We will be working with Picric acid in a chemical fume hood.  The airfoil part of the hood is made of stainless steel.  Picric acid reacts with many metals like lead, zinc and copper to form dangerous picrate salts.  To be safe, I was thinking of covering the steel airfoil part of the hood with aluminum foil just in case picric acid reacts with steel.  I read in some places that picric acid does not react with aluminum foil.  Does anyone know if picric acid reacts with aluminum foil?
