How does a fire spread throughout a building
WebThe maximum volumetric flow through an open stairwell door was 0.14 m 3 /s for a tight envelope and 1.02 m 3 /s for a very leaky envelope. This represents an increase of 620%. The increased airflow in stairwells result in the spread of air and potential contaminants throughout buildings. Web2. Oxygen: Oxygen always facilitates the combustion process. It allows the fire to spread and not to blow off. This is why we have been taught to cover people on fire with thick blankets to allow oxygen to die out. So with wind blowing and oxygen in there, fire is bound to spread in the direction the wind blows. 3.
