And equally precisely we should talk about disinfection against Sars-CoV-2, which is the virus, of the coronavirus family, responsible for the infamous Covid-19 disease.However, the sanitation of the workplace is an obligation of the employer that has existed for years, according to the provisions of law 81/08 (and previously 626).
