Additional Information:
|
Sulfur Hexafluoride is a nonflammable, liquefied
compressed gas packaged in cylinders under its
own vapor pressure of 298 psig at 70°F. It
can cause rapid suffocation when concentrations
are sufficient to reduce oxygen levels below 19.5%.
Contact with liquid may cause frostbite. Avoid
breathing gas. Self contained breathing apparatus
(SCBA) may be required by rescue works.
