Type of SOP: Process Hazardous Chemical Hazardous Class
Purpose
Vanadium Pentoxide (V2O5) is a highly acute toxin, suspect carcinogen, teratogen and a suspect reproductive toxin. It is a poisonous brown/yellow solid which, because of its high oxidation state, is both an amphoteric oxide and an oxidizing agent. Additional safety protocols must be in place to work Vanadium Pentoxide. This SOP helps to safely store, handle and dispose of Vanadium Pentoxide in the lab.
Use: V₂O₅ catalyzes several useful aerobic oxidation reactions, the largest scale of which underpins the production of sulfuric acid from sulfur dioxide.

  There is potential for harmful exposure due to an atmospheric contaminant (in the absence of PEL)
  
• 
  As PPE in the event of a chemical spill clean-up process
  

Lab personnel intending to use/wear a respirator mask must be training and fit-tested by EH&S. This is a regulatory requirement. (http://map.ais.ucla.edu/go/1004655)

Eye protection

Safety goggles.

Skin and body protection

• 
  Lab coat (full sleeves)
  
• 
  Full length pants
