What process enables the OIC/OSL to determine what resources will be needed to control a situation?

The process that enables the Officer in Charge (OIC) or the On-Scene Leader (OSL) to determine what resources will be needed to control a situation is known as size up. This initial assessment involves evaluating the incident scene in order to gather vital information about the environment, hazards, and the extent of the situation.

During the size up, the OIC/OSL can identify the nature of the fire, the potential risks involved, and the resources required to mitigate the incident effectively. This includes considering factors such as the type of materials involved, the presence of personnel in the area, weather conditions, and access to the site. By conducting a thorough size up, the OIC/OSL can make informed decisions regarding the assignment of resources, strategic objectives, and tactics needed to control the situation effectively and safely.

This foundational knowledge is crucial for ensuring that the right firefighting teams and equipment are deployed to manage the incident efficiently, thus enhancing the overall safety of responders and victims alike.
