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

SPILLAGE DISPOSAL	PACKAGING & LABELLING
Personal protection: P2 filter respirator for harmful particles. Sweep spilled substance into covered containers; if appropriate, moisten first to prevent dusting.

Occupational exposure limits
TLV: (as Fluoride) 2.5 mg/m³ as TWA; A4 (not classifiable as a human carcinogen); BEI issued; (ACGIH 2005).
MAK: (as Fluoride) (Inhalable fraction) 1 mg/m³; Peak limitation category: II(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
A harmful concentration of airborne particles can be reached quickly when dispersed, especially if powdered.

Effects of long-term or repeated exposure
The substance may have effects on the bones and teeth, resulting in fluorosis. Lungs may be affected by repeated or prolonged exposure to dust particles.
