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	- -	-	-	Its publicized rat LD50 values, 12.7-18.14 g/kg (PATTY (5th, 2001)) and 14.8 g/kg bw (PATTY (5th, 2001)), both fall under the "Not classified" category.	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
1	Acute toxicity (Dermal)	Not classified	- -	-	-	Its rabbit LD50 value, > 9.1 g/kg bw (PATTY (5th, 2001), HSDB (2002)), falls under the "Not classified" category.	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
1	Acute toxicity (Inhalation: Gases)	Not classified (Not applicable)	- -	-	-	Liquid (GHS definition)	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
1	Acute toxicity (Inhalation: Vapours)	Category 4	Warning	H332	P304+P340 P261 P271 P312	Since its rat LC50 is 8300 ppm/4h (HSDB (2002)), the substance was classified into Category 4. As this study was conducted under the condition in which the LD50 is <= 90% of its saturated vapour pressure, evaluation was carried out using criteria for gases.	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
1	Acute toxicity (Inhalation: Dusts and mists)	Classification not possible	- -	-	-	No data available.	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
2	Skin corrosion/irritation	Classification not possible	- -	-	-	There is a description of human cases in which the substance causes allergic contact dermatitis (PATTY (5th, 2001)). However, classification is not possible based on this information alone.	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
3	Serious eye damage/eye irritation	Classification not possible	- -	-	-	No data available.	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
4	Respiratory sensitization	Classification not possible	- -	-	-	No data available.	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
4	Skin sensitization	Category 1	Warning	H317	P302+P352 P333+P313 P362+P364 P261 P272 P280 P321 P501	Guinea pig maximization tests gave positive results (DFGOT vol. 16 (2001)). In addition, patch tests found positive results in dermatitis patients (some of them developed occupation-related dermatitis) and people who have been exposed to ethyl methacrylate or those who are suspected to have been exposed to it (DFGOT vol. 16 (2001)). Based on this information, the substance was classified into Category 1.	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
5	Germ cell mutagenicity	Classification not possible	- -	-	-	No data available.	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
6	Carcinogenicity	Classification not possible	- -	-	-	No data available.	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
7	Reproductive toxicity	Classification not possible	- -	-	-	In rats that underwent intraperitoneal administration, signs of fetal toxicity and teratogenicity were noted (PATTY (5th, 2001), Birth Defects (3rd, 2000)). On the other hand, there is a description that inhalation exposure did not cause embryonic lethality or teratogenic efffects (SIDS (J) accessed in September 2008). Some results were based on intraperitoneal administration tests; in addition, only limited information is available and we cannot verify the consistency of test results. Thus, classification is not possible.	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
8	Specific target organ toxicity - Single exposure	Category 3 (Respiratory tract irritation)	Warning	H335	P304+P340 P403+P233 P261 P271 P312 P405 P501	In oral administration tests using rats, respiratory system disorder was noted at administrations of 12.7-18.14 g/kg, which fall under the "Not classified" category guidance values; and in inhalation tests using rats, respiratory tract irritation was induced (PATTY (5th, 2001)). In addition, it is documented that vapour of the substance may cause irritation to mucous membrane in humans and exposure to monomers of the substance may cause central nervous system disorder (PATTY (5th, 2001)). It is rated as R37 in the EU classification. Based on these pieces of information, the substance was classified into Category 3 (respiratory tract irritation).	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
9	Specific target organ toxicity - Repeated exposure	Classification not possible	- -	-	-	In 60-day oral administration tests using rats, degeneration of the brain and spinal cord was noted at 6570 and 600 mg/kg, which are above Category 2 guidance doses (RTECS (2008)). However, since these results were obtained using List 3 datasets, and due to insufficient data available, classification is not possible.	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
10	Aspiration hazard	Classification not possible	- -	-	-	No data available.	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
