As can be heard briefly in the Five Live clip, a set up where alarms can be clearly heard on air is less than ideal for a broadcast environment. Given the speed at which they had to leave, but also the speed at which they were able to clear the alarm and get back on air, it seems there's not a standard for broadcast stepping-up system in place in Salford?

It could just have been that either the alert was within the broadcast zone or that there were multiple alerts escalating it. 

I'm sure a long time ago a photo was shown of the Breakfast/NWT gallery with orange and red lights with a caption along the lines of now we know what these are for.
