What are the two exposure classifications in firefighting?

• A. Interior and Exterior
• B. Primary and Secondary
• C. Hidden and Exposed
• D. Structural and Non-Structural

Answer: (A)

Exposure refers to items or areas that could be affected by the fire or that could spread the fire. The two classifications are interior exposures and exterior exposures.

Interior exposures are parts of the structure or rooms inside the building that are at risk from radiant heat, smoke, or flame from the fire. Tactics here focus on protecting these spaces, aiding occupants, and controlling the fire's progression inside through ventilation and access.

Exterior exposures are items outside the burning area, such as neighboring rooms or adjacent buildings, fences, vehicles, or siding. Tactics center on preventing ignition of these exposures by cooling surfaces, applying water to the outside of the burning building, and creating defensible space to stop the fire from spreading.

So, the best answer is interior and exterior because it reflects where the things at risk lie relative to the fire.
