Household First Aid Kit, 90 Pieces

Ninety pieces sorted into labelled compartments — dressings in one, cleaning and antiseptics in another, tools in a third — so the right thing can be found one-handed, which is often the only hand available.

Keep it somewhere every adult in the house knows about, and check the contents once a year. An expired kit that nobody has opened since it was bought is the usual state of a first aid kit.
