Important Data
|
Physical State; Appearance:
COLOURLESS
COMPRESSED GAS
, WITH PUNGENT ODOUR.
FORMS WHITE FUMES IN MOIST AIR.
Physical Dangers:
The gas is heavier than air.
Chemical Dangers:
The substance will polymerize unsaturated compounds.
The substance decomposes
on contact with
water
and
moisture
producing toxic and corrosive fumes including hydrogen fluoride (see ICSC0283), fluoroboric acid and boric acid.
Reacts violently with metals such as sodium, potassium and calcium, and with alkyl nitrates.
Attacks many metals in presence of water.
Occupational Exposure Limits:
TLV: 1 ppm (Ceiling value); (ACGIH 2004).
MAK: IIb (not established but data is available) (DFG 2004).
OSHA PEL: C 1 ppm (3 mg/m3)
NIOSH REL: C 1 ppm (3 mg/m3)
NIOSH IDLH: 25 ppm See: 7637072
|
Routes of Exposure:
The substance can be absorbed into the body
by inhalation.
Inhalation Risk:
A harmful concentration of this gas in the air will be reached very quickly on loss of containment.
Effects of Short-Term Exposure:
Corrosive.
Lachrymation.
The substance
is corrosive to
the eyes,
the skin
and
the respiratory tract.
Inhalation of the gas may cause lung oedema (see Notes).
Rapid evaporation of the liquid may cause frostbite.
Effects of Long-Term or Repeated Exposure:
The substance may have effects on the kidneys.

N O T E S
|
Boron trifluoride is soluble in cold water, 332 g/100 ml at 0°C.
The occupational exposure limit value should not be exceeded during any part of the working exposure.
Depending on the degree of exposure, periodic medical examination is suggested.
The symptoms of lung oedema 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.
Immediate administration of an appropriate inhalation therapy by a doctor or a person authorized by him/her, should be considered.
Card has been partly updated in April 2005. See sections Occupational Exposure Limits, EU classification, Emergency Response.
