I stumbled across the Sellafield facility's alarms from 2012, back when another company ran the site. This is what I'm talking about: https://www.youtube.com/watch?v=dtNgOeqBKQU
Considering that these alarms were from a decade ago, and that currently Sellafield is run by a different entity nowadays, what are the new warning signals, if they are any different at all? Certainly something has to had changed, since the off-site emergency warning is a group of train horns but according to the UK siren map the three sirens on-site are labeled as possible Klaxons or PA systems, could these be where the different sounds come out, or is there a chance of other megaphones around the outdoors portion of the site?
