Final answer:
Water can move Class A fuels to where they can burn safely by cooling them down and suppressing the flames.
Step-by-step explanation:
Water as a mechanical tool can move Class A fuels to where they can burn safely.
Class A fuels refer to ordinary combustible materials such as wood, paper, and cloth that are not conductive to electricity.
By spraying water on Class A fuels, it cools them down and suppresses the flames, thus preventing the fire from spreading.
