Are there different "grades" of CO2? I work in an industrial setting where we have our own fire protection systems. We have the capability to refill the portable CO2 fire extinguisher bottles. The label just states CO2. The fittings work. It's free... (well, probably would cost me a 6 pack or 2) It's not an hour drive one way....
Is there a difference between industrial or fire fighting CO2 and the food industry CO2?
