Final answer:
During a disaster, emergency responders may be sent to other districts in the county, even if it leaves their own district without proper staffing.
Step-by-step explanation:
In the event that the entire EMS system is in disaster mode, it is possible for emergency responders to be sent to other districts in the county, even if it means leaving their own district without sufficient staffing. This is true because during a disaster, the priority is to provide assistance to as many people as possible, regardless of district boundaries.
