The Indiana Department of Homeland Security (IDHS) leads Indiana's emergency planning and operations, first responder training and fire and building safety. The Indiana State Fire Marshal leads the Division of Fire and Building Safety (within IDHS), which oversees the enforcement of building codes and includes a fire investigations unit. The agency certifies and trains thousands of first responders and also hosts state-level exercises each year. IDHS also supports the state Emergency Operations Center (EOC), which leads response and coordination efforts for large-magnitude incidents.
