Hi

Looking for some advice about something that's started worrying me recently if anyone can help please? I lifted laminate flooring in my 1950s built house back in 2016 in the small front hallway and discovered brown/black broken tiles underneath. They only partially covered the floor, a lot were already gone. Not realising i broke up the ones that were left, some were still stuck down and it created quite a lot of brownish/black dust as they were quite crumbly. I threw them all away and cleaned up by sweeping and wiping everything. I didn't think anything of it until someone mentioned something recently about asbestos in old floor tiles and it's got me worried now! I've had a look online and they looked very similar to pictures of asbestos tiles. Just looking for any advice on the potential risks?

Thanks
