Helium test is for the highly toxic gas service equipment, this standard of leak test is to prevent leak, normally down to molecule level. co2 is not highly toxic gas, and I can't measure how many co2 molecule escape from the system.

the safety issue here is the co2 concentration in enclosed environment. the proper operating procedure is pretty much the same as any welding shops, properly handle high pressure equipment, prevent frostbit and "keep the windows open", so co2 concentration can not reach to the level that cause trouble.
