Escape stairs. I recycled this set of escape stairs from another show. You’ll notice the platform on the floor. The other set of stairs to the right were built for this height.
All escape stairs are to have railings. These stairs were built using 2×6 stringers and two layers of 3/4″ ply for the treads. The cast was advised to use these stairs as ladders and climb down backwards. This is because of the angle.
