Which category accounts for the largest share of On Duty Firefighter Deaths?

• A. Firegrounds
• B. Responding/Returning
• C. Normal Station Duty
• D. EMS

Answer: (A)

The most dangerous setting for on‑duty firefighters is the fireground during active firefighting. On the fireground, conditions can deteriorate quickly—extreme heat, dense smoke, limited visibility, and the risk of structural collapse or backdrafts create the highest chance of fatal injuries. Fire attack, search, rescue, and ventilation put crews in close proximity to the fire and to each other, where a single changing factor can lead to a life‑threatening situation. That combination of unpredictable, high‑risk conditions explains why the fireground accounts for the largest share of on‑duty firefighter deaths.

In contrast, while responding/returning and working at the station or performing EMS tasks involve real hazards, the per‑incident risk on the fireground tends to be greater, which is why it stands out as the leading category in fatal incidents.
