Vapor and Gas Explosions at Work — Injury Statistics and Claims Information
Vapor and Gas Explosions at Work
Explosion incidents have increased by 125 percent
OSHA has recorded 79 severe incidents involving the explosion of nonpressurized vapors, gases, or liquids over the last decade. These events are predominantly characterized by thermal burns, which account for 73.4 percent of all reported injury natures.
The physical impact of these explosions is often widespread, with 55.8 percent of cases involving injuries to multiple body parts. Workers frequently suffer from deep tissue damage and long-term complications due to the intensity of the heat and pressure involved in these sudden releases.
What's Driving the Trend?
The 125 percent increase in incidents over the past ten years highlights a persistent failure to manage hazardous substances safely. Petroleum and coal products, along with flammable gases, remain the primary sources of these dangerous ignition events.
Manufacturing and construction industries account for 43.1 percent of all reported cases. These sectors often involve the handling of volatile materials in environments where ventilation and ignition source control are critical to worker safety.
Injury Types from Vapor and Gas Explosions
Top causes based on OSHA incident reports
Explosions often occur when flammable vapors accumulate in confined spaces or when workers interact with containers that previously held hazardous liquids. Common scenarios involve using cutting handtools on drums that still contain residual vapors or the accidental ignition of airborne paint or cleaning and polishing agents during routine maintenance.
| Injury Type | Incidents | |
|---|---|---|
| 1 | Thermal burns | 58 |
| 2 | Amputations, avulsions, enucleations | 4 |
| 3 | Fractures | 2 |
| 4 | Burns, corrosions, electrical injuries— unspecified | 2 |
| 5 | Severe wounds or internal injuries and other injuries | 2 |
| 6 | Traumatic injuries or exposures— unspecified | 2 |
| 7 | Surface and flesh wounds and other injuries | 2 |
| 8 | Chemical burns, corrosions | 2 |
Why This Matters for Your Case
Employers are legally required to mitigate explosion risks under 29 CFR 1910.106, which mandates strict controls for flammable liquids. Furthermore, 29 CFR 1910.119 requires comprehensive process safety management to prevent the unintended release of hazardous chemicals that could lead to fire or explosion.
Industries with Most Vapor and Gas Explosions
Where these injuries occur most frequently
Manufacturing leads all sectors with 24.1 percent of incidents, followed closely by construction at 19 percent. These industries frequently utilize high-heat processes and flammable chemicals, creating a high-risk environment where even minor procedural lapses can trigger a catastrophic explosion.
High-Risk Industries and Your Rights
In these high-risk sectors, employers must adhere to 29 CFR 1910.119 for process safety and 29 CFR 1926.152 for fire protection in construction. These regulations demand rigorous training, proper equipment maintenance, and the implementation of safety protocols to prevent the ignition of flammable materials.
Real Incident Reports
From actual OSHA investigation files
The reported incidents consistently reveal a pattern of failure to properly purge containers of flammable residue before applying heat or sparks. Many workers are injured while performing routine maintenance or cleaning tasks, often because the presence of invisible, explosive vapors was not identified or mitigated before work commenced.
"An employee was cutting glass for a custom windshield and was using denatured alcohol during the cutting process. The denatured alcohol caught fire and the flame traveled to a gallon-sized container of the liquid. The can exploded and the employee sustained second- and third-degree burns from the waist up. "
"On April 18, 2025, an employee was cutting the lid off an empty 55-gallon drum using a plasma cutter. The drum originally contained a flammable liquid and residual liquid inside the drum ignited and exploded. The employee was hospitalized with burns to the face, chest, and arms."
"An employee was painting the inside of a new parts-cleaning machine for electric motors and motor parts when the airborne paint exploded and burned the employee. The employee sustained burns to their neck, lower forearms, and hands."
"On March 7, 2025, at 11:24 a.m., an employee was in a customer's basement working to light a water heater using an electric starter on the appliance. The employee pushed the ignitor when an explosion occurred, resulting in first- and second-degree burns on the face and neck as well as second- and third-degree burns on both hands."
"An employee was operating a mold machine when a pouring ladle that was coated with a water-based paste was submerged in molten aluminum. The moisture caused an explosion, resulting in severe burns over his body."
"An employee had used cleaning solvent to clean the engine room. The employee turned on a vacuum, which caused an explosion to occur, followed by a fire. The employee was hospitalized with second-degree burns."
"Two employees were tack welding over a hole in a diesel tank. Diesel in the tank exploded. One employee suffered burns to the face; the other suffered severe burns over 40 percent of the back, shoulder, and arms."
"An underground crew was opening up a manhole for a visual inspection. Natural gas was leaking in the manhole. As they began to slide the cover off, a flash occurred when the leaking natural gas mixed with oxygen, creating a combustible environment. One employee was hospitalized."
"On September 11, 2024, an employee was attempting to remove a valve from an empty 55-gallon drum that had contained ethanol. The valve was stuck to the lower adapter ring. The employee tack welded the rings together to remove the entire valve when the drum exploded and the employee sustained burns and contusions."
"Three employees were removing a cover from an oil well storage tank. Some of the bolts were corroded, so the employees used an electric grinder to remove the bolts. Sparks from the grinding wheel ignited liquid/fumes inside the tank, causing the tank to explode. One employee received severe burns to over 70% of their body."
