INEOS/Inovyn have one of their main manufacturing sites located in Newton Aycliffe, in County Durham. The site employs 2-3 sirens to act as its Major Incident alarm, and these are tested weekly, at 10:45. Tests usually consist of four or five blasts in the "wail/attack" tone, with roughly 20 seconds of "alert/all clear" following after a short break. It was nice to once again hear the “attack” warning from a 10-12, having only previously heard it from the Calderdale GP12 - my three visits to Portsmouth have all been fruitless, and no other site I’ve visited to date has used the signal.
It isn't known specifically what sirens are used here, nor where exactly they are within the site - though from what I could hear, it sounds like one is in the north-west corner of the site, with another being on the east side.
