Participation in the event was conditional upon registration via internet, Company intranet or telephone.
Applications for tickets could be made by employees of U. S. Steel Košice and its subsidiary companies for themselves and their family members, i.e. wife, husband or partner plus children or grandchildren.
In an attempt to enable every employee who is interested to take part in this event, for the first five days from May 11 priority of registration was given to those steelmakers who had not been to any of the previous open days. After this initial period, starting from May 16 registration was open to all employees. The popularity of Family Safety Day is confirmed by the fact that registration capacity was reached even before midday on May 16.
