SECTION 2: Hazards identification

Emergency Overview Magnesium Sulfate Heptahydrate is an odorless, colorless to white solid in crystalline form. Contact may cause irritation to eye, skin, and respiratory system. Magnesium Sulfate Heptahydrate is not flammable or reactive. Thermal decomposition of Magnesium Sulfate Heptahydrate produces irritating vapors and toxic gases (e.g. sulfur oxides). Emergency responders should wear proper personal protective equipment for the releases to which they are responding.

Hazard statements

Caution! May cause irritation to eyes, skin, and respiratory system. Avoid contact with eyes and prolonged contact with skin. Avoid breathing dusts. Wash thoroughly after handling. Keep container closed. Use with adequate ventilation.

Potential health effects

Eyes Exposure to particulates or solution of Magnesium Sulfate Heptahydrate may cause mild irritation of the eyes with symptoms such as stinging, tearing and redness. Skin Magnesium Sulfate Heptahydrate can cause slight irritation of the skin, especially after prolonged exposures. Repeated skin contact may lead to dermatitis (red, cracked skin). Symptoms are generally alleviated when exposure ends. Ingestion Ingestion of Magnesium Sulfate Heptahydrate(especially in large volumes) can cause symptoms which include vomiting, diarrhea, and nausea. If elimination is blocked by bowel blockage or other reasons, depression of the central nervous system, lack of reflexes and hypocalcemia can occur. Inhalation Breathing dusts or particulates generated by Magnesium Sulfate Heptahydrate can lead to irritation of the nose, throat or respiratory system. Symptoms of such exposure could include coughing and sneezing. Symptoms are generally alleviated when exposure ends.
