| Additional
Information: |
Trifluoromethane is a nonflammable,
colorless, odorless liquefied compressed gas packaged
in cylinders under its own vapor pressure of 611psig
at 70°F. It 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. |
