A colorless or slightly yellow colored liquid with a strong sulfur odor. Calcium dithionite is corrosive to skin and eyes and may be toxic by ingestion or inhalation.
Air & Water Reactions
Flammable/combustible material. May ignite on contact with air or moist air.
Reactivity Profile
Reacts with oxidizing agents to generate heat and products that may be flammable, combustible, or otherwise reactive. These reactions may be violent. Sulfites generate gaseous sulfur dioxide in contact with oxidizing acids and nonoxidizing acids. Noncombustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes.
Health Hazard
Fire will produce irritating, corrosive and/or toxic gases. Inhalation of decomposition products may cause severe injury or death. Contact with substance may cause severe burns to skin and eyes. Runoff from fire control may cause pollution.
Fire Hazard
Flammable/combustible material. May ignite on contact with moist air or moisture. May burn rapidly with flare-burning effect. Some react vigorously or explosively on contact with water. Some may decompose explosively when heated or involved in a fire. May re-ignite after fire is extinguished. Runoff may create fire or explosion hazard. Containers may explode when heated.
