What does the term 'ambient' refer to in fire investigations?

The term 'ambient' in fire investigations refers specifically to the surroundings or environment in which a fire occurs. This encompasses factors such as the surrounding temperature, humidity, and any available materials or structures in proximity to the ignition source. Understanding the ambient conditions is crucial for investigators as it helps them assess the fire behavior, the potential spread of flames, and the impact of environmental factors on the incident. By evaluating the ambient environment, investigators can gather insights into how these elements influenced the development and spread of the fire, which is essential for determining the fire's origin and cause.
