Description of key information

This substance is void of any chemical structures commonly associated with explosive properties, such as metal peroxides, peroxo-acid-anions, azides, and halogen oxides.  A test for thermal-stability (OECD 113) has shown that gallium arsenide shows no endo- or exothermic reaction upon heating up to at least 600°C. Gallium arsenide is also not flammable (Test according to EU method A.10). Further, it is noted that despite long-term industrial use of the substance, it is not classified for explosive properties according to UN transport regulations. In consequence, GaAs is not considered to be explosive.
