Much of the subsequent attention has been on protecting tunnel structure by so-called ‘passive’ means, but humanitarian concerns must be focused on the speed of getting travellers away from the hazardous areas as soon as possible, for the dangers to life work much more quickly than dangers to structure. Maurice Jones reviews some best practice and developments to improve the chances of survival
