Which of the following is NOT a factor influencing fire growth?

Fire growth is influenced by several key factors, including fuel type, weather conditions, and container size.

Fuel type plays a critical role as different materials ignite and burn at varying rates and intensities. For instance, flammable liquids can lead to rapid fire spread compared to solid materials like wood.

Weather conditions, such as humidity, wind speed, and temperature, can significantly impact fire behavior. For example, high winds can carry embers away from the original fire source, increasing the potential for rapid growth and spread.

Container size also affects how a fire develops. A larger container might allow for more fuel and sustain combustion for a longer period compared to a smaller one, which can lead to a quicker extinguishment if it runs out of available fuel.

In contrast, documented witness statements are not factors that influence the physical growth of a fire. While they can provide valuable information regarding the circumstances surrounding a fire incident, they do not have an impact on how a fire will grow or spread once it has already begun. Therefore, witness statements are more relevant in the investigative and analytical processes rather than in determining the dynamics of fire growth.
