The Lisle-Woodridge Fire Protection District’s Fire Investigation Unit is committed to its Mission Statement "Upholding the Legal Responsibility as Outlined in State Statutes for Determination of the Cause and Origin of Each Fire". Through the dedication, education and experience of each investigator, our mission is achieved. This is what makes our Fire Investigation Unit team successful.

The concept of the Fire Investigation Unit is not only to investigate after an incident occurs but, also, to take a pro-active stance before an incident happens. Through pre-planning, product information recall/safety notices, tracking, surveillance and various other methods, this pro-active stance benefits our community in the area of fire prevention.
