If concentrations could reach explosive levels (spills etc.) surely they could be drawn into the srtucture as well.
That is one of the problems I've had with garage installations of AHU.
The other is energy efficiency (related to both the unconditioned space being around the unit and related to that unconditioned and contaminated air being drawn into the AHU).
Same applies to AHU in attics.
