Emergencies & HazardsCâu 89 / 120
A grease or fuel fire starts near the engine. Why must you never use water on it?
a.Water is too heavy to carry
b.Water freezes on hot metal
c.Water damages the paint
d.Water spreads burning liquid instead of putting it out
Giải thích
Burning liquids float on water, so a stream of water scatters the fire over a larger area. Weight, freezing, and paint damage are irrelevant compared with the danger of spreading a Class B fire.
