 The focus of the Olympic security has understandably been terrorism, but the organizers have numerous  contingency¹ plans for other risks. An obvious concern is London's transport network. A power blackout or fire could cause massive disruption to the Games. This control room in south London is where buses, trains, cars and London's chief networks are monitored, with the police and fire brigade also in the same room, all prepared for every eventuality. 

 

Whether there will be a power cut or there will be a signal failure, but ahead of the Games, we've done lots to ensure that we've done the best maintenance, so that the likely of those incidents we reduce as much as possible. If they do happen, we've got spare parts and forward maintenance team in strategic locations around the network to get things resolved really quickly.

 

 

The Great British weather has already tested the athletes and spectators, but it's also tested those planning for the worst. Floods could force the cancellation² of some events. 

 

 

Obviously, there would be disruption, should something like that happen. And I'm sure that you can't, you can't prevent the rains from falling, but you can manage the consequence of it.

 

 

The food supply to athletes and spectators is one area of concern. How can you prevent food poisoning from poor hygiene³? Melanie Patterson shows there is a new rapid DNA⁴ test to isolate⁵ food box, vital in the event of food poisoning outbreak in the Olympic village. 

 

It's a test that locates the DNA from the bug⁶ that might cause illness, say

 

some (narrowness stare?), for example. Ah....most people in the past for tested culture, but this is the most sensitive and much quicker. So, ah... culture test may take four days to give you negative result, but this give you the same result in just one day. 

 

For more period, you get a real sense of how fast London is and how complex contingency plan is on an ordinary day. That low when you add in a quarter of a million extra visitors for the OlympicsYou get a real sense of how difficult it is to gain play every scenario⁷. But that's exactly what's happening. 

 

The Government's Cobb Emergency Committee have been meeting to talk through the risks and contingency plans which everyone hopes will be never be needed.
