Study Notes
Fire Dynamics Research
- The UL Firefighter Safety Research Institute has been conducting research on fire dynamics for the past 10 years.
- The research focuses on understanding how fires grow and spread in homes to improve firefighter safety and efficiency.
Experimental Setup
- The project uses full-scale structures with controlled ventilation (opening doors or windows) to study the impact on fire patterns.
- Replicate fires are conducted with the building initially closed, then with openings made in subsequent tests.
- Probes measure temperature, gas velocity, and direction of hot gases and fresh air.
Data Collection
- Thermocouples measure temperature at intervals from ceiling to floor.
- Oxygen concentration is monitored at 4 feet and 4 inches above the floor.
- Pressure is monitored through taps in the wall.
- Cameras and sensors capture data on fire effects, such as ignition, flames, and smoke.
Investigation and Analysis
- The scene is documented with photographs before, during, and after the fire.
- Furniture is removed, and layers of the house are documented to analyze fire patterns.
- Data is analyzed with a technical panel of fire investigation experts to develop key findings and an online training program.
Impact and Applications
- The research aims to improve firefighter safety and efficiency by understanding fire dynamics and ventilation impacts.
- It also informs fire investigators about the impact of ventilation on fire patterns and origin.
- The project promotes collaboration between firefighters and investigators to improve overall fire safety and response.
