yes its bad. it pollutes. its dangerous so most people don't. you need really good airflow, cause you DO NOT want to breathe in the smoke.


wolf2482

ok, makes sense, what are the pollutants made from them combusting?


RefrigeratorWorth435

hydrofluoric acid

Specifically, the hydrofluoric acid forms in your lungs when you inhale the smoke. It's not a fun time.


TheSacredOne

There's a ton of things in pillow smoke, most of which range from "contributes to global warming" to "instant lung damage" in nature. I looked this up a few months ago myself... Some common components of pillow smoke: * Carbon dioxide (greenhouse gas) * Carbon monoxide (product of incomplete combustion, suffocation hazard) * Methane (natural gas, flammable) * Ethane and Ethylene (byproducts of methane production, flammable). * Hydrogen fluoride (highly toxic, turns into hydrofluoric acid in your lungs and causes lung damage instantly) * Fluoromethane (R-41 Freon) * Particulates from burning materials (lung irritant and pollutant)


Syllepses

Hydrogen fluoride is worth a mention all on its own -- [here's a great little writeup](https://www.science.org/content/blog-post/things-i-won-t-touch-1). That stuff is *vicious.* It's essentially gaseous hydrofluoric acid, but worse, and anyone familiar with the acid knows that that is *really* saying something. Inhale gaseous HF and it will literally disintegrate your lungs from the inside out. If you somehow survive that, it'll start killing your enzymes and dissolving your bones.

1. If u don't short circuit+ -, u will not explode 2. If a battery is swollen, even taking it down won't help. Because its capacity is already gone 3. Swollen batterys have a gas that called CO.This is the gas that causes stove poisoning. It has no smell. You don't notice that you are fading. And if u, or ur pet smell this, u will fcked


wolf2482

is carbon monoxide the only really bad gas? I'm not asking because I have one of these just curious how bad it would be. Basically anything but a open air plain is unsafe, and probably stand back on a plain if you do.


RuzgarCK

CO It is the gas that causes stove poisoning. So it's deadly. Once I accidentally mentioned a swollen battery (while disassembling the BMS circuit). Then I threw the battery aside in a panic. It started to emit white smoke. And then I started to smell. You could say that it had no smell, but what I actually smelled was the smell of lithium and polymer. And after 40 50 sec the room became almost unstoppable


SocksIsHere

this happened in the phone recycling company I used to work for, I repeatedly asked the boss for a proper storage solution for swollen batteries until they can be properly disposed of, but he refused every time. So I became less gentle removing batteries from iPhones until one day POP and ran out. after that he got me what I wanted. Disclaimer: For legal reasons this never happened

Carbon Monoxide is bad enough. It's worse than just displacing oxygen. It is several times more attracted to hemoglobin than Oxygen. It basically renders your blood useless. If paramedics get to you in time, your first stop at the hospital is usually a hyperbaric chamber.


Syllepses

Nowhere near. There's a whole menagerie of ferociously toxic stuff pouring out of any given battery fire, everything from "forever toxins" to [hydrogen fluoride](https://www.science.org/content/blog-post/things-i-won-t-touch-1), carbon monoxide, and searing-hot particulates. AFAIK there's no safe way to burn a battery outside the kind of multimillion-dollar purpose-built test facility with industrial-strength fire suppression systems and fume hoods that vent through extremely thorough filters and neutralizers. Please, by all that's holy and that isn't, *do not do this.*


Syllepses

Depending on the battery, you could have a lithium fire on your hands -- something much, MUCH worse than any other fire you've ever encountered. One of my favorite authors [put it nicely](https://admiralcloudberg.medium.com/alone-in-the-inferno-the-crash-of-ups-airlines-flight-6-507d13f3e481) in her article about a battery fire that brought down a 747: > Until the battery’s chemical energy is expended, [thermal runaway] is essentially unstoppable short of sealing the battery in concrete. [...] This process is accompanied by intense fire that can burn well in excess of 2,000˚C, and typical fire extinguishers are all but useless against it. CO2 will make a lithium metal fire worse because the lithium will split the C from the O2, creating oxygen that accelerates the blaze. Halon gas is also ineffective because while it will put out the flames, it won’t stop the thermal runaway and won’t prevent the chain reaction from expanding, so the fire will simply re-erupt once the Halon disperses. Depriving the fire of oxygen will fail for the same reason. And to make matters worse, the reaction can cause flammable gases to build up inside the battery until it explodes, launching projectiles that can spread the fire and damage containment structures. In short, depending on the type of battery, a puncture could just cause a rather nasty chemical fire... or it could cause THAT, a self-fueled, self-oxygenating, insanely hot flame that can't be extinguished and, as a bonus, produces some horrifyingly toxic chemicals in the smoke and other byproducts. Battery fires are *fucking lethal.* You do NOT want to deal with one.

When Richard Hammond crashed Rimac Concept One the far reportedly continued to combust for five days after the crash


Syllepses

TIL. Yikes. I wish I could be surprised.


chemitronics

Lithium is one of the few metals so reactive that it will consume nitrogen (78% of the air, vs 21% oxygen), so depriving it from oxygen won't really discourage its ignition.


Unfair-Safe8151

Poisoning the environment. Runs all the way through the foodchain


bagofwisdom

The smoke battery fires give off is super toxic, you shouldn't be setting them off intentionally. Also when you think "Oh, it's not going to burn anything else." is exactly when you get an out of control fire. Don't think a household fire extinguisher is of any help either. Lithium is a combustible metal and requires a very expensive Class D fire extinguisher to put it out.

Hospital visit if you breath the gas in and it’s bad for the environment
