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.

Imagine you have a cup made of glass and a cup made of plastic.

Imagine they smashed, and you put your hand in the mess.

You’d probably have little painful shards of glass stuck in your hand, but not plastic.

At a microscopic scale asbestos breaks like glass with lots of tiny tiny shards that can stick in your lung cells. Fiberglass breaks more like plastic at that scale.
