A cardiac emergency does not wait for the right employee to be on shift, the AED cabinet key to be found, or a manager to remember the response plan. The top workplace AED mistakes usually happen long before an emergency – during purchasing, planning, training, and routine equipment checks. The good news is that most are preventable when an organization treats its AED program as an active part of workplace safety rather than a device mounted on a wall.
For employers, schools, fitness facilities, offices, and community organizations, an AED can be a critical part of a fast response to sudden cardiac arrest. But the device only helps when people can find it, use it, and trust that it is ready.
1. Treating the AED as a one-time purchase
Installing an AED is a meaningful step, but it is not the end of the job. Batteries expire, electrode pads have expiration dates, cabinets and signage can be moved during renovations, and personnel change. A device that worked perfectly when installed may not be ready years later if nobody owns the maintenance process.
Assign a specific person or role to oversee the program, with a backup person in case of absence. That responsibility should include checking the device status indicator, confirming that pads and batteries are current, reviewing the response supplies, and documenting each inspection. The right schedule depends on the manufacturer instructions and your organization’s policies, but consistency matters more than good intentions.
An AED should be treated much like a fire extinguisher or first aid kit: visible, inspected, accessible, and ready without hesitation.
2. Putting the device where it is convenient, not where it is needed
An AED stored in a locked office, behind a reception desk after business hours, or deep inside a staff-only area may technically be on site but still be out of reach when seconds matter. Sudden cardiac arrest can happen in a lobby, classroom, break room, warehouse floor, athletic space, or parking area. The best location is based on where people gather and how quickly someone can retrieve the device.
Walk through the building from the perspective of a bystander. Could a new employee, visitor, substitute teacher, or contractor identify the AED quickly? Is the cabinet clearly marked? Can it be reached during all operating hours? Are there barriers such as locked doors, stairwells, or security procedures?
Large facilities may need more than one device. There is no single placement answer for every workplace. Building size, layout, population, activities, and response time all affect the decision. A practical site assessment is far more useful than choosing a location solely because there is an empty wall there.
3. Assuming employees will know what to do without practice
AEDs are designed to provide clear voice and visual prompts, which makes them approachable for lay responders. Still, hearing prompts from a device for the first time during a real emergency is very different from using one during a hands-on class. Stress can make simple decisions feel difficult.
Employees should know how to recognize a possible cardiac arrest, call 911, begin CPR, retrieve the AED, apply pads, and follow the prompts. They should also understand that the AED analyzes the person’s heart rhythm and will advise a shock only when appropriate. The device guides the process, but confident people make the response faster.
This is why workplace CPR and AED instruction should include realistic practice. A recognized, instructor-led program gives participants the chance to handle training equipment, work through team communication, and ask questions without pressure. For Richmond-area groups, Richmond Training Concepts provides practical AHA and HSI training that helps staff move from uncertainty to action.
4. Training only a small group of people
Some organizations designate a few safety leaders and assume everyone else can wait for them. That approach can create a serious delay if the designated responder is off site, on another floor, helping a customer, or simply not nearby when the emergency occurs.
A smaller workplace may reasonably identify a core response team, but more employees should still receive CPR and AED training when possible. At minimum, staff should know the AED location, the emergency communication process, and that they should begin helping rather than standing back to search for a single certified person.
Coverage also matters. Consider different shifts, remote areas, weekends, seasonal staff, and employee turnover. A response plan that works at 10 a.m. on a Tuesday may fail on an evening shift or during a crowded event. Training plans should reflect the way the organization actually operates.
5. Forgetting the first minutes before the AED arrives
An AED is a major part of the response, but it is not the only part. When an adult or teen suddenly collapses, is unresponsive, and is not breathing normally or is only gasping, the immediate priorities include calling 911, sending someone for the AED, and starting high-quality CPR.
A common mistake is having one person leave the victim to search for equipment while nobody starts compressions. Another is allowing several people to give conflicting directions. Simple role assignments can reduce confusion: one person calls 911 and meets emergency responders, one starts CPR, one retrieves the AED, and others help manage the area or rotate compressors when trained.
Those roles do not need to be rigid. With only one or two people present, responders will do what they can until help arrives. What matters is avoiding unnecessary pauses and following the emergency dispatcher’s instructions along with the AED prompts.
6. Skipping a plan for children and special settings
Not every workplace serves the same population. Schools, child care programs, youth sports organizations, medical offices, and community centers need to think through pediatric response as part of their AED planning. Depending on the AED model and the age or size of the child, pediatric pads or a pediatric setting may be appropriate.
The key mistake is assuming adult equipment and procedures automatically cover every situation. Review the specific AED model, make sure appropriate supplies are available where needed, and train staff on their role. K-12 staff may also need plans for field trips, athletic events, after-school activities, and facilities shared with the public.
This is also a reason to avoid generic, online-only training that never lets participants practice with an AED trainer. A credible course can explain how the guidelines apply to the people your organization serves while giving participants the hands-on repetition that builds confidence.
7. Letting access procedures slow the response
Security is necessary in many workplaces, but an emergency plan should not require multiple approvals. If an AED cabinet is alarmed, employees need to know that opening it during a suspected cardiac emergency is the right action. If emergency equipment is in a locked room, there must be a reliable way to access it immediately.
Review procedures with reception staff, building security, managers, and after-hours teams. Ask direct questions: Who calls 911? Who can direct EMS to the right entrance? Does the elevator require a badge? Does the front desk know where the AED is located? Can a visitor spot the signage?
A short drill often exposes issues that a written policy misses. The purpose is not to create a dramatic exercise. It is to identify friction before a real person’s life depends on a fast, coordinated response.
8. Allowing certification and readiness to expire together
CPR and AED skills fade when they are not used. Certifications also have renewal periods, and staff turnover can quietly reduce the number of trained responders. A spreadsheet, calendar reminder, or training roster can keep the organization ahead of renewal dates instead of scrambling when a credential is about to lapse.
Do not view renewal as a paperwork task. It is an opportunity to refresh compression skills, review AED placement, correct changes in your emergency procedures, and bring new employees into the safety culture. Employers with multiple departments or shifts may benefit from on-site group training because it can include the actual environment where staff would respond.
Building a Workplace AED Program People Can Use
The strongest AED programs are simple enough to work under pressure. Employees know where the device is, the equipment is checked, more than one person can respond, and the organization practices a clear sequence: call 911, start CPR, get the AED, and follow its prompts.
No workplace can plan for every emergency, and no training can remove the stress of a real event. It can, however, replace avoidable uncertainty with useful action. A well-maintained AED and a prepared team send a clear message to employees, guests, and families: if the unthinkable happens here, people will be ready to help.
