Conducting a full-scale exercise involves much more than just responding to a simulated incident. Substantial planning involving all stakeholders sets the tone for the entire project. A fully scripted, realistic scenario gives participating agencies the sense of a real world incident. Thoughtful identification of key evaluation points, including detailed job aids for exercise evaluators, along with a thorough, constructive after-action review, produces positive results that are beneficial to all participants. Join us as we go behind the scenes of a full-scale hazardous materials response exercise at Kyle Field on the campus of Texas A&M University.
