26 Tex. Admin. Code § 554.336 - Smoke Compartmentation (Subdivision of Building Spaces)
(a) Smoke compartmentation must be as
described in NFPA 101 and in this section.
(b) An exit sign must be provided on each
side of corridor smoke doors unless otherwise directed by HHSC.
(c) The metal frames for the wire glass view
panels in smoke doors must be steel, unless otherwise approved by HHSC. The
bottom of the view panel must not be higher than 54 inches above the floor.
Pairs of opposite (double egress) swinging smoke doors in corridors must have
push/pull hardware. The door leaves must align in the closed
position.
(d) Smoke barrier walls
in concealed spaces such as attics, must have prominent signs on each side that
read: "Warning: Smoke/fire barrier. Properly seal all openings."
(e) Provisions must be made for reasonable
access to concealed smoke barrier walls for maintaining smoke dampers and so
that walls and dampers can be visually checked periodically for conformance by
facility staff, service persons, and inspectors. Access must provide for visual
inspection of both sides of the wall, and of all parts (end-to-end and
top-to-bottom). Ceiling access panels must be prefabricated metal panel, or its
equivalent, and be at least 20 inches by 20 inches with no obstructions above
(such as ducts) to hamper entrance, and it must be fire rated if required to
maintain ceiling-roof or ceiling-floor fire rating. Access must be provided for
both sides of the wall.
(f) Air
systems should be designed to avoid having ducts which penetrate smoke barrier
walls, thus eliminating the need for smoke dampers which are often a problem to
maintain in proper working condition.
