Isn't this also a danger with volcanic ash? It's not the composition, it's the micro-sharp-edges that haven't been dulled by getting blown around in the wind?

Isn't this also a danger with volcanic ash? It's not the composition, it's the micro-sharp-edges that haven't been dulled by getting blown around in the wind? And it will likely be true of any non-atmospheric planet? I guess the good news is that mars probably won't have this problem.
