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.	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 was not adopted as the evidence for classification because the cause of the irritation was not specified to be this substance. Moreover, because the information adopted in the previous classification was from List 3 information sources and the original source 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, however, it was also pointed out that there had been a possible exposure to other chemicals (CICAD 34 (2001)), so it was not adopted as the evidence for classification. Moreover, because the information adopted in the previous classification was from List 3 information sources and the original source 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))
6	Carcinogenicity	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. 　Besides, it is described that in a developmental toxicity study using rats administered by gavage of 1 microg/kg of the isomer, 1,2,3,4,6,7-hexachloronaphthalene on Day 14-16 of gestation, no fetotoxicity or teratogenicity was observed in the fetuses, while for the offspring, accelerated onset of spermatogenesis was observed, including increase in testis weight on postnatal Day 31, increased testicular spermatids on Day 48, and increased sperm counts in the cauda epididymis in the male offspring (CICAD 34 (2001)).	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 are no data on single exposure of this substance in humans and experimental animals. Besides, there are descriptions that chlorinated naphthalenes exhibited hepatotoxicity (CICAD 34 (2001), DFGOT vol. 13 (1997)) and description that symptoms in workers exposed to chlorinated naphthalenes included irritation of the eyes, fatigue, headaches, anaemia, haematuria, anorexia, vomiting, and severe abdominal pain (CICAD 34 (2001)). None of these, however, 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	As for humans, it is reported that chloracne was observed from trichloronaphthalenes or higher chlorinated naphthalenes (DFGOT Vol. 13 (1997)). It is reported that, in dermal application to volunteers, only Halowax 1014, containing penta- and hexachloronaphthalenes, produced chloracne and Halowaxes containing mono-, di-, tri-, tetra-, hepta-, and octachloronaphthalene did not (CICAD 34 (2001)). 　Although it is not this substance alone, in the workplace environments with mixtures of this substance and pentachloronaphthalene between 1 and 2 mg/m3, fatalities due to yellow atrophy of the liver are reported (ACGIH (7th, 2001)). It is reported that in wire manufacturing plants, contact with fabrics impregnated with this substance and pentachloronaphthalene caused chloracne (ACGIH (7th, 2001)). 　As for experimental animals, there are no reports on this substance alone. 　However, in study using rats administered by inhalation with a mixture of this substance and pentachloronaphthalene of 0.00116 mg/L for 134 days (16 hours/day) or at 0.00144 mg/L (8 hours/day) for 143 days, liver damage (enlargement of liver cells, fatty vacuolization, granulation, mitotic figures) were reported. In studies using rats administered by inhalation at 0.00088 mg/L for 134 days (16 hours/day), death, jaundice, fatty degeneration of hepatocytes, and centrilobular necrosis were reported (CICAD 34 (2001), ACGIH (7th, 2001)). 　Those were all seen at the doses within the range of Category 1. 　Besides, it is reported that in medium-term experiments performed with technical mixtures of poly chlorinated naphthalenes in rats and guinea pigs, liver damage (mainly enlarged liver cells with increased granularity and vacuolization) etc. were found, but the higher chlorinated mixtures seemed to be more toxic (CICAD 34 (2001)). 　In addition, it is reported that studies in humans and animals demonstrated that the toxicity is dependent on the congener/isomer and that it is in agreement in all studies that the toxicity of penta- and hexa- chloronaphthalenes are the strongest (CICAD 34 (2001)). 　As described above, there are few reports on this substance alone. However, chlorinated naphthalenes affected the liver and skin, and this substance and hexachloronaphthalenes are thought to be major causal substances for the toxicity of the chlorinated naphthalenes. 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))
