To safeguard the safety of passengers and/or aircraft, international rules apply on what passengers can or cannot carry on board an aircraft.

This means that all pointed or blunt items that may be used as an attack weapon are strictly forbidden in the aircraft cabin. The European Union has also adopted additional security rules that restrict the amount of liquids and gels that can be taken through security checkpoints.

These rules have been in place since November 2006 and apply to all passengers departing from airports in the EU, Norway, Iceland, and Switzerland, regardless of their destination.
