I am curious as to what your design standards are for new lab installs with UNDER HOOD flammable storage cabinets. Manufacturers sell vent kits for these to vent behind the baffles into the hood and, back in my researcher days, most labs I worked in had under hood cabinets ventilated. NFPA advises against venting any flammable cabinets and I am getting mixed messages from various vendors and lab design teams.  I have read a number of other university design standards and they are also inconsistent.

What do your universities do?  I usually recommend against venting standalone flammable storage but I am a bit torn on the under hood storage cabinets.
