How Workplace AEDs Help Teams Save Lives

When a colleague, visitor or service user collapses without warning, the first few minutes matter more than any policy document. Workplace AEDs give ordinary people a clear, practical way to act while an ambulance is on its way. Combined with immediate CPR and a fast 999 call, an automated external defibrillator can give someone in sudden cardiac arrest their best chance of survival.

For employers, schools, care settings and community organisations, an AED is not simply a piece of safety equipment to mount on a wall. It is part of a planned emergency response. The device must be accessible, maintained and supported by people who know what to do under pressure.

What workplace AEDs do in a cardiac emergency

An AED analyses the heart’s rhythm and, where appropriate, advises and delivers a controlled electric shock. This can help restore a heart rhythm that is compatible with life. It will only advise a shock when one is needed, so rescuers do not have to make that clinical judgement themselves.

The device gives clear voice and visual prompts. A rescuer switches it on, exposes and dries the casualty’s chest if necessary, applies the adhesive pads as shown, and follows the instructions. While the AED is analysing, everyone must stand clear. If a shock is advised, the device will guide the rescuer through it before CPR resumes immediately.

An AED is not a replacement for CPR or emergency services. The strongest response is a sequence: recognise that the person is unresponsive and not breathing normally, call 999, start CPR, send someone for the AED, and use it as soon as it arrives. If there are several people present, these jobs should happen at the same time rather than one after another.

Sudden cardiac arrest is not the same as a heart attack

The terms are often used interchangeably, but they describe different emergencies. A heart attack is usually caused by a blockage affecting blood supply to the heart. The person may be awake and reporting chest pain, breathlessness, nausea or discomfort.

Sudden cardiac arrest means the heart has stopped pumping blood effectively. The person becomes unresponsive and is not breathing normally. They may gasp or make occasional irregular breaths, which can be mistaken for normal breathing. This is a medical emergency requiring CPR and urgent defibrillation where advised.

Do UK workplaces have to provide an AED?

There is no general UK legal requirement for every workplace to have an AED. Employers do, however, have a duty to provide adequate and appropriate first-aid equipment, facilities and personnel. What is adequate depends on a suitable first-aid needs assessment.

That assessment should look beyond headcount. Consider the nature of the work, shift patterns, the size and layout of the premises, how quickly an ambulance could reach the site, and whether staff work alone or in isolated areas. Think also about employees, contractors, visitors, pupils, residents and members of the public who may be on site.

An AED may be a particularly sensible control where there are large numbers of people, public-facing areas, strenuous work, remote locations, sports facilities, older service users or a higher likelihood of cardiac risk. A multi-storey building, spread-out warehouse or industrial estate can also make the distance to an available public device significant.

The question is not simply, “Are we required to buy one?” It is, “If someone collapses here, can our people get a defibrillator to them quickly and use it confidently?” A documented, reviewed risk assessment provides the right basis for that decision.

Choosing an AED for your workplace

Most modern AEDs are designed for use by lay rescuers, but the right choice still depends on the environment. A busy office has different needs from a nursery, a care home, a factory or a community venue.

Start with a device that is straightforward to operate and provides clear spoken prompts. In a noisy workplace, a model with strong visual instructions can be useful. Where staff may need to use the device on children, check whether it includes paediatric pads or a child mode. Adult pads are normally used for adults and children over a certain age or size, while paediatric settings reduce the energy delivered for younger children.

Consider whether the AED will be kept indoors or in an external public-access cabinet. An external cabinet may require weather protection, temperature management and a power supply, depending on the model. A device locked away in a manager’s office, cupboard or reception area outside opening hours is less useful than one people can reach immediately.

Cost matters, but purchase price should not be the only factor. Pads and batteries have expiry dates, and replacement costs need to be planned for. Choose a recognised device from a dependable supplier and ensure that replacement consumables will be readily available. Your organisation should also know who is responsible for checking it.

Placement can save vital minutes

An AED should be easy to find, easy to reach and clearly signed. Put it where people naturally gather or pass through, such as reception, a main entrance, staff hub, sports area or communal corridor. In larger buildings, one device may not be enough. The practical issue is whether somebody can collect it and return to the casualty without losing valuable time.

Avoid placing it behind security barriers, in a room that is frequently locked, or in an area where only a small number of people know it exists. If your site has security staff, reception teams, caretakers or shift supervisors, make the AED location part of their handover arrangements.

Clear signage should point people towards the device from key areas. Staff inductions, fire warden briefings and emergency procedures should all mention its location. In a school or care setting, this should include agency staff and regular visitors who may need to respond before a trained colleague arrives.

Maintenance is a safety responsibility, not an afterthought

An AED cannot help if its battery has expired, its pads are missing or its status indicator shows a fault. Allocate ownership to a named person or role, with cover for holidays and absences. A short, recorded check at planned intervals is far better than assuming the device remains ready.

Your checking routine should cover the following:

• the device status indicator and any self-test warning

• pad and battery expiry dates

• the presence of adult and paediatric pads where required

• the response kit, including gloves, scissors, a razor, a face shield and a towel

• cabinet access, signage and any damage or obstruction

After an AED has been used, replace any used pads and check the manufacturer’s instructions for downloading event data or returning the device to readiness. Review the incident as well. Staff may need emotional support after responding to a life-threatening emergency, and the organisation may identify practical improvements to its emergency plan.

Training turns equipment into effective action

Anyone can use an AED in an emergency and should not delay because they lack a specific AED certificate. The device is designed to guide the rescuer. However, practical Basic Life Support and first aid training makes a real difference to how quickly and calmly people respond.

Training gives staff the chance to practise recognising abnormal breathing, making a confident 999 call, delivering chest compressions, using training pads and coordinating as a team. It also addresses the small but important details that can cause hesitation: removing medication patches from the chest, drying wet skin, managing excessive chest hair, keeping clear during analysis and continuing CPR without unnecessary pauses.

For organisations with several shifts or multiple sites, train enough people to create genuine cover rather than relying on one enthusiastic first aider. The right number depends on your first-aid needs assessment and who is present at different times. Refresher practice matters because confidence fades when skills are not used.

Training 2 U delivers practical, instructor-led Basic Life Support and workplace first aid training across Merseyside, Lancashire, Cheshire and Greater Manchester. With more than three decades of frontline clinical experience behind the training, teams can practise the actions that matter when every second counts.

Build AED use into your emergency plan

A written procedure does not need to be complicated, but people must know their role. Agree who calls 999, who starts CPR, who retrieves the AED and who meets the ambulance at the entrance. In a large site, tell ambulance control the precise access point, floor and route to the casualty.

If your workplace has lone workers, consider how they summon help and where the nearest accessible AED is located. If the building hosts the public, decide whether the device is available to visitors and how staff will support them. Organisations sharing premises should coordinate their arrangements rather than assuming another tenant will deal with an emergency.

Protect your people by treating an AED as part of a live safety system: visible equipment, capable responders, regular checks and a rehearsed plan. The moment somebody collapses is not the time to discover where the key is kept, whether the pads are in date or who is willing to take charge.
