Decide what to salvage by ranking each item on how hard it is to make from scratch and how soon you will need it. Items that are impossible or very difficult to replace and needed soon go first; an item you cannot justify in one sentence as keeping someone alive over the next 30 days is left for a return trip. In practice that gives four tiers: immediate survival gear, medical supplies, tools with seeds and reference books, and strategic reserves.
Part of Priority Salvage List
Ranking by replaceability, urgency and weight lets you judge an item the list never names, and the same questions apply on every trip.
Hard-To-Replace Items Outrank Heavy Or Familiar Ones
You cannot take everything. Time, carrying capacity and safety are all limited, and every minute spent inside a damaged building is a minute of risk. The framework rests on one principle: prioritise what is impossible or extremely difficult to make from scratch, in the order you will need it.
A wool blanket takes months to produce from raw fleece. A box of matches depends on an industrial chemical supply chain. A bottle of antibiotics cannot be made without a pharmaceutical laboratory. Those are worth a trip into a damaged building. A wooden spoon is not, because anyone can carve one.
Four Questions To Ask About Any Item
- Can I make it, and how long would that take? Things that take seconds to improvise stay behind; things that take months or a factory come out.
- What does it prevent, and how fast? (An item you cannot justify in one sentence as keeping someone alive over the next 30 days is left for a return trip.) Exposure and dehydration kill in hours to days, untreated infection in days to weeks, hunger in weeks. Rank by how soon the item stops being optional.
- What does it weigh against what it does? See Carry Capacity vs. Value.
- What does it cost to get? A building that has already shifted, a site others are watching, or air that smells wrong all raise the price. See Competition & Risk Assessment.
The Four Tiers
- Tier 1, immediate survival gear: containers and water treatment, shelter and warmth, fire, cutting and prying tools. See Tier 1: Immediate Survival Gear.
- Tier 2, medical supplies: trauma gear, first-aid kits and medications. See Tier 2: Medical Supplies.
- Tier 3, tools, seeds and reference: hand tools, preserved food and seeds, books and maps. See Tier 3: Tools, Seeds & Reference.
- Tier 4, strategic reserves: fuel and energy, communications, barter goods. See Tier 4: Strategic Reserves.
The tiers are an order of urgency, not a ban on later items. A tier 3 item sitting in the same aisle as a tier 1 item is taken on the same trip if you have the capacity and the building is safe.
Common Mistakes
- Taking what is familiar rather than what is scarce. A generator is memorable; it is dead weight without fuel and a place to run it.
- Packing to the limit on the first trip. A full pack leaves no room for the water container or blanket you find at the next shelf.
- Treating the list as fixed. If you or someone in your group depends on a particular medicine, that medicine moves to the top whatever tier the list gives it.
Safety
A damaged building is the biggest risk in the plan
The ranking tells you what is worth entering for; it does not make entering safe. Do not go into a structure that has leaned, cracked or sagged, and do not enter anywhere with only one way out. Check each site first as described in Competition & Risk Assessment.
