Some piles of trash are scenery in Control Center. Understand "broken/equipment/junk" as piles of trash.
The smell of gasoline is fixed in place in Control Center. "[if player holds scent]You can clearly smell gasoline coming from under that [sheet of corrugated metal][otherwise]You catch a faint whiff of gasoline coming from somewhere[end if]."
