What impact can fire have on common building materials? Some materials like wood and polastic will fuel the fire. Others like concrete and masonary will prevent or limit the spread of the fire. All materials react differently when exposed to the heat of a fire.
What are some of the issues with modern construction lumber?
Structural collapse due to lightweight building materials. Firefighter disorientation due to large, wide-open floor plans.
These factors include:
- Life hazard.
- Available resources.
- Available capabilities.
- Exposure issues.

Why do fires run so quickly through a building under construction?
In a building under construction, drywall might not be installed yet. This lack of protection from the sheetrock allows fire to spread quickly into wooden truss areas, leading to premature failure of the truss assemblies.
