-
- - It is non-flammable (HSFS (2010)).
12 Substances and mixtures which, in contact with water, emit flammable gases Not classified
-
-
- - It is estimated that it does not react vigorously with water because there is the observation result of insoluble in water (HSFS (2010)).
13 Oxidizing liquids Not applicable
-
-
- - "Solids" according to GHS definition.
14 Oxidizing solids Classification not possible
-
-
- - It is an inorganic compound that contains oxygen, but the classification is not possible due to no data.
15 Organic peroxides Not applicable
-
-
- - It is an inorganic compound.

There is no information on human carcinogenicity of this substance itself. However, because this substance belongs to crystalline silica (IARC 100C (2012), CICAD 24 (2000)), it is estimated to have carcinogenicity equivalent to that of crystalline silica. Therefore, this substance was classified in Category 1A in this hazard class.
Besides, it is written that while a dosed group in a single intrapleural injection of this substance 20 mg/body and observation for a life span in rats had an average survival of 525 days and showed malignant lymphomas of a histiocytic type in 16 (16/32), a control group had an average survival of 717 days and did not show tumors of the such type (0/32) (IARC 68 (1997), ACGIH (7th, 2006)).
7 Reproductive toxicity Classification not possible
-
-
- - Due to lack of data, the classification is not possible.
8 Specific target organ toxicity - Single exposure Classification not possible
-
-
- - Due to lack of data, the classification is not possible.
9 Specific target organ toxicity - Repeated exposure Category 1 (respiratory organs)


Danger
H372 P260
P264
P270
P314
P501
Data for humans were not obtained. Data on repeated dose toxicity in experimental animals were not obtained.
However, it is thought that this substance which is the same crystalline silica as quartz has the similar effects on respiratory organs as quartz. Therefore, this substance was classified in Category 1 (respiratory organs).
10 Aspiration hazard Classification not possible
-
-
- - Due to lack of data, the classification is not possible.

NOTE:
* A blank or "-" in a cell of classification denotes that the classification of the hazard class was not conducted.
* Hazard_statement_and/or_Precautionary_statement will show when hovering the mouse over a code of Hazard_statement_and/or_Precautionary_statement.
Hazard_statement_and/or_Precautionary_statement are also provided in the Excel file.
* Classification was conducted by relevant Japanese Ministries in accordance with GHS Classification Guidance for the Japanese Government,
and is intended to provide a reference for preparing GHS labelling and SDS for users.
* This is a provisional English translation of classification results and is subject to revision without notice.
* The responsibility for any resulting GHS labelling and SDS referenced from this site is with users.
* Codes assigned to each of the hazard statements and codes for each of the precautionary statement are
based on the Globally Harmonized System of Classification and Labelling of Chemicals (GHS) in United Nations.
