When does the size-up process of an emergency incident begin?

The size-up process of an emergency incident begins before an incident is reported and continues throughout the event. This is because size-up involves gathering information and assessing a situation to determine the appropriate response and resource allocation.

Understanding the context before any formal report allows responders to mentally prepare and conceptualize potential scenarios based on prior knowledge of the area, risks, and current conditions. This early assessment is crucial for effective decision-making and planning, enabling first responders to act promptly and efficiently when they arrive on the scene.

Continuing the size-up throughout the incident ensures that responders remain aware of changing conditions and can adapt strategies as necessary to ensure safety and effectiveness. This ongoing evaluation is vital for situational awareness and helps anticipate challenges that may arise as the incident evolves.
