If you set off an alarm on the metal detector gate, a security officer will determine why this has happened. You will be asked to remove any items that may have caused the alarm and then walk through the metal detector again.
The staff may also conduct a pat down search. Sometimes, the security officer will need to use their hands to check on the inside of your trouser or skirt waistband.
The Finnish Transport and Communications Agency (Traficom) requires us to perform more detailed inspections, based on random sampling, on a certain number of passengers passing through security control. At Finavia airports, the inspections based on random sampling are carried out using explosives trace detectors (ETDs).
