Final answer:
The incident commander should focus on identifying potential hazards, determining available resources, and developing a fire suppression strategy during pre fire planning, excluding assessing the weather forecast which is a concern for operational planning.
Step-by-step explanation:
During pre fire planning, the incident commander should focus on all of the following except assessing the weather forecast. The primary responsibilities of an incident commander during this planning phase include identifying potential hazards, determining available resources, and developing the fire suppression strategy. These tasks are crucial to ensure that emergency responders are prepared to search burning buildings to locate victims, rescue victims from various hazards, and properly use equipment and communication tools to handle an incident efficiently and effectively. Assessing the weather forecast, while important in the context of predicting fire behavior and making tactical decisions, is not the main focus during pre-fire planning but rather a factor considered in operational planning and real-time strategy.
