What happens here

The demonstration begins by illustrating how rapidly fire can engulf a house, highlighting that a house can be fully engulfed in as little as five minutes. A small model house, partially enclosed with clear plexiglass, is used. Smoke is introduced into the model to show how limited visibility becomes during a fire, necessitating vertical ventilation. Vertical ventilation is then simulated by opening the peak of the roof on the model, demonstrating how it allows smoke and heat to escape, improving visibility and conditions inside the structure.

Goal: Illustrate rapid fire spread and the necessity of vertical ventilation

Tools and materials

  • Model House Custom Built — To simulate a house fire scenario and demonstrate smoke movement
  • Plexiglass Sheet — To enclose the model house while allowing visibility of smoke
  • Small Fire Source — To generate smoke for demonstration purposes

What they say

Hide

A thousand US houses burn down every day. It takes as little as 5 minutes for a house to be fully engulfed in flames. This is why firefighters have to act so fast in a fire. When a fire starts in a house, there's limited visibility. Firefighters have to create vertical ventilation to allow the smoke to rise and clear out the space. Here's a joist bay and we have the first floor and the second floor. When there's no blocking and a fire starts on a lower level, this heat allows this to rise and come out in
