Physical State; Appearance:
HYGROSCOPIC
,
WHITE
OR
COLOURLESS
CRYSTALS
Physical Dangers:
Chemical Dangers:
The substance decomposes
on heating
producing toxic fumes of fluorine.
Occupational Exposure Limits:
TLV: (fluorides, as F) 2.5 mg/m3 as TWA; A4 (not classifiable as a human carcinogen); BEI issued; (ACGIH 2004). TLV: (as Al) 2 mg/m3 as TWA; (ACGIH 2004).
MAK: (as F) (Inhalable fraction) 1 mg/m3
Peak limitation category: I(4);
skin absorption (H);
Pregnancy risk group: C;
(DFG 2005).
EU OEL: (fluorides as F) 2.5 mg/m3 (EU 2004).
|
Routes of Exposure:
The substance can be absorbed into the body
by inhalation of the dust
and
by ingestion.
Inhalation Risk:
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly.
Effects of Short-Term Exposure:
The aerosol
is irritating to
the eyes
,
the skin
and
the respiratory tract
.
Effects of Long-Term or Repeated Exposure:
Repeated or prolonged inhalation exposure may cause asthma.
The substance may have effects on the bone,
nervous system
, resulting in bone alterations (fluorosis), and nervous system impairment.

CAS 15098-87-0 and 32287-65-3 are for hydrated forms.
Temperature of decomposition unknown in literature.
The symptoms of asthma often do not become manifest until a few hours have passed and they are aggravated by physical effort. Rest and medical observation are therefore essential.
Anyone who has shown symptoms of asthma due to this substance should avoid all further contact with this substance.
Card has been partly updated in April and October 2005. See sections Occupational Exposure Limits, Emergency Response.
