We've Become Masters of the HAZARD DIAMOND 💠⚠️

[@naxmorvigatore4168]

I think a hazard diamond full of 4's with "awe" in the white space would make a fucking amazing new Modern Rogue shirt

[@Clockdistrict]

YES!

[@tarper24]

I want one!

[@luketurner314]

Or 5's for "off the charts" awesome, also to be clear that it is not an actual hazard, so the authorities won't get upset for using a hazard diamond inappropriately

[@Q1745]

@@luketurner314I’d buy one!

[@legoobi-wankenobi3080]

This feels like something their insurance policy would have required of them. They do a LOT of stupid, dangerous stuff.

[@MalcontentRobot]

[@KimTaura]

Or their attorney... 😅

[@ChicoTunda]

lmao. Yeah this wasn’t a video idea. their insurance people were like “we want video proof that you have studied the hazard diamond.” and they just decided to upload it here as well.

[@billiam247]

That's awfully presumptuous of you to assume that anyone would insure these shenanigans.

[@Texfire]

I hate to have to say it, but Jason was correct the first time, NFPA does indeed stand for National Fire Protection Association, as in "protecting people, pets, and property from fire". NFPA 704 diamonds aren't intended for transport, but are a way of marking fixed facilities for workers and first responders to alert them to stored hazards. It's intended to be visible at distance, and very general as to the form of the hazard. On site MSDS (Material Safety Data Sheets) should be stored and made available for much more specific info on the hazard(s) placarded.

[@porterplayer1]

The NFPA diamond is the NFPA 704, it is mainly used for stationary objects like on doors to rooms chemicals are stored in or bigger tanks that are not really mobile. For stuff in transit they end up using the Department of Transportation placards which classifies the hazard in one of 9 classes and will at time have a 4 digit number that will help identify the hazardous material in transit. First responders can use an ERG (Emergency Response Guide) using just the class of hazard or even look up the material by the 4 digit number. That being said Hazardous Material Techs for the fire departments in my area say the ERGs are good for the first 15 mins for the initial response but then use there other resources to respond from there.

[@omega1787]

Also IATA and IMSA Dg regulation

[@stephenphillips2547]

From someone who went through HazMat training with a fire dept: the white diamond may also have a pictogram with one of the 9 classifications of Hazardous Materials

[@humanoid251]

I started working at an oil refinery almost a year ago now and these hazard diamonds were the first thing I had to learn. And like you said learning what these meant felt like I was unlocking some ancient secrets not worthy of mortal eyes. What’s really cool is that during a safety training I had recently, I learned that the DOT puts out this emergency response guidebook that uses the hazard diamonds as well as chemical ID numbers to help identify potentially hazardous substances. So people like myself who know how to use this book can actually assist first responders in the event of an accident by identifying hazardous substances and relaying any important information about them which ranges from the basic stuff on the hazard diamonds (flammability, reactivity to water, etc) to surprisingly specific info like whether a substance is shock sensitive, flammable around electricity, whether it’s more hazardous during the day vs night, how big of an area to keep clear around it, etc. It’s really fascinating stuff

[@Laevetainne]

Same

[@CPFitzgerald]

Would not have thought about UV reactivity as a hazard consideration, but that does make sense for DOT safety regulations

[@HaloGT1]

8:50 TNT is relatively non reactive fresh, but it degrades over time. After a while, it becomes very reactive and iirc can even explode if it came in contact with the moisture in the air

[@CK-ceekay]

Brian might be thinking of C4, that's super stable right? Like you need a blasting cap to detonate it

[@ICantThinkOfAFunnyHandle]

​@@CK-ceekayyou are indeed correct, plastic explosives (such as C4) are valued highly because they can only explode when you want them to (with a blasting cap or other form of detonator).

[@bubsyfinnigan4462]

Shiet, I learned that from LOST, when that one dude blew up cause he was carrying 130 year old dynamite.

