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

STORAGE

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.
Separated from mineral acids.

ICSC: 1323 Prepared in the context of cooperation between the International Programme on Chemical Safety & the Commission of the European Communities (C) IPCS CEC 1994. No modifications to the International version have been made except to add the OSHA PELs, NIOSH RELs and NIOSH IDLH values.

PHYSICAL STATE; APPEARANCE:
COLOURLESS CRYSTALS OR WHITE HYGROSCOPIC POWDER

PHYSICAL DANGERS:


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.

EFFECTS OF SHORT-TERM EXPOSURE:


EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:

PHYSICAL
PROPERTIES

Boiling point: 2500°C
Melting point: 1403°C
Density: 3.2
g/cm3
Solubility in water: none
at 20°C
