Providence Hood River’s Emergency Department will hold a mass casualty drill on July 31 at Jackson Park.  The scenario will be a bus crash involving adolescents, made up with fake wounds and blood.  Elements of the drill will include triage, trauma team response, hospital command center activation, and first responder participation.  Emergency vehicles will transport the kids to the hospital’s emergency room.  Hospital spokesperson Susan Frost says they are trying to get the word out to the community the drill will take place to avoid people seeing it and thinking that it is a real accident, and spreading misinformation on social media.  The mass casualty drill will take place on July 31 at 10 a.m.