[@starfirebird3099]

I followed a hazard sign blog on tumblr a few weeks ago and learned about this; I also work with methanol and the container for it has one of these symbols (1 for health hazard, 3 for flammable, 0 for instability)

[@saudade7842]

The reactivity part isn't just how likely something is to react, but also how energetic that reaction might be. So you could have something that's about as hard to set off a ammonium nitrate (a three), but obscenely violent when it goes boom, so it's a four

[@andrewmirror4611]

And how dangerous the stuff that goes from the reactions is, like sure from nitric acid you get nitroglycerine, flash cotton, lots of stuff, but just by default, NO2, super hazardous, extremely easily produced from nitric reactions, either 3 or 4 on the health hazard scale, but nitric acid and nitric stuff by itself, not nearly as health hazardous, like 2 or 3

[@bartman64]

Thanks for the refresher! I was staring at one of these just yesterday while working on an acid feed pump, and thought “I should know what that means”.

[@phoenix77770000]

This diamond isn't the preferred method anymore. The GHS or global harmonized system is preferred as it is the same across the globe. This diamond is only used in the USA.

[@stephenwilliams163]

My neighbor is a very retired truck driver. Just yesterday he was telling me a story about the time a truck hauling lacquer thinner exploded right front of him in the middle of the interstate. As a story it seems both plausable and embellished.

Everytime a Modern Rogue video drops, I wait until it’s lunch/dinner time to watch it. I’ve been doing this regularly for a long while that it’s got to a point whenever I get the notification of a new MR video I automatically get hungry. Modern Rogue’s Pavlov experiment?

Hey, you two (and team), thank you for the wonderful content. I envy that you get to do this for a living, but insead enjoy your product

[@Tobi2x4]

I've seen these all over, but never knew what they meant. Like you said with the hobo code and the utility graffiti, it's like unlocking a secret code. Definitely gonna keep an eye out for these diamonds in the future. Also, the Bebop reference was beautiful.

[@RyuPlaneswalker]

I can't see the fire Diamond without thinking of an early joke from the Schlock Mercenary Webcomic. "Is it safe to have all those Hazardous Chemicals in the same lab?" "It's not even safe to have all those Hazard Signs on the same door"

[@AndyPate72]

Fellow Schlock fan her I appreciate your reference :)

[@Pigeon__Man]

You could also do the placards with their different numbers that identify hazmat that's being transported. Along with that there's the Emergency Response Guide (ERG, which has a free app) which is a quick reference to each number, what it is, and a rough guide on how to respond to it.

[@pamdrayer5648]

2:05 That makes so much sense, I thought the same thing as Brian. 8:05 The world's scientific inaccuracies have gotten to him. 8:56 1-Diazidocarbamoyl-5-azidotetrazole (azidoazide azide) is a 3-4-4 n the hazard diamond.

[@EdwardIsMyName]

TNT is very reactivate, unlike c4, which you could light on fire without it exploding.

[@TheBigburcie]

It's also not used much these days because it's unstable. The "dynamite" sticks you might see at a mine is generally not TNT anymore

[@HanMasho]

The Cowboy Bebop and relatively obscure Simpsons references made me feel like this episode was made just for me.

[@TheAgentofEnigmas]

This was a very informative and fun episode. I love these kinds of episodes.

[@kurry42]

tnt, trinitrotoluene, is a 4 on the reactivity diamond because of it's ability to explode under heat or impact application, you guys were thinking of dynamite, which is the safer version of nitroglycerin

[@willthewise420]

Thanks for all the funny moments and great content as always, MR crew 🎉

[@Qaos]

About the TNT thing, a 4 on the reactivity means "may detonate at normal temperatures and pressures", which is why it gets that number because it doesn't need high heat or an impact to go boom.

[@darrellmora1319]

Hey, Squarespace! Hope you were paying attention, 'cause that was easily the best ad they've ever done! ROFL

[@Donald.Archer]

Pretty interesting, but here in South Africa, we don't have that. We have multiple different LARGE stickers that say what is in the tanker, eg corrosive / explosive / flammable, with a bunch of extra information next to it. It is a pity that a lot of these "standards" are not international, and only regional.

[@SendarSlayer]

For trucks around the world you're likely too see a set of massive placards with better info. Hazard diamonds are more likely to be used in fixed locations, and there will be a stack of info of what is where at the head office and reception or emergency entries.

