BISCI chapter 7

Question 1

The “FH” rating of a fire-rating classification is the same a an “F” rating, but requires the hose stream test

Answer 1

True

Question 2

Match the fire-stop system that bests corresponds with the system’s properties. Each selection may be used more than once.

Answer 2

Firestop putty → Endothermic and intumescent,

Firestop caulking → Ablative, endothermic, or intumescent,

Firestop pillow → Intumescent

Question 3

Under what circumstances may a fire watch be required?

Answer 3

When it is not possible to completely firestop all opening in an occupied building at the end of a shift.

Question 4

appropriate meaning of the “F”

Answer 4

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

Question 5

appropriate meaning of the “T”

Answer 5

Time period that the unexposed surface of the assembly or any penetrating item does not exceed 180 degrees Celsius

Question 6

Define annular measurement in reference to firestop systems.

Answer 6

The size of the opening and the item(s) penetrating the opening

Question 7

Match the firestop material that bests corresponds with the material properties

Answer 7

Mechanical pressure → Elastomeric,

Enlarges or swells → Intumescent,

Absorbs heat → Endothermic,

Develops a hart crust → Ablative

Question 8

Which firestop system is often regarded as temporary?

Answer 8

Firestop pillows

Question 9

Select the 4 components of a firestop system

Answer 9

Barrier being penetrated,

Construction and thickness of the barrier being penetrated,

Item penetrating the barrier,

Materials and methods used for sealing the penetration.

Question 10

The “L” rating of a fire-rating classification is the Largest Air Leakage rate, but does not simulate smoke leakage through a firestop assembly

Answer 10

False
