The speed of fire spread is influenced significantly by various environmental and physical factors, which is why the focus on fuel type, wind, temperature, and building materials is essential.

Fuel type refers to the materials involved in the fire; different materials ignite, burn, and spread heat at varying rates. For instance, wood burns slower than gasoline, which is highly flammable. Wind can carry embers and flames, causing the fire to spread more rapidly in one direction or to new areas entirely, making it a critical factor to consider. Temperature affects the ignition point of materials and can influence how quickly a fire spreads; higher temperatures can lead to quicker ignition of surrounding materials. Lastly, building materials also play a role; structures made from fire-resistant materials may slow the spread of fire, while those made from combustible materials can promote faster fire development.

In contrast, while firefighter training and experience are vital for effectively combating a fire, they do not directly influence how quickly a fire spreads. Similarly, call volume may indicate how many incidents the firefighters are managing, but it does not have a direct impact on the fire itself. Lastly, while time of day and weather forecasts may suggest potential changes in conditions, the immediate factors affecting fire behavior at the moment are more critical.
