Really interesting to see. Does anyone familiar with the system have any more insight? How is the foam discharged? Is it likely to have been dangerous for staff on the ground?

Depends if that foam has fluorinated surfactants in it. If it has then it will need to be scooped up and incinerated,the burnt residue is tiny. If it hasn't got fluorine or other nasties in it then the slow discharge into the public sewerage system may be allowed, but it needs to be done to prevent polluting open waterways and closed courses. There will be a well managed drill for this at Heathrow I'm sure, due to the use of foam in training exercises.
. Good insights though CWS..

We had an accidental discharge at work and the root cause was a faulty microswitch in the emergency release button. Nearby work caused vibration which caused a short, that definitely counts as a malfunction, as would any sensor that incorrectly detected a fire/smoke.

This isn't an isolated incident as Delta had a similar incident at the end of March!

Hi Tottie, do you have any more info about the system? So is the entire hangar rigged with a system that will douse the space in foam? Do all the maintenance hangars have this. Is there not a chance to cancel the alarm once it is triggered, before the suppressant is released?

At that point a message would sound on the loudspeakers: ‘would inspector Sands come to the control room immediately’.

He has been around for a few years and have heard him paged a few times now whilst traveling in London. Have told a few family members and work colleagues about this and twice now on hearing it I have edged my way towards an exit in order to be the first out. The first time I heard it the place was evacuated so was one of the first out, the second time it was stood down.
