It is a fantastically useful material, except for all the mesothelioma.

[–] SzethFriendOfNimi@lemmy.world 93 points 2 days ago (1 children)

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.

[–] degen@midwest.social 36 points 2 days ago (1 children)

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.

[–] GissaMittJobb@lemmy.ml 53 points 2 days ago (4 children)

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.

[–] ColeSloth@discuss.tchncs.de 36 points 1 day ago (1 children)

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.

[–] psud@aussie.zone 16 points 1 day ago (2 children)

So many people were exposed to asbestos dust in New York when the world trade centre towers were destroyed by terrorists

[–] ColeSloth@discuss.tchncs.de 3 points 1 day ago

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

[–] gerbler@lemmy.world 7 points 1 day ago

This is probably how I'll die tbh

[–] SzethFriendOfNimi@lemmy.world 22 points 2 days ago* (last edited 2 days ago)

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.

Any time you disturb it theres a problem

[–] Flocklesscrow@lemm.ee 8 points 1 day ago

TIL, I'm an asbestos.

"If you or a loved one have been diagnosed with mesothelioma, you may be entitled to compensation..."

[–] psud@aussie.zone 15 points 1 day ago* (last edited 1 day ago) (2 children)

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

[–] DJDarren@thelemmy.club 1 points 8 hours ago (1 children)

The company that founded Wittenoom?

[–] psud@aussie.zone 1 points 8 hours ago

CSR, if I recall correctly

[–] Korrok@lemmy.blahaj.zone 5 points 1 day ago

The same shit happened in Spain

[–] Tar_alcaran@sh.itjust.works 46 points 1 day ago (2 children)

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.

[–] Agent641@lemmy.world 12 points 1 day ago

Mother Gaia does a little trolling

[–] Anticorp@lemmy.world 6 points 1 day ago (1 children)

This is how you know the universe hates us.

[–] psud@aussie.zone 12 points 1 day ago

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.

[–] ColeSloth@discuss.tchncs.de 12 points 1 day ago (1 children)

That and lead in paint and gasoline all worked amazingly.

[–] HelixDab2@lemm.ee 16 points 1 day ago (1 children)

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.

[–] ColeSloth@discuss.tchncs.de 10 points 1 day ago (2 children)

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.

[–] HelixDab2@lemm.ee 1 points 9 hours ago (1 children)

You can absolutely get high octane ethanol-free gas; there's a place near me that sells it. I know that a lot of people with motorcycles use it, because inline four cylinder motorcycle engines tend to be high compression, and motorcycle people tend to be almost religious about not using ethanol. (Which is unnecessary; assuming your motorcycle is fuel injected, the only risk with ethanol is storage for several months at a time with a full tank of gas. If you do that, then you're going to end up with water in your gas, because ethanol is hygroscopic. As long as you keep riding regularly, or empty your tank and run the motor dry before storing it for more than a month, you'll be fine with ethanol in your gas.) I know of at least once place near-ish to me that sells 110 octane ethanol- and lead-free racing gas. Ethanol-free high octane fuels tend to be about 25-50% more expensive than fuels with ethanol.

Avgas is another story. The odds are pretty good from what I can tell that any prop airplane is going to need gas with tetraethyl lead. To me, that sounds like a good reason to remove them all from service in favor of jets, but I think that jets have a higher stall speed, which can be a problem, esp. in backwoods areas.

(Jet-a and jet-a1 are kerosene derivatives, and don't have lead.)

[–] ColeSloth@discuss.tchncs.de 1 points 7 hours ago

Ethanol free gas doesn't mean there aren't any no knock additives. There's several more things besides Ethanol that can be added to gasoline that will increase the octane. Strictly speaking, "gasoline" isn't even one exact formulation.

Short of it is that ethanol free gas just means it's using something else to boost the octane.

If you want a sad rabbithole, look at the cancer rates around small airports, which are often much closer to where people live.

[–] 667@lemmy.radio 5 points 1 day ago (1 children)

While it’s no consolation to these current people, they are trying to make the switch to lead-free aviation fuel. It’s partly a regulatory nightmare, and partly a genuine safety challenge; mandating a fuel change in aviation without adequate research and understanding can result in unexpected engine malfunctions.

[–] HelixDab2@lemm.ee 2 points 9 hours ago (1 children)

unexpected engine malfunctions

On the other side of that is the known problems that lead causes. Seems to me that the best solution is to give everyone a cut off point, and say, hey, when we hit this point, you're going to have to retire that engine, and get one that's known to be good with lead-free avgas. Sure, it's a cost, but that's why you give people time to prepare.

[–] 667@lemmy.radio 2 points 8 hours ago* (last edited 8 hours ago)

They have! 2030.

I’m not sure if it’s a mandate, or a goal, but it’s there.

[–] pumpkinseedoil@mander.xyz 2 points 2 days ago

As long as it doesn't break down it's awesome
