Pridemark QRV's are not staffed often, especially at night. In Arvada if you hear Sierra 5 or 6, they are a team leader and may likely be in the qrv, but not always. In boulder, Pridemark 20 or 21 are team leaders and may occasionally be in a qrv, but they're likely on an ambulance. There are supervisors and managers though that can jump into a qrv if it is around. There is no set number for the qrv's though.
jfab said:Are you familiar with Pridemark at all? If so, I believe EMS units are simalar to Pridemarks QRV's(Quick Response Vehicle). They can either provide extra assistance/supplies on scene, or can restock an ambulance at the hospital. North Metro Fire has these as well. I'm sure other departments have them, I'm just familiar with North Metro and Pridemark.
BTW, North Metro's is ID'd on the Radio as EMS 61, and I'm not sure about Pridemarks QRV's.
Hope this helps!
