Trimagnesium diarsorate (CAS.NO 10103-50-1) is a white crystals or powder when pure and insoluble in water.It is very toxic by inhalation and ingestion and used as an insecticide. It may be fatal if inhaled, swallowed or absorbed through skin. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.
Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Containers may explode when heated. Runoff may pollute waterways.
