Power failure in a healthcare setting is more than a nuisance. It’s a test of systems, people, and calm decision-making. In ATI Skills Modules 3.0, the Safety Video resource walks through what to do when the lights flicker and then go dark. The core takeaway is clear: activate emergency power systems and ensure patient safety. Let me explain why that is the cornerstone of a solid response—and how it translates into real-world practice.

Why emergency power matters more than you might think

Imagine this: a patient on a life-support device, a nurse monitoring vital signs on a wall-mounted screen, corridors lit softly enough to guide folks to safety. A hospital isn’t just a building; it’s a network of dependences. When power fails, a cascade can begin quickly. Critical equipment must stay powered, because even a few minutes without life-support capabilities or critical monitoring can have serious consequences.

That’s where emergency power systems come in. These aren’t decorative backups; they’re the backbone that keeps essential care going. An automatic transfer switch detects the outage and shifts the load from the utility grid to a generator. The generator then powers priority areas and devices—life-support machines, patient monitors, lights in patient care zones, and essential infrastructure like air filtration and heating or cooling. This isn’t about luxury lighting; it’s about preserving patient safety and the clinicians’ ability to do their jobs without frantically chasing down power in the middle of a crisis.

What to do the moment the power fails

Let’s get practical. The immediate response is a sequence, not a free-for-all. The goal is simple: keep patients safe and stabilize the environment while the power system comes back online or a safe contingency plan kicks in.

• Confirm the outage and switch to emergency power

• If you’re trained to do so, ensure the facility’s emergency power system starts automatically. If you’re part of a team with responsibilities, your role is to verify that critical zones have power. This is about reliability; you want to confirm the generators are running and the automatic transfer switch has re-routed power to essential loads.

• Check that life-support devices, ventilators, infusion pumps, monitors, and essential lighting are connected to essential circuits. If a device isn’t on a protected circuit, address it quickly with the on-call engineer or supervisor.

• Prioritize patient safety above all

• Maintain airway and respiration safety for patients who rely on electrical support. Ensure ventilators or monitor alarms remain audible and visible. Keep corridors lit enough to navigate safely, and ensure that fall risks are managed.

• Don’t rush to move every patient. Evacuation should be a deliberate, state-issued decision based on the status of power, the availability of backup lighting, and the location of patients. The default is to keep patients where they are, under supervision, unless movement is necessary for safety.

• Communicate clearly and assign roles

• A quick, calm briefing helps. Tell the team which zones are powered, which devices are critical, and who is responsible for monitoring the generator status. Clear communication reduces chaos and keeps everyone aligned.

• Establish a simple incident command or point person if your facility uses one. Even a short, organized check-in helps everyone stay on the same page.

• Verify and document

• Confirm that emergency power is sustaining the essential loads. Note any deviations and report them through the proper channels. Documentation isn’t about paperwork for its own sake; it’s how you track what happened, what worked, and what needs attention for next time.

• Prepare for what comes next

• Assess the situation for the next hours. Are there planned alarms or scheduled care that could be disrupted? Do you have enough backup power to cover the expected duration? Is there a risk to nonessential services that you should pause temporarily?

Common missteps to avoid

In a crisis moment, it’s tempting to take shortcuts. Here are a few traps to sidestep so you stay focused on patient safety.

• Don’t assume it’s noncritical. Even if the outage seems minor, many systems depend on electricity. A blanket assurance that “it’s not a big deal” can lead to delays or skipped safety checks.

• Don’t wait idly for power to return. Waiting can waste precious minutes. If the emergency power system is designed to auto-switch, trust the system and verify its operation; if manual steps are required, perform them with purpose.

• Don’t evacuate everyone immediately without a plan. Evacuation is energy-intensive and risky, especially during a blackout. Move patients only when necessary for safety, and follow established egress routes and triage guidelines.

• Don’t underestimate the power of communication. Silence or confusion breeds anxiety. A quick, consistent message to staff and patients helps keep the environment orderly.

Prepping for power resilience: practical steps you can take

Preparation isn’t glamorous, but it pays off when pressure mounts. Here are practical ways facilities and teams can strengthen resilience.

• Redundancy and testing

• Ensure critical circuits have redundant feeds when possible. Regularly test emergency generators and transfer switches according to the facility’s schedule. Run drills that mirror real outages so staff are accustomed to the rhythm of a power failure.

• Equipment readiness

• Keep maintenance checks on life-support and critical monitoring devices. Ensure battery backups (UPS) are within their service life and ready to bridge short outages. Stock portable chargers for essential devices and keep flashlights in visible, accessible spots.

• Clear roles and lightweight protocols

• Publish concise, easy-to-follow steps for staff. Use quick checklists that can be read at a glance. During an outage, people act faster when they know their job and how success will be measured.

• Rooms and spaces designed for safety

• In patient rooms, ensure bedside lighting remains functional during outages. For rooms housing patients on devices, ensure access to manual ventilation backup or a plan for rapid repositioning if needed. In the unit as a whole, maintain safe circulation paths with adequate illumination.

• Communications and documentation

• Predefine who informs whom and how. After-action notes help improve future responses, turning a tense event into a learning moment.

A real-world moment to connect the dots

Picture a hospital wing during a summer storm. The lights flicker, the hum of the HVAC quiets, and a nurse checks a screen that suddenly goes dark. In seconds, the emergency generator kicks in, and the corridor lamps glow to full brightness again. A supervisor confirms that life-support devices are on essential power, and a quick coordination call ensues: “Status of ventilators? Battery levels? Patients stable?” The team moves with practiced ease: lines are stabilized, alarms remain audible, and the care plan adjusts to the temporary reality. The outage is inconvenient, but not catastrophic. Why? Because the facility had prepared, trained, and built a culture around patient safety when power falters.

How ATI’s Safety Video resource fits into this picture

Training materials like the Safety Video module are designed to mirror these real-life dynamics. They don’t just list steps; they model decision-making under pressure, show the right sequence of actions, and emphasize keeping patients safe first. The value isn’t simply memorizing a response; it’s internalizing a mindset where readiness becomes instinct. In the moment of a blackout, that mindset translates into calm leadership, clear communication, and a steady hand guiding care.

Final thoughts: safety is a shared responsibility

Power outages test more than equipment. They test teams, protocols, and the culture of safety that surrounds them. The core lesson remains simple and powerful: activate emergency power systems and ensure patient safety. Everything else follows from that choice. By preparing with redundancy, clear roles, and regular drills, healthcare teams can turn a potentially chaotic event into one where care continues seamlessly.

If you’re exploring the Safety Video resource and related training materials, you’re not just studying rules—you’re building the habits that protect lives when minutes count. It’s about being present, being prepared, and staying focused on the patient you’re serving. After all, there’s no great mystery here: in health care, power is more than electricity. It’s a lifeline, and keeping it alive is a shared, everyday commitment.
