In addition to mutual aid, which is implemented during multiple incidents or incidents of a large scale, the Highland Park Fire Department also participates in automatic aid with all surrounding fire departments. Automatic aid provides for the closest units to immediately respond to reported fires regardless of jurisdictional boundaries. This provides the quickest response of manpower and equipment to incidents and allows more of the community to remain protected at all times.
As an example, automatic response occurs for an activated smoke detector (indicating a possible fire) in a business in the Braeside area. In this situation, personnel and equipment from the Ravinia Fire Station of the Highland Park Fire Department respond along with an engine from the Glencoe Fire Station, thus providing service from the closest resources and leaving the other Highland Park fire stations available for additional calls.
