This week’s Extra Alarm insights come to us from Senior Captain Chris DelBello, who focuses on the dos and don'ts for commanding your first fire, including checklists for before, during and after the incident. Other topics addressed: pre-fire preparations, such as sharing expectations with firefighters, familiarizing oneself with command worksheets, and practicing size-ups; common mistakes to avoid, like being overly restrictive or switching command modes frequently; and the importance of post-fire reviews and learning from the experience.
