Gag Halfrunt Posted August 19, 2016 Share Posted August 19, 2016 Was browsing ebay looking at kegging stuff etc including beer gas and came across someone flogging what looked like a fire extinguisher as a bottle of beer gas. Which lead me to thinking...apart from the container,whats the difference between co2 in a fire extinguisher and a beer gas cylinder? Link to comment Share on other sites More sharing options...
Otto Von Blotto Posted August 19, 2016 Share Posted August 19, 2016 One is rated food grade and the other isn't, is about the only difference. Link to comment Share on other sites More sharing options...

[/quote'] I saw the same one and had to laugh. I'm really not sure if it could/should be used, but I'm thinking there's a different processing method for food grade and industrial. The photo made the whole deal look a bit dodgy. Link to comment Share on other sites More sharing options...
Gag Halfrunt Posted August 19, 2016 Author Share Posted August 19, 2016 Yeah, I sometimes wonder about this "food grade" business. Surely co2 is the same gas however its contained unless fire extinguisher gas is mixed with something else. Link to comment Share on other sites More sharing options...
Gag Halfrunt Posted August 19, 2016 Author Share Posted August 19, 2016 Is anyone willing to gas up their beer with this and conduct the experiment? I would if I had a kegging setup, risking wasting a keg of beer but you will never die wondering. Link to comment Share on other sites More sharing options...
Otto Von Blotto Posted August 19, 2016 Share Posted August 19, 2016 There are a few cats who use fire extinguishers as CO2 cylinders for beer. As I understand it, the food grade gas has been purified more than the industrial grade. It's a moot point for me anyway, I have a CO2 cylinder from a brew shop not far from me so it's easy enough to go and swap when needed, about once a year or so.

[/quote'] Yeah, might not take the risk when I keg. Dont see the point of pinching fire extinguishers or even worse buying them on ebay when a cylinder of real beer gas lasts about a year. Just thought Id ask. Link to comment Share on other sites More sharing options...
Burton Snatch Posted August 20, 2016 Share Posted August 20, 2016 Well, well ,well.....three holes in the ground. It would appear there are some risks you could be taking by using the industrial CO2. The following from a Google search; "The slight difference between industrial-grade CO2 and food-grade CO2 is the type of tests that are done to qualify CO2 as beverage or beer gas-grade compared to industrial-grade. Currently, the FDA's requirement for food-grade CO2 a 99.90% purity rating. The other .09% is made up of impurities such as hydrocarbons or nitrogen. Industrial grade CO2 is 99% pure CO2, also containing impurities such as hydrocarbons or nitrogen. One impurity that all homebrewers should be aware of is benzene. Benzene is a no-no for homebrewers. If the CO2 that you are purchasing has high benzene levels, it will leave you and fellow drinkers with terrible headaches. When I say high levels, we are not talking about much. Benzene is usually an impurity that is referred to in PPB. The benzene level should be around 20 PPB." Benzene = carcinogen. Still though, we are surrounded by cars, trucks, etc spewing out bad stuff 24/7 whch we breath in regardless, so...... Link to comment Share on other sites More sharing options...
