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 LD50 value of 817 mg/kg for rats (EHC 201 (1998)), the substance was classified into Category 4. [In this test, industrial bulk which contains 1 - 8% of bis (chloromethyl) ether as impurity was used.]	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）
1	Acute toxicity (Dermal)	Classification not possible	- -	-	-	No data available.	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）
1	Acute toxicity (Inhalation: Gases)	Not classified (Not applicable)	- -	-	-	Liquid (GHS definition)	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）
1	Acute toxicity (Inhalation: Vapours)	Category 1	Danger	H330	P304+P340 P403+P233 P260 P271 P284 P310 P320 P405 P501	Based on a LC50 value of 0.181 mg/L/7h (4-hour equivalence: 0.239 mg/L (72.2 ppmV)) for rats (EHC 201 (1998)), the substance was classified into Category 1. Since the test was conducted at lower than 90% of saturated vapour pressure concentration, the classification criteria for gas was adopted.	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）
1	Acute toxicity (Inhalation: Dusts and mists)	Classification not possible	- -	-	-	No data available.	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）

FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）
3	Serious eye damage/eye irritation	Category 1	Danger	H318	P305+P351+P338 P280 P310	Since there is a report that application to animal eyes resulted in corneal necrosis (EHC 201 (1998)) and the substance is classified into Category 1 for skin irritation, the substance was classified into Category 1.	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）
4	Respiratory sensitization	Classification not possible	- -	-	-	No data available.	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）
4	Skin sensitization	Classification not possible	- -	-	-	No data available.	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）
5	Germ cell mutagenicity	Category 2	Warning	H341	P308+P313 P201 P202 P280 P405 P501	Since mouse micronucleus tests showed both positive and negative results, the mutagenicity is considered to be "inconclusive" (Mutat Res., 389, 3-122, 1997). In epidemiological research, the frequency of chromosomal aberrations in the peripheral lymphocytes of 77 exposed workers was approximately twice that found for 25 unexposed control workers (in vivo somatic cell mutagenicity test) (CaPSAR (1993), EHC 201 (1998)). There are reports of positive Ames and MLA tests (Mutat Res., 389, 3-122, 1997). Based on positive results from human epidemiological research, Ames test and MLA test, the substance was classified into Category 2. As relevant information, there is a report that the substance increased unscheduled DNA synthesis in a human lymphocyte unscheduled DNA synthesis test (in vitro genotoxicity test) (EHC 201 (1998)).	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）
6	Carcinogenicity	Category 1A	Danger	H350	P308+P313 P201 P202 P280 P405 P501	Based on the classification of "Group 1" in IARC (IARC suppl. 7 (1987)) and "A" in EPA (IRIS (2005)), the substance was classified into Category 1A. As relevant information, the substance is classified into Category 2A (industrial) in Japan Society For Occupational Health (JSOH) (Recommendations for allowable concentrations (2008)) and "A2" in ACGIH (ACGIH-TLV (2008)). The technical grade substance is contaminated with 1 - 7% bis (chloromethyl) ether, which is a known human carcinogen, hence, the carcinogenicity of the substance is attributed to the contaminant (Japan Society For Occupational Health (JSOH) Recommendations for allowable concentrations (1994)).	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）
7	Reproductive toxicity	Classification not possible	- -	-	-	No data available.	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）
8	Specific target organ toxicity - Single exposure	Category 1 (respiratory organs)	Danger	H370	P308+P311 P260 P264 P270 P321 P405 P501	Based on a report that inhalation exposure to rats produced pulmonary congestion, oedema, haemorrhage and acute necrotizing bronchitis at a LD50 of 55 ppm/7h (vapour, 4-hour equivalence: 0.239 mg/L) (EHC 201 (1998)), the substance was classified into Category 1 (respiratory system). In humans, there is information that vapour exposure to 100 ppm is dangerous to life in 4-hour, and may result in pulmonary edema or pneumonia which may cause death within a few days or a week after exposure (HSDB (2005)).	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）
9	Specific target organ toxicity - Repeated exposure	Classification not possible	- -	-	-	In a 30-day inhalation exposure test in male rats (vapour, duration and frequency of exposure not specified), deaths occurred at 3.3 mg/L and higher concentrations and regenerative hyperplasia and squamous metaplasia in bronchial epithelium were observed (EHC 201 (1998)). However, the results were not used as the basis of classification since duration and frequency of exposure were not specified and data for unexposed controls was not presented. In humans, there is a report that the substance may produce chronic bronchitis with long-term inhalation (HSDB (2005)).	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）
10	Aspiration hazard	Classification not possible	- -	-	-	No data available.	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）
