This engineering YouTube explains the engineering/science behind it. It is very specific to building design and whole of system fire suppression and response.

Key words, modern, and specific contexts. Grenfell while tragic isn’t a great example of the thousands of fires that occur daily around the globe where this system works.
That’s survivorship bias at play.

And completely rational and scientific in a given building and context.
In modern buildings where these signs are located each apartment is a fire [proof] cell. It’s much safer to remain isolated from smoke, than be running into it.
Sprinklers, automatic fire suppression, and fire brigade can all deal with a fire before the fire rating of the individual apartment fire cells are breached.
This is for modern buildings in specific contexts. Older buildings not engineered with individual fire cell contained units do not have these messages.
This message is specific to the specific building.

A deceptively tricky shot to get sans clouds and wind.

Thankfully you don’t need to hope, it’s literally on the door.
