Introduction of Sodium fluorosilicate
General Description:Fine, white, odorless, powdered solid. Toxic by ingestion, inhalation and skin absorption. Used as a rodenticide.
CAS Number:16893-85-9
UN/NA Number:2674
DOT Hazard Label:Poison
Synonyms: Sodium hexafluorosilicate, Sodium fluorosilicate, Sodium fluosilicate ,SODIUM SILICOFLUORIDE
Air & Water Reactions:Water soluble.
Fire Hazard:Behavior in Fire: Decomposes at red heat (USCG, 1999)
Health Hazard:Inhalation of dust may irritate nose and throat. Ingestion causes symptoms similar to fluoride poisoning; compound is highly toxic; initial symptoms include nausea, cramps, vomiting, diarrhea, and dehydration; in severe cases, convulsions, shock, and cyanosis are followed by death in 2-4 hr. Contact with eyes causes irritation. Contact with skin causes rash, redness, and burning, sometimes followed by ulcer formation. (USCG, 1999)
Reactivity Profile:SODIUM FLUOROSILICATE has weak oxidizing or reducing powers. Redox reactions can however still occur. The majority of compounds in this class are slightly soluble or insoluble in water. If soluble in water, then the solutions are usually neither strongly acidic nor strongly basic. These compounds are not water-reactive.
Solutions of sodium fluorosilicate may contain some hydrofluoric acid, which can cause severe chemical burns and is one of the few materials that can etch glass. Unlike other halide ions, fluoride is quite reactive, acting as a weak base and participating in some unique reactions. In particular, fluorides react strongly with compounds containing calcium, magnesium, or silicon ions, which means that solutions containing soluble fluorides are corrosive to both living tissue and glass.
Protective Clothing
Dust respirator; goggles or face shield; protective gloves (USCG, 1999)
First Aid
INHALATION: move to fresh air.
INGESTION: seek medical attention; administer gastric lavage with lime water, then give lime water or milk at frequent intervals.
EYES: flush with water for at least 15 min.
SKIN: flush with water; wash with soap and water. (USCG, 1999)
