Every building site needs an AED, but which one is best for you?

Across the nation, more than 25,000 out of hospital sudden cardiac arrests occur every year. Sadly, less than 10% survive, making sudden cardiac arrest one of our biggest killers. However, the survival rate can improve significantly with early defibrillation.

Before we dive into why the building industry should include AEDs in their first aid and emergency plans, let’s understand sudden cardiac arrest a bit more.

What is sudden cardiac arrest?

Sudden cardiac arrest, sometimes called cardiac arrest or SCA, is when the heart suddenly stops. Your heart’s electrical system controls the rate and rhythm of its pumping. A malfunction in that system causes the heart to go out of rhythm or stop, ceasing to pump oxygen-carrying blood around the body. Every cell in your body needs oxygen, so when the heart stops, it starves your brain and organs; you fall unconscious and stop breathing.

Immediate CPR and early defibrillation may reverse a sudden cardiac arrest to save a person’s life and reduce long-term neurological impairment. The message is clear: Every minute counts.

In fact, for every minute without CPR and defibrillation, the chance of survival drops by 10%. An action plan gives a sufferer the best chance of survival when followed promptly, so in the event of SCA remember these three steps:

Call – for emergency assistance and advanced care.

Push – begin CPR.

Shock – use a defibrillator to restore normal heart rhythm.

Anyone can help save a life with these three steps and The Australian Resuscitation Council says, “any attempt at resuscitation is better than none”.

What is a defibrillator (AED or Automated External Defibrillator)?

An automated external defibrillator (AED) is a portable electronic device that diagnoses life threatening abnormal heart rhythms that can cause a cardiac arrest and the only device that can treat sudden cardiac arrest.

An AED treats these abnormal heart rhythms by giving an electric shock that ‘restarts’ the heart returning it to a normal rhythm. This is defibrillation.

An AED will only give a shock if it is necessary. Therefore, you cannot harm someone by using an AED on under any circumstance. 

• Anyone can use a defibrillator – they have verbal and visual instructions to guide you. 

• You cannot hurt someone by using a defibrillator, even in the rain. 

• A defibrillator only shocks a person who is in cardiac arrest.

AEDs as risk management

Sudden cardiac arrest doesn’t discriminate. It can happen to anyone, at any time, often without warning. However, some factors put the building industry at a higher risk. Having an AED on site is an easy to implement control measure for that risk. Building and construction are known to be high risk occupations. From the physically demanding work, handling of hazardous materials and the increased risk of being injured on the job when compared to other occupations. There is a lot to consider when establishing risk management and safe work plans including the accessibility of an AED.


In Australia, approximately two-thirds of sudden cardiac arrests occur in men. Building and construction is third-largest industry in Australia with males making up 87 per cent of workers, meaning the chance of a construction worker suffering a sudden cardiac arrest on the job should not be ignored. Add in the physically demanding nature of the industry, and the risk increases.

Increased risk for the building industry

Two major contributing factors to the increased risk in the building industry for a sudden cardiac arrest are access and electricity.

Building sites are often difficult to access, which can increase the time it takes for emergency services to arrive, impacting the chance of survival for an SCA sufferer, which is why an onsite AED will save precious minutes and possibly a life. Although they are preventable, electrocutions still consistently rank as a leading cause of fatalities in the construction industry. The human body is a good conductor of electricity, so if a current from outside the body passes through the heart of a healthy person, it can in fact cause cardiac arrest.

Should the unthinkable occur and your site has an on-the-job cardiac emergency, ensure workers are protected with an onsite AED to save precious time.

So which AED is the right choice for your site?

If the above sounds a little confronting, that’s good because it means we have your attention! Have an AED onsite as a part your WHS plans, it is an essential piece of first aid equipment and everyone needs to know its location.

There are many devices on the market with various features, so it’s easy to get confused about which device is the right one for you. That’s where we come in. AED Authority’s mission is to increase the sudden cardiac arrest survival rate by getting more AEDs in more workplaces around the country. That includes your building site. We are experts in all things AED and we are ready to help you tailor an AED solution for your needs and budget.

Knowing where your nearest AED is can save critical minutes and possibly a workmate’s life.



How to set up an AED program

Fitting out your office or place of work with a defibrillator is a great decision that means you’re already on your way to help saving a life. Having an AED on site means you are better prepared to assist someone suffering a cardiac arrest and are investing in the protection of those around you. The purchase of an AED will enhance the first aid capabilities and emergency responses of individuals and organisations of all types. The size and layout of your physical environment will determine the placement of these lifesaving devices, and how many you need to ensure your nearest defibrillator is no more than 90 seconds away.

A complete AED program includes a site assessment to determine the risk of SCA among workers, customers, and other visitors to your site; and to identify possible locations for AEDs. The most important consideration is the physical size of the work area, which determines the “drop-to-shock” timeframe to how long it takes to get an AED to the victim of SCA. The goal is to deliver defibrillation within three to five minutes of the onset of SCA.

Mapping out the facility

AEDs are typically located in lobbies, main hallways, large meeting rooms, and near restrooms. It’s best to avoid remote offices or crowded storage rooms. To assess your workplace and determine the best placement options, start from where you think you would place a device and map how far you can get in 90 seconds in all directions. This is the effective reach of your AED.

For small workplaces, one AED will be sufficient, while large, spread-out facilities could require several devices.

Injury potential

Once the various routes and distances within a building have been timed and marked on the floor plan, the next step in the risk assessment is identifying potential hazards. Understanding both the type and likelihood of possible injuries associated with different work areas within the building can help determine AED placement in the facility. Add these to your floor plan.

A completed AED site assessment provides much of the information you need for a comprehensive and customised AED program.

Putting it all together

Taking all the risk and distance factors into consideration, plan the number of AED devices needed and where they will be installed to reach an SCA sufferer within 3 minutes of collapse.  If your site requires multiple AEDs, we recommended you start AED placement nearest to the highest risk areas then work outwards, always aiming for three minutes or less between AEDs.  If the number of AED devices available for installation is limited but you want optimum coverage, we recommended that the AED is located not more than 90 seconds from the highest risk areas and especially those high-risk areas that are also high traffic. All AEDs should be strategically placed, highly visible, in common areas, and well signed.

Completing and returning our AED site assessment form provides us with crucial information. Our expert team use it to assess your organisation’s needs and provide you with the right advice on implementing an effective AED program.
