HEALTH HAZARDS

Hazard class		Classification	Symbol	Signal word	Hazard statement	Precautionary statement	Rationale for the classification
1	Acute toxicity （Oral）	Not classified	-	-	-	-	Based on the statement of indium oxide LD50> 10g/kg (SAX (4th, 2001)) and tin oxide LD50> 6.6g/kg (RTECS (2004)), it was set as the outside of Category. Since an indium tin oxide is considered to be a mixture of an indium oxide and a tin oxide, LD50 value as a mixture should be calculated according to the definition of GHS. But LD50 value of both compounds is 5g/kg or more, it becomes the outside of Category.
1	Acute toxicity （Dermal）	Classification not possible	-	-	-	-	No data available
1	Acute toxicity （Inhalation: Gases）	Not applicable	-	-	-	-	Solid (GHS definition)
1	Acute toxicity （Inhalation: Vapours）	Classification not possible	-	-	-	-	No data available
1	Acute toxicity （Inhalation: Dusts and mists）	Classification not possible	-	-	-	-	No data available
2	Skin corrosion/irritation	Classification not possible	-	-	-	-	No data available
3	Serious eye damage/eye irritation	Classification not possible	-	-	-	-	No data available
4	Respiratory sensitization	Classification not possible	-	-	-	-	No data available
4	Skin sensitization	Classification not possible	-	-	-	-	No data available
5	Germ cell mutagenicity	Classification not possible	-	-	-	-	No data available
6	Carcinogenicity	Classification not possible	-	-	-	-	No data available
7	Reproductive toxicity	Classification not possible	-	-	-	-	No data available
8	Specific target organ toxicity - Single exposure	Classification not possible	-	-	-	-	No data available.
9	Specific target organ toxicity - Repeated exposure	Category 1 (lung, skeletal system, gastrointestinal tract)		Danger	H372: Cause damage to organs through prolonged or repeated exposure (lung, skeletal system, gastrointestinal tract)	P260: Do not breathe dust/fume/gas/mist/vapours/spray. P264: Wash ... thoroughly after handling. P270: Do not eat, drink or smoke when using this product. P314: Get medical advice/attention if you feel unwell. P501: Dispose of contents/container to ...	"For indium and its compound, TLV-TWA is set up by the influence to skelton and gastrointestinal system and the hazardous property especially by the inhalation to lungs (ACGIH (7h, 2001))" "There is a case report of the pulmornary fibrosis by the indium tin oxide of two examples in humans (J Occup Health 45:137-139 (2003)), (Eur Respr J.25(1):201-204 (2005)", "An indium tin oxide consists of indium oxides and tinoxide (J Occup Health (2002))"and "Since an indium tin oxide contain high idium content (indium 74% and tin 8%), major cause of the observed lung toxicity is probably indium. (Eur Respr J.25(1):201-204 (2005))" -based on these, it was classified to as Category 1 (lungs, skeletal, digestive tracts). [special notes] Since indium was recorded and selected as indium and its compound also by ACGIH and industrial safety and health laws, idium tin oxide was evaluated and classified as the indium analogue.
10	Aspiration hazard	Classification not possible	-	-	-	-	No data available
