What is an example of an internal exposure in a building fire?

An example of internal exposure in a building fire refers to conditions or materials that are present within the structure that can cause harm or exposure to firefighting personnel. Uninvolved rooms or parts of the building can still have hazardous conditions, such as heat, smoke, and toxic gases, that can compromise the safety of responders.

In the context of internal fire situations, even though certain areas may not be directly involved in the fire, they can still be affected by the fire's byproducts or its effects—such as increased temperatures, smoke accumulation, or potential structural hazards as the fire progresses. Thus, these areas can pose significant risks to firefighters who may venture in or operate nearby, making them relevant factors in assessing internal exposure risks during firefighting operations.
