The Regional Board of Construction Examination has established guidelines in health and safety matter to be adopted in yards during realization of works to elevated economic and/or strategic importance. The Regional Board's aim was to design an organizational model that can ensure every stage of construction design and realization safeguards the health and safety of workers. This can be achieved by implementing suitable preventive measures and adopting a set of coordinated tools for the safety officers in charge of the yard. Hence, the Regional Board designed an "ideal" model of the prevention and safety system. A significant decrease in the frequency and severity of accidents was observed in the yards, where the above-mentioned safety measures were implemented.
