Personally, after seeing inside industrial facilities I’d personally prefer to use something they’re forced to classify differently. Yes, I know there’s a level of acceptable puss in milk or bugs in food, but I’d rather play pretends that the person processing everything is also concerned that I might be ingesting whatever is in the canister. Some people don’t like using tap water on their pasta and we humor them because it’s going to get boiled anyway but it’s their own personal use.
It really depends on the production process,
Imagine of the production process intrinsically produces 3% carbon monoxide,
that would be very bad for inhaling !
But as industrial inputs that can be perfectly OK, as long as it is known, expected and dealt with.
But over time, gas manufacturer devised ways to make pure gas for the lowest price as any other production process.
So that’s the only gas that is available already, and has been for a long time.
That’s why I’m not worried about CO2 gas for the welding shop.
The most likely contaminant is going to be a few milligrams of regular air
But yes in the abstract, you can’t use anything but certified food safe gas.
The problem is that now your distributor needs to have food safe practices along the whole supply chain.
That means not the welding shop, because they’re not a laboratory or kitchen, they don’t have a food safe protocol for gas handling.
And the industrial distributor will not sell you any gas if you buy less than a couple tons.
So, in this case buying a sodastream cylinder retail is probably going to be your only option.

And that means paying 18$USD for 380 grams of CO2
Instead of paying 20$USD for 2270 grams
