Amid the widespread misuse of ambulances in situations that are not strictly emergencies, the Fire and Disaster Management Agency will soon introduce an easy-to-use tool to help judge whether a person's condition is serious enough to merit calling one.

The agency will launch a website and a smartphone app around the end of this month that will help people quickly find out whether one's condition requires emergency transport or is stable enough that they can visit the hospital by themselves.

"The average person might struggle with assessing whether he or she needs emergency transport" or should wait a while and observe their symptoms, an agency official said.
