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

Select the appropriate meaning of the “F” rating of a fire-rating classification.
- Time period that the unexposed surface of the assembly or any penetrating item does not exceed 180 degrees Celsius,
- Time period (expressed in hours) that the assembly resists flame passage.
“F” rating → Time period (expressed in hours) that the assembly resists flame passage.
Select the appropriate meaning of the “T” rating of a fire-rating classification.
- Time period that the unexposed surface of the assembly or any penetrating item does not exceed 180 degrees Celsius,
- Time period (expressed in hours) that the assembly resists flame passage.
“T” rating → Time period that the unexposed surface of the assembly or any penetrating item does not exceed 180 degrees Celsius,
Under what circumstances may a fire watch be required?
A. During the firestop installation
B. Anytime you are penetrating a fire barrier in an occupied building.
C. When it is not possible to completely firestop all opening in an occupied building at the end of a shift.
D. When building operators are not present.
When it is not possible to completely firestop all opening in an occupied building at the end of a shift.
Define annular measurement in reference to firestop systems.
A. The material of the opening and the item(s) being penetrated.
B. The size of the opening and the item(s) penetrating the opening.
C. The size of opening and the items being penetrated.
D. The size of the item(s) penetrating and the material being penetrated.
The size of the opening and the item(s) penetrating the opening.
Which firestop system is often regarded as temporary?
A. Firestop pillows
B. Cement
