Each National Scout Organization has its own rules.
But for the 22nd World Scout Jamboree there is an online-course on Youth protection for all adults taking part in the Jamboree as Scout Leaders, as members of the International Service Team or Contingent Management Team.
It can be found under: http://safefromharm.se/
If there is an international event in Europe with Scout groups from different National Scout Organization you talk about the national rules before and design the rules for the event so that everyone feels comfortable.
As a guideline you can use: WOSM: Guideline on Risk Management Policy
and Europe Region WAGGGS/European Scout Region(WOSM):Child Protection Tool-Kit.
This applies to a local event such as a meeting for a weekend or a small international summer camp i.e. with Scout groups from Tyrol (Austria), South Tyrol (Italy), Bavaria (Germany) and BSA Units (TAC).
On bigger Scouting events such as National Jamborees or Regional Jamboree the organisation team follows the guidelines of WOSM and WAGGGS and the local laws of the country.
BSA Troops from the U.S. took part in National and Regional Jamborees in Austria in the last ten years and had no problem and did feel fine.
In example the Swiss Scouts (PBS) follow the guidelines of the goverment agency Youth and Sport (Eidgenssisches Bundesamt Jugend und Sport) and the Guidelines of their association. The local Leaders are supported by special trained Coaches/Mentors and their regional Scout organization (Corps,Kantonalverband(similar to BSA Councils)).
In all European Scout Organizations there is well designed Leaders Training.
