"fired" pun intended?

hahahaahah

Vintage 2000's aesthetic. Totally worth a promotion.

Whoever recommended ice as an extinguisher for a lithium ion fire should be fired - with real fire. Might've well use kerosene from the fuel tanks!

I think they are talking about lithium ion batteries in this. These are types of batteries catch on fire because the lithium ion degrades with heat which causes an exothermic reaction which causes the petroleum jelly electrolyte to explode and catch fire.

Why is water the best way to punit out when water can be the cause of the run away?

What about fires in the cargo hold? Or is there no oxygen in the cargo hold? If that's the case, Do they put pets in a separate oxygenated compartment?

As could be proved by the repeated flares as the shorted batteries had thermal runaways anyway.

Pressurized passenger aircraft, no way to jettison anything, save for some aircraft, fuel. Still, leave it on the deck for long enough, it'll burn its way through and explosively jettison itself...

@@spvillano -- If it got hot enough, it could burn through to the baggage compartment. The baggage compartment is also pressurized. After burning through a thick layer of baggage, then it might have a chance to burn through the bottom of the aircraft and cause it to lose pressure. It would not be a explosive decompression though. A bigger concern would be what else it might catch on fire as it made its way through the baggage or any electric or hydraulic lines it might hit along the way. A quick search says that the temperatures of a battery fire can read 1110F which is below the melting point of aluminum (1221F), so it would be difficult for it to burn through the aluminum on an aircraft. It would be possible to design a way of jettisoning something up to suitcase size on an aircraft even if there was a big pressure difference between the cabin and the surrounding air. There's not that big of a difference in air pressure though. Surface air pressure is around 14.7 psi. Air pressure at 8000 ft is 10.7 psi and that is pretty much the least pressure that you will see in most aircraft. Air pressure at 30K ft is 3.27 psi and at 40K ft is 2.72 psi. So, we're looking at around 8 psi difference between the cabin air pressure and the air surrounding the aircraft. Not a particularly high pressure difference to have to accommodate. A large rotating cylinder with a side opening that could only be exposed to either the cabin or the exterior of the aircraft as long as it had pressure seals along the edges as it rotated. A solution similar to how torpedoes are launched from subs could also be designed (albeit on a smaller scale). So, it would be *possible* to design a way to do such a thing if they really wanted, but if laptop batteries were so likely to catch on fire as to need this, I think their solution would be to just ban laptops from aircraft instead.

nemthefearless shame soda syphons aren't onboard anymore.

@@CaptainK007 but did you know those water extinguishers are almost selzter water as they are pressurized with co2 and have anti freeze in them?

Can't really speak to that, just noting that carbonation acidifies water.

@@definesigint2823 what I can say I am not a chemist but it seems if you look at the ingridients in coke the acid is almost a fire suppressant!

I think to answer your question I have only seen an avertisment for it but I think there is a brief case to suppress this type of fire

Neat idea!

You only need to be concerned if your crotch is the source of intense heat causing a thermal runaway.

Most of the laptops that I've had over the years got too warm to put in your lap even without an overheating lithium battery. That's one of the reasons that the external laptop tray cooling fan units were developed. Part of the problem is that people put the laptops on soft surfaces (laps, mattresses, etc) that block the vent slots on the bottom of the laptops which causes them to overheat. I guess it's a radical concept to the manufacturers that people might actually put laptops in their *laps*...

Well, the video was from *2007*, so it wouldn't be surprised if they looked at bit old to you...

@@jakeblanton6853 i understand but 2007 every computer that came to our shop was alwas LiON even the ones that came out in 2000

@@jakeblanton6853 Laptops made in 2007 look much more modern than those relics in the video.

same

Lithium ion batteries don't contain metallic lithium. Use water for lithium ion batteries, as the video shows.

Read up on batteryuniversity.com, there is no actual metal Lithium in a Lithium ion battery. batteryuniversity.com/learn/article/safety_concerns_with_li_ion

I thought the same thing but I think the batteries in this are lithium ion batteries.

that still wouldnt keep them from exploding.

It depends on which Halon you are thinking of. There are many. Halon 1211 has a toxicity level of 5 (6 being the best, 1 being the worst). See the FAA Airframe & Powerplant Mechanics Handbook - General pages 1-7 and 1-8 (www.faa.gov/regulations_policies/handbooks_manuals/aircraft/media/amt_general_handbook.pdf). Your concern about Halon being toxic is valid, but misdirected at 1211. Also, there are many devices where the battery cannot be (easily) removed.

@@rickgould6554 Ahh thanks for the info!

No, halon isn't very toxic.

yourayneeum it isn't toxic at all.. but everyone would suffocate 😂😂😂

No in fact that is the one advantage of Halon over CO2, the Halon gas does displace O2 to a point merely by existing but this is not actually how they suppress fire they interact chemically to suppress the chemical chain reaction that sustains combustion, namely because the stuff reacts easily with reactive oxygen species like oxygen radicals that are key to sustaining fire. Thus the concentration needed to stop fire is actually incredibly low enough that it could even be used in flood suppression of entire rooms while the people inside could still breathe. If only the stuff wasn't equally effective at eliminating the rather vital reactive oxygen species Ozone in the upper atmosphere and lighter than air to boot so it goes up to the Ozone layer if the stuff is allowed to escape to the atmosphere.

There are many different types of Halon (1301, 1211, 1001, 1011, 101, etc.). Halon 1211 has a toxicity level of 5 (6 being the best, 1 being the worst). See the FAA Airframe & Powerplant Mechanics Handbook - General pages 1-7 and 1-8 (www.faa.gov/regulations_policies/handbooks_manuals/aircraft/media/amt_general_handbook.pdf). You concern about Halon being toxic is valid, but misdirected at 1211.

So is halon when exposed to fire, generates HF gas, which is ever so wonderful for your lungs, bones and nervous system.

... Run away from the thermal event, i.e. thermal runaway. 😁
