The Biggest Disaster You Never Heard Of (PEMEX LPG Explosion '84)

A commercial airline pilot thought a nuclear bomb had gone off - that's how big this terrible explosion was. Hundreds killed, thousands injured, and yet it remains relatively unknown outside of Mexico. This is the story of the PEMEX LPG storage explosion...

Mexican here, I heard of it, I was around 10 years old, but I recall the news about it and seeing some home video footage taken from far away in the early morning by some distant neighbors, maybe 8 or 10 kilometers away from the site, the area was a very-low income area so year, imagine a fireball hitting your home then a shockwave.

[@chatteyj]

Same, thought it was going to be that fossil fuel tanker explosion in southern Spain, I was wrong.

[@alannummy2148]

Great one, but just for those that don’t know those small propane cylinders virtually never explode in a house fire. The overpressure valve, commonly called the “pop off” kicks in and vents the gas. The result is a loud, screaming blowtorch of flame but no earth shattering kaboom. The small tank in the video didn’t blow either. Can’t see to be sure, but the burn marks around the handle and across the top look like the overpressure protection worked as designed.

[@George-vf7ss]

Bingo, pay the man.

[@jacekatalakis8316]

The USCSB found that at least post 84, those valves at least in the US were pre Praxair blast (Which Raven's EYe should cover IMO?) were set up to go off at lower pressures than they were meant to however and were weakened each time they were used as per the CSB's vid on the Praxair blast

[@alannummy2148]

@@jacekatalakis8316 That makes a BLEVE even less likely. It was an issue at the St Louis fire because there were hundreds of cylinders containing different gases all stored in very close proximity that suddenly got exposed to a lot of flammable gas fed fire. In a normal house fire, a 20lb cylinder venting early just makes us firefighters jump and briefly soil ourselves a little sooner.

[@elliottprice6084]

I'd never heard of this disaster before, but while watching it, a word sounded familiar- Pemex. It's shocking that so much about this tragedy is hidden in the mist of time. Another disaster that involved Pemex was the Guadalajara in 1992. A gasoline leak caused a series of explosions in the city. Like in this disaster, the death toll is given as much lower than what it was. Why haven't Pemex learnt from so many bad disasters over four decades?

[@CatMom-uw9jl]

That’s the one! I knew I’d heard of Pemex before

[@reachandler3655]

When you were describing the site I was thinking that, ideally, you'd live as far as possible from it... failing that, right next to it, so you don't have time to know you're dying! Why the frack did they continue pumping to the site for 40 minutes? 🤯 Great presentation, thankyou.

Capitalism

[@PrezVeto]

​​​​​@@cjthebeesknees Pemex (short for Petróleos Mexicanos) is 100% state-owned, fool, like USPS or Amtrak. They have a terrible record because they have a legal monopoly on petroleum and natural gas extraction, refining, and sale in Mexico. If you've ever been to Mexico you may notice that all the gas stations seem to be owned by Pemex. You'd be right. They literally _all_ are. When your only competition consists of the bicycle and walking shoe industries, you get basically the same amount of customer business regardless of how well or poorly you operate. Capitalism isn't perfect because humans aren't perfect, but competition and the profit motive best incentivize humans to be better.

[@AussiePom]

Well in what are now regarded as first world countries in the not to distant past human life was cheap. For before WW2 there was no universal healthcare, no paid sick leave and no pensions. If you got very sick you either got better on your own or you died. People worked themselves into an early grave so no need for pensions. If you got injured at work and couldn't work and you went on the parish relief. Usually your wife divorced you simply to find a working man to feed the numerous kids you had and he would add his own and if your kids were older and working then they helped support you. Many people fought pitched battles with police to fight for better working conditions and better remuneration that the employers did everything to avoid for it cut into their profits. These days many young people take it for granted and want to give away all these hard fought for rights. Employers have moved overseas because they know they can make huge profits at the expense of the people who make things for them so the employer class has not changed it's mindset. When the Chinese get too expensive for them then they'll moved to another country to exploit their people for their sacred profits. One African country still has child labor what the now first world countries had in the 18th and 19th century before it was outlawed.

