What is the main role of fire investigation within a fire department?

The primary responsibility of fire investigation within a fire department is to determine the cause and origin of fires. This essential role plays a critical part in fire prevention efforts by analyzing how and why a fire occurred. Understanding the root causes allows fire departments to implement preventative measures, educate the community about fire risks, and develop strategies to mitigate those risks in the future. This proactive approach not only enhances public safety but also contributes to the overall effectiveness of fire response efforts.

Fire investigations are primarily concerned with preventing future fires by learning from past incidents, making option B the correct choice.
