Why Are AEDs Important in the Workplace? | Life-Saving Tools

Sudden cardiac arrest can strike any employee, visitor, or customer without warning, and it remains a leading cause of death in the United States. Every minute without CPR or defibrillation reduces survival by up to 10 percent, which makes an on-site defibrillator a genuine lifesaver before paramedics arrive. AEDs — automated external defibrillators — are compact, battery-operated devices that guide untrained rescuers through each step with clear voice prompts. The Occupational Safety and Health Administration calls AEDs “an important lifesaving technology” for workplace cardiac emergencies, and the evidence backs that up: rapid defibrillation within the first few minutes materially changes outcomes.

How Much Do AEDs Improve Cardiac Arrest Survival?

The survival statistics make the case clearly. Without CPR or a defibrillator, fewer than 5 percent of sudden cardiac arrest victims survive to hospital discharge. Bystander CPR alone improves the odds, but the biggest jump comes when an AED delivers a shock. Communities where volunteers were trained in CPR plus AED use had twice as many survivors as communities with CPR-only volunteers, according to a Public-Access Defibrillation study cited by OSHA. , and that immediate CPR paired with AED use can double or even triple overall survival rates. Survival drops roughly 10 percent for every minute that passes without intervention — which is why having an AED within quick reach matters so much. The table below shows how each step in the response chain changes the outcome.

Building an AED Program That Works

Owning an AED is only the starting point. OSHA recommends a structured workplace program built around several core elements. AEDs should be placed in visible, unlocked locations so anyone can grab one within three minutes from any point in the building. The program must be coordinated with local EMS — many states require employers to register their AED and share post-use data. Employees need hands-on training in CPR and AED use as part of regular first-aid instruction, so the device feels familiar under real stress. A designated program owner should handle ongoing maintenance: checking battery status and pad expiration dates, running manufacturer-recommended inspections, and logging readiness checks. Some programs also require a physician’s prescription to purchase the AED and medical oversight of its use.

Common Mistakes That Undermine AED Programs

Even well-planned programs can fall short on execution, and the most frequent failures are entirely preventable. Storing the AED in a locked cabinet or remote location where nobody can reach it within three minutes defeats its purpose. Skipping employee training means the device is present but nobody is confident enough to use it during a real emergency. Neglecting routine checks on battery life and pad expiration dates can leave the unit nonfunctional when it is needed most. Failing to coordinate with local EMS is another common miss — if emergency services do not know about the AED, they cannot advise whether to use it or prepare for a patient who may have already received a shock. And a critical operational error that occurs in the moment: delaying CPR while waiting for the AED. Compressions should start immediately, and the AED voice prompts guide the rescuer through the shock decision as soon as the device arrives, with another person continuing chest compressions between analyses when possible.

FAQs

Do you need a prescription to buy an AED for a workplace?

Most AEDs are classified as prescription medical devices by the FDA. Many suppliers can help employers obtain a prescription from a medical director or physician who oversees the program. Some states also require that physician to review post-incident data as part of ongoing program oversight.

Can an AED hurt someone if used incorrectly?

AEDs are designed for safe use by untrained bystanders. The device analyzes the victim’s heart rhythm and only delivers a shock if it detects a shockable rhythm such as ventricular fibrillation.

How often should workplace AEDs be inspected?

OSHA recommends regular visual inspections plus following the manufacturer’s scheduled maintenance intervals. Battery status and pad expiration dates should be checked at least monthly and documented in a log. Most modern AEDs run automatic self-tests and display a green readiness indicator so a quick glance confirms the unit is operational.
