The NFPA provides recommendations in codes 45 and 30 for the quantities of materials that should be stored in labs in and out of these cabinets.

There is no federal requirement for these cabinets to be vented.

Assign a staff member to be responsible for oversight of the cabinet. This responsibility can include checking to make sure that containers are properly labeled, caps are tight, and the inventory on the cabinet door is up to date.
