These guidelines apply to conferences, congresses, company conventions and similar events. Depending on the specific context, these indications must be supplemented with those relating to catering (with particular reference to buffet catering).
As things stand at present, only those with one of the "COVID-19 green certifications" are allowed access to conferences and congresses. Persons under 12 years of age and persons exempt on the basis of appropriate medical certification issued in accordance with the criteria defined by the Ministry of Health are exempt from the requirement to hold a COVID-19 green certificate.

  • The maximum number of participants in the event must be assessed by the organisers on the basis of the capacity of the spaces identified, in order to reduce crowds, after consultation with the local health authorities. If the event is split up over several physically separate venues/pavilions, the maximum number of participants for each venue/pavilion of the event must be identified. Consequently, systems for measuring access and limiting and staggering access must be used, including systems for booking the day and time of entry, in order to avoid crowds.
  • Reorganise spaces to ensure orderly access to avoid queues and crowds. If possible, organise separate entrance and exit routes.
  • Providing adequate information on prevention measures, which can also be understood by customers of other nationalities, both through the use of appropriate signs and posters and/or audio-video systems, and through the use of any personnel in charge of monitoring and promoting compliance with prevention measures, also referring to the visitor's sense of responsibility.
  • Promote the use of digital technologies in order to automate organisational and participatory processes (e.g. booking system, payment of tickets, filling in forms, printing of recognition systems, entry registration system, performance of evaluation and satisfaction tests, delivery of participation certificates) in order to avoid predictable crowds, and in compliance with the legislation on the protection of personal data maintain an attendance register for a period of 14 days. If not already equipped with physical barriers (e.g. screens), the secretariat and reception area must be adapted if necessary. Only allow access to properly registered users.
  • Hand hygiene products should be made available for users and staff at several points in the areas (e.g. ticket office, halls, classrooms, toilets, etc.), and their frequent use should be promoted.
  • The speakers' table and podium for presentations should be reorganised to allow a safe distance for speakers/moderators to speak without a mask.
  • The devices and equipment available to speakers, moderators and listeners (e.g. microphones, keyboards, mice, laser pointers, etc.) must be disinfected before initial use by ensuring that they are disconnected from the electrical connection. They should then be protected from contamination by a food-grade or clinical film, which should be replaced for each user if possible.
  • All auditors and support staff (e.g. reception staff, technical staff, classroom tutors), given the prolonged sharing of the same environment, must wear a mask to protect the respiratory tract (surgical mask or device that confers superior protection such as FFP2) for the duration of the activities and frequently hygienically clean their hands with hand sanitiser solutions.
  • In the poster/exhibition areas, reorganise the spaces in such a way as to encourage respect for interpersonal distancing, assessing access quotas, and promoting the remote use of material by participants. Information and scientific materials should preferably be made available in self-service displays (accessed by the visitor after sanitising their hands) or using digital systems.
  • Regular cleaning and disinfection of the rooms must be guaranteed, in any case at the end of each activity of a group of users, with particular attention to the most frequently touched surfaces, toilets and common areas (e.g. refreshment areas, keypads of vending machines for drinks and snacks).
  • Keep doors, windows and glass doors open as much as possible in order to facilitate the exchange of air in the rooms.
    interiors. Depending on the crowding and the occupant's residence time, the effectiveness of the systems must be verified in order to ensure the adequacy of the outside air flow rates in accordance with current regulations. In all cases, crowding must be related to the actual outside air flow rates. In the case of air conditioning systems, it is mandatory to totally exclude the recirculation function, except in cases where it is absolutely and unquestionably impossible to adapt the systems, for which alternative measures to contain contagion must be provided. In any case, measures for natural air exchange and/or air exchange through the system should be further strengthened and the cleaning of air filters should be ensured when the system is not in use, in order to maintain adequate filtration/removal levels. If technically possible, the filtering capacity should be increased by replacing existing filters with filters of a higher class, ensuring that flow rates are maintained. In toilets, the air extractor should be maintained in continuous operation.


A basic green pass means COVID19 Green Certification confirming successful vaccination against COVID-2 sars, recovery from Covid-19 infection or a rapid or molecular antigen test.
An Enhanced Green Pass, on the other hand, is the COVID-19 Green Certification confirming successful vaccination against SARS-Cov-2 or recovery from Covid-19 infection.
The enhanced green pass therefore does not include the performance of a rapid antigen or molecular test.
Only in the orange zone the Super Green Pass is required to enter an event. For white and yellow zone is compulsory the basic green pass.
