For science labs that have room exhaust fans, how are they considered in the context of background noise? Are they excluded because of infrequent use, or are they typically required to be included? Same question for rooms with hoods in the lab. Thanks.

The language used in the background noise requirements is "HVAC systems" but we've taken that to mean the "always running in the background HVAC systems".
If there's a switch the instructor can use to turn the fans on when needed, we're assuming that they can always turn it off if they need it to be more quiet for instruction.
