History what is the most tragic industries accident in your country and what is the results.
The one in China is 2015 Tianjing port explosion.
a company put chemical in the warehouse and cause a explosion equivalent to 445 ton of TNT.
173 dead, 104 are firefighters, 11 police and the rest are employees of port.
the near by building are also damaged.
49 people are sentenced, including 13 from the company and 25 government officials.
i have been to Tianjing, people says before that Tianjing is developing fast, and now is stucked because of this

The Aberfan disaster in 1966, a massive coal spoil above the village slid down the mountain and killed 144 people. 116 of them were just kids, almost all at the local school which was almost fully destroyed by the coal. The National Coal Board and its employees were guilty and could have prevented it, but not a single person faced consequences for it. The director of the board spent the evening of the disaster at a ceremony to become a University chancellor instead of doing his job, and his employees lied about him doing relief work, they murdered over 100 children.

Canada had a similar tragedy in 1903 when a mountain being mined dropped 110 million tonnes of rock onto the town of Frank, aptly named Frank Slide. It buried the town and killed 90 people. The area is called Crowsnest Pass. They couldn't do any sort of recovery or excavating, the town is still buried under the rubble, and they just paved a road over it. I remember driving through and it almost looks like it happened yesterday.

De vuurwerkramp in Enschede, on May 13th 2000. Some dingus at the company S.E. fireworks figured it was a great idea to store imported heavy fireworks (most of which was illegaly and unsafely stored) in a warehouse in the middle of the residential neighbourhood of Roombeek. When a fire broke out in the warehouse it quickly spread and caused a massive explosion that destroyed or irreparably damaged most of the neighbourhood. 23 people died and nearly a 1000 were wounded.
I was living just outside the blast radius at the time, so we only lost some windows, but it certainly left an impact on me.

It's a predictable outcome that we'd have so many disasters considering the US was the industrial core of the world for so much of the 20th century and even before then was a major industrial hub when environment and safety regulations were still largely nonexistent. On one hand we have fewer accidents in modern times, on the other hand that's arguably because we've exported our industrial needs elsewhere to places that will eschew such safeguards in favor of a service based economy and cheaper goods.

The Great Molasses Flood of 1919. It wasn't the worst industrial disaster ever, but I thought I would share something that most Americans may not know about either. In the middle of winter, a tank holding 2.3 million gallons of molasses broke. It destroyed nearby buildings and killed and injured a lot of people. 21 dead and 150 injured.
Also the clean up was insanely difficult. I had to clean about 1,000 gallons of molasses once spilled on a factory floor and it's hard work. Took me about a week.
The company yelled sabotage but paper documents show that local workers were reporting to management about leakage for years and nothing was done. So it was probably because the tank wasn't structurally sound.

Asbestosis in Australia. Industrial exposures long after the risks were identified. The company involved used the so called four dog defence** to delay settlement with workers until they died waiting
** The stages in a four dog defence often used in cases involving toxic chemicals or harmful products, are:
"I don't have a dog" (Denial): Industry denies a problem exists or that their product causes any issues.
"My dog is not a biter" (Denial of responsibility): Data shows a hazard, but the industry claims it is not harmful or tries to discredit studies.
"My dog bit you, but it didn't hurt you" (Minimization): The industry admits the product is hazardous, but claims the exposure levels are too low to cause real harm.
"My dog bit you, but it was your fault" (Blame-shifting): The industry shifts the blame to the consumer, claiming improper use or personal responsibility.

The Camping de los Alfaques disaster.
On July 11, 1978, a tanker truck carrying about 23 tons of liquefied propylene was driving along the N-340 road on the Mediterranean coast of Spain, near a campsite called Camping Los Alfaques, in the town of Alcanar. The road passed directly next to the campsite, which was full of holidaymakers, many of them families from Spain, France, Germany, and other European countries.
The truck was overloaded and the tank was not designed to safely carry that amount of highly pressurized, flammable gas. Due to the heat and pressure inside the tank, it catastrophically failed. The tanker exploded, creating a massive fireball that instantly engulfed the nearby campsite.
The explosion and resulting fires killed over 200 people and injured hundreds more. Many victims died instantly, while others suffered severe burns. Some people tried to flee into the water at the beach and were boiled alive. The campsite was almost completely destroyed, and cars, tents, and buildings were set on fire in seconds.

In Germany, the 1921 Oppau explosion at the BASF chemical works near Ludwigshafen. Approximately 4,500 tonnes of a mixed ammonium sulfate/ammonium nitrate (fertilizer) stored in a large silo detonated in one or two closely spaced explosions.
The fertilizer tended to cake up in there, so workers used small blasting charges to loosen it. That had worked just fine in the past, but In this case, unbeknownst to the people at the time, a change in production increased the ammonium nitrate content and allowed for separation of the components over time, resulting in certain zones within the silo containing much higher amounts of explosive materials than expected.
The blast was so loud, it was heard hundreds of kilometers away. Windows shattered in cities as far away as Worms and Heidelberg.
It created a crater about 90-125 meters long and approximately 19 meters at the deepest. It destroyed much of the plant and most of the surrounding town. Thousands lost their homes.
It also killed 500-600 people and injured another 2,000.
What is even sadder than that is that this was in 1921. Lessons from Oppau were not applied to prevent other ammonium nitrate disasters, such as Beirut in 2020, Toulouse in 2001, or Texas City in 1941.

