AH! ok ok ! ^_^
In Italy the 911 is "118". When you call 118 thy give to local Red Cross ( or private ambulance association) a code.
Green - Yellow - Red
GREEN CODE
Competence of volunteer (as me). Training of 120 Hours and 3 exams + 100 hours as 4th member in ambulance and 3 exams.
We are "Volunteer of Rescue" (Volontari del Soccorso)
We are allowed to use all "trauma" equipment (don't know the specific name in english

), we are abilitated on BLS and DAE (semi-automatic defibrillator), we can't somministrate nothing without a medic on site.
Yellow and Red code
The amblance equip is composed by: 2 volunteer (driver and assistent) 1 medic and 1 paramedic.
The volunteer of green and red code are the same, the only difference is the medic and paramedic on board.
In my Red Cross Station we have 1 advanced Ambulance (yellow and red) + 2 Basic Ambulance (green) H24 365 day.
Example of code...? A car accident, 3 hurt people with all vital funcion. 2 of them embedded and bleeding... this is a green code
The same crash with a people inconscios is a yellow-red
You can imagin, there are 80% green code, we must be able to be risolutive on target...
