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	From a description of LD50 value of 470 mg/kg (DFGOT vol.19 (1998), ACGIH (7th, 2001)) in the oral administration test employing rats, it was classified into Category 4.	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
1	Acute toxicity (Dermal)	Not classified	- -	-	-	There is description of LD50 value 3,300 mg/kg of the dermal administration test employing a rabbit (DFGOT vol.19 (1998)). Although LD50 value seemed to be equivalent to the U.N. GHS acute toxicity (dermal) Category 5, it fell under unadopted category in Japan and was classified into "Not classified".	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
1	Acute toxicity (Inhalation: Gases)	Not classified (Not applicable)	- -	-	-	Since it was a solid by the definition of GHS and inhalation in gas was not assumed, it was classified into "Not applicable".	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
1	Acute toxicity (Inhalation: Vapours)	Classification not possible	- -	-	-	Classification not possible due to lack of data	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
1	Acute toxicity (Inhalation: Dusts and mists)	Category 4	Warning	H332	P304+P340 P261 P271 P312	Saturated vapor pressure level of this substance (25degC)is 175 ppm (0.867 mg/L). Since LC50 value with 1.53 mg/L of the 4-hour inhalation exposure test employing rats (DFGOT vol.19 (1998)) was larger than saturated vapor pressure level, it was classified into Category 4 by applying the mist standard.	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
2	Skin corrosion/irritation	Not classified	- -	-	-	It is described as "not irritating" (DFGOT Vol. 19 (1998)).for the skin irritation test comforming to OECD TG. Moreover, it is described as "skin: weak irritation" in BUA 161 (Summary, 1994). Although it seemed to correspond to UN GHS Skin irritation Category 3 based on the above-mentioned, it was classified into "Not classified", because Category 3 is not domestically adopted. In addition, there is a description, "It stimulates the skin.........causes reddening, when contacting the skin" in the section of Effects on Humans of the MOE Risk Assessment Vol 6 (2008). Moreover, there is a description "mildly irritating" in the section of EFFECTS OF SHORT-TERM EXPOSURE in the cited literature ICSC (2007).	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
3	Serious eye damage/eye irritation	Category 2	Warning	H319	P305+P351+P338 P337+P313 P264 P280	In the eye irritation examination in conformity to OECD TG, it has been described as "irritating" (DFGOT vol.19 (1998)). Moreover, it is described as "eye: irritant" in BUA 161 (Summary, 1994). As mentioned above, since the degree was unknown, it was not classified finely and was classified into "Category 2". In addition, the clause of influence in MOE Risk Assessment, Volume 6 (2008) describes as "It irritates the eye, and ... when it goes into the eye, redness and pain are caused." Moreover, it is described as "irritating" in the clause of EFFECTS OF SHORT-TERM EXPOSURE of ICSC (2007) which is a cited literature.	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
4	Respiratory sensitization	Classification not possible	- -	-	-	Classification is not possible since there is no data.	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
4	Skin sensitization	Classification not possible	- -	-	-	Classification is not possible since there is no data.	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
5	Germ cell mutagenicity	Classification not possible	- -	-	-	Although there is a description of "positive" in the in vitro mutagenicity test (Ames test employing a Salmonella typhimurium) (NTP DB (Access on October 2008)), classification is not possible because there is no data of in vivo examination.	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
6	Carcinogenicity	Not classified	- -	-	-	Since IARC has a description of group 3 (IARC Suppl.7 (1987)), it was classified into "Not classified" according to guidance. However, it is classified into the Category 2 (DFGOT vol.19 (1998)) in Germany DFG.	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
7	Reproductive toxicity	Classification not possible	- -	-	-	Classification not possible due to lack of data	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
8	Specific target organ toxicity - Single exposure	Category 1 (blood system)	Danger	H370	P308+P311 P260 P264 P270 P321 P405 P501	For animals, there is a description of "Hyperpnea was seen." in 4 hours inhalation exposure test employing rats (DFGOT vol.19 (1998)), and there is a description of "Methemoglobin was produced about 1 hour and a half after administration" in the oral administration test where the lethal dose in rats were calculated (DFGOT vol.19 (1998)). All these symptoms were seen within the range of the guidance value of Category 1. Although there is no data of this substance on the humans, the report that "2,6-xylidine, which is an isomer, caused methemoglobinemia on humans." is described in DFGOT vol.19 (1998). As mentioned above, it was classified into Category 1 (blood systems). In addition, in ICSC (2007), "The high concentration exposure may cause lowering of consciousness. The high concentration exposure may produce methemoglobin. These effects may occur backwardly. Although there is a description of "Medical follow up is needed, the details of doses are unknown.	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
9	Specific target organ toxicity - Repeated exposure	Category 1 (blood system, liver)	Danger	H372	P260 P264 P270 P314 P501	Within the limits of the guidance value of Category 1, "an increase in relative and absolute liver weight, an increase in hyaline droplet on the epithelium of kidney tubules of kidney, a decrease in the amount of hemoglobin, an increase in the platelet count and an increase in activated partial thromboplastin time were observed in male rats, and an increase in the amount of total cholesterol was observed in female rats, as well as hypertrophy of hepatocytes at the center of the hepatic lobule was observed both in male and female rats."(MOE Risk Assessment vol. 6 (2008)) Within the limits of the guidance value of Category 2, "an increase in relative and absolute liver weight, an increase in relative kidney weight, a decrease in the amount of hemoglobin and a decrease in the prothrombin time were observed in female rats" (MOE Risk Assessment vol. 6 (2008)). About the effects on the liver, from description in ACGIH (7th, 2001) that "hepatocellular necrosis and bile duct hyperplasia were observed in male rats" within the limits of the guidance value of Category 2, they are adopted to categorize. Since an increase in hyaline droplet on the epithelium of kidney tubules of kidney was only observed in male rats, it is not adopted to categorize. Therefore, it is classified into Category 1 (blood systems, liver).	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
10	Aspiration hazard	Classification not possible	- -	-	-	Classification not possible due to lack of data	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
