According to the Rules of Engagement, what should you size up before operations?

In the context of firefighting and tactical operations, sizing up the Tactical Area of Operation is crucial before initiating any operations. This refers to assessing the specific area where the operation will take place, which includes understanding the layout, identifying potential hazards, and recognizing critical factors that could influence the operation's success.

By evaluating the Tactical Area of Operation, fire officers can determine the best strategies for deploying resources and personnel effectively, ensuring that safety protocols are in place. This assessment allows for a thorough understanding of the environment and can inform decisions on how to approach the incident, prioritize objectives, and coordinate responses with other units. An accurate size-up of this area is essential for formulating an effective tactical plan and minimizing risks to personnel and the public.
