TL;DR: If an active shooter targets your healthcare facility, follow the Run, Hide, Fight protocol to survive the immediate threat, then shift into mass casualty mode using START triage. Long-term recovery depends on trauma-informed mental health support, phased return to work, and ongoing active shooter training.
Violence in healthcare is no longer a rare headline. It’s a reality nurses face on ordinary shifts, in familiar hallways, surrounded by the people they care for. That’s why Elite Learning created its newest free download, A Nurse’s Guide to Navigating the Worst-Case Scenario. Inside, you’ll find practical, step-by-step guidance for five crises that could test everything you know.
Here, we’re previewing Scenario 3: an active shooter targets your facility. Below, you’ll find the short-term, medium-term, and long-term actions that can help you protect your patients—and yourself.

What does an active shooter scenario look like in a hospital?
Picture a Tuesday afternoon in the emergency department. While working on some charting, you hear three sharp pops, followed by screaming. A man with a handgun has entered through the ambulance bay, and he’s targeting people in scrubs.
Your training kicks in even as your hands shake. You help a patient into an exam room, lock the door, silence your phone, and wait. When law enforcement finally clears the area, the workplace you knew that morning is unrecognizable, and your shift is far from over.
This scenario feels extreme because it is. But preparation, not fear, is what gives you the power to act when seconds matter.
What should nurses do first during an active shooter event?
Your short-term priority is survival, using the Run, Hide, Fight protocol:
- Run (Avoid): If there’s a safe exit, evacuate. Leave belongings behind, help others if you can, and keep your hands visible so police know you’re unarmed. Once safe, call 911.
- Hide (Deny): Can’t escape? Block the door with heavy furniture, silence your phone, turn off the lights, and stay quiet. Spread out if you’re with others.
- Fight (Defend): As a last resort, defend yourself. Use items like fire extinguishers or IV poles, and work together to overpower the attacker.
While protecting yourself, protect your patients too. Shelter immobile patients in place by closing doors and pulling curtains. Give ambulatory patients quiet, clear instructions toward safety. Use simple language for pediatric and behavioral health patients and physically shield children if needed.
How do nurses respond in the hours after the threat ends?
Once the threat is neutralized, your role shifts to mass casualty response. This is the medium-term phase, and it’s demanding.
Coordinate closely with law enforcement, who will treat everyone as a potential threat at first. Share the facility layout, patient locations, and any remaining hazards. Then begin systematic triage using the START method (Simple Triage and Rapid Treatment):
- Immediate (Red): Life-threatening injuries like uncontrolled bleeding.
- Delayed (Yellow): Serious but stable injuries.
- Minor (Green): The “walking wounded.”
- Deceased (Black): Those with no signs of life.
To stay grounded under extreme pressure, try tactical box breathing. Inhale for 4 seconds, hold for 4, exhale for 4, hold for 4. Break overwhelming tasks into small checklists, and lean on your colleagues. Admitting you need a break is a sign of strength, not weakness.

How do nurses recover after surviving workplace violence?
Healing is the long-term work, and it doesn’t happen overnight. Watch for signs of post-traumatic stress in yourself and your peers, including hypervigilance, sleep problems, irritability, and the urge to avoid the workplace.
Accessible mental health resources are essential:
- Critical Incident Stress Debriefing (CISD): Held within 24–72 hours to help teams process the event together.
- Employee Assistance Programs (EAP): Offering confidential, self-paced counseling.
- Peer Support Groups: Safe spaces where staff can share their experiences.
Recovery also means rebuilding your sense of safety through evidence-based trauma therapy and a phased return to work. On a systems level, your employer should foster a culture where workers can report violence without fear of retaliation, backed by strong prevention plans and hands-on active shooter training.

Frequently asked questions
What is the Run, Hide, Fight protocol?
Run, Hide, Fight is the standard active shooter survival framework. First, evacuate if there’s a safe route. If you can’t, hide in a secured, blocked-off space. As an absolute last resort when your life is in imminent danger, fight back using any available items as makeshift weapons.
How should nurses triage patients after a shooting?
Nurses should use the START (Simple Triage and Rapid Treatment) method, sorting patients into four color-coded categories: Immediate (red), Delayed (yellow), Minor (green), and Deceased (black). Focusing on life-saving interventions like tourniquets helps achieve the greatest number of positive outcomes.
How common is violence in healthcare?
Violence in healthcare has become an increasingly serious concern for nurses and frontline staff. Because incidents can happen during ordinary shifts, preparation through training, prevention plans, and a culture of open reporting is critical to keeping staff and patients safe.
Where can nurses get mental health support after a traumatic event?
Nurses can access Critical Incident Stress Debriefing (CISD) within 24–72 hours, Employee Assistance Programs (EAP) for confidential counseling, and peer support groups. Long-term recovery may also involve evidence-based trauma therapy and a phased return to work.
