Simulated plane crash drills Humboldt County mass-casualty response at Murray Field

Sirens echoed through parts of Eureka as Providence St. Joseph Hospital and local emergency crews worked through a simulated plane crash at Murray Field, turning a high-stress morning into a test of whether Humboldt County could handle dozens of badly injured patients at once.

The annual hospital-wide drill brought together Providence staff, Humboldt Bay Fire, City Ambulance of Eureka and other partners to practice the first, most critical steps in a true disaster: who is treated first, where patients are sent, and how the system holds together when the number of victims quickly overwhelms normal routines. Roughly 40 Fortuna High School students volunteered as mock victims, giving responders a scene that looked crowded and chaotic instead of orderly and scripted.

This year’s exercise also included hazardous-materials decontamination and a hospital decontamination corridor, a reminder that a major crash or other mass-casualty event could involve more than blunt trauma alone. Humboldt Bay Fire Chief Timothy Citro said the scenario was built to include that layer of response, because crews may have to strip away contamination before patients can even enter the hospital.

Inside the hospital, the drill tested triage decisions, operating room readiness and the ability to pull in additional clinicians when the patient load rises fast. Trauma Program Manager Brandon Klith said the exercise is intentionally kept partly secret from staff so Providence can see how its policies and procedures perform in real time rather than in a rehearsed tabletop setting.

That pressure matters in Humboldt County, where Providence says St. Joseph Hospital has served the community since 1920 and is the county’s highest-level trauma center. The emergency department is designated a Level III Trauma Center by North Coast Emergency Medical Services and is also EDAP-certified for children 14 and under. Providence said the latest trauma designation renewal lasts three more years, and that EMS uses those designations when minutes count and patients need to be moved to the right facility.

The hospital is also Humboldt County’s largest, and Providence says the next closest higher-level trauma center is more than three hours away. That distance makes local surge planning essential, especially when the trauma program cared for about 680 injured patients in the prior year referenced by Providence, with more than half arriving as trauma-team activations. Providence also said later emergency-department improvements helped patients get seen within ten minutes of arrival, underscoring how day-to-day speed and disaster preparedness are tied together.

A similar multi-casualty drill in May 2025 used 30 Fortuna High School students and a school-bus-crash scenario. Together, the exercises show a region treating mass-casualty readiness as a recurring necessity, not a one-time demonstration.
