When soap and water are unavailable, use hand sanitizer with at least 60% alcohol as directed. Soap and water are needed for visibly dirty or greasy hands. Young children need adult supervision. Never swallow sanitizer, make mixtures, or use it near flames.

Worked example

The fictional label says hand sanitizer, 70% alcohol. That meets the alcohol threshold, but the person still must follow directions, cover hand surfaces and rub until dry. It is not a drink or a guarantee against all germs.
