Use this tutorial while you are reviewing each PSU over satellite imagery (Tutorial B1, B2, or B3). When you discover a PSU that is in an insecure or inaccessible location, and/or visual inspection of satellite imagery shows that there are none (or very few) habitable buildings (e.g., because the PSU is located over a power plant, airport, or graveyard), then use this tutorial to (systematically or randomly) select a suitable replacement PSU.