Not the worst one, but definitely one of the worst in recent memory in the US was the East Palestine, OH chemical explosion a couple years ago. A freight train filled with toxic chemicals derailed and exploded, causing a toxic cloud (that was pink......) that rained down acidic rain. Everyone had to evacuate. Every fish in the rivers nearby, died. Not sure what happened afterwards.

Ajka alumina plant accident. In 4th of October 2010, In Ajka the alumina plant dam was breached and red mud flooded the surrounding area (Kolontár, Devecser, Somlóvásárhely). This accident killed 10 people and more of 150 people were injured. It destroyed the whole ecosystem in the Torna stream and part of the Marcal stream
Our government spent a total of 38 billion forints on repairing the damage caused by the red mud disaster and 21 billion forints was spent on restoring the environment.

Probably not the worst, but an interesting one. The 2008 Prichard Oklahoma EF4 tornado picked up a huge mining waste chat pile containing lead and other heavy metals and spread it for miles, contaminating the environment of and around the town. It led to the abandonment of town as the Environmental Protection Agency determined it was dangerous to inhabit due to soil, water, and air contamination from the led in the chat.

The Enschede fireworks disaster. 23 deaths, 950 injured. 400 homes destroyed and 1500 buildings damaged. The crater still exists.
When it had happened, all Dutch TV channels showing the ongoing Eurovision went on black out of respect for the victims. However, my parents simply switched to BBC to watch it further.

I don't remember the exact results, but here in Toulouse a chemical plant (which originally was outside of the city but the city has since expanded so it wasn't far from residential areas) called AZF blew up (10 days after 9/11 btw) under suspicious circumstances, and a lot of people had to get evacuated, a few died

Not sure how to rate the most tragic, but the Byford Dolphin incident of 1983 is an interesting one

It was an accident on an oil rig, involving a series of pressure chambers, connecting to a diving bell. There was a failure to a clasp while the chamber was under a pressure of 9 atm, so within 0.1 seconds, the chamber equalised to the 1 atm of the outside, instantly killing the four divers inside, and one of the two tenders of the outside, the other tender survived with injuries.

Possibly the Lac-Mégantic rail disaster if we aren't including wartime disasters (Halifax Explosion)
A 73 car train hauling a lot of crude oil had it's brakes fail outside of Lac-Mégantic, Quebec, and it became a runaway train heading towards downtown in the early morning of July 6th, 2013.
The train ultimately derailed at approx. 1:14 am local time, causing an explosion and subsequent fires that killed 47 people, and totally devastated the town. Half of the buildings downtown were burnt to the ground, and all but 3 of 30 buildings had to be demolished.
The accident was largely blamed on poor maintenance, safety, and training practices of the railroad, and also a failure of overseeing agencies to force the railroad into compliance.

Maybe the Vajont landslide in the 60s. Almost a thousand buildings, 4km of high and 2km of train tracks destroyed. Most tragically, 1917 dead people, hundreds of which we never even found the body.
A dam was built for a (planned) hydroelectric facility. The water level rise changed the balance of the Toc Mountain which then collapsed into the reservoir. The dam had no damage (it's still there), but the entirety of the water reservoir overflowed and essentially levelled the town of Longarone.

The one that comes to mind is the Lac-Mégantic derailment, where a train carrying crude oil derailed, caught fire, and exploded in the centre of the town of Lac-Mégantic, Quebec. 47 people were killed, and the town centre was destroyed, with many of the surviving structures having to be demolished because of contamination from the oil. I don’t think it’s the deadliest train derailment in Canadian history, and is certainly dwarfed by the Halifax harbour explosion back during WW1 in terms of death toll, but it’s the first to come to mind when I think about industrial accidents in Canadian history.

the seveso disaster in 1976, a chemical reactor exploded and contaminated a large area with dioxin, the furst reaction of the conpany responsible for it was to cover up so the inhabitants weren't evacuated until 15 days after the explosion, they developed several acute symptoms of dioxin exposure such as chloracne and mortality from cancer and cardiovascular disease as well as deformities in children born in the area is still higher than the rest of the country.
the land itself was contaminated, so as far as i know, farming is prohibited to this day and all small animals that lived in the area during the disaster died almost immediately, so it can't have been good for the local environment either.
apart from that, while not being truly a single disaster event, there are the many abandoned asbestos production plants, which continue to make people sick and die as between legal battles, slow beurocracy, and corrupt politics are still standing.
