Important Data
|
Physical State; Appearance:
COLOURLESS LIQUID
Physical Dangers:
The vapour is heavier than air
and may accumulate in lowered spaces causing a deficiency of oxygen.
Chemical Dangers:
On contact with hot surfaces or flames this substance decomposes forming corrosive gases such as hydrogen fluoride.
Occupational Exposure Limits:
TLV not established.
|
Routes of Exposure:
The substance can be absorbed into the body
by inhalation of its vapour
and
by ingestion.
Inhalation Risk:
A harmful contamination of the air can be reached very quickly on evaporation of this substance at 20°C.
Effects of Short-Term Exposure:
The substance
is irritating to
the eyes
and
the skin
.
The vapour
is irritating to
the respiratory tract
.
The substance may cause effects on the
central nervous system
and
cardiovascular system
.
Exposure at high levels may result in unconsciousness.
Effects of Long-Term or Repeated Exposure:
|
|
Physical
Properties
|
Boiling point: 23.5 °C
Relative density (water = 1): 1.5
Solubility in water: poor
|
Vapour pressure, kPa at 20°C: 89
Relative density of the vapour/air-mixture at 20°C (air = 1): 1.4

Environmental
Data
|
|
|
N O T E S
|
|
Suprane is a trade name.
Check oxygen content before entering area.
High concentrations in the air cause a deficiency of oxygen with the risk of unconsciousness or death.
