Thank you for the information and insightful comments. My company is small and there is little support even for issues which seem relatively clear to me. Also, as coordinator, my position is advisory only so my opinions tend to be creatively interpreted unless department managers and upper management actively enforce the regulations within their groups.

The BMBL-5 under B 10 Special Practices states "All procedures involving the manipulation of infectious materials that may generate an aerosol should be conducted within a BSC or other physical containment devices."
But as we know, spills and other unexpected things can happen - even in a BSL-2 area - despite our best efforts to keep the micro-organisms contained. That's why, e.g., the microbiologists working with rabies have all the recommended immunizations as well as ppe, even though the work is done in biosafety cabinets. Sawing through an animal skull to retrieve a brain tissue specimen will definitely produce aerosols. [BTW, not only is there an aerosol risk, but saws and scalpels are sharp tools.]
Plus there's the possibility that someone's forgotten moldy lunch could cross-contaminate lab work. BMBL-5 under B 9 Special Practices states "Animal and plants not associated with the work being performed must not be permitted in the laboratory."
Stay with the program. Don't try to justify relaxing the industry standard because some employees find certain laboratory policies inconvenient. Would we be having this same discussion about BSL-3 (or 4?!) containment practices?
Bottom line ==> Keep food, animals, and plants out from within the high solid walls of the lab area.
