A good idea with what to do with slag chunks and rocks

[MeowRailroad]

Put a dumping stockpile around your solar panels and allow it to fill up with chunks. Then, if there are electrical fires, the chunks should prevent or at least deter spread of fires. Also you could do this inside battery rooms.

or, you know, just build a floor made of <insert whatever material here>

I prefer to use e.g. stone floors for that. makes walking over it easier.

A maybe better use for a rock dumping stockpile would be to place it around your base entries so that melee attackers are getting slowed down and maybe a bit spaced out so that you can pick them off more easily from the distance. Just smelt the slags, nets you some metal.
