What is a critical factor to assess during interior fire operations?

Assessing the potential for structural collapse during interior fire operations is crucial for ensuring the safety of firefighters and effectiveness of the operation. Structural integrity can be compromised due to the fire's intensity, the materials involved, and the duration of the fire. Prioritizing this assessment allows incident commanders to make informed decisions about the use of resources and strategic approaches to firefighting.

For example, indicators such as visible stress in the structure, smoke conditions, and the fire's behavior can inform the likelihood of a collapse. If collapse risks are high, it may necessitate an evacuation or a defensive strategy to protect personnel. Understanding these risks helps maintain safety, reduces injuries, and enhances overall operational effectiveness.
