I read that some people down in Europe got some trouble with the ski things being everywhere in a flat. So I looked about EU-standard for this and this is the list i got:
EN 15507:2008
Packaging – Transport packaging for dangerous goods – Comparative material testing of polyethylene grades
CWA 15902-2:2008
Lifting and Load-bearing Equipment for Stages and other Production Areas within the Entertainment Industry – Part 2: Specifications for design, manufacture and for use of aluminium and steel trusses and towers
