Presidential Decree 547 of 27 April 1955 was for over half a century the pillar of accident prevention in Italy: 406 articles on machine guarding, electrical installations, lifting equipment, hazardous materials and protective devices.

It remains the period reference for reconstructing safety obligations on sites and in workshops between 1955 and 2008.

All work activities with employees, construction sites included, during its 1955–2008 validity.
