As with cars, it will soon be possible to go through cleaning tunnels before entering a supermarket. French researchers have developed a self-service disinfection system so that the cart, and the one that pushes it, are completely disinfected.

New in cleaning and purification this morning. And it is a French innovation. It is a disinfection tunnel for supermarkets. You enter with your shopping cart and you come out without any microbes.

I don't know if you've been shopping at the supermarket recently. But we see a lot of people avoiding touching the carts with their hands. They use gloves or wipes because you never know when the disinfection took place. This is precisely the objective of this tunnel: to reassure by offering self-service cleaning.

It also looks like the tunnels in which cars are washed. But smaller, since it is two meters long by one meter wide. You enter it on one side. Inside, there is a kind of fogger that will spray a disinfectant product. And when you leave, in principle, the shopping cart and the person pushing it are totally disinfected.

Should we get in with the cart? Is there no health risk?

A priori no, since the product is only sprayed below one meter ten, therefore only at cart height. And obviously, the mask remains mandatory.

So that's for the French tunnel, manufactured in Tourcoing by the company Alineair. But in China, we are developing tunnels, not for carts, but to disinfect people, from head to toe, with their personal belongings. They are more imposing. It looks like decontamination airlocks. Inside, you have to spread your arms and wait a minute, the time to get disinfected. Fortunately, we stay dressed. And there too, there would be no risk to health, even if the mask is compulsory.

It is currently being tested at Hong Kong Airport. And I imagine that we could soon find this kind of device everywhere. To reassure of course, but also to prevent possible contamination.
