Fire Seperations Fire Barriers Fire Partitions Fire Walls Horizontal Assembly Defective Fire Walls Structural Members

A fire-resistance-rated flooror roof assembly of materials designed to restrict the spread of
fire in which continuity is maintained. JOINT. The linear opening in or between adjacent fire-resistance- rated assemblies that is designed to allow independent
movement of the building in any plane caused by thermal, seismic,
wind or any other loading.

MEMBRANE PENETRATION

An opening made through one side (wall, floor or ceiling membrane) of an assembly.
MEMBRANE-PENETRATION FIRESTOP. A material, device or construction installed to resist for a prescribed time period the passage of flame and heat through openings in a protective
membrane in order to accommodate cables, cable trays, conduit, tubing, pipes or similar items.

 

MINERALFIBER

Insulation composed principally of fibers manufactured from rock, slag or glass, with or without binders. MINERALWOOL. Synthetic vitreous fiber insulation made by melting predominately igneous rock or furnace slag, and other inorganic materials, and then physically forming the melt into fibers.

PENETRATION FIRESTOP

A through-penetration firestop or a membrane-penetration firestop.

 

SELF-CLOSING

As applied to a fire door or other opening, means equipped with an approved device that will ensure closing after having been opened.

SHAFT

An enclosed space extending through one or more stories of a building, connecting vertical openings in successive floors, or floors and roof.

SHAFT ENCLOSURE

The walls or construction forming the boundaries of a shaft.

 

SMOKE DAMPER

A listed device installed in ducts and air transfer openings designed to resist the passage of smoke. The device is installed to operate automatically, controlled by a smoke detection system, and where required, is capable of being positioned from a fire command center.

SPLICE

The result of a factory and/or field method of joining or connecting two or more lengths of a fire-resistant joint system into a continuous entity.

T RATING

The time period that the penetration firestop system, including the penetrating item, limits the maximum temperature rise to 325°F (163°C) above its initial temperature
through the penetration on the nonfire side when tested in accordance with ASTM E 814.

THROUGH PENETRATION

An opening that passes through an entire assembly.

THROUGH-PENETRATION FIRESTOP SYSTEM

An assemblage of specific materials or products that are designed, tested and fire-resistance rated to resist for a prescribed period of time the spread of fire through penetrations. The F and T rating criteria for penetration firestop systems shall be in accordance with ASTM E 814. See definitions of “Frating” and “T rating.”
