4.8 Specification

1.Health Hazard: Potassium metavanadate (CAS NO.13769-43-2) is highly toxic, may be fatal if inhaled, swallowed or absorbed through skin.When it is used,please 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.
2.Fire Hazard :Non-combustible, Potassium metavanadate (CAS NO.13769-43-2) 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.
