What it is Filled

A piece of cloth hung to block out or soften light, usually at a window, also giving privacy and some insulation; related hanging screens include shower, theatre and safety curtains.

Why it exists Filled

Let an agent describe curtains by type, material and use, and point to fire-safety standards for curtains in public buildings and theatres.

Distinguishing features Filled

  • A hanging screen; movement alone does not define it, and blinds are a separate category of covering.
  • Theatre safety curtains separate stage and audience in a fire; their performance as an assembly differs from fabric flame classification.
  • Curtains in public buildings often must meet flame-retardancy standards.

What robots and AI may and may not do Filled

Must not

  • declare a curtain fire-safe without certification

May

  • describe types and safety rules

Moral aspects Filled

  • child safety
  • fire safety

Who is affected

  • occupants
  • children

Owners Filled

Steward

the owner of each curtain or building

  • NFPA 701 fire tests for flame propagation of textiles (US)
  • EN 13120 internal blinds (excludes draperies); EN 16434 safety devices may be applied to corded draperies
