Because of the low ceilings, a ceiling jet has formed. How would you expect the ceiling jet to act in this space?
Understand the Problem
The question is asking how a ceiling jet behaves in a space with low ceilings during a fire, requiring an understanding of fire dynamics and smoke movement.
Answer
The smoke will roll across the ceiling until it finds ventilation points.
The smoke will roll across the ceiling until it finds ventilation points.
Answer for screen readers
The smoke will roll across the ceiling until it finds ventilation points.
More Information
In a fire scenario with low ceilings, the hot gases form a ceiling jet, which will roll along the ceiling in search of escape paths, such as ventilation openings.
Tips
A common mistake is confusing the behavior of fire with that of the associated smoke and hot gases. The fire itself does not 'roll' across the ceiling.
