MABAS is an acronym for Mutual Aid Box Alarm System. MABAS offers a statewide mutual aid response system for fire, EMS and specialized incident operational teams. Sharing the effort are representatives from the Office of the State Fire Marshal, Department of Public Health – EMS Division and Illinois Fire Chiefs Association. The system defines a resource response plan to any location within the state when the Governor orders a Declaration of Disaster. In short, to all of the first responders on the front lines and keeping Illinois safe –we GOT YOUR BACK!
