Nuclear siren to be tested

Have your say

PORTSMOUTH’S naval base was due to test its nuclear emergency siren this morning.

The sound, a wavering tone, will last for one minute.

A Navy spokesman said: ‘By agreement with the local authorities, the siren is tested three times a year – on the last working days in February, June and October – as part of the nuclear accident response plan for the naval base and in accordance with Portsmouth and Gosport councils’ nuclear safety plan.’
