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0))
4	Respiratory sensitization	Category 1	Danger	H334	P304+P340 P342+P311 P261 P284 P501	Japan Society For Occupational Health (JSOH) classified chromium compounds including this substance in occupational sensitizers to the airway Group 2 (OEL Documentations (Japan Society For Occupational Health (JSOH), 1989)). On the other hand, it is described that there is at present no unequivocal evidence to show that exposure to trivalent chromium compounds has induced occupational asthma (CICAD 76 (2009)). According to the revised GHS classification guidance for the Japanese government, it is described that Group 1 and Group 2 in the Japan Society For Occupational Health (JSOH) are treated as equivalent to 1A. However, since this substance itself is not specified in OEL Documentations (Japan Society For Occupational Health (JSOH), 1989), subcategorization was not performed in this classification and it was classified in Category 1.	FY2014	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0))
4	Skin sensitization	Category 1	Warning	H317	P302+P352 P333+P313 P362+P364 P261 P272 P280 P321 P501	Japan Society For Occupational Health (JSOH) classified chromium compounds including this substance in occupational skin sensitizers Group 1 (OEL Documentations (Japan Society For Occupational Health (JSOH), 1989)). In addition, there is a report that after application of trivalent chromium to guinea pigs, sensitization was observed (EHC 61 (1988)). Moreover, there is a description that although trivalent chromium may act as an ultimate haptenic determinant, its poor skin penetration limits the sensitizing ability of trivalent chromium salts (CICAD 76 (2009)). According to the revised GHS classification guidance for the Japanese government, it is described that Group 1 and Group 2 in the Japan Society For Occupational Health (JSOH) are treated as equivalent to 1A. However, since this substance itself is not specified in OEL Documentations (Japan Society For Occupational Health (JSOH), 1989), subcategorization was not performed in this classification and it was classified in Category 1.	FY2014	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0))
5	Germ cell mutagenicity	Classification not possible	- -	-	-	Classification not possible due to lack of data. There are no in vivo data on this substance. As for in vitro data, there is only a negative result in a DNA damage test with Escherichia coli using chromium hydroxide (CICAD 76 (2009)).	FY2014	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0))
6	Carcinogenicity	Classification not possible	- -	-	-	Since it was classified in Group 3 (as Chromium (III)) by IARC (1990), in A4 (as Metal and Cr III compounds) by ACGIH (2008) and as D (Chromium (III), as insoluble salts) by EPA (1998), it was classified as "Classification not possible."	FY2014	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0))
7	Reproductive toxicity	Classification not possible	- -	-	-	Classification not possible due to lack of data.	FY2014	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0))
8	Specific target organ toxicity - Single exposure	Classification not possible	- -	-	-	There is little information on this substance, only a report that vomiting, abdominal tenderness and anaemia were observed in a woman who ingested 5 g of chromium hydroxide (Environmental Risk Assessment for Chemical Substances Vol.8 (Ministry of the Environment, 2010)). Classification not possible due to lack of data.	FY2014	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0))
9	Specific target organ toxicity - Repeated exposure	Classification not possible	- -	-	-	Classification not possible due to lack of data.	FY2014	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0))
10	Aspiration hazard	Classification not possible	- -	-	-	Classification not possible due to lack of data.	FY2014	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0))
