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)	Not classified	- -	-	-	Based on the reports of LD50 values for rats of 2,572 m/kg, 3,078-3,200 mg/kg, 4,100 mg/kg (PATTY (6th, 2012)), 3,200 mg/kg (ACGIH (7th, 2011)), and 4,509 mg/kg (PATTY (6th, 2012), ACGIH (7th, 2011)), the substance was classified as "Not Classified" (Category 5 in UN GHS classification).	FY2015	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
1	Acute toxicity (Dermal)	Not classified	- -	-	-	Based on the reports of LD50 values for rabbits of 5,112 mg/kg (PATTY (6th, 2012), ACGIH (7th, 2011)) and > 5,000 mg/kg (PATTY (6th, 2012)), this substance was classified as "Not classified."	FY2015	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
1	Acute toxicity (Inhalation: Gases)	Not classified (Not applicable)	- -	-	-	Liquid (GHS definition)	FY2015	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
1	Acute toxicity (Inhalation: Vapours)	Category 4	Warning	H332	P304+P340 P261 P271 P312	Based on a report of an LC50 value (6 hours) for rats of 6,377 ppm (converted 4-hour equivalent value: 7,810 ppm) (PATTY (6th, 2012)), it was classified in Category 4. Besides, since the LC50 value was lower than 90% of the saturated vapor pressure concentration (68,684 ppm), the reference values in the unit of ppm was applied as vapor without mist. The classification was revised.	FY2015	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.	FY2015	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
2	Skin corrosion/irritation	Category 2	Warning	H315	P302+P352 P332+P313 P362+P364 P264 P280 P321	This substance was classified in Category 2 based on a description that it is irritating to human skin (HSDB (Access on August 2015)). Besides, there is a report that as a result of application of this substance (undiluted) to rabbits for 24 hours, moderate irritation was observed (PATTY (6th, 2012)), and there is another report that the application of this substance (undiluted) to guinea pigs for 24 hours resulted in moderate irritation, and after 24 hours, edema and necrosis were observed (PATTY (6th, 2012)). However, these were not adopted for the classification because they are 24-hour application tests.	FY2015	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
3	Serious eye damage/eye irritation	Category 2B	- Warning	H320	P305+P351+P338 P337+P313 P264	It is reported that in an eye irritation test with rabbits, mild irritation was observed but resolved within 7 days (PATTY (6th, 2012)) and there is a description that this substance caused irritation to human eyes (HSDB (Access on August 2015)). Based on the description in the report on rabbits that it was reversible within 7 days, this substance was classified as Category 2B.	FY2015	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.	FY2015	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. Besides, it is reported that sensitization was not observed in a sensitization test with guinea pigs (PATTY (6th, 2012)) and there is a report that as a result of human patch tests on 25 persons, sensitization was not observed (PATTY (6th, 2012)). However, these were judged to be inadequate data for use in classification because the details such as information on the test method and the control group are unknown.	FY2015	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.	FY2015	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
6	Carcinogenicity	Classification not possible	- -	-	-	Since there are no classification results by other organizations, classification was not possible due to lack of data.	FY2015	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
7	Reproductive toxicity	Category 2	Warning	H361	P308+P313 P201 P202 P280 P405 P501	In a reproduction/developmental toxicity screening test by the inhalation route with rats, there is a description that in the parent animals, dose-dependent reduction in activity during exposure at or above 1,000 mg/m3, and reduced body weight gain or decreased food consumption before mating or during the gestation period at 2,500-5,000 mg/m3 were observed, but no adverse effects on the genetic organs were observed. On the other hand, there is a description that in pups, an increased number of dead pups per litter on postnatal day 0 or day 4 at or above 2,500 mg/m3 and a decreased litter size at 5,000 mg/m3 were observed (ACGIH (7th, 2011)). It is a screening test, but at the dose at which general toxic effects were observed in the parent animals, a developmental toxicity effect indicated by the increased number of dead pups before or after birth was shown in the pups. Therefore, it was classified in Category 2 for this hazard class. Besides, ACGIH (7th, 2001) was available in the previous classification, but this data was not quoted in it, and in this reclassification, for this hazard class, data available for classification were obtained for the first time.	FY2015	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
8	Specific target organ toxicity - Single exposure	Category 3 (respiratory tract irritation, narcotic effects)	Warning	H335 H336	P304+P340 P403+P233 P261 P271 P312 P405 P501	This substance shows respiratory tract irritation in humans (ACGIH (7th, 2011), PATTY (6th, 2012)). In experimental animals, there is a report on central nervous system depression and narcotic effects by inhalation exposure in rats (ACGIH (7th, 2011), PATTY (6th, 2012)). From the above, it was classified in Category 3 (respiratory tract irritation, narcotic effects).	FY2015	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
9	Specific target organ toxicity - Repeated exposure	Classification not possible	- -	-	-	Classification not possible due to lack of data.	FY2015	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
10	Aspiration hazard	Classification not possible	- -	-	-	Findings directly showing respiratory hazards due to aspiration in humans were not obtained from information sources in List 1 and List 2. However, there is a description in ICSC listed as List 3 that if this substance is swallowed, vomiting may occur and there is a danger of aspiration pneumonitis (ICSC (2013), ICSC (J) (2013)), but it was thought that this was not directly based on hazard cases in humans but expressed a presumed concern from the acute exposure effects in humans and the physicochemical properties. Besides, this substance belongs to ketones composed of carbon atoms not less than 3 and not more than 13, and based on numerical data (viscosity: 0.5 mPa*s (16 deg C), density (specific gravity): 0.81 g/cm3 (20 deg C)) in GESTIS (Access on August 2015) of List 3, the calculated kinematic viscosity is 0.617 mm2/sec (16/20 deg C). Based on the above, although it corresponds to Category 2 in the UN GHS classification, this substance was classified as "Classification not possible" according to the current guidance revised after the previous classification.
