What information must the incident commander provide to the fire alarm office after arrival?

The incident commander must provide the address of the incident to the fire alarm office after arrival because this information is critical for several operational reasons. The address helps ensure that all relevant units and personnel are aware of the exact location of the emergency, which is essential for coordinating an effective response. It also aids in maintaining accurate records and assists in further dispatching if additional resources are needed.

While other information such as weather conditions, personnel availability, and equipment status may be important for overall situational awareness and safety, the address is fundamental for the immediate operational response and communication with the fire alarm office. This ensures that all resources are properly directed and that there's a clear understanding of where the incident is taking place.
