For all job specific firestopping issues, the information and communications technology ( ICT ) systems cabling installer should consult who
Fire marshall
OSHA
AHJ
Client
The most common fire protection principle is
containment
compartmentation
extinguishing
Fire safety must provide: check all that apply
detection
suppression
ventilation
A fire assembly is based on: Check all that apply
fire barrier
construction
penetration
firestop material
Who can be held legally, criminally and financially responsible if the manufacturer's instructions are not followed.
the installer
the contracted company
the supplier
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
F rating
T rating
L rating
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.
Intumescent
Elastomeric
Endothermic
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.
Ablative
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.
Sheets
Pads
Wrap strips
____________________ 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.
Caulk
Firestop putty
wrap strips
This material may be endothermic, ablative or intumescent and are for permanent installations not intended to be re-entered.
Foams
This is sometimes referred to as a pipe choke system.
Sleeve systems
Collars
__________ are dispensed from a two part mixing tube and quickly cures to form a tight seal. May be intumescent, endothermic or ablative.
Putty
Foam
In situations where critical power or data cables must remain in operation and primarily for large air handling and exhaust vents this is used.
Firestop blankets
Pillows
All components used to make up a listed assembly are designed and tested as a unit and the parts are not interchangeable.
Which methods can limit the potential for problems and provide a better long term solution to firestopping Check all that apply
Retrofit split sleeves or sleeve systems
core bore seals
pathway barrier penetration plates ( PBPPs)
