This makes me think of wood dust being dangerous to inhale [1], despite wood being a perfectly safe material for furniture at home.

- rbanffy 2y agoRegolith is also considered safe, but that’s only because it’s about one light-second away.
- ted_dunning 2y agoRegolith is just a layer of rock. We have plenty of that around here. Lunar regolith or Arean regoliths are quite different. You were presumably talking about lunar regolith.
- smaudet 2y agoPer my sibling comment, I think thought must be given to the likelyhood of distribution of a "channel" or material state, not just the fact that one exists. Particularly, wood is fairly recognizable, and almost certainly not liable to spontaneously implode into a cloud of dust. Plus, I'm fairly confident it is biodegradable (even in dust form). Not sure the same can be said for most other materials, such as cadmium, or the parent mentioned naturally occuring compound.
- timr 2y agoKind of a digression, but wood dust absolutely does present an explosion risk, when mixed in the right ratio with air. It's a thing that happens, and people worry about it in industrial settings. https://www.youtube.com/watch?v=LPIZ5Movuiw https://www.youtube.com/watch?v=LPIZ5Movuiw https://www.youtube.com/watch?v=70fZqHsEdMo https://www.youtube.com/watch?v=70fZqHsEdMo
