@@BengalBoy16 yeah I can totally understand that. But if this is easier and better for him and his time; purely in my own opinion we should just let it go. It's either that or he hires someone to make subtitles which is probably harder and more expensive, but that would return his voice and maybe combine his two channels together.

Explosive sodium reminds me of something that happened in college. When I was in high school chemistry, we put a sliver of sodium in a large beaker of water, on the bench, to watch the reaction. We added phenolphthalein to see the formation of sodium hydroxide. I told my college Gen Chem professor about this and he thought it would be a good demo for class. He used a chunk of sodium and a smaller beaker, held in his hand as the reaction progressed. The sodium popped and flared twice, the second time louder and more intense than the first. The entire bottom of the beaker cracked off and fell, spilling pink sodium hydroxide on the floor and leaving an "oh crap" look on the professor's face as giggles spread through the class.

You could send a firefighter on a million seminars and expert training from the experts, two minutes later there's an alkali metal fire, he's still going to be using water.

[@cdhewko]

To error is human. That's true. No amount of training or knowledge can protect us from that. It only reduces the chances of carelessness. When things change quickly, the group often chooses most practiced methods instead of using the best solution. They see a fire, the first responders to the scene misidentify it, and... It's all very logical if you think about it. A, B, or C fires were/are far more common. D fires typically weren't so until the technology made it more common. Logical mistake.

[@jameswalley2500]

As part of my career path, I got to teach inexperienced construction workers about fire safety. Namely about the different types of fires and the extinguishers needed for them. A memory trick I used often was this: Stuff that burns to ash (wood, paper, cloth) gets the Class A. Liquids (like oil, gasoline, etc,) boil just below the flame and get the Class B. Fires around electrical current get the Class C. Metal fires are Damned Hot and get the Class D. Kitchen fires get Class K. Its worked well enough to increase the quiz scores.

[@neon-john]

In the places I used to work where other flammable metals are worked with (U and Pu), our Class D extinguishers contains finely atomized copper and are pressurized with argon. This powder works in 4 ways 1) it is very fine so it packs in tightly. 2) it is very dense and so packs in tightly, depriving the metal of oxygen 3) It has a low melting point relative to these two metal. Liquid copper floats on these metals, eventually depriving the burn of oxygen. 4) it is very heat conductive so it cools the burning metal to below is fire temperature. Fortunately I never saw a flammable metal fire myself, but I've watched several training films on how to put out a fire. It is almost instantaneous.

[@kenbrady119]

Thank you for this public service ad. "people who work with magnesium or other combustible metals" include millions of us who rely on lithium batteries, which can turn into incendiary devices if they are cheaply made and/or not properly maintained and monitored. Thank you, seriously! I'm a biochemist with much knowledge of inorganic chemistry, and I learned a lot watching this.

[@yugbe]

Back in the 90s, I was part of a fire department. At a fire we were called too (Foxworth-Galbraith wearhouse) there was a magnesium storage. Most of the place held wood, but the moment the fire got to the magnesium storage, we had to cut all the pumps and just let it go. It was amazing and terrifying at the same time. There was nothing more we could do. We were there with departments from other counties.

One of my biggest surprises was a gas barbecue that suddenly lit up like a flare when I was preheating it to sear some steaks. I found out later that that barbecue had been recalled, because of manufacturer thought it was a good idea to make this barbecue out of a lightweight alloy that he had gotten as spare metal from an aircraft manufacturer. The metal was a magnesium aluminum alloy. All I could do was stand there with my hose and spray the wall and the House nearby it and the ground around it to keep the fire from spreading. Oh yeah I also shut off and detached to the propane tank. I got a little bit of a sunburn from having to go in and take that tank off. I called it off first with the water spray, the tank not the magnesium barbecue

Coming back from lunch 4 hours later I saw a pool of burning liquid calcium surrounded by a mote of lead oxide sand and blast slag still happily burning apparently this happens from time to time but there's nothing to be done but let it burn it's self out.

Sometimes, and if it's underdeveloped countries most of the times, the firefighter was not informed about the type of materials in burning buildings. All they informed about is that a building is on fire. There was also a case where the firefighter knows what type of fire it is and try to be careful, but the uninformed masses forced them to use water, this happens on EV car fire though, not building.

Magnesium fire can be put out with regular salt. There are even fire extinguishers that contain salt.

Aaah so the transition from burning metal to weirdly low surface tension to fluffy stuff may be peroxides? I have observed this with leaded solder as well. I could test this sometime.

The water experiment did indeed put out the magnesium fire, it seems that if your goal is just to put out the metal fire and you don't care about burning anything around the fire then overwhelming it with water or blowing it up might just work.
