What is one function of the international emergency number 911?

One primary function of the international emergency number 911 is to connect callers with emergency services. When someone dials 911, the call is routed to a public safety answering point (PSAP), where trained dispatchers assess the situation and coordinate the appropriate emergency response. This can include sending police, fire, or medical assistance based on the caller's needs. The system is designed to provide immediate access to help during critical situations, ensuring that individuals can quickly reach the resources necessary to address an emergency, which is crucial for saving lives and minimizing harm.

The other options do not represent the primary role of the 911 system. For example, while hospitals may receive emergency patients conveyed by ambulances called through 911, the number is not specifically for direct communication with hospitals. Additionally, educating callers on first aid goes beyond the dispatching function and is not a feature of 911. Lastly, alerting police for non-emergencies contradicts the intended purpose of the emergency line, as 911 is designated for urgent situations requiring immediate attention, not for minor issues.
