Resistive Heating Origin and Cause Uncovered
Blaze Fire Investigation is now known as Anderson Engineering. (updated 6/28/17)
A Blaze Fire Investigator is called to the scene of an apartment fire. The area is nearly knee deep in debris and objects have been moved around, changing the scene. There is a clear fire pattern observed on a wall, pointing to the floor. A sofa is burned on one side and a window air conditioning unit is visibly melted.
This investigation needed to begin with an interview with the tenant. With his home unlivable because of the fire, he was not easy to find but when located through a relative, he was cooperative. The tenant was able to visually recreate the room and the placement of furniture that had been disturbed during the course of the fire fight. Although one would assume that the air conditioner would not be used on a cool day, the tenant was able to share that because the multi-family building was usually warm, that he did, in fact, leave the air conditioner on while he left to go to an appointment.
Our investigator carefully sifted through the debris and discovered a fire pattern from the window pointing away from the wall. While the window air conditioner exhibited damage on its exterior, it did not appear to have damage that emanated from within the unit. There were badly damaged extension cords and a power strip with numerous inputs on the floor.
In consultation with forensic engineering colleagues at Anderson Engineering of New Prague, our investigator was able to determine that the origin of the fire was one of the extension cords and the cause was resistive heating, or too much power traveling through the cord.
THE RESULT FOR OUR CLIENT:
Because of skillful interviewing, detailed analysis of the scene, and collaboration with in-house forensic specialists, Blaze Fire was successful in uncovering the origin and cause of this apartment fire, and the client was able to confidently determine their path to recovery.
