I theory yes,
In practice nobody makes contaminated industrial CO² since the 1950s.
If there are contaminant the gas supply will be VERY upfront about it.
Usually it’s over 99.99% pure, very low moisture
There’s also usually very few commercial sources of industrial gases in any particular town, so it’s usually not difficult to source it.
If you want to pay extra, then find “food grade gas”, it’s probably the exact same gas because the industrial gas is already so pure it meets food grade quality. Probably the only difference is the fitting is kept “food clean”
My gas guy gets it from “air liquide”, it’s a welding shop
And when you look at the product’s safety datasheet
It even already lists it as “food grade”
They even list it as “100%” pure but of course, nothing is 100% pure.
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.
Only thing I’ve been told to be mindful of is that sodastream CO2 cartridges are food safe and a lot of the cheaper alternatives aren’t.

In Germany every supermarket has their own sodastream-compatible cartridges, 100% sealed and food safe. And 30% cheaper or so.
