The CO2 you're using is not safe...

[fuhmon]

your worried about contaminants in co2? how about you sitting in rush hour traffic huffing vehicle exhaust? or the trace amounts of metals exhausting out of your computer right now? there's more important things like filling your fermenters... troll much?

 

[beaksnbeer]

Most welding requires a "pure" gas to begin with. "FOOD GRADE" ss welding is a tight nasty bitch I have been their OP is NUTS

 

[diverpat]

This "problem" comes up every year or two, but the people who point out the problem never seem to have any backup data.

The same thing comes up in the diving realm also regarding pure oxygen for decompression gases. At most facilities, the medical and weldeing oxygen comes from the same liquid source. The difference comes in how the tanks are treated. Medicals tanks are supposed to be drained and vacuumed of all residual gases to avoid contamination, this is the stuff many divers use. Industrial O2 tanks don't get scrutinized as much. No one wants to suck down acetylene tainted oxygen when your stuck under water. I'd assume the same rules may apply to food grade gases but I'm not sure.

Fixed

Example, our co2 is delivered as food grade. We sell it to our welders as well as our restaurants.

Wow, y'all's Welders serve beverages?

Bold words sir! Speak for yourself!!

In the title of this thread, it should read "you're" not "your". Your is a possessive adjective, you're is short for you are - never trust anyone whose grammar skills aren't up to par; especially when 'their' talking about CO2 safety and beer ;-)

Technically, in the title, the "o" in Co2 should be capitalized as well, to read "CO2".

 

[DieterVonBrauhaus]

First, I don't mean to be freaking anyone out or causing panic.
Just letting you know that if you are brewing and kegging a LOT of beer you should invest the money in food grade Co2.

Its my understanding that trace amounts of oils get into the Co2. I worked at a gas distribution center for 2 years.

Come on...someone delete this thread. Mostly all Co2 is food grade nowdays.
This is redunkuloius, it's like saying the food grade plastic tubing that we use to keg will cause us to have cancer because it's made out of oils......

What?!? you don't want people to know that the Co2 their using is NOT SAFE? Come on, man. its NOT SAFE.

 

[subliminalurge]

Sheesh.

I drink beer by the gallon, whiskey by the bottle, smoke 2 packs a day, dive straight for the fat on any piece of meat I eat, and I shave my head every summer and spend most of my free time outdoors. And it's been 30 years since I used sunscreen.

I drive too fast. I skydive. I don't get enough sleep, and I'm pretty much always overstressed. I just had the birthday where I'm supposed to have a prostate exam, and I haven't done that. In fact, I haven't been to a doctor in over 5 years.

Hell, pretty much everything I do all day long, every day is "bad for me".

But it's the CO2 that's going to finish me off?

(I flagrantly ignore the warning sticker and don't wear safety glasses when I use my hammer, too....)

 

[bigbeergeek]

Good luck with all that...

 

[subliminalurge]

Good luck with all that...

Been working out fine so far. Everything a person can possibly do is "bad for you" if you ask the right person.

Life's too short. And it seems that the only way to make it a little bit longer is to give up anything and everything that makes being alive enjoyable in the first place.

I'd rather live 70 great years than 95 miserable ones.

Sunscreen ain't that bad to put on...

And cigarettes are pointless.

 

[subliminalurge]

Agreed on both points. Still will probably not be messing with sunscreen any time soon, although the smoking thing is probably going to come to an end soon (more because of the ridiculous expense than for health concerns, though....).

Still, I find myself fairly unconcerned, in the grand scheme of things, about my "CO2 consumption", regardless of where I got my tank filled.

 

[Pascal]

Is this why my beer gives me gas?! Well s**t.

 

[subliminalurge]

I always thought that was the comparatively large amounts of live yeast....

 

[Pascal]

...but what if my over carbonation combined with the toxic gas is slowly dissolving my insides?

Na, I think I'm ok.

You haven't said much since others have raised points against your post. Do you have anything to contribute / defend your argument?

I didnt come here to argue with anyone..
Just passing on the information I learned working in the industry.
Might be right, might be wrong. Better safe than sorry is how I look at it.

If you think it's false just ignore then..

 

[sudsmcgee]

Sunscreen ain't that bad to put on...

Actually, sunscreen has never been proven to prevent skin cancer (or any other cancer for that matter), but the vitamin D that it inhibits CAN prevent many forms of cancer. Many scientists now say that sunscreen might actually increase skin cancer rates (melanoma in particular since it has a strong tie to vitamin D levels).

But, back topic of how bad a few grams of CO2 is for me.....

But wouldn't this be more of a debate than an argument? If it is a legitimate concern, there should be some scientific literature on the matter with information for both the pros and cons of CO2 that is or isn't manufactured at food grade standards.

 

[IrregularPulse]

I dont have any studies on the specific chemicals.

I worked at a natural gas distribution center for 2 years that also distributed other gases. They werent able to sell Co2 legally to restaraunts to use it for cooking purposes because they didn't have a FDA approved filtration system for the giant Co2 process. This was 9 years ago.

The best thing to go is to get a large tank and put dry ice into it, heat it slightly, and allow for the sublimation of the dry ice to create Co2.

The ice should theoretically be sanitary, and you can make the inside of the tank sanitray. At the end of the day, the ppm of the oils is probably extremly minute. But its something to worry about if you go throught 30+ kegs a year!

I don't mean to be freaking anyone out or causing panic.

Don't shoot the messenger.
Im not trying to strike fear into everyone here. Im just letting you know what I learned working at a natural gas districution center 9 years ago. Granted technology may have changed since then.

As OP posted, it is probably true that today mostly all Co2 is food grade since its cheaper to not use two different process's to create two different grades of Co2.

What it really comes down to is, it's better to be educated than to spread false information in the name of "safety".

You admittedly don't know what you're talking about despite "working in the field" so you're no more qualified to spread danger rumors than you are to recommend it being safe.

I worked at a gas station in college, doesn't mean I know how oil is processed.

 

[Paulgs3]

Hey! This needs to be researched. I'm filing for a grant.

 

[bmbigda]

since scientific studies are lacking on this subject, it seems the next best thing is data. consider how many Americans own kegoraters. Homebrewers makeup a small percentage of the total at-home CO2 ingesters. We had 6 of them in my fraternity house alone. With that many individual cases, if a risk existed it would have occurred and surfaced.

in other words, when's the last time you read an obituary for death-by-CO2?

 

[corkybstewart]

I guess I'm doomed after 15 years of drinking homebrew carbonated and dispensed with carcinogenic CO2.

 

[bwomp313]

Interesting little known fact. CO2 is one carbon and 2 oxygens

 

[broadbill]

You breathe in air containing oxygen and breathe out air with carbon dioxide....you can't explain that.
