The Grangemouth Petroleum and Chemical Complex Major Incident Control Committee (MICC) public warning system is tested twice a year: on the first Wednesday in June at 7.00pm and the first Wednesday in December at 2.30pm.
What does the siren test sound like?
The test consists of activating all five sirens simultaneously as an alert warning, a two tone undulating sound for five minutes followed by a one minute interval and, finally, the all clear sound, which is a single continuous tone for five minutes.
Why are siren tests carried out?
The aims of the siren tests are, to check the operating systems, to monitor the sound footprint in relation to varying weather conditions, to maintain and improve the awareness level of the population and the necessary actions required, summarised as GO IN, STAY IN, TUNE IN.
We encourage everyone in Grangemouth to familiarise themselves with the differing siren tones and also to consider their own procedures / arrangements for reacting to such an alert.
