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)	Classification not possible	- -	-	-	Classification not possible due to lack of data. Besides, there is a report of an LD50 value of 140 mg/kg for rats (GESTIS (Access on September 2014)). However, since it is information in List 3, and it was not possible to confirm the original source, it was classified as "Classification not possible." The information source was changed, and the category was revised.	FY2014	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0))
1	Acute toxicity (Dermal)	Not classified	- -	-	-	There are 2 reports of LD50 values of >2,000 mg/kg (male) and >1,224 mg/kg (female) for rats (SIDS (2006)). They corresponded to "Not classified" or "Classification not possible," respectively, therefore, it was classified as "Not classified." A new information source (SIDS (2006)) was added, and the category was revised.	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)	Classification not possible	- -	-	-	Classification not possible due to lack of data. Since no data for evidence in the previous classification was registered, 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. Besides, there is a description that hardness and crust on the application site were observed in an acute toxicity test (OECD TG 402) in which this substance was dermally applied for 24 hours (SIDS (2006)), therefore, it may be irritating to the skin.	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 copper compounds cause conjunctivitis, ulceration and turbidity of the cornea in the eye (ACGIH (7th, 2001)). However, the data was judged insufficient for use in the classification since specific information such as substance information was unknown.	FY2014	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0))
4	Respiratory sensitization	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))
4	Skin sensitization	Category 1	Warning	H317	P302+P352 P333+P313 P362+P364 P261 P272 P280 P321 P501	There are neither reports of test results in experimental animals nor epidemiological studies regarding skin sensitization. However, Japan Society For Occupational Health (JSOH) designated copper as occupational skin sensitizers Group 2 (although it indicates the substance itself or its compound, the evaluation does not necessarily apply to all individual chemicals within the group), therefore, 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	- -	-	-	It was classified as "Classification not possible" because it was not possible to classify a substance as "Not classified" according to the revised GHS classification guidance for the Japanese government. As for in vivo, it was negative in a mouse bone marrow micronucleus test (SIDS (2006)). As for in vitro, it was negative in a bacterial reverse mutation test, and it was positive in a chromosomal aberration test with cultured mammalian cells (SIDS (2006), DFGOT vol. 22 (2006)).	FY2014	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0))
6	Carcinogenicity	Classification not possible	- -	-	-	EPA classified this substance as D (IRIS (Access on October 2014)). From the above, 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. There is a report that in a combined repeated dose toxicity study with the reproduction/developmental toxicity screening test (OECD TG 422) with rats by the oral route (gavage), at a dose where parental toxicity (death in 3/12 animals, anemia, squamous cell hyperplasia in the forestomach) was observed, no effects on fertility were observed. However, icterus (3/120 animals, 3/9 maternal animals) and runts (2/120 animals, 2/9 maternal animals) were observed in pups (SIDS (2006)). However, maternal toxicity was pronounced, therefore, it was not adopted as evidence for classification.	FY2014	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0))
8	Specific target organ toxicity - Single exposure	Classification not possible	- -	-	-	Since there were no data on this substance, it was classified as "Classification not possible." Besides, it was reported that by the inhalation exposure to copper dusts and mists in humans, irritation of the respiratory tract, coughing, nausea, headache, gastric pain, vomiting, hemorrhagic gastritis, diarrhea and symptoms similar to metal fume fever were observed. In addition, there is a description of gastrointestinal tract irritation, nausea, vomiting and diarrhea by the oral ingestion of metal copper in humans (ACGIH (7th, 2001), DFGOT vol. 22 (2006)).	FY2014	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0))
9	Specific target organ toxicity - Repeated exposure	Category 2 (blood system)	Warning	H373	P260 P314 P501	There is no hazardous knowledge by exposure to this substance in humans. In a combined repeated dose toxicity study with the reproduction/developmental toxicity screening test in which rats were given this substance orally (gavage), squamous cell hyperplasia of the forestomach was observed at a dose (5 mg/kg/day (converted guidance value: equivalent to about 1.7 mg/kg/day)) corresponding to Category 1 and hematotoxicity effects (decreases in red blood cell count, hemoglobin concentration and hematocrit, increases in white blood cell count, neutrophil ratio and platelet count, bone marrow hyperplasia of the femur) were observed at a dose (80 mg/kg/day (converted guidance value: equivalent to about 26.7 mg/kg/day)) corresponding to Category 2 (SIDS (2006)). Since it was considered that the former is due to the irritating effect on the mucosa from copper and was not included in relevant findings to determine target organs, it was classified in Category 2 (blood system).	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))

ENVIRONMENTAL HAZARDS
