Where Should You Install an AED? Best Practices for Singapore Buildings

Buying an AED is the easy part. The harder decision is where it lives.

A defibrillator locked in a fire command room, mounted above head height, or signed so poorly that nobody can find it under stress is still counted as "installed." It just will not reach a collapsed person in time.

This guide covers practical placement for Singapore buildings: visibility, retrieval distance, signage, mounting height, and maintenance. It is informational best practice drawn from public resuscitation guidance and local public-access programmes, not a substitute for legal, fire-safety, accessibility, or manufacturer instructions that apply to your premises.

Start with retrieval time, not a nice map pin

The governing metric is how long it takes a runner to get the AED to the patient, not how pretty the location looks on a floor plan.

The American Heart Association's public-access defibrillation guidance uses a three- to five-minute round-trip as the planning target for delivering a shock after collapse. In practice, that means:

Place the device so a trained or untrained bystander can reach it and return quickly.
Count real walking time through corridors, lifts, turnstiles, and doors.
Add more devices when one cabinet cannot cover every occupied zone within that window.

Do not treat a straight-line metre measurement as enough. A cabinet two floors away behind a keycard gate can be slower than a lobby device further along the corridor.

If you manage a condo or HDB block, also remember that most out-of-hospital cardiac arrests in Singapore happen at home. Placement in the residential lift lobby or another 24-hour common area beats a clubhouse that closes at night. See why every condo and HDB block should have an AED.

Choose locations people already pass through

Good AED sites share three traits: people walk past them, people can describe them quickly, and people can reach them whenever the building is occupied.

Strong candidates in Singapore buildings:

Lift lobbies and main circulation corridors
Reception desks and concierge counters that stay staffed during operating hours
Gym floors, pools, and sports halls, where exertion raises risk
Cafeterias, auditoriums, and large meeting floors
Security posts that remain open after office hours, if the device itself stays publicly reachable

Weaker candidates:

Locked fire command rooms or key-only stores
Manager offices that empty at 6 p.m.
Basement plant rooms with no signage trail
Cabinets hidden behind temporary renovation boards or seasonal displays
Devices that only open with a staff key when no staff are present

SCDF's Save-A-Life residential approach is a useful local model: place public-access AEDs where people live and circulate, notably lift lobbies, then register them so responders can find them. High-yield public sites in Singapore research have also included transport facilities, sports venues, hotels, and healthcare settings. Match placement to where people actually collapse or gather, not where the wall happens to be free.

Visibility: if you cannot spot it, you cannot retrieve it

An AED should be obvious from the main approach before anyone has to hunt.

Practical visibility rules:

Mount the cabinet where it can be seen from the primary corridor or lobby approach.
Keep furniture, plants, noticeboards, and temporary displays clear of the face of the cabinet.
Prefer a bright, standardised AED cabinet over a plain cupboard that blends into the wall.
Light the area. A dark recess next to a fire hose reel is a poor emergency landmark.
Brief security, reception, cleaners, and facility staff so they can point to it without guessing.

If the device sits around a corner from the main lobby, treat that as a signage problem, not a "clever discreet install." Discreet cabinets save aesthetics and lose seconds.

Distance and coverage: one AED rarely covers a whole complex

Ask a blunt question: from the farthest occupied point on this floor or in this tower, can a person fetch the AED and return while CPR continues?

If the honest answer is no, you need another device, a better location, or both.

Coverage checks that matter in Singapore buildings:

Separate towers often need their own cabinets, even if they share one MCST or landlord.
Multi-level retail pods may need devices on more than one level if vertical travel is slow.
Offices with turnstile lockdown need a device reachable after hours, or a documented security retrieval procedure that still works in practice.
Condos that put the only AED in a clubhouse should check whether residents can reach it at 2 a.m.

Keep a primary and a backup in mind for large sites. The backup can be another owned device or a neighbouring public-access AED, but only if staff know the exact floor, landmark, and access hours. Use AEDLocator and on-site checks when mapping coverage. See how to check if an AED is nearby and why access depends on opening hours.

Signage: label the device and mark the path

A cabinet without signs forces people to search while someone is dying. Signage is part of the installation, not an optional sticker pack.

Best practice, consistent with international resuscitation programme guidance:

Place a clear AED sign at the device itself, not only a generic "defibrillator" label.
Use the internationally recognised heart-and-lightning AED symbol.
Add directional signs at decision points: corridor junctions, lift lobbies, stair exits, and main entrances.
Make lettering large enough to read from a distance. ILCOR-linked programme guidance recommends lettering about 12 cm high so it can be read from roughly 50 metres, with the AED location identifiable from much farther in open sightlines.
Inspect signs at least yearly, and replace faded, peeled, or blocked ones immediately.
Illuminate outdoor or night-access cabinets so the sign and door remain readable.

In Singapore malls and offices, also put the location into staff induction materials, fire warden packs, and security SOPs. A sign helps strangers. A briefing helps the people who will be asked first.

Mounting height and physical access

Mount the AED so a wide range of adults can open the cabinet and remove the device quickly without a stool or a struggle.

Common accessibility practice used internationally is to keep the cabinet handle reachable at roughly waist to chest height, often discussed as no higher than about 122 cm (48 inches) from the floor to the operable part. Singapore buildings should also check any applicable accessibility or barrier-free design requirements for the premises, plus the cabinet manufacturer's mounting instructions.

