I was also told that Virgin Atlantic crew trained for the B744 are trained on how to operate this device in an emergency.
Does the B744 does actually have such a device? Is it optional/ airline specific?
Will the A380 have such a device on its stairways?
I'm also curious if any A346 equipped with the lower level galley and lavatory (i.e. Lufthansa) have such protective devices?
Browsing several pictures of the B744, A380 and A346 I can't see any such fire/smoke doors, and surmise that it would be difficult to fit such a device on the A380 or A346 due to the curvatures of the interior fittings and paneling. I'm also guessing that such a device would be difficult to install on older 747 eqipped with spiral staircases.

I've done a search of the Tech/Ops and Civil Aviation forums, but couldn't find any postings on this topic.
