Got a few quick points to keep in mind before you head in: 1. Scope the perimeter – look for any obvious collapse or weak spots. 2. Check the air – use a handheld meter for rad, CO, and gas leaks. 3. Power source – find any old wiring or batteries, but don't touch anything hot. 4. Water lines – see if any piping is intact or if there's a flood risk. 5. Doors and seals – test them for easy exit or entrapment. 6. Storage – skim for any hazardous materials or unexploded ordnance. Run through that checklist, tag what you find, and you’ll know if it’s safe to roll in. Good luck, and keep your eyes peeled.
