Heh. Because she comes from a snowy place. Fire is could. Also, when you live in a snowy place that is wet "Kill it with fire" is a very viable response; there's not exactly much danger of the environment catching fire after all.

Coincidentally, this is the reasoning I think is behind Weiss using Fire Dust in the Emerald Forest during Initiation. She comes from Atlas, and is probably used to being in snowy conditions for fighting, where forest fires aren't as big a risk. They can still happen, but they're not going to happen as often as someone in Vale missing with a fireball. And this is why she hasn't used fire dust since; she's learnt that Vale is very flammable with all it's trees and lack of snow. Ice is a much safer dust to use.
