The safety curtain can be combined with other safety devices, such as: •
Smoke pockets - are steel channels located at either side of the proscenium arch that the safety curtain travels within to create a physical barrier between the auditorium and the stage. The safety curtain is not intended to create an air seal but rather prevent material from falling from the stage house into the audience. •
Fire doors - that automatically close any doorway onto the stage in the event of a fire. •
Smoke vents - vents above the stage which will allow
smoke to move out of the roof of the theatre, enabling safer evacuation of the audience. •
Water curtain -
sprinkler heads or other nozzles directly in front of the
proscenium to prevent sparks from flying off the stage or to extinguish any burning material (such as a set) which may fall through the
proscenium. ==References==
