Asbestos, It seemed like a miracle stone, and eventually, the ancient Greeks, Romans, and Egyptians all started using it, too.

More than 4,500 years ago, Finnish pottery makers discovered a stone made of thin fibers that mixed really well with the clay they used to make pots. This stone was so strong, and yet flexible, that they could use it to make their pots thinner and bigger than ever. Plus, it was surprisingly resistant to heat, so the pots could hold things like hot metal. It seemed like

a miracle stone, and eventually, the ancient Greeks, Romans, and Egyptians all started using it, too. That rock was what we now call asbestos, and eventually, we found out that it was too good to be true and stopped using it as much. But that took a while. The word asbestos actually refers to six different minerals that all have the same habit, or way that their crystals grow. They’re called asbestiform, which

just means that they grow in long, thin, flexible fibers. That flexibility, plus their strength and resistance to damage by heat and harsh chemicals, made these minerals incredibly useful in industry. The problem is, inhaling asbestos fibers can be dangerous. Because to your lungs, those flexible fibers are more like sharp little shards. You can probably imagine what happens if you breathe them in: they get stuck in the mucus lining of

your lungs, which can make it difficult to breathe. Inhale too many shards over time, and they can cause diseases like asbestosis, or scarring of the lungs, and mesothelioma, a type of lung cancer. The forms of asbestos with the highest health risks are a part of a group of rocks called amphiboles, and what makes them cause more health issues than others comes down to four of their chemical and

structural properties. First, amphibole fibers are smaller, so they can travel deeper into the lungs. They’re also sharper, so they can pierce your lungs more easily, causing inflammation or creating scar tissue. Plus, they’re hydrophobic, or water-avoiding, which can keep them from dissolving in mucus — if they dissolved, they could be coughed up and get out of your system. Finally, they contain iron, which can react with oxygen in your lungs

and damage the DNA in your lung cells. The damaged DNA can then make the cells to divide too quickly, leading to a tumor. So they may be more carcinogenic, or cancer forming, as well. So, how did asbestos go from being the miracle-rock of ancient potters to the scourge of modern industry? Even as far back as the Roman Empire, some 2,000 years ago, historians wrote about slaves getting what they called

a “sickness of the lungs” after working in asbestos mines. And when the first commercial asbestos mines opened in Quebec in 1879, asbestos-related health issues started showing up in medical journals and case reports. One of the first well-studied deaths was in 1924 in the UK. Nellie Kershaw, who’d been spinning asbestos into yarn since she was 13, died at the age of 33 from asbestosis. When Parliament heard about the

case, they asked a doctor known as E. R. A. Merewether to investigate the health of asbestos workers. For two years, he studied 374 workers at an asbestos textile factory. He found that inhaling asbestos fibers caused scarring in the lungs — and 17 out of 20 workers who had been there for more than 20 years ended up with asbestosis. Merewether presented his paper to parliament in 1930, and the

UK started requiring ventilation in asbestos factories a year later. But it wasn’t until 2003 that asbestos was banned throughout the European Union. The asbestos industry in the United States is a whole other story. Asbestos was used a lot during World War II, since it was cheap, strong, and resistant to fire and chemicals. Naval war ships used asbestos insulation, and buildings were constructed with asbestos floor tiles, shingles, cements, and

insulation for pipes. Production of asbestos in the United States finally started to slow down 1979, when nine asbestos manufacturers filed a lawsuit against the federal government. In 1975, they’d paid $69,000 to an asbestos worker who developed asbestosis, and they wanted to be reimbursed. But the government wouldn’t have any of that. Instead, they proved that the companies knew about, and had been hiding, asbestos-related health information for decades. The case got

a lot of media attention, and people started to try to fix the problem by removing asbestos from buildings. But the US still hasn’t entirely banned the use of asbestos. Even so, asbestos won’t cause health issues for most people. Most of the fibers are so tightly bound into another material that they won’t escape into the air unless you’re trying to remove the asbestos. Plus, every year we each breathe about

a million fibers just from the natural erosion of asbestos-containing rocks. So unless you’re an asbestos worker who’s spent a lot of years without a ventilation mask, or you’re an ancient Finnish potter, you probably don’t have to worry about getting an asbestos-related illness. Thanks for watching this episode of SciShow, which was brought to you by our patrons on Patreon.

0MindSwept0 Don’t worry, just do asbestos as you can.
15ironreaver I run pipe in old packing houses around the US. We work a lot with old insulation and there is a lot of asbestos out there still. We are the only ones that mess with it so it goes un noticed and non hazardous.
81coollambo Isn’t carbon fiber dangerously the same.
Adam Miller No shitting you, i saw a “mesothelioma “ commercial before this video. #illuminati
akshit parikh what’s asbestos?
Amalia Grassi Really?  Probably won’t develop asbestosis anymore?  Have you considered the growing phenomenon of urban exploration?  (Urbex) hugely popular amongst the younger generation?  It’s frightening.  And how about secondary risk of developing the illnesses?  Mum’s doing their son’s washing etc?  I’m very concerned about it.
Amanda Appels The most important thing to remember about this video is that if you or a loved one has been diagnosed with mesothelioma, you may be entitled to financial compensation

bdbdbd Chemist used to work a lot with asbestos but that has stopped. We still uses tonnes of silica though which is just as nasty and causes the same kind of symptoms called silicosis. It’s like a very fine and sharp form of sand or glass.

Camaco Consulting Correction from [3:50] claim “Asbestos won’t cause health issues for most people” . Indeed it does and very seriously. Not only asbestos removal workers but also the nearby public from any activity disturbing materials with asbestos is at risk. Refer to the Occupational Health and Safety Regulation 2017 from Australia (Chapter 4, part 4.4-Asbestos). This is one of the countries that fortunately brought into legislation a total ban on the substance and faces the problem now with more transparency than other jurisdictions where is preferred to deny it or hide it.

