Fire Protection Systems Chapter 12 Questions with
CORRECT Answers (Grade A+)
Question 1:
Active Design Approach
Answer:
A design approach that used mechanical systems to prevent smoke and gas movement by exhausting,
pressurizing, and, in particular situations, opposing the smoke with forced air
Question 2:
Buoyancy Forces Upward forces that cause hot gases to rise when fire plume temperatures are
Answer:
higher than the surrounding air
Question 3:
Elevator hoistway pressurization
Answer:
A mechanical method of smoke control in which 100% outdoor air is pumped into the elevator
hoistway at an increased pressure, forming a pressure barrier that prevents smoke and gases from
entering the elevator shaft.
Question 4:
Floating Zone/Floor-by-floor Pressurization
Answer:
A mechanical method of smoke control in which 100% outdoor air is pumped onto the floors above
and below the fire floor, forming a pressure sandwich or barrier around the fire and mechanically
relieving or exhausting the air from the fire floor(s); this method is most successful when all non-fire
floors are pressurized.
Question 5:
Passive Design Approach
Answer:
A design approach that uses fixed barriers, such as walls, bulk-heads, doors, partitions, high ceilings,
and sealed floor openings, to prevent smoke and gas movement
