Help Avoid bitterants in compressed gas duster?

[JOkE2109]

I have been considering Shallow Water Blackout method recently. From my research, the best and easiest way to make yourself pass out is not hyperventilation, but inhaling an asphyxiant gas. I would be using a can of compressed gas duster containing difluoroethane for this. However, these dusters contain bitterants to discourage "inhalant abuse" which supposedly makes the stuff taste disgusting. I'm not too concerned about it honestly, but it would be nice to know if there is anyway I can avoid having to taste them. All I could really find is this:

Air duster... air duster works with hanging..

Disclaimer: I am not suggesting that anyone do this or try this.

The btterant can be avoided by flipping the can upside down and spraying out the cloudy stuff before inhaling it.

In this post, they were talking about combining an air duster with hanging, which isn't what I would be doing, but I assume it would work for both purposes. I don't really have a way to confirm this information though, as when I try and look this stuff up I can't find anything about avoiding bitterants except random Reddit posts complaining about it in normal use (and not getting any meaningful suggestions either). So, if anyone could chime in, it would be appreciated.

Have you considered obtaining food-grade nitrous oxide? Adding bitterants to N2O for whipped cream seems to be less common.

For what you are looking for exactly is liquid nitrogen. It is an inert gas that fails to activate the body's hypercapnic alarm response system and you pass out within the breath or two without any sense of suffocation or panic.

Because it is so cold that cryogenic temperatures spilling a little in a bathtub or on the floor will create a cloud of vapor that will linger and rise from the bottom up and displace the oxygen, one of its greatest hazards and the cause of a multi-casualty 14 peaceful death Cascade incident at a poultry plant where a worker passed out after a leak and another went into rescue becoming a casualty, then the third going in to rescue both becoming the third casualty, and then bodies piling up on top of each other until the fire squad cold and evacuation and had to go in with scuba equipment.

The costs are they're cheap. All you need is a $150 cryogenic Dewar container and then filling it up with liquid nitrogen at your local welding supply shop, ice cream supply shop for industrial gas supplier at anywhere from $1 to $4 a liter, cheaper than bottled water. You will need PPE, specifically cryogenic gloves for $35 and a face shield.

You could also do it in a vehicle cabin as long as you plug your aft trunk over pressurization vent so when you spill the whole 10 L the vehicle essentially becomes a hyperbaric nitrogen chamber and death becomes instant within 4 minutes as the O2 concentration drops to less than 3% resulting in coma in a minute and death within three.

In another embodiment, you could decant the liquid nitrogen in a very well weatherproofed tent.

Both a tent and vehicle cabin will have a confined space volume of 30 cubic meters or 24 Square cubic feet. 1 L of liquid nitrogen expands to approximately 700 L of nitrogen gas, and so you could only imagine the liquid to gas expansion coefficient would create quite a deadly plume of vapor that would displace all of the oxygen and composite atmospheric air in a confined space that would expel out through any opening exhaust vent as the LN² rapidly evaporates from liquid to gas leaving behind only 99% nitrogenized atmosphere lethal within a few breaths or two.

If not a confined space, the shallow drowning technique would also apply since liquid nitrogen vapor will basically stick to the ground in a low hanging fog comprising pure nitrogen. Multiple casualties and children have died after some full some liquid nitrogen in a pool party and people swimming in the pool or basically killed like flies instantly as they were deprived of oxygen while the liquid nitrogen converted from liquid to gas and swept through the pool, no screams or cries were heard because there was no suffocation just passing out and I'll try this post the link when I can find it.

I'll come back and edit this post with a video and some pictures.
Alternatively, and conveniently you can buy carbon monoxide cylinders or carbon monoxide powder for cheap, instead of having to go through the hassle of generating your own with briquettes and charcoal why not get some off the shelf here are some pictures (vendor details redacted)

Alright, thank you for your responses everyone. Will consider these options.

Ive found this, but it's considerably more expensive. Would it be effective?

Inhalants like difluoroethane and other aerosol propellants will only produce momentary unconsciousness unless you can arrange a constant flow of the gas, either from a hose/mask arrangement or by flooding the space (like @DeadManLiving suggested with nitrogen).

Getting hold of things like liquid nitrogen or compressed carbon monoxide depends heavily on where you're based. In the UK it's quite difficult to get either of these as a private individual. Even nitrous is much harder to come by now since it was regulated as a class C drug in 2023.

That would be a liquid nitrogen Dewar. It is a vacuum insulated container and the only type that can contain LN2 in a liquid cryogenic state for storage. You would need at least 10 Liters, unless you have some other method of shallow drowning yourself in a pool of ultra cold nitrogenated or nitrogen blanketed space. There have been many reports on industrial accidents where the density of nitrogen was sufficient to overcome any exhaled residual CO2 and or presence of oxygen, but you're mean concern would be not getting frostbite. In fact your major concern would be not getting found timely, where you would be rescued only to possibly be in a persistent vegetative state due to the hypoxic injury however the window of probability is very low humans can live without oxygen > 5min but that would be entering coma not death.

You would need a confined space or you would have to let the nitrogen pass through some kind of a heat exchanger or set of tubes to reach room temperature and continuous flow. If you could build some kind of contraption like that then you'd have almost 700,000 L of N2 flowing in a purge across a mouthpiece if you can tie yourself down and strip everything correctly so nothing goes wrong when you lose consciousness and motor function.

As @JOkE2109 mentioned, the liquid nitrogen method has its pros and cons and its hazards. It certainly effective in lethal if you know what you're doing but it is either highly restricted or no pun but a joke to get in the US lassie faire states countries. So if you're in the UK or don't have the funds or resources to set up a shell company, then your best bet would be your local college laboratory. Maybe enroll as a student student and you will certainly have unlimited quantities of LN2, although I'm not sure how controlled it is but it certainly is in many parts of Europe. In the United States it's a joke to get - I'll post a video of how easy it is, for god sakes this family could have died the way they procured it (coming up when I find it).




In India you can get is easy to my knowledge based on a few peer accounts. If you have the resources and will there's always a way, sometimes a harder way sometimes you get lucky and find the easy way.

Death by LN2 nitrogen blanketing in a confined space should have a good quantity source in a well controlled environment. Much more difficult to control liquid nitrogen than N2 gas. But I suppose if you dump it in a hole and inside of a tent in a sufficient quantity like 20 L worth and brace yourself face down as it comes upstream, then is that should be considered a 99.9% lethal rate especially if you plant deterrents to rescue such as modded pressure cookers or a / b particles that are detectable with Griger Countets or warning of lethal booby traps if the perimeter is disturbed.

That would impede rescue by dozens of hours if not days untill they fly in a special HazMat team.

Having multiple methods in concert would minimize the probability of failure and Murphy's Law. But there are diminishing returns to overcomplication.

Is there a recommended surface to into from the dewar, perhaps ceramic?

I am assuming that the top of the dewar can't simply be removed to allow sublimation?

Pyrex glass seems to be recommended but those are usually pretty small volume containers and larger one might be expensive. The cap on the dewar is made of Styrofoam, but I'm not sure where one would find a styrofoam container. The dewar itself is a metal container, so perhaps a sturdy metal bucket?

I'm becoming very interested in this as I live in the US, and the video posted by @DeadManLiving shows that it is quite easy to obtain. The idea of immersion in a hypoxic environment vs having to wear a bag, mask, etc. seems like the way to go. The DIY version of the sarco, essentially.