[@glennzanotti3346]

I grew up in a refinery town in Texas. I do remember this explosion. LPG (propane) is heavier than air, so the gas cloud would have hovered near the ground, and spread until it found an ignition source. LNG (liquified natural gas, or methane) is lighter than air, and would have risen upward. If it found an ignition source, it also would have exploded, but it probably would have been less catastrophic. That propane near the ground could have spread all over the facility before igniting, causing the subsequent explosions described in the video. In the US, just as in Mexico, it is poor people who generally live closest to the refineries, chemical plants and storage facilities. That makes it easier for governments and companies to play down the death toll. It is easy to pretend poor people didn't exist. Cancer rates among the poor living near the refineries in my hometown have high rates of cancer, but nobody cares.

[@zetectic7968]

To allow housing to be built so close to the plant was criminal. Not have even rudimentary safety feature meant the negligent should have been held to account but I'm sure that never happened.

[@bebolino100]

Here in México this housing was without any regulation. First, the surrounded area of the plant was occupied by people that emigrated from rural places to the Mexico City Metropolitan Area. The houses were selfmaded.

[@P_RO_]

Often plants, airports, racetracks and the like are intentionally built out from towns to avoid problems, but often the towns grow to encompass them. Sometimes the new residents who knew what was already there complain enough to get those places closed down when it was their own fault for the problem affecting them. Governments don't care about anything until it might cost somebody the next election, then they choose whatever solution will get them the most votes.

[@ItsJustLisa]

My mom had a coworker for many years who was from Mexico City originally. Her parents still lived there when this happened so I remember Elia telling us about it. Her father was a physician and hadn’t yet retired when this happened. I think he ended up having some of the victims from further away from the plant as patients.

Anyway, your video on this is very well-done, & I'd love to see other disaster-themed channels cover the topic more. :-) Great job! ❤

[@joeylawn36111]

In 1992, something similar happened in Guadalajara, this time with gasoline instead of LPG. An underground gasoline pipeline ruptured due to galvanic corrosion, flooding the sewers with gasoline and fumes. It found an ignition source, and there was a massive explosion. Over 200 people were killed (probably a _lot_ more), over 500 injured, and damages were between half a billion and 1 billion $'s.

[@peronik349]

when political expectations, such as elections, interfere with the reality of the facts about a catastrophe (like the death toll or the responsibilities of elected officials) we ALWAYS end up with stupidities. in this kind 2 French cases come to me: there was the eruption of the Montagne Pelée in Martinique in 1902, despite the very clearly evident threats the municipality prohibited evacuations because of municipal elections: the catastrophe took place 4 day before the election, the death toll was "around" 30,000. or the catastrophe of the “courrière” mine in 1906 the official count was stopped at 1099! but 300 to 500 other minors were never seen alive again. the realistic estimate seemed to the authorities of the capital as politically "unthinkable" so the account was stopped.

You could very well do a mini series on all the disasters Pemex have been involved in over the years or alledged to have been involved in. IMO one of the reasons this isn't well known is both Bhopal and the 1985 Mexico City earthquake happened and both overshadowed the Pemex explosion however.

I've had the privilege of working at a high end plant that (luckily for me) didn't focus on just 1 product.. we were the guys you come and ask for solutions to a problem you've encountered and need chemical engineers. It was BEYOND fascinating! .. and safety was taken SO seriously that we were very proud of our relatively clean record. I'll never understand shareholders and CEO's etc not taking workers safety seriously.. like _oh yeah, there's Billy. He's the best at was he does, we've spent 100's of 1000's of pounds on his training.. he's perfect at it now and production is breaking records. Now let's look the other way when they say they need to be safe.."_

The biggest disaster most people haven't heard of is also the worst industrial accident (and third worst flood) ever: Banqiao Dam. In 1975 it failed, setting off a chain reaction which then destroyed dozens of other dams. In the end, it made millions of people homeless and killed *at least* 25,000. But this occurred in China, so getting information about it is still difficult.

I am always impressed at the abysmal safety record for EVERYTHING in Mexico. If there is a way to put absurdly numerous people in great jeopardy and then MAKE SURE THAT JEOPARDY BECOMES TRAGEDY.... well you will find that happening in Mexico. This type of negligence TOWARD THEIR OWN populace shows how little ALL of Mexico's political and business class care about human life. And yet tourists world wide flock to Mexico and they become part of the "AT RISK" population. The safety measures that are part of COMMON SENSE for the rest of the so-called First World countries SIMPLY DO NOT EXIST IN MEXICO. Life is cheap in Mexico and the citizens know this and seem to accept it as "fate". At 9:35 Jose' Hispanosa verifies this attitude. PEMEX HAS NO REASON TO IMPROVE THEIR SAFETY RECORD SINCE IT MIGHT COST THEM A SMALL AMOUNT OF MONEY AND MURDERING MEXICAN CITIZENS IS THE COST OF THEM DOING BUSINESS. People everywhere get treated the way they deserve by business and politicians. Very sad but very true.

