Dozers are commonly used on vegetation fires, but it is unusual to see them at a structure fire. In the video above, Los Angeles County Fire Department used a dozer to assist firefighters during the overhaul or mop up stage of a structure fire in Lancaster, California Thursday night. Apparently there was a large quantity of material inside the commercial building that would have been difficult to completely extinguish without spreading out the burning debris. It looks like they were using foam or a wetting agent in the water to achieve greater penetration.
