CLASSIFICATION & LABELLING
Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Sweep spilled substance into covered containers. If appropriate, moisten first to prevent dusting. Carefully collect remainder. Then store and dispose of according to local regulations.
According to UN GHS Criteria
Transportation UN Classification
Separated from mineral acids.
PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance COLOURLESS CRYSTALS OR WHITE HYGROSCOPIC POWDER.
Physical dangers No data.
Chemical dangers On combustion, forms toxic fumes of fluoride. Reacts with mineral acids. This produces corrosive fumes.
Molecular mass: 78.1
Boiling point: 2500°C Melting point: 1403°C Density: 3.2 g/cm³ Solubility in water at 20°C: none
EXPOSURE & HEALTH EFFECTS
Routes of exposure The substance can be absorbed into the body by inhalation of its aerosol and by ingestion.
Effects of short-term exposure
Inhalation risk Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly on spraying.
Effects of long-term or repeated exposure
