Additional Information:
|
Octafluorocyclobutane is a nonflammable, colorless,
odorless liquefied compressed gas package in cylinders
under its own vapor pressure of 25 psig at 70
°F. This product can cause rapid suffocation
when concentrations are sufficient to reduce oxygen
levels below 19.5%. Self Contained Breathing Apparatus
(SCBA)may be required for rescue workers. Contact
with product can cause frostbite.
