What does ongoing size-up refer to?

Ongoing size-up refers to the continuous assessment of the evolving situation during an incident. This process is crucial for incident commanders as it involves constantly gathering, analyzing, and reassessing information related to the incident. The dynamic nature of emergencies requires leaders to stay updated on changing conditions, such as fire behavior, resource needs, and the safety of personnel involved. By maintaining an ongoing size-up, incident commanders can make informed decisions, adapt strategies, and ensure that the response efforts align with the current situation. This proactive approach is vital for the effective management of incidents and helps in mitigating risks as circumstances evolve.
