6	Carcinogenicity	Classification not possible	- -	-	-	No data available.	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）
7	Reproductive toxicity	Classification not possible	- -	-	-	In a gestation period exposure test (Teratogenic (12th, 2007)), cardiac malformations such as transportation or ventricular outflow stenosis occurred in 23% of offsprings (6.8% in controls) following exposure to rats during a single gestational day. Defects of vertebral column occurred in 16/17 fetuses (1/30 in control) following exposure to rabbits between 7th and 12th day of gestation. Additionally, there is a report that ectrodactyly was observed in mice. However, these results are insufficient for classification since exposure concentrations were too high and there is no data for fertility. Classification was not possible due to lack of data.	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）
8	Specific target organ toxicity - Single exposure	Category 3 (Narcotic effects)	Warning	H336	P304+P340 P403+P233 P261 P271 P312 P405 P501	Based on reports for human effects that carbon dioxide, when inhaled at elevated concentrations, may act to produce mild narcotic effects, and stimulation of the respiratory center (ACGIH (2001)), the substance was classified into Category 3 (narcotic effects). Case reports for two men who suddenly became unconscious from excessive carbon dioxide exposure are available. The reports indicate that repeated eye examinations showed constriction of visual fields, enlargement of blindspots, and photophobia. Headache, insomnia, and personality changes were also reported (HSDB (2008)). These symptoms were attributed to damage to retinal ganglion cells and central nervous system. Additionally, it is reported that exposure at 11% carbon dioxide can cause dysregulation and unconsciousness within 10 min, and exposure at 25 - 30 % can cause respiratory arrest, fall in blood pressure, loss of coma reflex, loss of sensation and death within a few hour (Japanese journal of industrial health vol. 15 No.3 (1974)).	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）
9	Specific target organ toxicity - Repeated exposure	Classification not possible	- -	-	-	In human exposure tests at 1.5% for a period of 42 days during exercise, mild evidence of stress reactions was apparent, but there were no measurable decrease in basic physiological functions or in psychomotor performance (ACGIH (2001)). In a test where submarine volunteers were exposed at 1% carbon dioxide for 22 days, only metabolic stress was indicated (ACGIH (2001)). Additionally, it is reported that deepened respiration was reported at 2%, respiratory resistance increased with elevation of carbon dioxide concentration and concentrations in excess of 3% was not well tolerated (ACGIH (2001)). Exposures at 3% in World War II submarines initially led to brief periods of excitation, followed by progressive depression, and subsequently cutaneous blood flow increased, core body temperature fell, blood pressure fell, and the rate of blood flow increased. Other indices of circulatory function were depressed, the rate of breathing was slowed, and mental functions were impaired (PATTY (5th, 2001)). Additionally, there is a report that acidosis and adrenal cortical exhaustion occur as the result of prolonged, continuous exposure to an atmosphere containing 1 to 2% carbon dioxide (ACGIH (2001)). The available information in respect to repeat exposure is limited and most of the data is obsolete. The findings lack consistency except for slight effects, therefore classification was not possible due to lack of data.	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）

GHS Classification Result by the Japanese Government is intended to provide a reference for preparing a GHS label or SDS for users. To include the same classification result in a label or SDS for Japan is NOT mandatory.
Users can cite or copy this classification result when preparing a GHS label or SDS. Please be aware, however, that the responsibility for a label or SDS prepared by citing or copying this classification result lies with users.
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”. If no English translation is available for “Rationale for the classification,” please refer to the Japanese version of the results.
