When should the Size Up process begin?

The Size Up process is critical for effective incident management and should begin prior to the incident itself. This proactive approach allows responders to prepare adequately for potential emergencies by assessing risks, resources, and strategies that may be required. By conducting a thorough Size Up before incidents occur, fire personnel can identify key factors such as environmental hazards, buildings' conditions, access routes, and available support resources, which ultimately enhances operational efficiency and safety during an emergency response.

Understanding this pre-incident evaluation is essential because it sets the groundwork for informed decision-making, helping to ensure that teams are ready to address challenges as they arise. This foresight can significantly impact the effectiveness of the response and the safety of both responders and civilians involved.
