Your counter point 1, I did not refer to the federal goverment in any way. Somehow I do believe(maybe not) they are involved because of "Homeland Security"
Your counter point 2, I did not refer to to patrol as being a "private security force", I did refer to a "private business" being able to employ any security force they felt appropriate to deal with any issues they have for their "private area". "using Pro or Volunteer". I probably should have been a little clearer, I believe some "Private ski areas" rely on the Patrol to provide all security - The area I patrol does not use the patrol in this manner. They employ off duty police officers, the ski patrol only serves as a "First Responder certified as a OEC Tech" to a medical emergency. We do however have Physicans, Nurses, Paramedic's and EMTs as members of the patrol; however when they respond to an emergency at the ski area, They respond as a First Responder certified as a OEC Tech. (Insurance reasons, I am told)
Your counter point 3, Well spoken, Ambulance's generally responding to the ski area where I patrol are "public service''- same as the Fire Dept. and the Police Dept. Although, there are "private ambulances" as well as "air ambulances which are part of private hospitals" operating in this area also, they do not however respond to 911 calls, unless specifically requested.
Your point 3 brings in the issues of having different states with different standards for different services(private vs public) trying to certify a organization that serves in multiple states, and some ski areas (as previously pointed out in this thread) have bountry's in different states.
I also would like to point out the ski area where I patrol does not bound multi states, however it is very close to a state line, which in many cases causes the responding EMS service issues when they are requested by the patient(non-life threatening) to be transported to a hospital in a different state.
As far as you wondering which direction I am coming from - some states use the DOT to certify the EMS (interesting) some states use other sources. If you are suggesting standardizing the EMS service - ok I guess I am not suggesting this at all, but I am recognizing the National Ski Patrol is a national organization providing a "First Responder to a medical emergency" where it fits a ski/rec area needs.
