It’s supposed to be it tends to get brittle and fracture creating airborne shards that you can breath in but your body can’t break down and that continuously damages the cells leading to cancer.
Lead in gasoline was a stop-gap solution. If I remember correctly , it was added because we didn’t have the technology at the time to refine gas sufficiently to get the octane levels necessary to prevent pre-ignition of fuel (which causes rod knock) at a reasonable cost. Tetraethyl lead effectively increased the octane level/resistance to pre-ignition. As a side benefit, the lead slightly lubricated the valves and valve seats so that they lasted for tens of thousands of miles, instead of needing to be reground every few thousand miles.
It was a stupid stop-gap though, esp. since the dangers of lead were well known by then.
You’re mostly correct. It was an additive to raise the octane rating and did lubricate. However, it wasn’t a gas refinement issue that caused the need. An octane boosting additive has been needed ever since, right up to today. Now the octane booster used is ethanol, mostly.
Race cars and many airplanes still use lead. We’re still making people dumber. Just at a lesser scale.
It is a fantastically useful material, except for all the mesothelioma.
“If you or a loved one have been diagnosed with mesothelioma, you may be entitled to compensation…”
We are in Australia. The company that mined the stuff was found negligent as they kept selling it for decades after they knew it was deadly dangerous
I also hear that so many times thanks to one of the Brain Blaze (on YouTube) editors
Doesn’t burn, really hard to wear out, you can just dig it out of the ground, easy to shape and repair.
Except it kills people, and it hurts the whole time they’re dying.
This is how you know the universe hates us.
The universe owes none of us anything. We stick our noses into everything and some things aren’t good for us
This one is only really bad because the asbestos companies kept it secret when they found their product killed those exposed to it.
Mother Gaia does a little trolling
Seriously, except for the horrific issues with the stuff, it would be an essential material for various applications.
Its resistance to fire, heat transfer, etc would do wonders for insulation and construction.
Makes me wonder if it could be treated in some way to make it not-so-inhalable. Though maybe we have better synthetic alternatives by now.
As I’ve understood it, the problem is primarily for the people having to manufacture products using it, and at rest it’s supposed to be inert.
Don’t forget about when it’s time to un-make it.
Tearing down old building or tiles containing asbestos is also a huge issue.
So many people were exposed to asbestos dust in New York when the world trade centre towers were destroyed by terrorists
Yep. Probably like 40,000 people.
Except that people don’t always recognize it and end up drilling holes in it or sawing through it
This is probably how I’ll die tbh

Any time you disturb it theres a problem
TIL, I’m an asbestos.
That and lead in paint and gasoline all worked amazingly.

If you want a sad rabbithole, look at the cancer rates around small airports, which are often much closer to where people live.
As long as it doesn’t break down it’s awesome
