An aqueous solution of magnesium hydrogen sulfite. Corrosive.
MAGNESIUM BISULFITE generates gaseous toxic sulfur dioxide in contact with oxidizing acids and nonoxidizing acids. Reacts with oxidizing agents to generate heat and products that may be flammable, combustible, or otherwise reactive. Can react explosively with strong oxidizing agents.
TOXIC; inhalation, ingestion or skin contact with material may cause severe injury or death. Contact with molten substance may cause severe burns to skin and eyes. 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. Some are oxidizers and may ignite combustibles (wood, paper, oil, clothing, etc.). Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated.
