Additional Information:
|
Propane is a flammable, odorless, colorless
liquefied compressed gas packaged in cylinders
under its own vapor pressure of 124.9 psia at
70 °F. It poses an immediate fire and explosion
hazard when mixed with air at concentrations exceeding
2.1%. High concentrations that can cause rapid
suffocation are above the lower flammable limit
and must not be entered. Propane is heavier than
air and may collect in low areas or travel along
the ground where there may be an ignition source
present. Direct contact with liquid can cause
frostbite.
