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 report of an LD50 value of 1,500 mg/kg for rats (PATTY (6th, 2012), SIDS (2008), IUCLID (2000)), it was classified in Category 4.	FY2014	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0))
1	Acute toxicity (Dermal)	Not classified	- -	-	-	Based on a report of an LD50 value of >4,000 mg/kg for rats (PATTY (6th, 2012), IUCLID (2000)), it was classified as "Not classified."	FY2014	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0))
1	Acute toxicity (Inhalation: Gases)	Not classified (Not applicable)	- -	-	-	Liquid (GHS definition)	FY2014	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0))
1	Acute toxicity (Inhalation: Vapours)	Classification not possible	- -	-	-	Classification not possible due to lack of data. Besides, there was a report of an LC50 value (4 hours) of >5.2 mg/L (2,115 ppm) for rats (PATTY (6th, 2012), SIDS (2008), IUCLID (2000)). Since the LC50 value was lower than 90% of the saturated vapor concentration, 671,786 ppm, it was regarded as a vapour without a mist. Since it was not possible to identify either Category 3, Category 4, or "Not classified" from this LC50 value, it was classified as "Classification not possible." Instead of a low-priority information source (RTECS (2004)), new high-priority information sources (PATTY (6th, 2012), SIDS (2008), IUCLID (2000)) were added, and the category was revised.	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.	FY2014	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0))
2	Skin corrosion/irritation	Category 2	Warning	H315	P302+P352 P332+P313 P362+P364 P264 P280 P321	There is a description that the vapour of this substance was strongly irritating to humans (PATTY (6th, 2012)). In reports on animals, there are reports that in a test in which the undiluted liquid of this substance was applied occlusively to rabbits, the primary irritation score was 0.67 (SIDS (2008)), and that it was slightly irritating (SIDS (2008)). From the above, although it was equivalent to "Not classified" in reports on animals, there is a description that the vapour was strongly irritating to humans, therefore, it was changed to Category 2.	FY2014	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0))
3	Serious eye damage/eye irritation	Category 2	Warning	H319	P305+P351+P338 P337+P313 P264 P280	There is a report that in a test in which the undiluted liquid of this substance was applied to rabbits, mild to moderate corneal opacity (2/3 animals), iritis with Grade 1 (2/3 animals), conjunctival redness with Grade 2 (2/3 animals), erythema with Grade 1 (2/3 animals) and eye discharge with Grade 2 or 3 (2/3 animals) were observed and it was slightly irritating (SIDS (2008)). In addition, in another test with rabbits, moderate corneal damage with iritis was observed and it was considered irritating (SIDS (2008)). Moreover, irritation was observed in a test where guinea pigs were exposed to the vapor of this substance (PATTY (6th, 2012)). Furthermore, there is a description that it was also irritating to the eyes in humans (PATTY (6th, 2012)). From the above results, it was classified in Category 2.	FY2014	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0))

4	Skin 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))
5	Germ cell mutagenicity	Classification not possible	- -	-	-	Classification not possible due to lack of data. There was no in vivo data. As for in vitro, it was negative in bacterial reverse mutation tests (SIDS (2008), IUCLID (2000), PATTY (6th, 2012), NTP DB (Access on July 2014)).	FY2014	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0))
6	Carcinogenicity	Classification not possible	- -	-	-	There was no classification by international organizations. Classification was not possible due to lack of data.	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.	FY2014	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0))
8	Specific target organ toxicity - Single exposure	Category 1 (central nervous system, respiratory organs), Category 3 (narcotic effects)	Danger Warning	H370 H336	P308+P311 P260 P264 P270 P321 P405 P501 P304+P340 P403+P233 P261 P271 P312	In humans, inhalation exposure caused nose irritation, narcotic effects and dyspnea, and exposure to high concentrations caused convulsions and death. In addition, there is also a report that visual disturbances were caused (ACGIH (7th, 2001), HSDB (Access on June 2014), PATTY (6th, 2012)). As for inhalation exposures in experimental animals, unkempt fur, forced breathing, gasping, poor coordination, prostration, lacrimation, salivation and pulmonary congestion with some scattered hemorrhages in rats, nasal irritation, eye irritation, pulmonary irritation, narcosis, incoordination and central nervous system depression in guinea pigs, pulmonary inflammation and pulmonary edema in cats were found, and by oral administration to rats, dyspnea, apathy, stagger, sluggishness, gasping, pulmonary hemorrhages, and discolored liver, spleen, kidneys, stomachs and intestines were observed. By dermal application, it is reported that staggering and irregular breathing were caused in rats (SIDS (2008), ACGIH (7th, 2001), PATTY (6th, 2012), HSDB (Access on June 2014)). These findings were within the guidance range values corresponding to Category 1 or Category 2. Besides, discolored liver, spleen, kidneys, stomach and intestines were not adopted as organ toxicities since there was no specific information. From the above, it was classified in Category 1 (central nervous system, respiratory organs), Category 3 (narcotic effects).	FY2014	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0))
9	Specific target organ toxicity - Repeated exposure	Category 2 (respiratory organs)	Warning	H373	P260 P314 P501	The findings in humans were only information on acute exposures. Data on experimental animals were also very limited. And, there is only information that in a study in which rats were exposed by inhalation to the vapour of this substance for 2 weeks, tissue changes in the nasal epithelium (degeneration of the olfactory epithelium, squamous metaplasia, infiltration of inflammatory cells) were observed at or above 1.24 mg/L (converted guidance value: 0.19 mg/L/6 hours) (SIDS (2008)). It was classified in Category 2 (respiratory organs) because there was no finding on inhalation exposure in humans, and because in the inhalation exposure test with rats, a short administration period was adopted, and the effects were observed at or above the upper limit concentration of the range of Category 1. Besides, new information was added for this classification, and the category was revised.	FY2014	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0))
10	Aspiration hazard	Classification not possible	- -	-	-	Although the kinematic viscosity at room temperature calculated from the listed data in HSDB (Access on June 2014) was 0.329 mm2/s, there is no description that it induced an aspiration hazard in humans, and it is not a hydrocarbon, therefore, its category was not assigned. It was classified as "Classification not possible" due to lack of information.	FY2014	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0))
