A selection of our visit points require the wearing of a Type 1 surgical mask (minimum acceptable performance class, in accordance with EN 14683).
Please make sure you are equipped with such a mask if requested by CERN visits service.
Other type of face cover (fabric mask, scarf etc) will not be accepted with the exception of FFP2/FFP3 masks (without exhalation valve - except if the exhalation valve is covered with an EN 14683 certified material).
