Safety Measures For International Visitors:
Every country has its own relevant security checks; likewise, British government might prohibit or restrict those items, which are allowed to be carried in your country.

Usually items that are restricted at airports are very much similar to the ones that are constrained at Olympics venue.
Pepper Spray, fireworks, flares, matches, inflammable liquids and solids, oxidizing material, ticket badges, life jackets, lithium batteries, cigarette lighters, sharp edges metal material items (nail cutter, butter knives, nail filer, etc)
Safety Measures at Venue’s Entrance Gate:
Make sure that you have your ticket with you, or else you will not be allowed to pass through the entrance gate.
If you intend to carry a hand bag then it should be small enough to place it under the chair or in your lap.
The fewer things you are carrying, more quickly you will pass the inquiry and checking spot.
If you are carrying a prohibited item then it will get confiscated by the security, you will not get it back.
Being an asthma patient make sure that you have your medicated asthma pump with you. Do not forget to keep your passport and identity card so that God forbid in unwanted accidents you are easily identified or the security can contact your family.