[@PrezVeto]

To understand the rich history of safety failures by Pemex (short for Petróleos Mexicanos), it must be understood that it's 100% state-owned, like USPS and Amtrak are in the U.S. Having a legal monopoly on fossil fuel extraction, refining, and sale in Mexico, the people who run Pemex have only political pressure and conscience-no profit motive-incentivizing them to do better. The CEO is appointed by politicians and any profit goes to the Mexican treasury. Its executive suite is a source of lucrative patronage positions with which politicians have paid off their friends. Their primary competition consists of the bicycle and walking shoe industries, so they're not very concerned with keeping their customers _wanting_ to do business with them. It also means that trying to recover damages from Pemex in court is basically the same as trying to recover them from the Mexican state. As it does everywhere, the law serves the state more than any other party.

Note: Amtrak is not 100% state-owned and the United States Postal Service is not a monopoly; thus, neither is an entirely fair comparison with Pemex, which is both.

About the "combined explosive power" of LPG in this facility - your comparison is rather inaccurate, as hydrocarbons ARE NOT explosives per se. With any of these (TNT, ammonium perchlorate/ nitrate or such) it is OK to make such parallel, but LPG cannot explode on its own as it lacks any oxidising agent. Only when mixed with air (oxygen in it) it can explode, but this is not what it happens in situations like this one here - only a tiny portion of LPG actually "exploded", the rest just burned - rather fast, but nowhere even near the speed of the explosions of LPG-air mixture. Which itself is a rather slow deflagration "explosion", not the "proper" explosion of any high explosive - and that makes A LOT of difference in destructive power. Think of pushing a heavy door, fast, with your hand, vs kicking it hard with your foot - vs. using shotgun shell operated breaking ram. The first method won't do any damage, and this represents "fast burning off" of released LPG after the initial explosion (even if that was secondary one). The kicking represents deflagration - it may damage the door, but only so much. The ram represents true explosion, and it will absolutely wreck the door. So, three different results, the total energy involved is "about the same", and the difference is caused only by the speed the energy is delivered. PS: - and then there's this silly mixing of physical rupture of a propane-butane tank (aka LPG cylinder) due to, say, heat boiling off the LPG inside too quickly (as may happen in the case of fire) AND the subsequent explosion of released propane and butane vapours. And such inaccuracies in your videos do put me off of them. Also - that "pumping of LPG from refineries" might "continue" not because someone forgot to shut off the supply (or never thought of it in the, erm... heat of the moment), but simply because the pipelines themselves hold certain volume of whatever medium is being sent by them, so even if someone shut off the supply immediately (which might not be possible due to technical reasons and/ or limitations), the LPG already in these pipelines would continue to be released "at the other end" of it, now ruptured. And then, fires WERE NOT "brought under control" - it looks like all LPG there just burned off, so the bonfire just ceased to burn.

Compare this disaster to the 1988 PEPCON disaster which had the advantage of occuring out in the desert ( at the time) claiming only 2 lives ( a supervisor and disabled person at PEPCON who couldnt evacuate fast enough) even though their product, rocket fuel, produced a massive explosion- caught on camera from a nearby mountain.

Goverment agency's are never good. No madder what country they are in. WE THE PEOPLE is not included with goverments. Any goverment, any where.

Haven’t there been like, 4 mass casualty explosions caused by PEMEX being an absolute joke of a petrochemical company?

I saw the aftermath of the Algerian gas liquidification plant Skikda in 2004, scary stuff.

BLEVE pronounced BLEV-ee.

That person in the white pickup truck at the end seemed to not know that reversing or uturning was an option

I grew up in Mexico at the very end of the one party dictatorship it had for decades and I knew about the monopoly PEMEX had until relatively recently, I may have heard of this incident but I’ve never known the details though.

I'm surprised there are enough Mexicans left in Mexico to run a plant this size. Most of them are here working for Google and Spectrum.

There are things like "LCD display", which do not make sense, since the D already stands for display. Same with BLEVE. It stands for "Boiling Liquid Expanding Vapour Explosion". So, if you say or write BLEVE explosion, that is kinda stupid, is it not?

I saw this couple of years back. It was discussed while explaining the Pemex Guadalajara story Sorry. Still watched it again
