The potential to accelerate the offgassing but not adequately ventilate and
get the stuff pushed out of the building. So now you¹ve made the fishbowl a
little more...fishbowl. Too many people don¹t know how to measure
ventilation or how to manage it, etc., so it becomes a big wildcard.  It
also typically needs the building to be unoccupied (unless you want to hang
out and sleep in 85¹something degrees).
