A decade of increasing fire hazards
OSHA recorded 64 severe incidents involving fire and thermal exposure, with thermal burns accounting for 81.2 percent of all reported cases. These injuries often require extensive hospitalization and specialized care for deep tissue damage.
The impact of these fires frequently extends beyond skin burns, as 8.5 percent of cases involve systemic body injuries. Workers often face long-term respiratory complications from toxic smoke exposure, particularly when fire suppression efforts go wrong.
The 900 percent increase in reported cases since 2015 highlights a growing failure in fire prevention and safety training. Heating and cooking machinery, along with improper handling of debris and nonpressurized containers, remain the primary sources of these dangerous events.
Manufacturing and construction industries lead in incident frequency, accounting for over 50 percent of all reports. These environments often involve high-energy electrical systems and flammable materials that require strict adherence to fire safety protocols.
Top causes based on OSHA incident reports
Workplace fires often stem from the misuse of heating equipment, improper disposal of flammable debris, and failures in electrical maintenance. Workers are frequently injured while attempting to extinguish small fires using inadequate equipment or when chemical reactions from fire suppressants cause respiratory distress.
| Injury Type | Incidents | |
|---|---|---|
| 1 | Thermal burns | 52 |
| 2 | Effects of poison, toxic, or allergenic exposure— unspecified | 6 |
| 3 | Poison, toxic, or allergenic effects— other respiratory | 2 |
| 4 | Poisoning, poisoning-related asphyxia | 2 |
| 5 | Severe wounds or internal injuries and other injuries | 1 |
| 6 | Intracranial Injuries | 1 |
Employers are legally mandated to provide a safe environment under 29 CFR 1910.157, which dictates the requirements for portable fire extinguishers and employee training. Failure to maintain electrical panels or provide proper fire suppression equipment constitutes a violation of 29 CFR 1910.303, which governs the installation and maintenance of electrical systems.
Where these injuries occur most frequently
Manufacturing accounts for 34.4 percent of all fire-related severe injuries, followed by construction at 15.6 percent. These sectors involve high-heat processes and complex electrical infrastructure that, if not properly managed, create immediate fire risks for employees.
In high-risk industries, employers must comply with 29 CFR 1910.38 to ensure a clear emergency action plan is in place. Furthermore, 29 CFR 1910.155 requires that fire protection systems are maintained in reliable operating condition to prevent the exact scenarios that lead to severe burns and respiratory injuries.
From actual OSHA investigation files
Recent incident reports reveal a recurring pattern where employees suffer severe burns or respiratory damage while attempting to manage small-scale fires without adequate training or personal protective equipment. These accounts frequently involve electrical panel fires, the use of accelerants for debris burning, and adverse reactions to fire suppression chemicals.
"An employee was outside, participating in fire extinguisher training onsite. She extinguished a fire and then the chemical from the fire got in her face. She started coughing and was hospitalized with trouble breathing."
"An employee was working on installing tubing to run electrical wiring to the other side of a building. The employee noticed smoke coming from the electrical panel and went to shut off the breaker. The electrical panel was on fire and the employee sustained burns to their right hand."
"An employee was performing a controlled burn of brush at the end of a drainage pump using gasoline. The fire spread and the employee suffered burns to the legs and hands."
"An employee was using gasoline to start a fire on some wood debris and suffered burns to their right hand and forearm, resulting in hospitalization."
"An employee was extinguishing a small ion battery fire when they began to have breathing issues, resulting in hospitalization."
"An employee was in a patient's room when a small electrical fire started. They were assisting with the fire and were exposed to smoke inhalation, resulting in hospitalization."
"An employee was using a torch to cut temporary support fasteners (steel bolts) on a concrete floor. Material on the floor ignited and the employee sustained burns to both hands and their right knee."
"An employee was burning cardboard boxes. He poured a flammable chemical on the boxes, and then his clothes caught on fire. The employee was hospitalized with second- and third-degree burns to 33% of his body."
"An employee was unplugging an extension cord from an outlet when it began to spark and ignited, resulting in burns to their right hand."
"On October 17, 2025, at approximately 12:17 PM, an employee was standing in front of the grill with the green cutting board in his hand. As he moved to the right, he jostled the pan of butter which dripped onto the back of the grill causing it to flame up. At this point his vape pen combusted and exploded upwards into the metal ceiling causing a cylinder-shaped indentation. The employee's chef coat caught on fire, resulting in first- and second-degree burns to his forearms as well as burns to his mouth, nose, and hands. "
