CHEMICAL DANGERS:


OCCUPATIONAL EXPOSURE LIMITS:
TLV: (as Fluoride) 2.5 mg/m as TWA; A4 (not classifiable as a human carcinogen); BEI issued; (ACGIH 2005).
MAK: (as Fluoride) (Inhalable fraction) 1 mg/m;
Peak limitation category: II(4);
skin absorption (H);
Pregnancy risk group: C;
(DFG 2005).
OSHA PEL*: TWA 2.5 mg/m3 *Note: The PEL also applies to other inorganic, solid fluorides (as F).
NIOSH REL*: TWA 2.5 mg/m3 *Note: The REL also applies to other inorganic, solid fluorides (as F).
NIOSH IDLH: 250 mg/m3 (as F) See: fluoride


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 SHORT-TERM EXPOSURE:


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.
