Inhalation of harmful substances is the primary cause of these injuries, representing 57% of all reported incidents. These events often occur when you are exposed to toxic fumes, gases, or chemical vapors in poorly ventilated areas or during the handling of experimental substances. Equipment failures, such as leaking vehicle exhaust systems or malfunctioning chemical containment units, frequently create environments where you are unknowingly exposed to life-threatening concentrations of toxins.
| Cause | Incidents | |
|---|---|---|
| 1 | Inhalation of harmful substance | 21 |
| 2 | Fire— unspecified | 3 |
| 3 | Vehicle or machinery fire | 3 |
| 4 | Bitten or stung by animal | 2 |
| 5 | Fire— small-scale, limited | 2 |
| 6 | Exposure to harmful substance—multiple routes of exposure | 2 |
| 7 | Nonroadway noncollision incident | 1 |
| 8 | Exposure to harmful substance through exposed tissue | 1 |
Where injuries happen most
Manufacturing accounts for 22% of all severe poisoning and asphyxia cases, driven by the complex chemical processes and industrial machinery used in daily production. Administrative services and health care also show significant risk, often due to exposure to hazardous materials or faulty ventilation systems in your workspace.
Real cases like yours
Recurring patterns in these reports show that incidents often stem from inadequate ventilation during chemical synthesis, vehicle exhaust leaks in confined spaces, or accidental exposure to hazardous substances during routine inspections. If any of these scenarios sound like what happened to you, an attorney can help you review the specifics of your incident to determine if your employer failed to provide a safe working environment.
