A child playing in their bedroom, a window left ajar to air the room while the meal is prepared next door: the situation seems harmless, and that is exactly why it continues to cause serious accidents every year.
An accident that mostly affects toddlers
Santé publique France (the French public health agency), which regularly renews its campaign to prevent the risk of children falling from windows, points out that several dozen children fall accidentally from a window or balcony every year in France. These falls from a great height mostly involve children under 6, who account for 62% of cases, and more often boys, at 70%.
When it happens
The agency states that these accidents occur mainly around meal preparation time, in spring and summer, when windows stay open longer to air or cool the room. The recurring scenario is a very brief moment of inattention: a parent busy right next door, a window left open, a child climbing.
Why an existing safeguard is not always enough
This is the most useful point of the campaign, and the least intuitive: a significant share of these falls happen even though a window safeguard was already in place. A piece of furniture left under the opening, a chair, a toy that is too high, are enough to make a safeguard ineffective by giving the child something to climb up to the sill. The risk comes not only from the lack of equipment, but also from what is around it.
What Santé publique France recommends
The core recommendation is simple and unambiguous: never leave a child unsupervised near an open window or on a balcony, and do not place furniture or objects in these spots that the youngest children could climb. It is a reminder to stay vigilant, not a technical solution on its own.
What an opening limiter adds
The sliding window lock is fitted on the inner track, without drilling or glue, and stops the two sashes from moving beyond a certain point. The room can still be aired with a reduced opening, to be set as narrow as possible. Please note: this lock is not a child safety device certified to the NF EN 16281 standard, which specifically governs window restrictors for children. It is a hardware complement to vigilance, not a substitute.
What it does not replace
An opening limiter does not watch over a child. It reduces one possibility; it guarantees nothing if a piece of furniture stays pushed under the window or if the lock is removed for a big clean and never put back. The official recommendation and the equipment work together; one without the other leaves part of the risk intact.
The matching product
The Sliding Window Lock is installed and removed in a few seconds, without drilling, to limit the opening of a sliding window or patio door. The rest of the range is in the SentinHome catalogue.