Other physical rules that prevent bad installs:

Do not bury the cabinet behind a door swing or behind a freestanding directory stand.
Avoid protruding fixtures that create a corridor hazard. If the wall projection is bulky, consider a recessed cabinet where the structure allows.
Prefer unlocked access. If theft is a concern, use an alarmed cabinet rather than a padlock. A locked AED that nobody can open is not a public-access AED.
Keep the approach clear for a runner carrying the device back at speed.

After mounting, open the cabinet, remove the AED, and put it back. If that feels awkward for a shorter adult or someone in a wheelchair, remount it.

What to put with the AED

The device alone is not a complete rescue kit. Keep supplies with the cabinet or in the carry case:

Unexpired adult electrode pads, ideally with a spare set
Paediatric pads or a child mode if children regularly use the premises
Scissors for cutting clothing
A disposable razor and cloth or towel for preparing the chest if needed
CPR face shields or pocket masks, if your programme includes them
Nitrile gloves

Check the manufacturer's list and any CERT or workplace first-aid requirements that apply to your site. For CERT premises and broader workplace rules, see AED rules in workplaces, gyms and public spaces.

Maintenance routines that keep the AED rescue-ready

AEDs self-test, but self-tests do not replace a human inspection schedule.

Assign a named owner, such as facilities, security supervisor, or MCST contractor, and run a written checklist:

At installation

Insert the battery and activate the unit exactly as the manufacturer instructs.
Confirm the status indicator shows ready.
Log serial numbers, pad expiry dates, battery expiry or install dates, and cabinet location.
Register public-access devices with SCDF so they can appear in myResponder. Current registration guidance is on SCDF's AED hardware page.

Weekly or monthly visual checks

Status indicator is green or otherwise "ready," depending on the model.
Cabinet is unlocked or alarm-ready, undamaged, and unobstructed.
Signage is still visible.
Pads and batteries are within date.
Rescue supplies are present and sealed where relevant.
No moisture, heat damage, or vandalism.

AHA programme guidance commonly points to weekly or monthly visual inspections. Use the manufacturer's interval if it is stricter, and never skip checks because "the light looked fine last quarter."

After every use or false deployment

Replace used pads immediately.
Restore supplies.
Follow the manufacturer's post-event checklist.
Document the incident for internal review and any EMS follow-up your programme requires.

On a fixed calendar

Reorder pads and batteries before expiry, not after.
Recheck software or field updates with the supplier.
Retrain staff and rerun a retrieval drill from a realistic collapse point to the cabinet and back.

An expired-pad AED is a failure wearing a success sticker. So is a device that moved during renovation and never got new signs or a registry update.

A simple placement checklist for Singapore building managers

Before you sign off an install, walk the building and answer:

Can a stranger spot the AED from the main approach without asking anyone?
Can a runner complete a round trip from the farthest likely collapse point within a few minutes?
Is the cabinet reachable whenever people are on site, including nights and weekends?
Are directional signs posted at every place a runner might hesitate?
Is the mounting height practical for a wide range of adults?
Is the cabinet unlocked or alarmed, not key-locked with no keyholder present?
Are pads, battery, and supplies in date and logged?
Do security and reception know the exact landmark?
Has a public-access device been registered with SCDF, with current floor and hours?
Have you drilled the route once for real?

If any answer is no, fix the placement or the supporting programme before you call the site "covered."

After installation, make the location known

Placement only works if people know the plan.

Tell residents, tenants, or staff the floor and landmark.
Add the location to induction packs and emergency floor plans.
Encourage people to check nearby devices on AEDLocator and to install myResponder.
Train people in CPR and AED use, then refresh on a schedule. Course options are covered in community emergency preparedness courses.

In a real emergency, still call 995 first, start CPR, and send someone for the device. Placement decisions exist so that runner already knows where to go. See how to use an AED and what happens when you call 995.

FAQ: AED installation in Singapore buildings

Where is the best place to install an AED in a condo or HDB block?

A 24-hour common area that residents can describe quickly, often a lift lobby or staffed guardhouse approach, is usually stronger than a clubhouse or management office that closes overnight. Confirm access, signage, and a realistic retrieval route from upper floors.

How far apart should AEDs be placed?

Plan around retrieval time, not a fixed floor count. Use a three- to five-minute round-trip target as a planning guide. If one device cannot cover every occupied zone within that window through real corridors and doors, add another.

How high should an AED cabinet be mounted?

Mount it so most adults can open it and remove the device quickly without climbing or excessive reaching. International accessibility practice often keeps the operable height around waist to chest level, commonly discussed as no higher than about 122 cm. Follow cabinet instructions and any accessibility requirements for your building.

Should AED cabinets be locked?

Avoid key-locked cabinets with no immediately available keyholder. If theft is a concern, use an alarmed unlocked cabinet. A locked device that delays retrieval fails the purpose of public-access defibrillation.

How often should an AED be checked?

Follow the manufacturer schedule. As a programme baseline, assign someone to do a documented visual check weekly or monthly: status indicator, pad and battery dates, supplies, cabinet access, and signage. Recheck immediately after any use or after works that could move or block the cabinet.
