What factor is NOT considered when predicting the movement of fire?

When predicting the movement of fire, the type of flooring material is not typically prioritized as a primary factor. While flooring material can affect fire spread, it is generally not as significant as the other options listed.

The size of the building can greatly influence how fire spreads and how it can be contained, as larger structures may have more complex layouts and potential for fire to travel. Ventilation openings are critical in understanding how oxygen can fuel the fire and how smoke may escape, thus affecting the overall fire dynamics. Wind direction plays a crucial role as it can carry flames and embers, significantly impacting the rate and direction of fire spread, especially in outdoor environments.

In summary, while flooring material may have some importance, it is often overshadowed by these more critical factors that have a direct impact on fire behavior and prediction.
