What is a reliable source of information about a structure before an incident?

A preincident plan serves as a crucial tool for firefighters, providing detailed information about a structure before an incident occurs. It typically includes layouts, features, utilities, and any specific hazards related to the building, all of which are vital for effectively planning response strategies. This information helps firefighters understand the environment they will be working in, leading to safer and more efficient operations during emergencies.

In contrast, incident reports document events after they happen and may not provide the necessary proactive insights needed before an incident occurs. Fire code documentation pertains to regulations and compliance but does not offer specific operational details about a particular structure. Building code records focus on the design and construction aspects and may not contain the real-time operational information that is crucial for emergency responders.
