Why is asbestos so much more dangerous than other ‘sharp’ dusts like fibreglass?

So asbestos is super dangerous to your lungs. It’s tiny, and sharp, so your lungs can’t remove it using mucus etc as it would with other dusts/particles.

*That makes sense.*

But what about fibreglass insulation – it’s tiny little super sharp glass fibres that (in my head) aren’t much different to fibreglass.

What about fine sand, or even diatomaceous earth which is famous for its ability to kill bugs/insects BECAUSE it’s super sharp on a micro level?

 

^For ^the ^flair, ^not ^sure ^if ^this ^is ^a ^biology, ^physics ^or ^chemstry ^question. ^I’m ^hoping ^’bio’ ^is ^OK.

^I ^just ^finished ^insulating ^the ^loft ^with ^my ^father-in-law. ^I ^wore ^a ^respirator, ^he ^didn’t ^(too ^’proud’?) ^- ^I’m ^fine, ^just ^itchy ^skin, ^but ^he’s ^had ^a ^bad ^cough ^for ^a ^few ^days.

People have given very good answers about asbestos but please don’t play loose with fibreglass. Sure, less dangerous, but it still can cause severe skin irritation as well as long term lung and eye damage.
