What is a key detail for the preservation of evidence at a fire scene?

A key detail for the preservation of evidence at a fire scene is to start the collection process as soon as possible. Timeliness is crucial in gathering evidence because the integrity of the scene can change rapidly due to various factors such as the elements, potential tampering, and ongoing investigations. Prompt action helps ensure that evidence is preserved in its original state, which is vital for accurate analysis and subsequent legal proceedings.

By starting the collection of evidence as soon as it is safe to do so, investigators can secure critical materials that may be lost or compromised if the scene is not handled quickly. This process not only aids in determining the cause of the fire but also helps in identifying potential criminal activity if applicable.
