Installing an Automated External Defibrillator (AED) in the workplace is one of the most important steps a business can take to improve emergency preparedness. Sudden cardiac arrest can happen without warning, and immediate defibrillation significantly increases survival chances. However, simply having an AED on-site is not enough. Its location plays a critical role in ensuring it can be accessed and used quickly when every second counts.
So where should you place an AED in the workplace to maximise safety, compliance, and response effectiveness?
Why AED Placement Matters
When a person suffers sudden cardiac arrest, survival chances decrease by approximately 7–10% for every minute without defibrillation. This means an AED must be accessible within minutes. Poor placement - such as storing the unit in a locked office or an obscure cupboard - can delay response time and reduce its effectiveness.
The British Heart Foundation and the Resuscitation Council UK both emphasise the importance of rapid access to defibrillation. Strategic AED placement ensures your workplace is truly prepared.
Key Principles for AED Placement in the Workplace
When deciding where to position an AED, businesses should prioritise visibility, accessibility, and speed of response.
1. Central and Easily Accessible Locations
An AED should be placed in a central area where it can be reached within three minutes from anywhere in the workplace. Ideal locations often include reception areas, main corridors, staff break rooms, or near entrances. In larger premises, multiple AEDs may be required to ensure adequate coverage.
The goal is simple: no employee or visitor should have to travel far to retrieve the device during an emergency.
2. High Footfall Areas
Cardiac arrests are more likely to occur in areas with higher occupancy. Placing an AED in a location with frequent staff or visitor presence improves the likelihood of a rapid response. This is particularly important in workplaces such as warehouses, manufacturing facilities, gyms, retail environments, and large office buildings.
3. Near Higher-Risk Areas
In workplaces involving physically demanding tasks or higher health risks, such as construction sites or industrial facilities, AED placement near active work zones may be appropriate. High-risk environments often require more than one unit to ensure adequate coverage across large or segmented areas.
4. Clearly Marked and Visible
An AED should never be hidden. It should be clearly signposted with recognised defibrillator signage and mounted in a visible cabinet. Wall-mounted AED cabinets help ensure the unit is protected yet easy to identify during an emergency.
Signage should also be positioned throughout the building to direct people to the nearest AED quickly.
5. Accessible at All Times
Accessibility is critical. The AED should not be stored in a locked room or behind restricted access areas unless all staff can enter immediately. If the workplace operates outside standard hours or includes shift work, the AED must remain accessible whenever employees are present.
For outdoor or 24-hour access requirements, secure temperature-controlled cabinets may be necessary.
6. Consider Environmental Factors
AEDs must be stored within manufacturer-recommended temperature ranges. Extreme heat, cold, or moisture can affect performance. In industrial or outdoor environments, protective cabinets may be required to maintain safe operating conditions.
Proper storage ensures the device remains ready for use at all times.
Additional Considerations for Larger Workplaces
Larger organisations or multi-floor premises often require more than one AED. As a general guide, the device should be reachable within three minutes, accounting for travel time to retrieve the unit and return to the casualty.
Businesses should also ensure:
-
Staff know the AED’s location
-
First aiders are aware of access procedures
-
The device is registered on local defibrillator networks where appropriate
-
Routine maintenance checks are conducted
Proper placement must be supported by awareness and ongoing management.
Supporting AED Placement with Training and Maintenance
Strategic placement is only one part of effective AED provision. Businesses should ensure staff are confident in using the device. Modern AEDs provide clear voice instructions and are designed for use by non-medical personnel, but basic awareness training can further improve response confidence.
Routine checks should confirm that pads and batteries are within expiry dates and that the device indicates it is ready for use. An inaccessible or poorly maintained AED is no better than not having one at all.
Creating a Safer, More Prepared Workplace
Correct AED placement significantly improves your organisation’s ability to respond to sudden cardiac arrest. By positioning the device centrally, visibly, and within quick reach, businesses can dramatically increase survival chances while demonstrating a strong commitment to workplace safety.
Emergency preparedness is not just about compliance - it is about ensuring your team has the tools they need when every second matters.
Is Your Workplace AED Positioned Correctly?
Reviewing your AED placement could make a life-saving difference. Ensure your device is accessible within minutes, clearly visible, properly maintained, and supported by staff awareness. The right location today could protect a colleague, visitor, or customer tomorrow.
