Yoshioka Lab
Machine-translated · View original
The lab studies how buildings burn and how to prevent it, working in fire safety engineering to protect buildings and cities from fire.

AboutAbout the lab
Fire safety engineering to protect buildings and cities from fire.
Yoshioka Lab specializes in building fire safety engineering and urban fire safety, conducting engineering research on safety against fire.
The lab works on topics such as fire spread across combustible exterior walls, the toxicity of gases produced in fires, and fire prevention measures during construction work.
The lab carries out its research through fire experiments and computer-based fire simulations, in collaboration with research institutions and companies in Japan and abroad.
In addition to the topics introduced here, students can also take up topics related to fire safety in general and evacuation safety during fires.
Key terms
- Fire CFD
- A method that uses computers to calculate the flow of air and smoke and the transfer of heat, in order to reproduce how a fire spreads
- FTIR
- An analytical instrument that irradiates a substance with infrared light and determines the components of gases and other materials from which wavelengths of light are absorbed
- Sandwich panel
- A panel made by sandwiching insulation material between steel sheets on both sides. It is used for the interiors of cold storage warehouses and clean rooms

The lab specializes in building fire safety engineering and urban fire safety, conducting engineering research on safety against fire. In collaboration with institutions in Japan and abroad, it investigates fire spread across exterior walls, the toxicity of gases produced in fires, fires during construction work, and the burning behavior of interior panels.
*Illustrative imageFire spread across combustible exterior walls
It has been confirmed in Japan and abroad that combustible materials on the outside of an exterior wall can lead to severe fires. In collaboration with organizations such as FM Global (USA), the lab studies the mechanisms of fire spread and countermeasures using fire experiments and fire CFD.
*Illustrative imageEvaluating the toxicity of fire gases
In collaboration with the Building Research Institute, the University of Poitiers (France), and others, the lab studies the toxicity of gases released from materials in fires. It analyzes the gases produced in small-scale fire tests using FTIR and compares the results with those of mouse tests.
*Illustrative imagePreventing fires caused by welding sparks
The lab studies fires caused by sparks from welding and cutting during construction work that land on insulation materials. In collaboration with the Fire and Disaster Management Agency, the Building Research Institute, and private companies, it analyzes fire patterns and investigates effective countermeasures.
*Illustrative imageBurning behavior of sandwich panels
Sandwich panels, which are widely used for the interiors of facilities such as cold storage warehouses, can burn fiercely in real fires. In collaboration with other universities and companies, the lab conducts fire experiments at different scales and investigates construction methods that resist fire.
