COLAS’ Innovation Department has tested a reusable mask on the sites of the Niort and Carpiquet branches, which were mobilized to carry out a test. The OCOV® Mask, manufactured and marketed in France by the company OUVRY, was co-developed in partnership with Michelin and the CEA.

A strong collaboration between the Innovation Department and the agencies to test solutions aimed at improving the well-being and safety of employees.

I’ve been wearing surgical masks every day for three months, several hours a day.

I had the opportunity to try the Voc-Cov mask for a week.

Clearly, it swears with the parade of masks made of “trendy” fabric, it’s eye-catching and it doesn’t fit folded in 4 in the pocket.

Though, over time, no more fogging on the glasses, no feeling of humidity that can make wearing a normal mask suffocating.

It fits well on the face without hurting the ears and it is impossible to put it on wrongly.

When you know the real degree of protection of the DIY masks, it is also a real insurance, as well for oneself as for the others.
