Buying an AED for your workplace is a smart first step. But one question often comes up right away:
How many AEDs does your workplace actually need?
There is no single number that works for every business. A small office may only need one AED, while a large warehouse, multi-floor office, school, manufacturing facility, hotel, or campus may need several.
The right number depends more than anything on how quickly someone can get an AED to the person who needs it.
That is why AED planning should focus less on how many devices you own and more on whether those devices can be reached quickly during a cardiac emergency.
Why AED Access Matters
Sudden cardiac arrest can happen without warning.
When it does, the person may become unresponsive and stop breathing normally. CPR should begin right away, and an AED should be brought to the person as quickly as possible.
OSHA notes that public access defibrillation programs can reduce response time by several minutes when AEDs are placed where cardiac arrests may occur.
That is why simply saying, “We have an AED,” is not enough.
The better question is:
Can someone reach that AED, bring it back, and begin using it quickly?
If the answer is no, your workplace may need additional devices.
Start With the Size of Your Facility
Facility size is one of the first things to consider.
A small office with 20 employees may have very different needs than a large office building with several floors or a warehouse that covers hundreds of thousands of square feet.
For a smaller workplace, one centrally located AED may be enough.
For a larger facility, you may need more than one.
Think about:
- Total square footage
- Number of floors
- Number of buildings
- Distance between departments
- Outdoor areas
- Parking structures
- Warehouses or production areas
- Fitness centers or employee gyms
- Public-facing spaces
The farther people have to travel to retrieve an AED, the more important placement becomes.
Multi-Floor Buildings Often Need More Than One AED
If your workplace has several floors, one AED in the lobby may not be enough.
Imagine a cardiac emergency happens on the sixth floor.
If someone has to take an elevator down to the first floor, find the AED, then return to the sixth floor, too much time may pass.
That is why many multi-floor buildings benefit from placing AEDs on multiple levels.
The exact number depends on the building layout, but the goal should always be the same:
Reduce the time between collapse and AED use.
Large Workplaces Need Strategic AED Placement
Large workplaces often need a more detailed plan.
For example, a warehouse may have:
- Administrative offices
- Shipping and receiving
- Production areas
- Loading docks
- Break rooms
- Outdoor yards
- Parking areas
Placing one AED near the front office may not provide enough coverage for employees working at the opposite end of the facility.
The same applies to manufacturing plants, distribution centers, colleges, hotels, government buildings, and large corporate campuses.
Place AEDs where they can be reached quickly, not just where installation is convenient.
High-Traffic Areas Deserve Extra Attention
Another important factor is where people spend the most time.
High-traffic areas may include:
- Main entrances
- Cafeterias
- Conference centers
- Fitness rooms
- Large meeting spaces
- Event areas
- Athletic facilities
- Employee break rooms
These are often good places to consider AED placement because they may serve a large number of people throughout the day.
But visibility matters too.
An AED hidden in a locked office or storage closet is not truly accessible.
Rescue One provides AED cabinets and signage designed to help make devices easier to identify and access.
Think About Your Workplace Population
The number of people in the facility matters too.
A workplace with 25 employees will have different needs than one with 500 employees, plus visitors, vendors, and customers.
You should also think about who uses the property.
Does your workplace regularly have:
- Large meetings
- Conferences
- Public events
- Customers
- Contractors
- Visitors
- Fitness activities
- Older adults
The more people who regularly use the building, the more important it becomes to have a strong AED coverage plan.
Do Not Forget Outdoor Areas
Outdoor spaces are often overlooked.
If your organization has:
- Athletic fields
- Construction yards
- Pool areas
- Parking lots
- Outdoor event spaces
- Golf courses
- Large campuses
You should include those areas in your planning.
An AED inside the main building may be too far away to provide effective coverage for a distant outdoor area.
Seasonal or temporary AED coverage may also make sense for certain locations. Rescue One offers short-term AED rentals for camps, events, pool season, and other temporary needs.
Your AEDs Need to Be Easy to Find
Even if you have the right number of AEDs, they still need to be visible.
Employees should not have to ask:
“Where is the AED?”
Clear signage, accessible cabinets, and regular staff communication can make a big difference.
Organizations should consider:
- Wall-mounted AED signs
- Clearly marked cabinets
- Floor maps
- Employee orientation
- Emergency response training
- AED locations listed in internal safety materials
The best placement plan is one employees already understand before an emergency happens.
More AEDs Also Means More Maintenance
Adding AEDs improves coverage, but it also increases program responsibility.
Each AED needs to be monitored.
That means keeping track of:
- Pad expiration dates
- Battery status
- Device readiness
- Monthly checks
- Serial numbers
- Locations
- Replacement supplies
- Documentation
This is where AED program management becomes especially valuable.
Rescue One’s AED Program Management services include device tracking, automatic notifications for monthly checks and expired supplies, recordkeeping, compliance support, emergency response templates, and other program tools.
For a company with several AEDs, having one system to manage all of them can help reduce the chance that something gets missed.
CPR Training Still Matters
Having the right number of AEDs is only part of emergency readiness.
People also need to know what to do.
When someone collapses, the response should include:
- Calling 911
- Starting CPR
- Retrieving the AED
- Following the AED prompts
- Continuing care until EMS arrives
Rescue One provides CPR and AED training along with onsite group training for organizations of all sizes. Rescue One also offers AED sales, program management, first aid training, and other life-safety solutions.
The strongest AED program combines equipment, training, placement, and maintenance.
So, How Many AEDs Do You Really Need?
There is no universal answer.
The right number depends on:
- Facility size
- Number of floors
- Building layout
- Distance between departments
- Employee population
- Visitor traffic
- Indoor and outdoor areas
- How quickly an AED can be reached
A good rule of thumb is to think in terms of response time instead of device count.
If someone cannot reach an AED quickly from a particular part of your facility, that area may need additional coverage.
The goal should always be to make AED access as fast and practical as possible.
Questions to Ask During an AED Site Review
Walk through your facility and ask:
- Where are our AEDs located now?
- Can employees find them quickly?
- Are any important areas too far away?
- Are some devices behind locked doors?
- Are all floors adequately covered?
- Are outdoor areas included?
- Do we have enough devices for our facility size?
- Are employees trained in CPR and AED use?
- Who manages inspections and replacement supplies?
These questions can help reveal gaps you may not notice on paper.
A Complete AED Program Is Better Than Simply Buying Devices
Rescue One’s approach is built around more than just AED sales.
The company offers AED sales and service, AED program management, CPR and AED training, first aid training, and onsite safety training for organizations of all sizes.
That matters because a strong AED program includes:
- The right number of devices
- Strategic placement
- Clear signage
- Trained responders
- Routine inspections
- Replacement supplies
- Program management
- Emergency response planning
When those pieces work together, your workplace is much better prepared.
The Bottom Line
So, how many AEDs does your workplace really need?
The answer is not simply one, two, or three.
The real question is whether someone experiencing sudden cardiac arrest can receive an AED quickly from anywhere in your facility.
If one device cannot provide that kind of coverage, you may need more.
A thoughtful AED placement plan can help reduce response time, improve accessibility, and create a stronger emergency response program.
Rescue One can help organizations evaluate their AED needs, purchase equipment, manage devices, train employees, and build a more complete cardiac emergency response plan.
