What is a limitation of a 360-degree size-up?

The limitation associated with a 360-degree size-up is that it can be perceived as 'flat', which suggests a lack of depth in understanding the situation. In the context of fire tactics, a 360-degree size-up is essential as it allows firefighters to assess the structure and surroundings comprehensively by observing all sides of a building. However, simply doing a complete visual survey does not necessarily provide a comprehensive understanding of internal conditions, such as smoke movement, fire intensity, or structural integrity, which are crucial for making informed decisions.

A flat assessment can lead to oversights in critical areas, as it may not effectively convey the nuances of the situation, like hidden fire extension or compromised structural elements that are not visible from the exterior. In order to combat this limitation, firefighters must complement the 360-degree view with additional information gathering—such as verifying knowledge of building construction, possible occupants, and historical data of the site—ensuring a more holistic situational awareness beyond the immediate visual assessment.
