SPILLAGE DISPOSAL
PACKAGING & LABELLING
Sweep spilled substance into containers; if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place. Personal protection: P2 filter respirator for harmful particles.
EMERGENCY RESPONSE
SAFE STORAGE
Separated from mineral acids.
IMPORTANT DATA
Physical State; Appearance COLOURLESS CRYSTALS OR WHITE HYGROSCOPIC POWDER
Chemical dangers On combustion, forms toxic fumes of fluoride. Reacts with mineral acids to produce corrosive fumes.
Occupational exposure limits TLV: (fluorides, as F) 2.5 mg/m³ as TWA; A4 (not classifiable as a human carcinogen); BEI issued; (ACGIH 2004). MAK: (as F) (Inhalable fraction) 1 mg/m³; Peak limitation category: I(4); skin absorption (H); Pregnancy risk group: C; (DFG 2005).
Routes of exposure The substance can be absorbed into the body by inhalation of its aerosol and by ingestion.
Inhalation risk Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly on spraying.

Boiling point: 2500°C Melting point: 1403°C Density: 3.2 g/cm³ Solubility in water: none at 20°C
NOTES
Calcium fluoride minerals are mined as fluorite and fluospar. Card has been partly updated in April and October 2005. See section Occupational Exposure Limits.
