Is the glass staircase safe?

Full glass staircase: The load-bearing parts of the stairs, such as steps, pillars and structural beams, and armrest fences are all made of glass, with only a few metal fixtures or no fixtures.

Part of the glass staircase--- can be specifically divided into: steel-structured glass staircase (for structural pillars or beams, see metal structure + glass step surface + glass handrail fence). Wood-framed glass staircase (structural pillars or beams are made of wood structure + glass step surface + wooden handrail fence). Glass staircases of other constructions (for structural struts or beams, see any other non-glass material such as aluminum or cement construction + glass step surface + wooden handrail fence). Glass stair parts (only one of the armrest or step surface parts is made of glass)
