I would think that it would not be very easy to obtain since it is a
strong
oxider, and its heat of reaction with reducing agents or combustibles may
cause
ignition. Contact with oxidizable substances may cause extremely violent
combustion (explosion).

Especially since we are so oxidizable ourselves. PP is not to be triffled
with. We've got some links about it here,
