TYPES OF HAZARD / EXPOSURE ACUTE HAZARDS / SYMPTOMS PREVENTION FIRST AID / FIRE FIGHTING
FIRE Not combustible.

In case of fire in the surroundings: use appropriate extinguishing media.
EXPLOSION


EXPOSURE
PREVENT DISPERSION OF DUST!

Inhalation
Ventilation (not if powder), local exhaust, or breathing protection.
Fresh air, rest.
Skin
Protective gloves.
Rinse and then wash skin with water and soap.
Eyes
Safety spectacles.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
Ingestion Nausea. Vomiting.
Do not eat, drink, or smoke during work.
Rinse mouth.
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.

CALCIUM FLUORIDE ICSC: 1323
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/m as TWA; A4 (not classifiable as a human carcinogen); BEI issued; (ACGIH 2004).
MAK: (as F) (Inhalable fraction) 1 mg/m; 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 20C is negligible; a harmful concentration of airborne particles can, however, be reached quickly on spraying.

PHYSICAL PROPERTIES
Boiling point: 2500C
Melting point: 1403C
Density: 3.2 g/cm
Solubility in water: none at 20C
ENVIRONMENTAL DATA

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.
