Where to install a defibrillator for fast access

Every minute without defibrillation reduces the chances of survival by about 10 percent. A defibrillator that is poorly placed, hard to spot, or locked inside a closed office delays the response almost as much as having no defibrillator at all. The performance of the device never makes up for a poorly thought out location, and a simple model placed in the right spot will always serve better than a sophisticated one tucked away in a quiet corridor.

Choosing the location is the operator's responsibility, just like maintaining the device. It should be planned from the moment of purchase or rental, taking into account how the premises are actually used rather than their floor area alone. A map of how visitors, staff and deliveries actually move around often gives better clues than a plain architectural plan.

A defibrillator must remain accessible at all times, including outside opening hours if the site is still in use. It belongs in a busy area, visible without effort, such as an entrance hall, a reception desk or a main corridor, rather than an office, a storeroom or a locked technical room.

Installation height matters too: the case must remain within reach of anyone, without having to climb or bend down excessively. A well lit spot, sheltered from impacts and extreme temperature swings, extends the life of the device and its consumables.

The visual cue matters as much as the position itself. A green case mounted at height, paired with a compliant sign, can be spotted within seconds even by someone unfamiliar with the premises, which matters as much for staff as for a passing visitor.

The goal is to limit the round trip between any point in the building and the defibrillator. The longer that trip, the longer the delay before the first shock, while professional emergency services generally take several minutes to arrive on site.

In a large building or one with several floors, a single device is usually not enough. It is better to spread several defibrillators across strategic points than to spend the whole budget on one high end model that is poorly placed. A simple exercise is to time the walk from the most remote point of the site, closed doors included, to check that the device is genuinely reachable in an emergency.

The layout of the site directly shapes how many devices are needed and where they go. A few practical benchmarks by type of premises:

A defibrillator locked inside a cabinet, kept in a staff only room that the public cannot reach, or placed in an office that closes in the evening loses much of its value. The principle remains free and immediate access, with no code to ask for and no key to hunt for in an emergency.

Locations exposed to strong heat, damp or direct frost without suitable protection should also be ruled out, along with spots where a sign could not be seen from the main circulation routes. A cluttered shelf, a locked fire door or a poorly lit recess are all obstacles that cost precious seconds.

An indoor defibrillator suits sites where access remains possible at all times. As soon as the building closes while members of the public or nearby residents might still need the device, a heated outdoor cabinet becomes worth considering, since it stays reachable from the public way.

This choice is made case by case, weighing the site's real occupancy hours against the surrounding footfall, rather than applying one rule to every building. A town hall (mairie) open to the public during the day but surrounded by housing may justify an outdoor cabinet, while an office with no evening traffic can do without one.

In every case, the chosen location should be reviewed whenever the premises change: a refit, an extension, a new entrance or new opening hours are all good moments to check that the defibrillator is still in the right spot.
