The public are being reassured when they hear a siren at the BASF base at Low Moor next month, it is just the test-sounding of its off-site emergency siren.

The siren will go off at 10am and at 8pm on Thursday, June 6. It produces a sound of increasing and decreasing pitch and will operate for one minute on each occasion.

A BASF spokesman said: “There is no need for members of the public who hear the siren to take any action.

“The emergency services have been informed of the test sounding of the siren.