Deon Van der Westhuizen Asbestos is a group name for some minerals.  Whites asbestos was used in about 95% of applications worldwide.  This is also the least dangerous asbestos.  Blue asbestos is the dangerous asbestos.  Luckily it was used very little.  In the UK any asbestos are seen as way more dangerous than nuclear bombs.  In the more practical USA they are not afraid of white asbestos.  That is why they are still using it.  The UK asbestos scare was driven by unscrupulous contractors and health and safety consultants.  At this moment crooked contractors and consultants are going through schools with a magnifying glass, looking for any asbestos.  Of any kind.  Just so they can land another massive overpriced contract to remove it, at the taxpayer’s cost.  While in the USA they know it is the safest to just leave this bonded asbestos alone.  Do not drill into asbestos, or do not sand asbestos.  If you must, do it in the presences of water.  Water will capture and nullify the danger of white asbestos fibers.  Breaking asbestos is not a risk.  Even if you eat it.    I have been working with bonded white asbestos for 20 years, as a roofing contractor.  Shingles, fascias, gutters and roof sheets.  Even in the pre dust mask era.  And I am still healthy.   Plenty of farmers in arid areas all over the world still rely on asbestos tank and piping for drinking water.  You go try and tell them it is unsafe to do so.

Dollar Diva Marry me
Don Wald Only bothered checking after a woman died! Men are disposable?
Dummy Enigma I’m a construction worker. Sometimes we do remodels of old buildings where the asbestos is in the floor glue, walls, and ceiling tiles. Usually they know about it and abate the asbestos before hand. Sometimes though they don’t know or say “there could be asbestos so be careful” and abatement comes later. is that super dangerous?  could I or a loved one who has been diagnosed with mesothelioma be entitled to financial compensation while we die?
Emery Smith I got a Mesothelioma as before this video haha
Eric Taylor In I think 1986 or 1987 they closed the library in my high school because asbestos was discovered. They had the library closed for 3 months and spent millions of dollars to remove it, even though leaving it be until the summer would have had no negative health concerns.     Do you have any idea how inconvenient it is to have your school library closed for most of the school year in the days before the internet was easy to use?
Eric Weng Wow, humans have a knack for using toxic materials in everyday items. Lead pipes, Paris green, asbestos houses, and I’m positive I read about some radioactive toothpaste, or maybe just radium being considered healthy.

Geek To Me Think about all those asbestos lawsuits involving workers who smoked cigarettes for 35 years, have a 0/1 B-Reading, and who all claim they developed asbestosis from the occasional cutting of asbestos gaskets from the only manufacturer who just happens to not be bankrupt yet only had 15% of the market… it is legalized extortion.
Glyn Williams I am hoping The Thailand health minister will review his decision not to ban asbestos, (he does not see enough evidence that it’s dangerous)

Goslin Love how the ad was about how asbestos in homes kills people. Is that something the people who run the account can control, or was that the algorithm?
happensq1 Asbestos
Harley Tutor the pros out weigh the cons i my opinion. unless you actually work with the stuff, it more than likely wont effect you. if you work with it, wear breathing equipment. cheap, durable, flexible and naturally acted as an insulating and fireproofing agent. use it in homes for fireproof insulation again. if its blocked off with drywall, it shouldn’t harm anyone, and might give the fire department a little more time to get to your house before it’s a complete loss. seriously, everything gives you cancer, or kills you in some way. nothing is 100% beneficial. everything has a downside or side effect.

Justin Hillery True story, in 2010 the marine corps was issuing asbestos gloves to machine gunners so they could change out hot machine gun barrels in combat without burning their hands. In 2006 the navy was conducting asbestos ripout operations in the galley of a building…WHILE WE WERE EATING…and the plastic sheeting around the work area was full of fist sized holes and signs that read “danger, asbestos removal in progress”….gotta love it

Kye Talks The science museum in my city (which is the capital of my freaking country) has been closed for the better part of a decade because they are removing the asbestos…… kinda ironic when you think about it.

LORCAN MANANTAN now i can breath
louiscypher1001 4:03  Interesting.  Does the math work out for that?  I’ve seen my fare share of fiber count reads on asbestos jobs and even when I adjust the math for the ambient fiber counts out side of the areas that have asbestos being disturbed the numbers don’t equal a million fibers per year   And those fiber counts are for all fibers they aren’t acid reduction counted. If i’m wrong lease correct me. I’m just trying to figure out his statement there.  https://www.atsdr.cdc.gov/phs/phs.asp?id=28&tid=4
louiscypher1001 So, the CDC says we get about 10 fibers per cubic meter of air and hour.  I think your numbers are wrong on your statement of one million fibers.   https://www.atsdr.cdc.gov/phs/phs.asp?id=28&tid=4

Paul Drake My elementary school in the 1970s had asbestos in the walls and ceilings, the city decided the safest thing to do was leave it all encased and not try to rip it out. Then when I was in 6th grade our town flooded and they ended up gutting the entire school to renovate it. It’s since been torn down.
Paul White my stepdads dad died of mesothelioma leading from asbestosis after only having been involved with removing some asbestos from his own hotel (only a few rooms) so it does not take long periods for it to affect you in a terminal manner. this was over maybe 2 months, not long-term exposure.

Wireline We had a ‘professional’ asbestos removal team come in to take away some old garage panels. Without any masks, they smashed the panels in to successively smaller squares with powder flying all over and then wrapped them in plastic.
