What is the name of the arrival report provided by the first responding unit?

The arrival report provided by the first responding unit is known as the size-up report. This report is crucial for establishing an understanding of the incident scene and involves assessing various factors such as the type of emergency, the conditions present, the presence of any hazards, and the resources required. The size-up report helps to convey critical information to dispatch and other responding units, enabling them to effectively manage the incident.

In practice, this report provides a snapshot of the situation that assists command in making informed decisions quickly. It includes initial observations about fire conditions, potential threats to life and property, and recommendations for tactical response. The emphasis on size-up highlights the importance of situational awareness and the need for a systematic assessment of the emergency, which is essential for effective incident management.
