Metro Bilbao and EU-OSHA joined forces in an information campaign to raise awareness of workplace safety and health risks. The campaign was addressed to both staff of Metro Bilbao and all subway commuters. It lasted from 26 April (as prior announcement of the World OSH Day) until 9 May, which is the Europe Day, particularly important in 2017 for commemorating the 60th anniversary of the Treaty of Rome. Napo and his work mates were displayed in posters in 10 metro stations and several ticket dispensers. At the same time, Napo character was travelling in different metro lines and stations handing out his DVDs.
