If none of the hoods are now being used to ventilate activities or processes that require local ventilation, and if the occupancy of the building has been drastically reduced or eliminated because of the current epidemic, I see no reason that the hoods could not be shut off as long as there is adequate residual ventilation being provided by other systems for any people who continue to occupy the building.

=E2=80=8BI've received the following from a colleague at another school.
The powers that be want to save money by shutting down the hoods in our building. That doesn't seem like a good idea to me and I have asked others and they agree, but no one can tell me why we shouldn't shut them down. Do you have any insights on this? Should I be concerned if all the hoods get shut down? If so, why?=E2=80=8B
I agree with the department, not the PTB, but would like more feedback
