I gave advice?
You said that "natural drafts that exist in houses" is enough to move it around safely and then go on about how dangerous the stuff is?
If your flower room isn't a damn wind tunnel you are failing at indoor.
Sounds like you are the one trying to kill someone, or just confuse the hell out of people by trying to be right.
"any new restaurant Co2 hookup in America is outdoors" - and every bar in america has rooms full of canisters and compressors running full blast 24/7-360, whats you're point? I don't really have one myself just saying.
Oh I forgot you worked for a welder. At least they tried to pound some safety into you.
Have fun with you're "correctitude" Mr. welding supply company.
Nah, I've filled hundreds of cylinders bro. It is heavier and moves slower than you think. Any new restaurant Co2 hookup in America is outdoors for that very reason partner! It is a low pressure/slow moving gas. You don't need to seal anything...it is dangerous to do so! People have died in those little Co2 closets with the door open becuase of leaks. You can die standing next to an open cylinder outdoors if the weather is right!
Not sure where you live or what size room you're talking about, but in America that sh!t is plentiful and to try and save every little Co2 molecule for the ladies is quite ignorant in my opinion. Better to be safe than sorry.
Whether you know it or not, you're giving bad/dangerous advice.
