      I’ve been involved in EMS since I was 18 years old. I have never heard of anything being classified as ‘George’. I have only heard of Alpha, Bravo, Charlie, Delta, Echo, and Omega.

        Just got that question answered by Arvada Fire Department. Anything after the number is additional information like the location of the patient. And for reports.
