How big is your CO2 Tank?

[microbusbrewery]

A leak on a tank that big could also kill you and every animal in the house in short order.

A 5# tank is no threat.

A 20# tank, maybe, but the conditions would have be just right... a small house or apartment, very well sealed, etc.

Emptying a full one of those tall tanks indoors could quickly drop the oxygen concentration in the house below the level required for human/animal life. It's no joke.

I'd never thought of that before, but that's a pretty good point. And the safety relief valves do fail from time to time. Someone had a post on here a couple weeks ago about how they'd picked up an exchange tank with a bad safety valve. If I remember correctly it was just sitting in their basement when the safety valve blew and vented the entire tank.
