I'm not sure what exactly you are looking for, but I'll give you some more information specific to my team:
In order to be on our team you must meet these basic requirements: U.S. resident, county citizen, in good physical shape for what you plan on taking part in (no testing and "good" is subjective - we had a 300+ pound 5'8" guy who wa an expert in Horses and ATV's, but was... well, fat.), Basic First Aid/CPR, Low Angle Rope Rescue, ICS 100/200, and a clean NCIC background check. That may seem pretty basic, but since our team members all specialize in differnet areas, thats all we require for all people. Example: The year I joined, two others joined with me: One was a 55yo former rock climber with no background in rescue, but within that first year he took a ton of classes and certified as a Rope Rescue Technician and a Swiftwater Rescue Technician and was elected training officer for 2 years. The other was a 35yo soccer mom whose only asset was that she was a horseback rider and had her own horse. She is awesome and trained/volunteers for anything; ropes, helo, logistics. Of corse we love when team members join with massive amounts of ropes, water, medical, helo, search, dive, etc... training/certification, but the biggest assest any volunteer can have is the desire to volunteer and help. We have taken 18yo out of high school with no training and turned them into expert team leaders. However, all newbies are on probation for one year and can be canned at any time (they must also meet certain mission/training hour requirements that first year). I joined the team with just those basic requirements and my EMT (+ 4 years experience in EMS) and within the last ~4 years have trained and certified in Swiftwater Rescue, Search Management, ATV Rescue, Helos, Canines, and am now a Team Leader.
Now, our team is divided up into 10 sub-specialty-teams: Search, Technical (Ropes), Swiftwater/Flood, Dive, Nordic (Winter), OHV (ATV & Snowmobiles), Mounted, Air Ops, Medical, and Canine. All team members are required to be a member of at least 2 (Search and one other). If you meet that teams qualifications, then you can respond as a member of that team. For instance, I am a member of the Medical, Swiftwater, Canine, OHV, Technical, and Search, and am a support member for Air Opsl. I have little intereest in Horses, Dive, and Nordic. That said, when the pager goes off, no matter what the call, we all respond. It it is a Ropes call, and you are not on the Ropes Team, all that means is that we will not put you into the hot/warm zones. You will assist in the cold zone in some fashion. Since this thread comes from the Medical Srandpoint: In order to be on my Medical Team you have to have MFR or Higher (MFR, OEC, WFR, EMTB, WEMT, EMTP, RN, or MD). But if you are not a part of the ropes team, air ops, mounted, OHV, nordic, you are walking your a** into the patient. (I prefer the helo or ATV, myslef). We are BLS equiped only, but as said before have barrowed ALS supplies/people from ER/Ambulance if need be. We use any means to get to our goal asap. The basic run down on how we are dipatched is as follows:
911 gets called by either the victim or family/friends. Call gets turfed to the Sheriffs Office (who once again is responsible for all SAR in the county). The dispatcher takes all the info they can and calls the Deputy Liaision. These are paid SAR trained Deputies that rotate on-call weeks. Whatever deputy is on that week takes the call and determines if it is a SAR call. This is because many calls should either be fire dept calls, or can be handled by other (quicker) means than paging out the team. For instance: If we get a cell phone call form the vic who broke a leg in the middle of the wilderness and we know right where he is, we can call the Air Ambulacne, who can be on scen in 30 minutes wiht a MICP and MICN. Other times the call is handled by the deputy faster than mobilizing the team, or orest Serivice drives out to them, or it isn;t really an emergency that we can do anything for (well supplied, healthy group "stranded" on the otherside of a creek that will receed in 24 hours). If the deputy recognizes this as a SAR team call, he tells dispatch to page us. We all carry alpha-numeric pagers. Pages read: "All SAR memebrs (or a specific team) respond to the cache (or other place) for __________." We usually respond to the SAR Cahce, where we store the team gear/vehicles, get briefed, and respond according to the IC's commands. Now, this isn't always the case, which is why the deputies exist to detemine what course of action to take. Two completely different examples:
2 girls go over a waterfall about 1 hour from the closest town/ambulance. This is an emergenct rescue call. I just happened to be 25 minutes away and responded Code 2.5 in my POV becasue going to the Cache would have taken an extra hour. I (along with 2 other team members) get on scene 1.5 hours before the rest of Swiftwater Team can. We rescued one girl; the otehr died about 3 minutes before the 911 call went out. Had I been in town, I would have gone to the cache, preped the vehciles, and waited for a few others to show before we responded. FYI, a helo, the SAR Swiftwater Unit, 2 SAR trucks, 2 deputies, Forest Service, and 1 Fire Unit all responded, but we were the only ones equiped to perform Swiftwater Rescue.
60 year old female outdoor enthusiast walks away from camp to go meditate. BERKLEY LIBERAL! Seriously, the camp was run by UC Berkley. She fails to show for dinner, so at 2000 hours, the camp calls the SO. Hypotheticly, the deputy could have paged the team, and by the time we mobilized and got on scne it would have been midnight or latter (perhaps as late as 0200 hours). The area is not extreme, 4000 elevation, summer cool weather, she is an experiened adult outdoors person, no medical known medical issues, etc... Searching at night in teh conditions that area was in would have been futile, exhausting for the team who would have had to do it all nigh and day. The page went out to mobilize teh following morning at the Cache at 0600. We all got sleep, we had the time to secure additional resources (Mutual Aid Team, outside ATV's, outside dogs, and a helo), the team got briefed properly, we formulated a plan, and conducted a great search that resulted in a rescue.
The big thing you have to realize is that we are all volunteers who love what we do and cannot be experts in everything. We all have our own talents. Any prior training, certification, and experience you have is desirable. But every team has it's own requirements based on their area. i.e our neighbor to the south, Yosemite SAR requires all team members to be certified in Swiftwater and High Angle Ropes.
I know I ramble, but does any of that help? If not, keep asking for more specifics. B)
