instantaneous death by (exploding) electronic cigarette
« on: May 18, 2018, 12:06:01 am »
I knew that smoking was bad for your health, that is why I don't do it, but I wonder what effects this sort of incident would have with other battery operated devices ???

An exploding electronic cigarette caused the death of a Florida man earlier this month, an autopsy determined.
.............
died on May 5 from parts of an electronic cigarette that penetrated his head, according to the autopsy report.
.............
thermal injuries to about 80 percent of his body, including his chest, shoulder, abdomen, back, arm and hand, according to the autopsy report.
..............
the shape and construction of e-cigarettes can make them act like "flaming rockets" when the battery dies.

But you don't stick phones in your mouth.

.... or is that something that you do?

Death? I heard legs burned so that is 10-15% but 80% of the body and instantaneous death ? Not read that.

Very close to your mouth and head if you are talking to somebody, that is what makes this so scary.

Well not me, but some do:


 :-DD

Later edit:
Oh, wait, Google found an even better example: an exploding phone kept in mouth as a flashlight, to free the hands while searching for a sugar pack (the video does not show the explosion).



Later later edit:
Oh, wait, this one is with an explosion video caught on the surveillance cameras: a dude bite an iPhone battery in the shop, to check if it's real :o
https://www.mirror.co.uk/news/weird-news/iphone-battery-explodes-mans-mouth-11898158

And with that, for the next 6 month or so, Google will probably return me only stupid videos... I forgot that I was logged into Youtube while googling "phone mouth explode".

If I understood it correctly what killed him was part of the ecig ending up in his brain. I suppose some are shaped a bit like a gun/cannon and if the battery suddenly explodes inside a metal pipe, the mouthpiece area might shoot out like a bullet?

It then caused a fire, but I suppose he was dead by then and the reason for the severe burn was that he was already dead and couldn't put out the fire. This got to be really rare though, but they should have this in mind when designing the units I suppose. Phones should really be less dangerous (assuming you keep it out of your mouth) but perhaps they too should be careful not to confine the battery to much.

It's been years since the last major brand phone used a metal case battery.
I've never seen one single non polymer pouch battery for years (except for 18650, of course).

One of the reasons I only buy Samsung high current 18650s for mine.

The last mod I bought came with a free battery. The battery had no part number on it and the only thing printed on it was Danger: Do Not Use With E-Cigs, or some such.

I just changed the (Samsung) battery the other day because it was hardly holding any charge anymore. It had swollen enough to require pliers to remove it. That was a bit scary, not visually noticeable but enough to worry me. I use to do 100% to 20% charging, I am trying to keep in the 80% to 40% range now to baby the battery a little more.

I am genuinely surprised there are not more battery accidents with how dangerous lithium battery chemistry is.

Lithium chemistry isn't dangerous.

Drawing ridiculously high currents for long durations and then rapid charging them so you can get your next nicotine fix on the other hand..

In other words, the top was too weak to contain the pressure and let go first. Definitely like a gun...

Nothing to laugh about if you ever knew someone that died with that disease.

Die with style ... at least here, as I've seen locally here most this suckers used these "suck bomb" just to gain street cred.  :palm:

It had swollen enough to require pliers to remove it.

Maybe this was what happened, the mod vents on the bottom while the battery if installed in the proscribed manner vents on top. So if the battery swells and closes the gas path to the bottom it can build enough pressure to blow through the insulator on top, through the atomizer and launch the mouthpiece, which isn't threaded on.

@kjelt
I apologise if I came across as a prick. It wasn't my intention.
I should have been more sensitive to the issue.

I heard of people doing mods where they put a coil that's like 0.8 ohm.  That's practically dead shorting the cell.  :o  Wonder if stock ecigs are much safer and if it's always modded ones that have issues.

As for phones I think part of the issue is the obsession with making them so thin. Trying to pack that much power into a thin battery is asking for issues imo.  It's probably frustrating being an engineer and constantly being pushed to make these things thinner and thinner beyond what is practical.

0.8 ohm isn't particularly low in the scheme of things, you need heat to turn a liquid into a vapour. On a single fully charged 18650 it will draw about 5A. If you're using a high power cell capable of giving 20-30A then it's well within spec of the cell. I suspect this guy was using a much lower resistance coil. As was mentioned before the problem is that the cells vent at the top and mech mods usually vent at the bottom. In this case a fatal design flaw.

There's really no sound reason to use a mech mod any more. Regulated mods just get better and can supply as much power as any sane person would want. If you want ridiculous amounts of power then rolling your own regulator really isn't too hard. I've designed and built a couple, using one right now controlled by an Atmel 328p I made a couple of years ago powered by a LiPo designed for RC.

If it is completely sealed then pressure wouldn't have to build up particularly fast even. Iirc there is only soft tissue between the mouth cavity and the brain so it probably doesn't take a lot of energy for a projectile to be lethal either.

Just adding a vent hole at the top of the battery compartment as well as the bottom might do the trick though? :-\

This thread has been making me think about doing just that. Mine has the battery compartment parallel to the mouth piece instead of under it, so it would be a simple mod. My worry then would be liquid getting in the hole and shorting out the battery. So I still have to think about it.

Any time you have lots of energy in a container you either have a gun or a bomb. The only question is how easy it is to release the energy in a short amount of time.
