Which feature enhances the ability to effectively handle emergency calls in the fire department?

The feature that enhances the ability to effectively handle emergency calls in the fire department is Caller ID. Caller ID provides essential information about the incoming call, including the caller's phone number and, in some systems, additional details such as the name and location associated with that number. This immediate access to caller information allows dispatchers to respond more efficiently, ensuring that the fire department can direct resources correctly and quickly to the location of the emergency.

By knowing where the call is coming from, the fire department can also verify addresses and cross-check with existing data on fire risks or hazards in the area. As a result, Caller ID significantly improves communication and operational effectiveness during emergency situations, contributing to faster response times and better overall management of incidents.
