Telecommunicators need to know the location of the emergency and the to initiate a dispatch:

Telecommunicators play a critical role in the emergency response process, and their ability to gather essential information quickly and accurately directly impacts the efficiency of response efforts. Knowing the nature of the situation is paramount because it allows telecommunicators to assess the type of emergency at hand—whether it’s a fire, medical emergency, hazardous materials incident, or another crisis. Identifying the nature of the situation helps in determining the appropriate resources to allocate, including the types of units and personnel needed to respond effectively.

Understanding the nature of the situation also aids in prioritizing calls based on urgency and severity, contributing to overall scene safety and effective incident management. The information gathered regarding the nature of the emergency can inform responders about specific risks or requirements they may face upon arrival, such as the need for specialized equipment or training.

While factors like the severity of the situation, the identity of the reporting party, and the callback number are important as well, the nature of the situation is foundational and typically the first priority when initiating a dispatch. It sets the tone for the response and shapes the entire incident approach.
