In fire investigations, why is it crucial to assess wind speed?

Assessing wind speed during fire investigations is vital for understanding the spread of fire because wind can significantly influence how quickly and in which direction flames will travel. When wind is strong, it can carry embers and flames to new areas, intensifying the fire and potentially creating new ignition points far from the original source. This information not only aids investigators in reconstructing the fire’s development but also helps in identifying the area of origin and the factors that contributed to its spread. Knowledge of wind conditions can also assist in evaluating the efficacy of fire control efforts and help in planning for fire prevention strategies in the future. Understanding how wind interacts with buildings, vegetation, and other features of the landscape is essential for a thorough fire analysis.
