MURFREESBORO, Tenn. (WGNS News) - Firefighters responded to a construction-site equipment fire involving a Komatsu excavator, where smoke could be seen rising from the large machine as crews worked to bring the blaze under control. The incident occurred on Tuesday morning, off of Franklin Road (Hwy 96) in Murfreesboro.
At the scene, firefighters in full protective gear worked to douse the flames coming from the tracked excavator, after carrying their hose lines from the truck to the fire. Hose lines could be seen stretched across the dirt worksite. Smoke appeared to be coming from the cab and engine area of the machine, which was positioned near piles of cleared brush and debris.
The fire created a challenging response environment because of the size of the machinery, the heat generated by heavy-duty equipment, and the amount of combustible material nearby. Crews worked from multiple angles, including around the cab, engine compartment, and rear housing of the excavator, to cool hot spots and prevent flames from spreading into the surrounding brush.
The good news from the scene is that no injuries were reported. The financial impact, however, can be significant. Beyond the cost of replacing or repairing the damaged machine, the loss of heavy equipment can also create expensive delays when that piece of machinery is needed to keep a construction project on schedule. No additional details were immediately available regarding the cause of the fire, or the total dollar loss.
According to research, fires involving heavy construction machinery often begins for several reasons, including mechanical failure, electrical problems, leaking hydraulic fluid, fuel-related issues, or debris collecting near hot engine components. However, those are just a few of the more common reasons as to what leads to fires on construction sites. The official cause of the fire has not yet been released.

While fires involving large machinery are not as common as passenger vehicle fires, they are a recognized category in national fire reporting. The National Fire Incident Reporting System uses Incident Type 138 for “off-road vehicle or heavy equipment fire,” a category that includes earth-moving equipment, bulldozers, farm machinery, dirt bikes, and other specialty off-road vehicles.

Nationally, the Insurance Information Institute reports that fire departments responded to an estimated 1,388,000 fires in 2024, which was the most recent year for national data on fires to be publicly released by the organization. The fires in the statistics caused more than $19 billion in direct property damage. That figure includes losses to structures, vehicles, machinery, vegetation, and other property involved in fires. Of that total, vehicle fires accounted for an estimated 211,500 incidents and nearly $2.8 billion in direct property damage. The “other vehicle fire” category, which includes non-highway vehicles, accounted for an estimated 33,000 fires and $628 million in losses.
In Tennessee, the State Fire Marshal’s Office reported 24,269 total fires in 2025, with an estimated $478.6 million in property loss statewide. Tennessee law also requires fire departments to report every fire within their jurisdiction within 10 days of the incident.

Industry sources note that fires involving construction and industrial equipment can be especially costly because the loss is often larger than the machine itself. A damaged excavator, dozer, loader, or skid steer can delay site work, interrupt contracts, increase insurance costs, and require expensive replacement or rental equipment while the original unit is repaired or written off.
Fire officials often encourage contractors and equipment operators to reduce risk through regular maintenance, daily walk-around inspections, cleaning debris from engine compartments, checking hydraulic and fuel lines, watching for electrical issues, and keeping properly rated extinguishers or suppression systems available on job sites.

While it may be hard to believe by looking at heavy duty construction equipment, the harsh conditions in which they serve can easily become a fire hazard when heat, fuel, hydraulic systems, electrical components, and dry debris come together in the wrong place at the wrong time.
