How does the pre-fire plan most help prepare the IC before arrival at an incident?

The pre-fire plan provides the Incident Commander (IC) with critical information about the building or area involved, such as its layout, occupancy types, and potential hazards. This advance knowledge allows the IC to develop a strategic approach and allocate resources effectively before arrival at the incident. By understanding the specific challenges and risks associated with the site, the IC can make informed decisions quickly, enhancing safety for responders and improving overall incident management.