[@rexmcstiller4675]

The EU have a diffrent system. Its a orange rectangle with two fields. In the lower one is a 4 digit long number of the exact stuff thats in it. On the upper filed it´s a hazard number with is two to three digit´s long. Every number stands for a group of hazards and if the number is doubled it extra dangerous. 2 are gases; 3 are flamable liquids; 4 are flamable solids; 5 are oxidizer; 6 are poisonous or contagious; 7 is radioaktiv; 8 is corrosive; 9 at the firs digit is dangerous for the environment; 9 at the second or third digit is the danger of spontaneous violent reactions; 0 is just an placeholder for the second digit and X is a danger reaction with water. The first number is always the main hazard. For example: Diesel have the number 30 and gasolin 33. Arsenic would be 60 and arsenic acid would be 66. Lithium would be in the top field X333 and in the lower one 3433

[@EthanLamoreaux]

[@dchall8]

Grim facts: in 1967 all three Apollo 1 astronauts died in an oxygen fire inside the Apollo craft. Four days later in San Antonio, two USAF airmen died in an oxygen fire during a test. Electrical shorts were the cause of both fires. In an oxygen saturated environment, several things happen. One is that things deteriorate/oxidize simply from the amount of oxygen in the air. In both cases above, the wire insulation used at the time became brittle and cracked allowing bare wires to be exposed. Another thing that happens in oxygen rich environments is the flash point of common items drops from many hundreds of degrees down to room temperatures. So a piece of oxygen saturated wood located 10 feet away from a lit match could burst into flames. The solution NASA picked to move forward was to continue using high oxygen content but lace it with Halon gas in small percentages. Very small percentages of Halon prevent fires from happening under almost any conditions.

Arguably, the point at which you split water into hydrogen and oxygen - it is no longer water. Also, water is not flammable at all. It is already in a low-energy state. And if you make paper wet, you can only set it on fire by first evaporating off the water. Your teacher was just being a knob. I've had similar experiences.

[@gdude2775]

TnT is nitroglycerin mixed with a substance to make it much more stable.

[@EggplantHarmesan]

TNT is Trinitrotoluene not nitroglycerin. Nitroglycerin is used in Dynamite.

[@gdude2775]

@@EggplantHarmesan you're right. I mixed up the two.

[@DeliveryMcGee]

No, that's dynamite. TNT is unrelated, MUCH more powerful, and wasn't used as an explosive for decades after it was discovered because it wasn't sensitive enough, it takes a hell of a bang to get TNT to do anything. That's why it started being used as an explosive -- older, easier-to-set-off explosives (like anything containing nitroglycerine) didn't work in armor-piercing shells, they'd just detonate on contact. TNT was stable enough to take the shock of punching through a foot of steel without going boom.

[@DeliveryMcGee]

Red sticks (in reality wrapper colors vary based on brand and potency) = dynamite = nitroglycerine = be somewhat gentle with it. Waxy stuff that looks kinda like caked-up brown sugar, that you melt and pour into an artillery shell = TNT = do whatever you want short of taping a stick of dynamite to it, it DGAF.

[@chemistryofquestionablequa6252]

​@@DeliveryMcGeeTNP/picric acid has a similar story. It was originally used as a yellow dye that could permanently dye silk and other fabrics. The problem was when it was stored in contact with metals such as lead forming sensitive primary explosives like lead picrate. Ammonium picrate/dunnite is so insensitive that it was used in armor piercing shells prior to TNT.

[@iWhacko]

was the radioactive one,, Uranium?? please provide the answer

[@CK-ceekay]

A good fun episode

[@gabriel199714]

Brian, your teacher was right, water is flammable, more specifically, ocean water is. When ocean water is superheated, meaning it gets stupid hot stupid quick, it can sublimate, causing self electrolysis, essentially the heat the water recieves is so intense it causes the electrons on the H2O molecules to "bend" its molecular structure into a shape that allows for electrical current to flow and since heat is just motion, the sublimation produces electrolysis, releasing small amounts of hydrogen that will combust as soon as its exposed to oxygen. However, this process has not been observed to occur on non man made/influenced events, as the amount of heat necessary is too big and needs to be released too fast, this has occurred in ocean nuclear bomb testing sites, that's the only reason we know this happens. So hope you dont get nuked cause you're 70% water 👍
