Sodium aluminosilicate also goes by the names aluminosilicic acid, sodium salt, aluminum sodium silicate, sasil, silicic acid and aluminum sodium salt. It is used as a food additive to prevent caking or clumping in dry powdered mixtures. It is also added to latex paint to create a flat finish and is a component of household cleaning products. Although it is generally safe in these products, handling the raw chemical material may be dangerous.
Hazards
Sodium aluminosilicate may enter the body through the respiratory system or by ingestion and cause serious health consequence. In the case of a severe exposure, it may cause death. Sodium aluminosilicate is highly toxic by inhalation. The particles may cause irritation to the eyes, respiratory tract and mucous membranes. If it contacts the skin, it will cause skin irritation. Sodium aluminosilicate is also toxic by ingestion.
First Aid
Seek medical attention for any type of acute exposure to pure sodium aluminosilicate. In case of eye contact, remove contact lenses and flush the eyes with water for 15 minutes. Skin contact should be treated by flushing with water and then covering the affected area with an emollient. In the case of inhalation, move to fresh air and provide artificial respiration if the victim is not breathing. Oxygen may be required. For exposures through ingestion, do not induce vomiting unless directed to do so by medical personnel. Loosen tight clothing but do not give anything by mouth.
Protection
In order to work safely with pure sodium aluminosilicate, you need to have the correct protective equipment. Use safety goggles to protect your eyes from contact. Choose gloves that are impervious to the material. Depending on the amounts you using, a laboratory apron or splash guard may be necessary.
Prevention
Keep sodium aluminosilicate locked up and stored away from children to prevent accidental exposures. Consult a chemical safety specialist before you begin working with the material. Become knowledgeable about available fume hoods, exhaust ventilation or other engineering controls to minimize the levels of airborne particles. If your work area does not provide sufficient ventilation, you will need to obtain and wear respiratory equipment.
