The Venice Carnival is one of the oldest, most famous and loved in the world. For centuries, during the Carnival in the city parties and parades have been held, in which refined and mysterious masks participate, which follow different themes, but always inspired by eighteenth-century costumes. As early as 1271 we have news of craft shops for the production of masks and manuals on construction techniques. It is in the eighteenth century that the Venice Carnival reaches its maximum splendor, acquiring international resonance throughout Europe. The streets, fields and streets are transformed into a large stage where everything seems to become possible for the guarantee of total anonymity. Together in Venice, Mestre and the whole lagoon for over two weeks they turn into an exciting show of colors between theater, music, art and circus. The GAe strategy Safety has been designed for the most important Carnival-related events: the party on the water of Cannaregio, the Flight of the Angel, the Flight of the Eagle, the Svolo del Leon and the Flight of the donkey. The latter take place on the square, therefore they are static events, if not for the movement of the helper from the bell tower to the stage, and with the audience attending the show. It is difficult to quantify the number of both the participants in the event and the citizens who transit or stay in the area for other purposes. With engineering simulations, both decompression areas and areas without public presence were provided. Services For the event, the following were prepared: Safety Plan including the technical-illustrative report for the authorities; Emergency Management and Evacuation Plan; Removal signage; Management of safety operations during the event; Counting management via App; Training of audience management staff; Assumption of the role of Safety Manager and Emergency Coordinator.
