How not to put out a magnesium fire

[PaladinswordSaurfang]

magnesium fires are easy to put out, i took some magnesium strips home from chemistry coz we were doing a redox reaction prac... after the strip is burnt, it will go out just by waving it fast...

[FirekidE62]

Why would you spend money on something that can kill you and do nothing else when in this form? (No one better say stuff about guns and cars)

[pyronerd628]

they r making their grandma do this, this is a sad vid and they should be arrested for grandma abuse

[FirekidE62]

@pyronerd628 Amen

[aramhampson]

what if you through burning mag in to a pond? Is it splitting the hydrogen and oxygen?

[lxshomeproductions]

@MrBioluminescence i dont know but you should definely try it record it, put it on youtube then pm me the link to it.

[jimpeel]

Portland cement is effective in extinguishing magnesium fires.

Teacher: "NEVER try to put a Magnesium fire out with water!."

Student: "What do u use then?"

Teacher: *no reply*

[tracemaster100]

i like your accent.what accent is that?

[Mizzles240]

LOL at ACHMED

Im getting such good pictures

ITS SNOWING

you can put a magnesium fire out with water if you deprive it of oxygen, it can be done and has been done by fire service experimentation

[Ranavage]

@jamieft2 wrong, burning magnesium reduces the H2O (water) and oxides while H remains, beeing set on fire by the reactions temperature. So in fact, water feeds the reaction by delivering oxygen.

[jamieft2]

@Ranavage it can and has been done, the fire service tested it back in the eighty's, using 8 high powered hoses and large blocks of magnesium, the magnesium forms a layer of magnesium oxide on the outside, I think it takes a stupid amount of water but it definitely can be done

[Ranavage]

@jamieft2 by all respect, just like things dont fall up, how hard you ever try them to do, magnesium burns under water. completley covered with solid water, 100 feet deep or further, doesnt matter. its chemistry and its proven, you cannot extinguish magnesium with water. (check your chemistry book, wikipedia ask a local firefighter or whatsoever) the only thing you might achieve is: wettening the surroundings, peventing the fire from spreading and maybe "covering" the reaction until it stops.

[jamieft2]

@Ranavage i don't know if you have access to any magnesium or not, but if you do take a strip/block ignite it the completely submerge it in water, you will extinguish the flame and the reaction of H2O -> H2 + O will no longer occur, this is because the activation energy of the reaction H2O -> H2 + O is very high, the water cools the reaction down meaning the energy within the reaction is not sufficient to break the strong bonds in a molecule of H2O

[Ranavage]

@jamieft2 i aggree, though depriveing it of oxygen as you stated at first is correct (sand etc., but cannot be done with water) Firefighters usually beginn extinguishing the chassis of a birning car, cooling it down as far as possible, also on the hood before opening it and attempt to cool / extinguish the magnesium engine parts. this works because there is no direct contact. small amounts like you suggested also work when tossed into water, larger blocks though save to much heat

[jamieft2]

@Ranavage not submerged in water it wouldn't, its just simple specific heat capacity Q=MC(delta)T and that works for large blocks of magnesium with say 10 high pressure hoses

[Ranavage]

@jamieft2 to your experiment in the 80s.. of course the magnesium blocks form magnesium hydroxide on the outside, they would do nearly the same without water (magnesium oxide as result due to lack of H in reaction) . water speeds the process up, which is senceless though since it leads to a massive hydrogen flare or even explosion.

[11EatMe11]

the guy who said nothing is impossible obviously didnt watch this video

[DeathIsSly]

I swear on my life this happened. We were burning magnesium in class, in grade 7, year 8. My freind finds some powder on the cart. He takes it and lights it. Just as i thought is was out, i chucked it in the bin, where the rest of it, around 5teaspoons of it, ignites in the bin, masive cloud of smoke, my eyes killing me, my teacher takes out her bottle, and pours it over the fire...... I got in no trouble?

[viperz888]

fake

[mr0loki0jr]

NICE BUT IF YOU BUT 1 KG OF MAGNESIUM POWDER ON IN THE RAIN WHAT WILL HAPPEN??

[grizzlybear019]

@mr0loki0jr well, if that 1kg is on fire then, get far far away from it

[mr0loki0jr]

@grizzlybear019 haha lolz but wil it bur harder ? or willl it exsplode?

[grizzlybear019]

@mr0loki0jr lolz xD yea man it will just be absolute chaos within a 15 foot radius, it'll probably die down soon enough though

[mr0loki0jr]

@grizzlybear019 okay i if i have a magnesium stick I will need a friend too light it?in the rain

[grizzlybear019]

@mr0loki0jr your best bet is to NOT light it in the rain, light it where its not raining and then throw it in the rain or something (not near people or objects OR buildings!)

