This is a very important process that everyone has to do

and is for the safety of all air travellers.

There will be another queue to join and waiting times can vary a lot.

It may be noisy and crowded with the possibility of warm, even high, temperatures.

Again, it will be important to check that you have none of the prohibited items for air travel.

When you arrive at the security check area,

you will be asked to do several things that may feel uncomfortable or unusual,

but these things are important for all air travellers to ensure safety.

You will be asked to place any hand luggage or bags you will be taking on to the plane into a special tray.

You will also have to place any loose items, like phones, electronic devices,

keys, coins and any other metallic items into this tray.

You may even be asked to remove your shoes, belts,

brooches or tie-pins, if they are metallic or have metal on.

The tray will then pass through a machine that can see inside your bag

or other items, with x-rays.

You will then be asked to individually pass through a big arch,

that is a metal detector machine,

to check you haven't forgotten to place any items in the tray,

but sometimes an alarm sound will go off as you pass through the arch.

This will indicate to the security people

that there is still something metallic on you or in your pocket.

If this happens, there will be an additional check

made by an individual security person.

You may be asked to allow a security person

to rub a small piece of cloth on your shoes

This swab will then be placed into a detector machine

and will check for any prohibited chemicals or substances.

Once scanner checks are completed, you'll be asked to collect your items

from your tray at the end of the conveyor system.

The conveyor system is often quite loud and clunky.
