4-06 Box, 14:48 - Ridge VFD was dispatched to the 48600 block of Fox Harbor Road in Ridge for the reported house on fire. Captain 4 arrived at 14:51 on Engine 41 and reported nothing evident from the 360 investigation. Construction workers reported that they witnessed a large amount of smoke coming from under the floor of the electrical room and began hosing the area and called 911. On arrival, 41’s interior crew confirmed light smoke coming from the crawl space under the electrical room. Tankers 4 and 44 and Engine 141 arrived and crews assisted with investigations and water supply. Chief 4 arrived at 15:01 and assumed command. Chief 4 held all Company 4 units and Engine 141; mutual aid units were placed in service. With the crawl space area being inaccessible, crews had to cut a hole in the side of the house to gain access. Smoke and burned insulation were discovered. Following suppression and overhaul efforts, faulty, melted wiring was found and believed to be the culprit. After a thorough overhaul, units went in service at 16:28.
