2	Skin corrosion/irritation	Classification not possible	- -	-	-	Due to lack of data, the classification is not possible.	FY2015	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
3	Serious eye damage/eye irritation	Classification not possible	- -	-	-	The classification is not possible due to lack of data. Besides, it is written that dust of this substance may cause mild inflammation in eyes (HSDB (Access on June 2015)).	FY2015	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
4	Respiratory sensitization	Classification not possible	- -	-	-	Due to lack of data, the classification is not possible.	FY2015	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
4	Skin sensitization	Classification not possible	- -	-	-	Due to lack of data, the classification is not possible.	FY2015	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
5	Germ cell mutagenicity	Classification not possible	- -	-	-	The classification is not possible due to lack of data. There are no in vivo and in vitro data for metallic aluminum.	FY2015	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
6	Carcinogenicity	Classification not possible	- -	-	-	In 1970's, increased incidences of bladder and lung cancers were reported in workers at electrolysis tank of aluminum reduction plants. In IARC, working in the aluminum refining process is related to increased risk of cancers in workers, but it is estimated that the causative substance of cancers is not aluminum itself, but polycyclic aromatic hydrocarbon compounds, known carcinogens, or coal tar pitch volatiles, which are by-products derived from the decomposition of electrodes in the electrolysis tank. (IARC Suppl. 7 (1984), ACGIH (7th, 2008), ATSDR (2008)) As results of following epidemiological studies, some reports suggested a functional disorder of respiratory organs, or non-tumor lesions in respiratory organs by exposure to this substance, but there is no report on carcinogenicity (ACGIH (7th, 2008), ATSDR (2008)). Therefore, ACGIH classified in A4 (ACGIH (7th, 2008)). From the above, the substance was classified as "Classification not possible" in this hazard class.	FY2015	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
7	Reproductive toxicity	Classification not possible	- -	-	-	Due to no information on reproductive toxicity by exposure to this substance, the classification is not possible due to lack of data. Besides, it is reported that in a test in which aluminum chloride or aluminum lactate was dosed in an oral route to pregnant rats during a gestation period, or to neonatal rats on day 5-17 after birth, delayed neurobehavioral development or hypoactivity was observed in newborns (ACGIH (7th, 2008), ATSDR (2008)).	FY2015	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
8	Specific target organ toxicity - Single exposure	Category 1 (respiratory organs)	Danger	H370	P308+P311 P260 P264 P270 P321 P405 P501	This substance (dust, powder) is irritating to the respiratory tract (HSDB (Access on June 2015)). As for humans, inhalation of this substance (dust) could cause lung disorder such as pneumoconiosis (aluminosis) (HSDB (Access on June 2015)). As for experimental animals, it is reported that in single inhalation exposure to this substance (dust) in rats, no change in pulmonary function but enzymatic and cytological changes in bronchoalveolar lavage fluid were observed at 0.05 mg/L, and microgranuloma development occurred in the lung and hilum lymph nodes (microscopic observation) at 0.2 mg/L. These were observed at doses corresponding to Category 1 (ACGIH (7th, 2008), PATTY (6th, 2012)). From the above, because this substance has effects on the respiratory organs in inhalation exposure, it was classified in Category 1 (respiratory system). Besides, respiratory tract irritation was included in effects on the respiratory organs. By adding new information, the previous classification was revised.	FY2015	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
9	Specific target organ toxicity - Repeated exposure	Category 1 (respiratory organs)	Danger	H372	P260 P264 P270 P314 P501	As for humans, in an epidemiological survey of 1,142 workers related to manufacturing aluminum and its compounds (1975-1981), effects on lung function were observed in exposure to dust of high concentration (> 100 mg/m3-year as total dust), and in chest X-ray examination, small and irregular nodes were reported in a lower part of the lung in 7-8% (ACGIH (7th, 2008)). As for experimental animals, there is no test report using this substance. Therefore, the substance was classified in Category 1 (respiratory system). Besides, as for humans, it is written that decreased cognitive test results were observed, but the clear conclusion was not be drawn (ATSDR (2008)). Moreover, it is written that aluminum is not a factor causing Alzheimer's disease at this time, and that in many studies, there is no consistent relationship between aluminum and nervous disorder (ACGIH (7th, 2008)). Therefore, central nervous system was not included in a target organ.	FY2015	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
10	Aspiration hazard	Classification not possible	- -	-	-	Due to lack of data, the classification is not possible.	FY2015	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
