Subject: precautions for oxygen combustion for fluorine analysis?

I have been asked to investigate whether we might do fluorine analysis of our fabric samples.  As I understand it, the procedure requires oxygen combustion in a Schoniger flask.  I am concerned about the safety of the procedure for  technicians who generally do not perform hazardous tests and do not work with oxygen.  Is anyone familiar with this and could give me some idea of what types of safety precautions/equipment is necessary?  For instance, is this usually done in an ordinary chemical hood? What about face shields?

Thank you for your assistance.
