Theater Fire Curtains & Stage-House Asbestos — Asbestos Exposure Crosswalk

What This Equipment Is

The proscenium fire curtain (also called an asbestos curtain, fire safety curtain, or stage fire curtain) is the rigid fire-rated barrier that drops between the stage house and the audience seating area during a stage fire to prevent fire and smoke spread. From the late nineteenth century through the late 1970s, the dominant material for proscenium fire curtains in U.S. theaters was woven asbestos cloth — heavy, fire-resistant, dimensionally stable under load.

Related theater asbestos products included:

  • Stage drapery and tabs — selected fire-rated curtains beyond the main fire curtain
  • Stage rigging asbestos cord — fire-rated trim and ties
  • Stage-floor traps and lift covers — asbestos millboard backers
  • Stage-house lighting cable insulation — asbestos paper-wrapped feeder cables for high-current stage lighting
  • Orchestra-pit lift brakes — see Elevator Brake Shoes

Theater asbestos installations were common in commercial theaters, school auditoriums, college performing-arts buildings, civic centers, and church/synagogue stages.

Why Theater Asbestos Was an Asbestos Exposure Pathway

Theater workers — stagehands, technical directors, stage carpenters, scenery crews, lighting crews, riggers — handled the fire curtain and surrounding asbestos installations regularly. The curtain was tested periodically per fire-code inspection requirements, raising and lowering it (and disturbing fiber from the woven asbestos cloth at each cycle).

Renovation and demolition of historic theaters during 1980s–2000s restoration projects exposed crews to legacy fire curtains, asbestos rigging, asbestos-bearing scene drops, and surrounding asbestos building materials.

School and college theater retrofits — replacing aging fire curtains with modern fire-rated alternatives — drove concentrated asbestos-curtain removal projects in the 1990s and 2000s.
