Additional Information:
|
Ethane is a flammable, odorless liquefied compressed
gas packaged in cylinders under its own vapor
pressure of 559.6 psia at 70 °F. It poses
an immediate fire and explosion hazard when mixed
with air at concentrations exceeding 3.0%. Ethane
is heavier than air and may travel a considerable
distance to an ignition source. High concentrations
that can cause rapid suffocation are above the
lower flammable limit and should not be entered.
It is generally odorless at concentrations below
2.0%. Direct contact with liquid can cause frostbite.
