Eternit in windowsill?

[Lämmelen]

Hello!
I have seen some threads about similar issues and now I'm also coming to ask. I live in an apartment in a building built in 1938 and have window sills like these. Do you think they are asbestos cement? It's peeling a bit on the underside of what seems to have been an extra layer of something. It does look quite unsightly, but could it be dangerous to remove? There's tape on the sharp edges of one vent because it's in my son's room.
Thanks in advance for the answers.

No one who knows?

Looks like Granite. Eternit window sills were usually patterned on the underside and marked with the manufacturer's name. Like: Lommaskivan, or similar.
So. No. Not dangerous at all. Not even if it had been eternit, it wouldn't be dangerous for anyone unless the board fell on your toe.

Thank you for the response! It sounds promising.

Even if it's asbestos cement, there's no danger as long as you don't saw into it.
But the tape that's peeling off is probably a painted metal box for ventilation, right?

Yes, it's for ventilation. But it's also peeling on a layer on the underside of the countertop, so it felt a bit suspicious.

Eternit does not flake.

Eternit does not flake.

I thought it was some strange extra layer with unpleasant additives in it as well, but maybe I'm being too paranoid after all the reading about asbestos. Thanks for your replies!

but I might be overly paranoid after all the reading about asbestos.

Like 99.9% of everyone who googles asbestos.

Eternit doesn't peel.

Tell that to my old garage roof But indoors, no, it doesn't.

Doesn't really look like eternit. Painting the underside with something like clear varnish regardless of what it is might be easiest. Not because eternit is dangerous, but because you don't want flakes falling off whether it's paint, varnish, or eternit and scraping is a hassle...

Really doesn't look like eternit. Painting the underside with something like clear lacquer, no matter what it is, might be the easiest. Not because eternit is dangerous, but because you don't want flakes falling regardless of whether it's paint, lacquer, or eternit, and scraping is a hassle...

Great tip with the lacquer, thanks!
