Which of the following is NOT an appropriate action for members at a fire scene involving possible arson?

Clearing the scene as fast as possible is not an appropriate action at a fire scene involving possible arson because preserving evidence is critical in such investigations. When arson is suspected, it is essential to maintain the integrity of the scene to allow for a thorough examination and collection of potential evidence. This can include physical evidence, such as incendiary devices or accelerants, as well as clues that could help determine the cause of the fire.

Actions such as preserving potential evidence, notifying the fire marshal, and establishing a command post are vital components of managing a fire scene. These steps facilitate a detailed investigation and ensure that all relevant information is documented and analyzed properly. Removing or altering the scene hastily could compromise the investigation and hinder efforts to determine the cause and identify any suspects involved in the arson. Therefore, taking the necessary time to assess and handle the scene appropriately is of utmost importance.
