Household first aid supplies
$$
First 100 · item 14
The single most-used readiness purchase in any house, because minor injuries do not wait for disasters. Cuts, scrapes, splinters, and kitchen burns arrive weekly in a family household, and delayed professional care during any disruption raises the stakes on all of them. One well-stocked decision covers bandages, gauze, tape, tweezers, antiseptic, and the dozen small things a kit is for. The mistake is the sealed novelty kit from a checkout aisle, heavy on bandage count and light on everything a real injury uses.

First aid and CPR training
$$

The purchase on this list that cannot be misplaced, borrowed, or used up. Every supply below works better in trained hands, and the highest stakes moments, choking and cardiac arrest, are answered by hands rather than inventory. A standard course from the established providers takes a few hours and holds for two years. Buying more gear instead of the class is the category's signature mistake, and it is why training sits at two rather than seventeen.
03
Digital fever thermometer
$
The diagnostic backbone of home illness care, and the item households most often assume they own until the night they need it. Whether a fever is rising or breaking drives every decision that follows, from medication timing to the call about seeking care. A basic digital thermometer answers in seconds and costs a few dollars; buy two, because they hide. A hand on a forehead is a guess, and guesses get worse at three in the morning.
04
Core over-the-counter medications
$$
First 100 · item 17
The small pharmacy that handles the illnesses that actually occur: pain and fever, allergies, stomach trouble, coughs and congestion. During a disruption the pharmacy may be closed, out, or unreachable exactly when a household member spikes a fever. Stock the categories your household already uses, in adult and child strengths where both live in the house, and rotate by the dates. The mistake is depth in one bottle and nothing across the categories; variety beats volume here.

The unglamorous packets that address the most common serious complication of ordinary illness, which is dehydration. Vomiting and diarrhea drain a body faster than plain water restores it, and small children and older adults go downhill quickest. Commercial packets mixed with clean water are the standard answer, cost little, and store for years in a drawer. Sports drinks are the substitution people make, and they are built for sweat, not for illness.

The protective layer for every messy job this list describes. Treating a wound, caring for someone ill, and cleaning up afterward all go better when bare hands stay out of it, protecting both the helper and the helped. A box of one hundred nitrile gloves costs little, fits in the kit, and serves double duty for household cleanup jobs. The work gloves from the tools list are the wrong tool here; this job needs the thin barrier, not the thick one.
07
Instant cold packs and elastic wraps
$
The sprain response, for the injury category that fills more home kits with regret than any other. Twisted ankles and wrenched knees are among the most common household injuries, and cold plus gentle compression in the first hour is what keeps a bad afternoon from becoming a bad month. Shelf-stable instant packs work with no freezer, which matters during the outages when people are climbing and clearing. Kits rarely include either one, which is exactly why this line exists.
