Douglas County Emergency Management will direct a hazardous materials exercise Tuesday, and agencies in 19 counties will participate.

Bob Newton, an emergency management spokesman, said it is part of a grant that involves a full-scale exercise in Douglas County during which law enforcement, fire and medical units will respond. Lawrence Memorial Hospital also will practice patient decontamination.

Other functional exercises will occur in Geary, Franklin and Jefferson counties. Tabletop exercise will take place in 15 other northeast Kansas counties.

The exercise, “Operation Luminous Sunflower,” will give agencies an opportunity to respond and coordinate on issues to practice for a real incident, Newton said.
