Additional Information:
|
Butane is a flammable, colorless liquefied compressed
gas packaged in cylinders under its own vapor
pressure of 31.3 psia at 70 °F. It poses an
immediate fire and explosion hazard when mixed
with air at concentrations exceeding 1.8%. High
concentrations that can cause rapid suffocation
are above the lower flammable limit and must not
be entered. Butane is heavier than air and may
collect in low areas or travel along the ground
where there may be an ignition source present.
Pure butane in odorless, however, in some cases
an additional odorant may have been added. Direct
contact with liquid can cause frostbite.
