A series of severe storms leaves scores of home flooded on Chicago's southwest side.  The temperatures are expected to get into the teens overnight and hundreds of people are without power or heat due to the flooding.

¶               

Chicago Fire and Police Departments have recently arrived on scene and are already being overwhelmed by the number of people.  They have special need for additional resources to care for victims with medical issues. The Chicago Office of Emergency Management and Communications (OEMC) is asked to find more volunteers, and the office looks to the Community Emergency Response Team.

¶              

The CERT coordinator at OEMC brings up the Sahana module and creates two new events:  "12/05/2011 Flood, Southside: General" and "12/05/2011 Flood, Southside: Medical".

¶              

She then sends two deployment requests.  The first goes to all active volunteers on the "Emergency Response" mailing list and requests help for logistics, moving, crowd and traffic control.  For the second, she filters the recipient list by Medical Qualification and sends a deployment for a team of medically-trained volunteers.

¶              

The system sends out the deployment requests and processes the replies.  Each volunteer willing to be deployed is automatically sent details on where to go and to whom to report.  The general deployment volunteers report to the OEMC Incident Commander while the medical deployment is sent to the on-scene Medical Director. 

¶              

Both the OEMC IC and the Medical Director receive an automated link to a roster of their volunteers, including picture and qualifications.  When the volunteers arrive they are sent to where they're needed.
