Severe equipment fire incidents are trending upward
Over the past ten years, OSHA has recorded 205 severe incidents involving vehicle and machinery fires. These events frequently result in thermal burns, which represent 78.4% of the reported injury types in this category.
The severity of these fires is reflected in the high frequency of injuries to multiple body parts, which account for 51.5% of all reported cases. Workers often face life-altering consequences, including extensive skin grafts and long-term recovery from deep tissue damage.
The frequency of these incidents has increased by 100.0% over the last decade, with a particularly sharp 116.7% rise in the last five years alone. This growth is largely driven by failures in maintaining heavy equipment, such as trucks and industrial hauling vehicles, which remain the primary sources of ignition.
Manufacturing and mining industries report the highest volume of fire-related injuries, accounting for 26.3% and 18.0% of cases respectively. These environments often involve high-heat processes and the storage of flammable materials, creating conditions where a single mechanical failure can lead to a catastrophic fire.
Top causes based on OSHA incident reports
Equipment fires typically stem from the intersection of high-heat mechanical components and flammable substances. Common scenarios include hydraulic line ruptures that spray fluid onto hot engine manifolds, or refueling accidents where gasoline vapors ignite upon contact with a hot exhaust system. These incidents frequently involve trucks, mining machinery, and industrial material hauling vehicles that are not properly inspected for leaks or heat-shield integrity.

Employers are legally obligated to mitigate fire risks under 29 CFR 1910.157, which mandates the provision and maintenance of fire extinguishers, and 29 CFR 1910.106, which governs the safe handling of flammable and combustible liquids. Failure to maintain equipment or provide adequate fire suppression systems constitutes a direct violation of these federal safety standards.
Where these injuries occur most frequently
Manufacturing leads all sectors with 26.3% of reported fire incidents, followed closely by mining at 18.0%. In these industries, the constant operation of heavy machinery and the proximity of workers to high-pressure hydraulic systems create a persistent risk of fire that requires rigorous preventative maintenance.
In high-risk sectors like manufacturing and mining, employers must adhere to 29 CFR 1910.157 for fire protection and 29 CFR 1910.132 for personal protective equipment requirements. These regulations demand that employers identify fire hazards, provide appropriate training for refueling and maintenance, and ensure that fire suppression equipment is accessible and functional at all times.
From actual OSHA investigation files
Reported incidents reveal a recurring pattern of equipment failure and unsafe refueling practices. Many cases involve hydraulic line ruptures or the ignition of fuel during routine maintenance, often resulting in severe thermal burns to the hands, thighs, and abdomen. These narratives highlight how quickly a mechanical spark can escalate into a life-threatening emergency when fire safety protocols are ignored.
"An employee was operating the scraper when a hydraulic line ruptured and created a flame. The employee jumped off the equipment and broke a leg."
"Three employees were servicing and cleaning an oil well when a fire occurred. All three employees were burned. One employee was treated and released. Two employees were hospitalized and one hospitalized employee required surgery."
"On July 18, 2025, a light-equipment operator was using a pressure washer to remove cementitious material buildup from the internal wall of a tremie pipe. The operator was refueling the pressure washer using a 5-gallon gas can. The equipment's engine and exhaust were still hot and the gasoline ignited. Flames spread to the pressure washer skid, a nearby fire extinguisher, and the operator s clothing. The operator sustained second-degree burns to approximately 35% of their body including their hands, lower abdominal area, upper thighs, and knees. The employee was hospitalized."
"An employee was refueling a commercial-grade riding lawn mower. As he was refilling the tank, the gasoline splashed onto the muffler, which sparked and caught fire. The employee suffered burns to both thighs and the left side of his abdomen."
"An employee was removing burning material from a machine. While being used to extinguish a fire, the diffuser/horn of a fire extinguisher disconnected from the hose and the hose struck the employee's neck, back, side, and shoulder. The employee sustained a closed fracture of thyroid cartilage and a vertebral artery occlusion."
"Employee 1 was operating a crane to move a pumping unit. Employee 2 was holding a tag line. The crane lifted the pumping unit and began rotating clockwise to place it on top of a concrete base. The front driver s side outrigger and float began to sink into the ground, causing the crane to lean over. This caused the pumping unit to swing and strike into an adjacent wellhead, breaking some piping and causing a fire. The crane then fell over and it's boom broke piping on a second wellhead, contributing further to the fire. Employee 1 fell out of the cab and crawled out of the fire. He sustained burns to his face and hands and had fractured ribs. He was hospitalized. Employee 2 was burned on his cheek, arm, and leg."
"An employee was repairing a forklift at a customer site when there was a flash fire (blowback from the throttle body), that burned their right forearm."
"An employee was doing brazing work on a copper line, part of a commercial refrigeration unit that was charged with propane. A blockage in one of the tubes resulted in a flame blowback. The employee suffered second-degree burns to the left side of the face and neck area. They were hospitalized, requiring surgery."
"An employee was starting a large ventilation blower. Fire/gasoline shot out of the blower and burned his left shoulder and underarm."
"An employee was using a saw to make cuts into concrete masonry units. The saw caught fire, which caused the employee to drop the saw and the gas cap broke. The gas spilled partially onto the employee and the fire spread to their clothing. The employee suffered burns to the waist area and was hospitalized. "
