RAMPART is the nickname given to the clinic operated by the BMORG contractor at burningman. Currently it is Humboldt General Hospital from Winnemucca Nevada. They were looking for emt's and RN's pre event 2012 and I do not know if they use volunteers.
http://www.hghemsmedstaff.com/The field personnel you see wearing yellow shirts on the various units are ESD (Emergency Services Department) volunteers that volunteer directly with BMAN. Our stations are located at the 3'oclock and 9'oclock streets. You can get more information for ESD here
http://www.brcesd.org/ ESD provides EMS, Fire, Mental Health Services and more. Staffed by professionals from every aspect of emergency management as well as surgeons, MD's, RN's, Firefighters and Communications.
ESD also staffs the major burns - temple, man, art burns etc with an IC and a rapid intervention team as well as safety. This was year 7 for me with ESD and I am having a blast. Many FF's and emergency personnel fell burned out in the default world, but when you respond to a call at BM or help a walk in patient it is a completely different vibe and many find it relaxing over the default clinical type of response. FIll out the volunteer form at ESD if your interested, I do not know how to volunteer for Humboldt General for their "RAMPART" station on the esplanade at about 530.
Hope this helps.
