The choice regarding building materials used is significant because different materials have varying degrees of flammability, thermal conductivity, and structural integrity when exposed to high temperatures. For example, wood is more combustible than steel or concrete, meaning that structures made from wood can catch fire more easily and allow flames to spread rapidly. Additionally, some materials may emit toxic smoke or fumes when burned, further complicating fire scenarios. The composition of walls, roofs, and other structural elements directly influences how a fire behaves and spreads within and between buildings.

In contrast, while the number of floors, color of paint, and location of windows can play roles in fire dynamics—such as creating potential escape routes or affecting ventilation—they do not have the same level of direct impact on the ignition and combustion characteristics of a fire as the building materials themselves do. Therefore, understanding the materials used in construction is essential for evaluating fire risk and developing effective firefighting strategies.
