An emergency exercise will take place at the Norfolk and Norwich University Hospital this week. Staff will be taking part in the training exercise from 9am until 2pm on Wednesday with a small number of volunteers acting as casualties.

A spokesman for the hospital said the N&N will remain open as usual and patients should experience little or no disruption during the exercise.

'The training exercise aims to test how hospital staff would respond to a major incident, such as a road crash involving multiple casualties to a large chemical spill or explosion. Exercises such as this help the NHS to evaluate the effectiveness of a response to a major incident and develop their emergency plans,' said the spokesman.
