Which card is a primary reference during the Call Receiving phase?

The primary reference during the Call Receiving phase is the All Callers Interrogation Card. This card is essential as it provides emergency dispatchers with a structured format to systematically collect necessary information from the caller. This includes critical details about the nature of the emergency, the condition of the patient, and any specific hazards present, which are vital for determining the appropriate response.

Gathering this information effectively during the initial phase lays the foundation for the accurate assessment and prioritization of the call, ensuring that the dispatch team can relay essential details to responding units swiftly. By using the All Callers Interrogation Card, dispatchers can maintain consistency in the information gathered, thereby enhancing communication and efficiency throughout the emergency response process.

While the other cards serve important roles, such as providing specific instructions or handling particular complaints, they are not the primary tool for initiating the call process and gathering essential information from the caller.
