Rescue workers and D-MOR, or disaster mortician teams, spray identifying codes in brightly colored spray paint on doors in flood zones. The "X" means a search has taken place. Date and time of search are also noted; "LB" with a number indicates number of living bodies encountered; "DB" with a number indicates the number of dead bodies. The teams carry GPS devices to identify and note the locations they've inspected.
