IFSTA: High-Rise Firefighting (25 Questions)

Question 1

According to IFSTA’s Structural Fire Fighting: High-Rise Fire Fighting, products of combustion travel upward toward the top of a building. If fire does not generate enough heat to cause the smoke to rise to the top of the building, the temperature of the smoke will eventually equal that of the surrounding air. When this equalization of temperature occurs, the smoke loses its buoyancy, ceases to rise, and forms layers of smoke within the building. This is known as:

A) Stack effect
B) Stratification
C) Heat intensity and compartmentation
D) Ceiling jets, or mushrooming

Answer 1

B) Stratification

Answer: B (pg. 58)

Question 2

According to IFSTA’s Structural Fire Fighting: High-Rise Fire Fighting, the natural vertical movement of heat and smoke (convection) in tall structures is known as _______________. This occurs because of differences in the density of the air inside and outside of these buildings (due to temperature differences inside and outside the structure). The greater the difference between the inside and outside temperature and the greater the building height, the greater the effect will be.

A) Stack effect
B) Stratification
C) Heat intensity and compartmentation
D) Ceiling jets, or mushrooming

Answer 2

A) Stack effect

Answer: A (pg. 58)

Question 3

According to IFSTA’s Structural Fire Fighting: High-Rise Fire Fighting, when heat, smoke, and other products of combustion rise until they encounter a horizontal obstruction, they will spread laterally until they encounter a vertical obstruction, then bank downward.

B) This effect is triggered when a door is left ajar and a window suddenly breaks under intense heat and a blast of wind
C) The instant combination of fire and wind can blast fireballs across rooms and down corridors without warning, In these situations, tremendous volumes of fire and high heat conditions can quickly consume compartmented occupancies and advance into public hallways
D) If windows in the fire area are intact, firefighters on attack lines do not need to maintain coordination with those tasked with ventilation from the floor above the fire or adjacent compartmented areas
