| Additional
Information: |
Tetrafluoromethane is a nonflammable,
colorless, odorless compressed gas packaged in cylinders
at pressures up to 2000 psig. 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. |
