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 1	Danger	H300	P301+P310 P264 P270 P321 P330 P405 P501	From an LD50 value of 2 mg/kg bw for rats (HSDB (2007)), it was classified in Category 1.	FY2011	GHS Classification Guidance by the Japanese Government （July, 2010）
1	Acute toxicity (Dermal)	Classification not possible	- -	-	-	Lack of data. Besides, even in original literature, details of a reported LD50 value of 24 mg/kg bw for rats (GESTIS (Access on Dec. 2011)) from List 3 are unknown.	FY2011	GHS Classification Guidance by the Japanese Government （July, 2010）
1	Acute toxicity (Inhalation: Gases)	Not classified (Not applicable)	- -	-	-	It is a liquid at normal temperatures (GESTIS (Access on Dec. 2011)).	FY2011	GHS Classification Guidance by the Japanese Government （July, 2010）

Besides, a reference value of gasses as a vapour with hardly included mist was applied because the LC50 value (1 ppm) is lower than 90 % of the saturated vapour pressure concentration (14342 ppm).	FY2011	GHS Classification Guidance by the Japanese Government （July, 2010）
1	Acute toxicity (Inhalation: Dusts and mists)	Classification not possible	- -	-	-	No data.	FY2011	GHS Classification Guidance by the Japanese Government （July, 2010）
2	Skin corrosion/irritation	Category 1	Danger	H314	P301+P330+P331 P303+P361+P353 P305+P351+P338 P304+P340 P260 P264 P280 P310 P321 P363 P405 P501	From the information that it is extremely destructive to tissues of skin (HSDB (2007)), it was classified in Category 1.	FY2011	GHS Classification Guidance by the Japanese Government （July, 2010）

8	Specific target organ toxicity - Single exposure	Category 1 (nervous system, respiratory organs)	Danger	H370	P308+P311 P260 P264 P270 P321 P405 P501	This substance is known as an acetylcholinesterase inhibitor and a potent methylating agent (HSDB (2007)). Extremely toxic as an LC50 value (vapour) of 1.0 to 1.2 ppm (converted to a 4-hour equivalent: 0.0053 to 0.0064 mg/L) for rats in a 7-hour inhalation exposure (vapour) and the main symptoms caused by the acetylcholinesterase inhibition before deaths were reported. (RTECS (2009): original literature American Industrial Hygiene Association Journal (1979)) The information that inhalation in humans may be fatal as a result of spasm, inflammation and edema of the larynx and bronchi, chemical pneumonitis, and pulmonary edema (HSDB (2007)) indicates effects on the respiratory system as a methylating agent. The above information from List 2 corresponds to Category 2, but it was classified in Category 1 (nervous system, respiratory system) by the expert judgment.	FY2011	GHS Classification Guidance by the Japanese Government （July, 2010）
9	Specific target organ toxicity - Repeated exposure	Category 1 (nervous system)	Danger	H372	P260 P264 P270 P314 P501	Severe clinical signs by exposure of this substance known as an acetylcholinesterase inhibitor and a potent methylating agent to humans include muscle fasciculation, weakness, respiratory failure, central nervous system depression, confusion, delirium, and coma (HSDB (2007)). The above information from List 2 corresponds to Category 2, but it was classified in Category 1 (nervous system) by the expert judgment. Besides, as animal tests, 3-month inhalation exposure (vapour) to rats at low concentrations of 20 or 100 ppb (seven hours/day, five days/week) reported no adverse effects except significantly decreased cholinesterase in red blood cell and brain at 100 ppb (RTECS (2009): original literature American Industrial Hygiene Association Journal (1979)).

This GHS classification was conducted based on the information sources and the guidance for classification and judgement which are described in the GHS Classification Guidance for the Japanese Government etc. Using other literature, test results etc. as evidence and including different content from this classification result in a label or SDS are allowed.
Hazard statement and precautionary statement will show by hovering the mouse cursor over a code in the column of "Hazard statement" and "Precautionary statement," respectively. In the excel file, both the codes and statements are provided.
A blank or "-" in the column of "Classification" denotes that a classification for the hazard class was not conducted in the year.
An asterisk “*” in the column of “Classification” denotes that “Not classified (or No applicable)” and/or “Classification not possible” is applicable. Details are described in the column of “Rationale for the classification”.
