So what we have is a warning about a hazard that doesn't exist in normal use, based on information from an internet article whose URL includes "doomed globe" written by somebody who is likely a nut?
Isn't the internet a place to get some wonderful information to pass around to anyone would needs another worry? ?

If I ever hear of a planted tank fan being struck down by his CO2, then I might worry. But NOT if the info comes from the internet!

It's Dihydrogen Monoxide. Monoxide makes it sound deadlier.

There is a real caution that should be made aware but not alarming. Especially if you keep your house closed up in winter and summer. It concerns the pilot light in the water heater. If there's a high enough co2 gas leak and if the co2 has nowhere to vent to the outside it will pool in your basement. With enough co2 in your basement the pilot light can be snuffed out creating a gas leak. So, If you smell something bad and you've been tinkering with the co2 tank, don't blame the dog, go check the waterheater pilot light. And if you smell something bad at night don't flip on any light switches.

I once vented a nearly empty co2 tank in my living room and did snuff out the pilot light.

Thank you!
I don't buy into the "sky is falling" type of nonsense being posted here. CO2 poisoning is only going to happen in an absolutely sealed environment, a perfect example is a space ship capsule (Apollo 13).

The MSDS's are written with BULK storage in mind. Your tiny portable tank is a pipsqueak in comparison to industrial scale vessels. Below is from work: it's 350 gallons of liquid argon, something to be respectful of. A little 10lb CO2 bottle certainly has a lot of destructive / hazardous potential but let's keep that in perspective.

Here is a video demonstrating how some industries use CO2 as a fire suppressant system.

http://www.youtube.com/watch?v=q303E9mLujQ

Note the amount of gas that is being released, and also the fact that the camera man just remains in the room for the entire video duration. No problem.

Is it being anti-social and not obeying commands? Those are classic symptoms of co2 toxicity. Oh no wait.. those are symptoms of a cat.

hey, guys, I never said co2 is toxic gas, and never treat it like toxic gas...
so don't expect me to put on my gas mask or thinking that I wanted you to put on your gas mask, when playing with co2 equipment.

build some good number systems, and play with co2 tank all the time, never worry co2 would hurt me because co2 is not toxic gas.

The safety concern of CO2 is its concentration in air.
no matter how much and how you use it, if you stay in the environment where the co2 concentration is less than the point that cause trouble, it should be fine.

I don't know anything about the site contains any "doomed globe", but the page about the co2 concentration safety make no much difference if you google "co2 concentration safety", other websites will pop up and you will see pretty much the same description about co2 concentration safety, some are hard to read because too technical.

This is another example of alarming news from people who lack training/understanding of the equipment.
If the pilot light goes out for any reason, the thermocouple cools and the gas supply is cut off. Your house does NOT blow up but you will find a cold shower.

This is profound, time-honored advice for any number of situations.

The DOOMED GLOBE is the start of the URL you posted. If you did not question WHERE you read the information you posted, how can you possibly have given it any critical thought before passing it on as truth?

If you don't question what you are reading on the internet, there may really be a danger of you hurting yourself with CO2! Shissh! Are you still expecting to get that money from Nigeria?

so forget about that page from doomed globe, google the "co2 concentration safety" and pick the links other than "doomed globe", and read.

Nigeria scam is fun, I used to respond to those emails back in 2005, just tried to make them work harder to get me on hook, then block or report their emails.
put aside the Nigeria scam, I am not really sure the link that I provided has anything directly relate to Nigeria scam or any misleading instruction on how to properly handle co2, it is about the co2 concentration safety anyway. And I don't think I will be in a danger of hurting myself with co2.
