What type of supplies are considered expendable?

Expendable supplies are defined as items that are consumed or deteriorated in use. This classification means that these supplies are intended for one-time use or limited duration before they are rendered unusable. Examples include items like food, cleaning supplies, and basic consumables that get used up and need to be replaced after their usage.

In contrast, the other options describe different types of supplies that do not fit the definition of expendable. Supplies that are stored and never used, for instance, would be categorized as stock or reserve items rather than expendable. Supplies requiring strict accountability would fall under durable or non-expendable items, as they have a longer life cycle and are tracked for inventory purposes. Lastly, supplies provided only for emergencies may be managed differently and not used regularly, hence not fitting the expendable category either.
