Based on the following, if there are not enough crews available to complete all tasks, which will be completed first? ICs use three other principles regarding available crews: When an IC finds that there is insufficient manpower to perform necessary tasks, the tasks that protect the most life or property are completed first. If sufficient manpower is in place and available, then the IC may coordinate both rescue and fire attack. Finally, if a scenario involves no life-safety threats, then tactics turn to protecting property as long as it does not place firefighters in unnecessarily dangerous situations.