[mr0loki0jr]

@mr0loki0jr i make my own magnesium and its simple as hell and i use it whit care ofcourse

[GNARNIANS]

i'm getting such gud piktoors.

[abhinayan27]

wats the reaction wid water??

[Berowra290997]

@abhinayan27 It creates Hydrogen gas and that's why it burns.

[Thoralmir]

True story: there was once a group of firemen in Massachusetts that turned a hose on a bathtub of burning magnesium, despite the guy who (accidently) set it shouting at them not to. They told him to shut up and let the "professionals" handle it right before they turned on the hoses. By the end of the night they had to call in about five additional fire engines to contain the dozens of additional fires the explosion caused.

[sergeantdiessel]

@Thoralmir  its funny becuase the military used magnesuim for several combat vehicle in the vietnam war

[americanalah]

Pip Pip! Cherio! Crumpets and Tea!

[JSnyder49428]

so how DO you put out a magnesium fire?

[necevans]

@JSnyder49428 You put dry sand on it.

[Permanganicum]

@necevans But magnesium will react with SiO2 in sand, doesn't it?

[FirekidE62]

@necevans I'm a fire fighter and you just let it burn

[MultiPaulinator]

@FirekidE62 What if you covered it in 20 pounds of soil and let burn off the reduced concentration of silicates, then would it run out of useable oxygen ions?

[FirekidE62]

@MultiPaulinator Yes when the fire is this small but once where I live a paint warehouse full of it caught on fire and when it is just that big you just let it burn out and protect nearby structures and call dominoes cuss ur gonna be there a while LOL!!!

[story762]

@necevans dry sand has silicon oxides

you'd be better off using a dense organic material

[R5H4D0W]

@JSnyder49428 Dry sand, or a type D extinguisher, which uses lithium alloys in the form of powder to "heatsink" the heat away. Other than dry sand, one could use magnesium foundry flux if available

[zjndet1]

I was kind of hoping his suit would of caught fire but " oh well " life is full of tiny disappointments I guess

[georgelopezlover1]

lol what cracked me up is "niiiiiiicccccccceeeeee"

[vwGhost37231]

freakin bri-ish

[brokeanddrive]

I wonder how many cameras were watching.

[BonnevilleNut]

@monsterman655 Thats not true. I worked at Meridian Magnesium. The #1 producer of Magnesium Parts. We had fires daily. U can put out a fire and mag be left over. Haha. and u can also put a mag fire out with water. It just takes a little longer because u have to bring the core temp of the fire down to keep it from spreading. The down draft tables are filled with water for a reason. So u can push the fire into the water and put it out. I am very familiar with this stuff.

[cowgoesmoo2]

Stick it in your mouth like you would with a match.

[elite549]

what happens if you put magnesium in an ocean??

armageddon?

[tesmo2]

@elite549 there wouldnt be enough magnesuim to do that with the ocean......hmm but its salt water..so i'm not to sure...if you tryed with the salt water in a tank or bowl maybe you would find out...

[charmio]

@monsterman655 That's what he is demonstrating you Dumbass, also, maybe you should research your thoughts on inextinguishable, Mg can be with extinguished (depending on conditions) with Novec 1230.

[kakindebroek]

with woater!...

Wtf dude

[DragonFlyback256]

@kakindebroek

That's British accent. =D

[cbsctomh]

Do the British Firemen wear business suits to a fire?

[seasonedcurlies]

@cbsctomh Yes, and they put out fires with watering cans

[bee123UYA]

@seasonedcurlies hahahhahaha

[aloisbembel]

@seasonedcurlies

And they always exercise their typical restraint

[seasonedcurlies]

@aloisbembel Exactly, it's in the British Fireman's Handbook. It also says that they have to aggravate the fire before they put attempt extinguish it

"I'm getting such good pictures!!"

[Keemyarcanemissles]

@seasonedcurlies lol

[Legofan78]

@cbsctomh I think that's a scientist

[jamies41]

@cbsctomh yea of corse

[jackiechan511]

Couldn't they throw that fire-laden magnesium in the river or lake. Lots of water there

[execk2]

The last question was, "what do you do then?" Then it stops........

[chris11sholtz]

@execk2 you die, mister bond.

[willaitken]

i can hear rado

[kcnkickthecat]

You may as well be pouring N2O onto it... :D
