7 Firestopping

For all job specific firestopping issues, the information and communications technology ( ICT ) systems cabling installer should consult who

The most common fire protection principle is

Fire safety must provide: check all that apply

A fire assembly is based on: Check all that apply

Who can be held legally, criminally and financially responsible if the manufacturer's instructions are not followed.

When firestopping the installer may substitute or add more product to get a higher rating.

Time period (expressed in hours) that assembly resists flame passage

Time period that a the unexposed surface of the assembly or any penetrating item does not exceed (325 degrees) above its initial temperature

This simulates smoke leakage through a firestop assembly.

Mechanical firestop systems use _______________ firestop materials which are flexible and resemble rubber.

Non-mechanical firestop materials have three basic properties. Select the one that has the ability to absorb heat which prevents the temperature from rising on the other side of the fire barrier.

This non-mechanical firestop has the ability to expand when exposed to fire or heat. The material swells around and within the penetration to provide a tight seal.

This non-mechanical firestop develops a hard char that resists erosion from fire or flames.

Intumescent _________________ are used for plastic piping, insulated metal piping, cable bundles, plastic conduit or materials that may burn away in a fire.

____________________ are common with a long shelf life, ease of installation and wide range of applications. Most are endothermic but may be intumescent. Comes in bulk, bars or sticks.

This material may be endothermic, ablative or intumescent and are for permanent installations not intended to be re-entered.

This is sometimes referred to as a pipe choke system.

__________ are dispensed from a two part mixing tube and quickly cures to form a tight seal. May be intumescent, endothermic or ablative.

In situations where critical power or data cables must remain in operation and primarily for large air handling and exhaust vents this is used.

All components used to make up a listed assembly are designed and tested as a unit and the parts are not interchangeable.
