Tier nine extends two clocks. The first is medical: the seven-day prescription buffer from tier two grows to thirty days, wound care deepens past the household kit, and the entries turn toward the people whose dependence on a device or a medication makes a supply interruption a different kind of event. The second is mobility: most people are not home when things happen, and a vehicle that can start itself, hold its air, and carry a night's worth of warmth is preparedness for the majority of hours in a life.
This tier also contains the most contested exclusion in the document, and it deserves its argument in the open. Tourniquets save lives, the bleeding-control movement that promotes them is right about that, and this list still does not include one as a purchase. The reason is the same precedent set at item 15: where a capability is dangerous to improvise, training precedes equipment, every time. A tourniquet bought, binned, and never trained on is the item most likely to be applied wrong by a frightened person, and the counterfeits that dominate online marketplaces make the untrained purchase worse still. Take a bleeding-control class, then buy a real one from a verified supplier. That is not a refusal. It is a sequence, and sequence is what this document is for.
A quieter theme runs under the conditional items here. Spare glasses, hearing aid batteries, a glucometer with strips: general-purpose lists drop these because they do not apply to everyone, and the households that need them are exactly the ones least able to improvise around their absence. A list built for real households makes room for the ways real households differ.
The threshold
Your household can handle a longer medical interruption, and get home or get out in a vehicle that is ready.
Rough tier cost: $150 to $450, varying widely with the conditional items.
