Floor (Inventory)/Breakdown
From LagWiki
The Breakdown field of the Floor section should be used to list stations where breakdown is identified as one of the floor features.
Breakdown is collapsed cave ceilings or walls. The size can vary from small chips and flakes to much larger blocks, slabs and boulders. The size of a breakdown block is limited only by the size of the passage in which it fell.
