What should firefighters look for in a structure before entering?

Firefighters should prioritize identifying safe egress points before entering a structure. This is crucial because having established exit routes ensures that personnel can evacuate quickly and safely in case of an emergency or unexpected fire behavior. Knowing the layout of the building and where the exits are located can significantly reduce risk during operations, especially when visibility and conditions inside are compromised.

While the presence of occupants is an important consideration, it primarily impacts search and rescue priorities rather than egress planning. Understanding the materials used in construction is valuable for predicting fire behavior, but it does not directly affect the immediate safety of exiting the building. Lastly, windows may be used for ventilation or access, but they are not reliable egress points in most scenarios. Thus, identifying clear and safe paths for exit stands as the most critical factor for the safety of firefighters entering a hazardous environment.
