How often these injuries happen
OSHA recorded 79 severe cases involving the ignition of nonpressurized vapors, gases, or liquids over the past decade. Thermal burns account for 73 percent of these incidents, often resulting in complex medical needs and extended recovery periods.
The intensity of these explosions often leads to permanent scarring and long-term disability, making it critical to identify the specific source of the ignition.

Explosions often occur when flammable residues inside nonpressurized containers are exposed to heat sources like cutting torches or electric ignitors. Petroleum and coal products are the primary source of these incidents, accounting for 22 percent of cases, and frequently ignite during routine maintenance or cleaning tasks. When you work with containers that are not properly purged or when ventilation fails to disperse flammable vapors, even a small spark can trigger a catastrophic event.
| 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 |

| 8 | Chemical burns, corrosions | 2 |
Where injuries happen most
Manufacturing accounts for 24 percent of these incidents, where the use of molten materials and industrial chemicals creates risk. Construction follows at 19 percent, as you may frequently encounter residual flammable gases in pipes or drums. In these sectors, failure to follow strict hazardous material handling protocols often leads to preventable explosions.
Real cases like yours
Common patterns in these incidents involve the ignition of residual vapors during cutting, welding, or cleaning operations. You are often injured when you assume a container is empty, only for trapped gases to react to tools or heat sources. If your injury occurred during a similar task involving flammable substances or containers, an attorney can help you review the specifics of your incident to determine if safety protocols were ignored.

| 2024 | GA | Construction | "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." | |
| 2024 | NJ | Construction | "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." | |
| 2024 | GA | Manufacturing | "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." | |
| 2024 | TX | Construction | "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.
