Magnesium fluosilicate Safety Profile

Moderately toxic by ingestion. When heated to decomposition it emits toxic vapors of magnesium and F−.
Hazard Codes:
T: Toxic
Risk Statements:
R25 Toxic if swallowed.
Safety Statements:
S45 In case of accident or if you feel unwell, seek medical advice immediately (show the label whenever possible.)
S24/25: Avoid contact with skin and eyes.
Attention:
