What interior feature is not identified during an outside inspection of a building?

The interior load-bearing walls of a building are not visible during an outside inspection. While conducting an exterior inspection, firefighters and inspectors can assess various features such as windows, exterior walls, and the roof structure; these elements provide insights into the building's overall condition and structural integrity. However, load-bearing walls are internal features that require access to the inside of the building to be evaluated properly. This is crucial when considering the potential need for structural support during firefighting operations or during a post-incident building assessment.

Understanding which components are accessible during an exterior inspection helps first responders make informed decisions about safety measures, tactics, and strategies while approaching a building during an emergency situation.
