In the UK, workplace safety isn’t just a box-ticking exercise. For managers and health & safety leads, the reality is far more urgent. The risk of sudden cardiac arrest at work is real. Every year, thousands of employees across the UK collapse without warning, and survival depends on what happens in the first few minutes.

An Automated External Defibrillator (AED) is crucial in these moments, but owning an AED alone is not enough. It must be positioned so it can be reached and used within one to two minutes. Otherwise, those vital minutes slip by and the chance of survival falls with every passing moment.

For high-risk environments such as warehouses, manufacturing plants, logistics hubs, and busy commercial properties, the risks are even greater. Large floor areas, multiple levels, and heavy foot traffic all slow emergency response unless there is a clear, HSE-compliant AED strategy.

Getting this right could mean saving a colleague’s life. It is one of the most practical improvements any workplace can make in first aid readiness.

Common Pitfalls

• Assuming one AED in reception is enough — not suitable for large or multi-level sites.
• Letting convenience override risk assessment — easy installation does not equal best placement.
• Poor signage or locked cabinets — AEDs must be visible and accessible.
• Over-reliance on a single first aider — anyone should be able to locate and use the AED.

Step-by-Step Fix

1. Assess and map high-risk areas
Walk the site and identify locations with higher physical demand, isolation, or public access. Ask how quickly help could realistically reach each point.

DefibSpace Tip:
Mark hotspots on your floor plan such as loading bays, stairwells, canteens, and remote offices.

2. Calculate time-to-AED
Physically time a brisk walk from the AED location to each risk area. Aim for under two minutes wherever possible.

3. Choose visible, central locations
Install AEDs in wall-mounted cabinets near key walkways. Avoid locked offices or obstructed zones.

4. Ensure 24/7 access
Confirm AEDs are never locked away, blocked by deliveries, or inaccessible outside office hours.

5. Train all staff and run drills
Everyone should know what the AED looks like and where it is. Run realistic drills from actual working locations.

6. Maintain signage and readiness
Inspect cabinets, signage, and access weekly. Replace damaged or obscured signs immediately.

AED Placement Checklist

• All high-risk zones covered within two minutes
• AEDs wall-mounted and highly visible
• Clear NHS-standard green-and-white signage
• Accessible to all staff, all hours
• Regular access and readiness checks in place

What Most People Miss

Emergencies rarely happen where expected. Effective AED strategies are reviewed whenever layouts, staffing, or access patterns change.

Leading organisations treat AED placement as an ongoing process, not a one-off install.

The Bigger Picture

• Faster response and higher survival rates
• Stronger HSE compliance and legal protection
• Improved staff confidence and safety culture
• Better preparedness as sites evolve

Wrap-Up

AED placement is not a tick-box exercise. By mapping risk, timing access, using clear signage, and training all staff, workplaces can save lives and protect their organisation.
