RESIDENTS in the East End were jolted by the sound of a loud siren going off this morning. 

The sharp and distinct alarm was blasted at 10am for around one hour. 

Gas network company SGN ran the siren as part of a routine test.

The siren is used to warn people living or working near the site of any potential incidents at the complex.

The company conduct tests every six months at all LNG sites, always notifying residents and businesses by letter beforehand.

This test is a requirement as part of the Control of Major Accident Hazards (COMAH) Regulations 2015.

SGN spokesman Waseem Hanif said: “We carry out these tests every six months because the safety of the Provan community is really important to us. While the test scheduled at 10am on Thursday, April 22 is routine and nothing to be concerned about, it’s important nearby residents and businesses are familiar with the sound of the siren and know what they need to do in case a real incident ever takes place.
