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 2	Danger	H300	P301+P310 P264 P270 P321 P330 P405 P501	[Rationale for the Classification] Based on (1)-(3), it was classified in Category 2. [Evidence Data] (1) LD50 for rats: male: 89 mg/kg, female: 32 mg/kg (JMPR (1975)) (2) LD50 for rats: 89 mg/kg (IPCS, PIM G001 (1989)) (3) LD50 for rats: 28.5 mg/kg (GESTIS (Access on October 2019))	FY2019	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
1	Acute toxicity (Dermal)	Category 3	Danger	H311	P302+P352 P361+P364 P280 P312 P321 P405 P501	[Rationale for the Classification] Based on (1), it was classified in Category 3. The category was changed from the previous classification by using the new information sources. [Evidence Data] (1) LD50 for rats: male: >1,000 mg/kg, female: 640 mg/kg (JMPR (1975))	FY2019	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
1	Acute toxicity (Inhalation: Gases)	Not classified (Not applicable)	- -	-	-	[Rationale for the Classification] Solid (GHS definition). It was classified as "Not classified (Not applicable)."	FY2019	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
1	Acute toxicity (Inhalation: Vapours)	Classification not possible	- -	-	-	[Rationale for the Classification] Classification not possible due to lack of data.	FY2019	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
1	Acute toxicity (Inhalation: Dusts and mists)	Classification not possible	- -	-	-	[Rationale for the Classification] Classification not possible due to lack of data.	FY2019	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))

3	Serious eye damage/eye irritation	Classification not possible	- -	-	-	[Rationale for the Classification] Although there are data in (1) and (2), these are insufficient data for classification, therefore, it was classified as "Classification not possible." [Reference Data, etc.] (1) In an eye irritation test in which 0.05 mL of a suspension of this substance in Tween 80 was administered to the eyes of rabbits, it was irritating at or above 0.2%, and congestion of the conjunctiva and lacrimation were observed at 1%, but no abnormalities were observed in the cornea, corneal reflex, conjunctival reflex and pupil diameter (JMPR (1975)). (2) It was classified as "Eye Irrit. 2 (H319)" in the EU-CLP classification (EU CLP classification (Access on October 2019)).	FY2019	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
4	Respiratory sensitization	Classification not possible	- -	-	-	[Rationale for the Classification] Classification not possible due to lack of data.	FY2019	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
4	Skin sensitization	Classification not possible	- -	-	-	[Rationale for the Classification] Although there are data in (1), these are insufficient data for classification, therefore, it was classified as "Classification not possible." [Reference Data, etc.] (1) No significant changes were observed in a skin sensitization test with guinea pigs (intradermal sensitization: 1% and 5% solutions of this substance every other day for 20 days, challenge by intradermal administration and topical application 14 days after the final sensitization) (JMPR (1975)).	FY2019	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
5	Germ cell mutagenicity	Classification not possible	- -	-	-	[Rationale for the Classification] There are no in vivo data, therefore, classification was not possible due to lack of data. [Evidence Data] (1) As for in vitro, negative results were reported in bacterial reverse mutation tests (JMPR (1980)).	FY2019	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
6	Carcinogenicity	Classification not possible	- -	-	-	[Rationale for the Classification] Classification not possible due to lack of data.	FY2019	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	[Rationale for the Classification] Based on (1), reproductive effects were observed over three generations, but the extent of the effects is unknown. Therefore, there is some evidence of reproductive toxicity, and it was classified in Category 2. The classification result was changed from the previous classification by the use of new information. [Evidence Data] (1) In a 3-generation reproductive toxicity test with rats dosed by feeding, reduced mating indices (third generation (F3): first parents (first generation) defined as F1), lowered male and female fertility (second generation (F2) and third generation (F3)), and reduced pup viability (unknown from which parental generation they were) were observed at the dose where no parental toxicity was observed (JMPR (1975)). [Reference Data, etc.] (2) In a developmental toxicity test with female rabbits administered by gavage on gestational Days 6-18, no developmental effects were observed (JMPR (1975)).	FY2019	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
8	Specific target organ toxicity - Single exposure	Classification not possible	- -	-	-	[Rationale for the Classification] Classification not possible due to lack of data. Based on (1), the possibility of effects on the nervous system was considered. However, since there were no descriptions of acute toxicity symptoms from this substance in evaluation reports listed in List 1 or List 2, and a literature search did not provide information to support neurotoxicity by single exposure, therefore, it was classified as "Classification not possible." [Reference Data, etc.] (1) This substance is an organophosphorus pesticide. The mode of action of organophosphorus pesticides was described to be inhibition of acetylcholinesterase (IPCS, PIM G001 (1989)).	FY2019	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
9	Specific target organ toxicity - Repeated exposure	Category 1 (nervous system)	Danger	H372	P260 P264 P270 P314 P501	[Rationale for the Classification] Based on (1) and (2), it was classified in Category 1 (nervous system). After the review using the new information sources, the classification result was changed from the previous classification. [Evidence Data] (1) In a 12-month repeated dose toxicity test with dogs dosed by feeding, ataxia of the hindquarters, increased liver to body and brain weight ratio, and decreased plasma and red blood cell cholinesterase activities were observed at 100 ppm (converted guidance value: 2.5 mg/kg/day, within the range of Category 1) (JMPR (1975)). (2) In a 24-month repeated dose toxicity test with rats dosed by feeding, depressed plasma, red blood cell and brain cholinesterase activities were observed in females at or above 50 ppm (converted guidance value: 2.5 mg/kg/day, within the range of Category 1) and in males at or above 100 ppm (converted guidance value: 5 mg/kg/day, within the range of Category 1) (JMPR (1975)).	FY2019	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
10	Aspiration hazard	Classification not possible	- -	-	-	[Rationale for the Classification] Classification not possible due to lack of data.	FY2019	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
