  Work in an inert atmosphere in a glove box, or some other way to exclude air
  A fire extinguisher should be in the work area
  PPE as required by hazard certification
     
Possible Health Effects:

  May cause thermal and chemical burns on contact with skin
  May ignite producing toxic smoke
     
First Aid:
