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, it is described in CICAD 34 (2001) that mortality observed 7 days after administration of 500 mg/kg of this substance (CAS RN not indicated) in rabbits was 62%.	FY2016	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
1	Acute toxicity (Dermal)	Classification not possible	- -	-	-	Classification not possible due to lack of data.	FY2016	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))

2	Skin corrosion/irritation	Classification not possible	- -	-	-	Classification not possible due to lack of data. 　Besides, strong dermal irritations were reported in guinea pigs dermally exposed to polychloronaphthalenes (CICAD 34 (2001)). Nevertheless, because the irritations could not be attributed specifically to this substance, this data was not adopted.	FY2016	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
3	Serious eye damage/eye irritation	Classification not possible	- -	-	-	Classification not possible due to lack of data. 　Besides, irritation of the eyes is reported in workers exposed to polychloronaphthalenes. Nevertheless, because it is noted that there had been a possible exposure to other chemicals (CICAD 34 (2001)), this data was not adopted.	FY2016	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
4	Respiratory sensitization	Classification not possible	- -	-	-	Classification not possible due to lack of data.	FY2016	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))

7	Reproductive toxicity	Classification not possible	- -	-	-	Classification not possible due to lack of data.	FY2016	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
8	Specific target organ toxicity - Single exposure	Classification not possible	- -	-	-	Classification not possible due to lack of data. 　There is no data on single exposure to this substance in humans and experimental animals. Besides, while there are descriptions that chlorinated naphthalenes exhibit hepatotoxicity (CICAD 34 (2001), DFGOT vol. 13 (1997)) and that symptoms in workers exposed to chlorinated naphthalenes included irritation of the eyes, fatigue, headaches, anaemia, haematuria, anorexia, vomiting, severe abdominal pain (CICAD 34 (2001)), none of these had information on the number of exposure times.	FY2016	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
9	Specific target organ toxicity - Repeated exposure	Category 1 (liver, skin)	Danger	H372	P260 P264 P270 P314 P501	There was no information with regard to this substance. 　Besides, as for humans, severe skin reactions (chloracne) and liver disease have both been reported in occupational exposure to chlorinated naphthalenes (CICAD 34 (2001), DFGOT vol. 13 (1997), ACGIH (7th, 2001)). It is reported that the toxicity varies depending on the degree of chlorination and studies in humans and animals had shown that toxicity was dependent on the congener/isomer, and that there is agreement in all studies that the penta- and hexa- isomers were the most toxic (CICAD 34 (2001)). 　With regard to effects on the skin, it is reported that chloracne was observed with trichloronaphthalenes and higher chlorinated naphthalenes (DFGOT vol. 13 (1997)). It is reported that the incidence and severity of chloracne were less when trichloronaphthalene (usually mixed with some tetrachloronaphthalene) was used than when penta- or hexachloronaphthalene was present (ACGIH (7th, 2001)). It is reported that in wire manufacturing plants, contact with a fabric impregnated with hexa- and pentachloronaphthalenes caused chloracne (ACGIH (7th, 2001)).Moreover, it is reported that after dermal application to volunteers, only Halowax 1014, containing penta- and hexachloronaphthalenes, produced chloracne, and Halowaxes containing mono-, di-, tri-, tetra-, hepta-, and/or octachloronaphthalenes did not (CICAD 34 (2001)). 　With regard to the effects on the liver, as information in which the substance is identified to some extent, a non-fatal case of hepatitis induced by occupational exposure to trichloronaphthalene (tetrachloronaphthalene was probably also present (CICAD 34 (2001))) at 3mg/m3 has been reported (ACGIH (7th, 2001)). On the other hand, as for higher chlorinated congeners, it is reported that in a workplace environment with concentrations of mixed pentachloronaphthalene and hexachloronaphthalene between 1 and 2 mg/m3, fatal cases of yellow atrophy of the liver occurred (ACGIH (7th, 2001)). 　As for information in experimental animals, it is reported that in medium-term toxicity experiments performed with technical mixtures of polychloronaphthalenes in rats and guinea pigs, liver damage (mainly enlarged liver cells with increased granularity and vacuolization) etc. were found and the higher chlorinated mixtures appeared to be more toxic (CICAD 34 (2001)). 　As described above, effects on the liver and skin by chlorinated naphthalenes were observed, and pentachloronaphthalene which has five chlorine atoms and hexachloronaphthalene which has six chlorine atoms are thought to be the major causal substances for the toxicity of chlorinated naphthalenes. However, it was thought that this substance which has seven chlorine atoms, while it was considered to exhibit less toxicity, also have similar target organs. Therefore, this substance was classified in Category 1 (liver, skin).	FY2016	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
10	Aspiration hazard	Classification not possible	- -	-	-	Classification not possible due to lack of data.	FY2016	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
