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)	Category 4	Warning	H302	P301+P312 P264 P270 P330 P501	Based on a 100% fatal dose (1,800 mg/kg) and a 100% survival dose (400 mg/kg) for guinea pigs (HSDB (Access October 2016)), it was classified in Category 4.	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))
1	Acute toxicity (Inhalation: Gases)	Not classified (Not applicable)	- -	-	-	Solid (GHS definition)	FY2016	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
1	Acute toxicity (Inhalation: Vapours)	Not classified (Not applicable)	- -	-	-	Solid (GHS definition)	FY2016	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
1	Acute toxicity (Inhalation: Dusts and mists)	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)). However, this report was not adopted because this substance could not be identified as the cause of the irritation. Moreover, because the information adopted in the previous classification was from List 3 information sources and the original literature could not be confirmed, it 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 was reported in workers exposed to polychloronaphthalenes, but it was also suggested that there had been a possible exposure to other chemicals (CICAD 34 (2001)), therefore, this was not adopted. Moreover, because the information adopted in the previous classification was from List 3 information sources and the original literature could not be confirmed, it 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))
4	Skin 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))
5	Germ cell mutagenicity	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, there are descriptions that chlorinated naphthalenes exhibit hepatotoxicity (CICAD 34 (2001), DFGOT vol. 13 (1997)) and a description that symptoms in workers exposed to chlorinated naphthalenes included irritation of the eyes, fatigue, headaches, anaemia, haematuria, anorexia, vomiting, severe abdominal pain etc. (CICAD 34 (2001)). None of these, however, had information on 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 is no information with regard to this substance. 　Besides, 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 amount of chlorination, and that 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)). 　Among them, with regard to effects on the skin, it was reported that chloracne was observed with this substance and higher chlorinated naphthalenes (DFGOT Vol. 13 (1997)). It was reported that in the case of chloracne from use of this substance (usually mixed with some tetrachloronaphthalene), the incidence and severity were less than chloracne produced by penta- and hexachloronaphthalene (ACGIH (7th, 2001)). It was also 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 octachloronaphthalenes did not (CICAD 34 (2001)). With regard to 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 this substance (tetrachloronaphthalene was probably also present (CICAD 34 (2001)) at 3mg/m3 was reported (ACGIH (7th, 2001)). On the other hand, as for higher chlorinated congeners, it was reported that fatal cases of yellow atrophy of the liver occurred in workplace environments with concentrations of mixed pentachloronaphthalene and hexachloronaphthalene between 1 and 2 mg/m3 (ACGIH (7th, 2001)). 　As for experimental animals, in toxicity tests using rats by inhalation of this substance (with a small amount of tetrachloronaphthalene) for 2.5 months (1,232 hours) or 4 months (1,896 hours), very slight swelling of the liver at 0.0013 mg/L, which is within the range of Category 1, and hepatic hypertrophy and granulocytosis along with mitotic figures at 0.011 mg/L were observed (ACGIH (7th, 2001)). 　Besides, it was 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 appear to be more toxic (CICAD 34 (2001)). 　As described above, chlorinated naphthalenes affected the liver and skin, and pentachloronaphthalene which has five chlorine atoms and hexachloronaphthalene which has six chlorine atoms were thought to be the major causal substances for the toxicity of chlorinated naphthalenes. There is no information exclusively on this substance. However, it is thought that this substance which has three chlorine atoms, while considered to exhibit less toxicity, also has 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))
