Don't panic if you see blue lights heading to Bacton gas terminal - it's just an emergency response test exercise being carried out.

It will involve the police, fire brigade and ambulance, and the testing of site sirens and emergency procedures.

Should you hear the site sirens or see emergency service vehicles in and around the terminal throughout the evening of Wednesday, April 26, from around 5pm to 10pm, it is likely to be associated with the test exercise.

The exercise is being carried out in order to ensure compliance with the Control of Major Accident Hazard regulations 2015.
