To clarify, my concern is the 10 lb. CO2 tank emptying into the basement due to a hose failure, cat pushing a tap open, etc.
It hasn’t happened in the five years I’ve been kegging, but now I’m wondering if it’s a hazard. I’m worried about my wife walking down there with the baby (the basement is how we access our parking area).
Ahh… What are the chances? Still we wear seatbelts, install smoke detectors, keep fire extinguishers, lock our doors. Go for it if it gives you piece of mind.
Here is one that is a bit cheaper with some good reviews.

Scratch that. Meant for plants. Won’t help a baby unless he or she has a green thumb.
I picked up a plug in model at Home Depot/lowes for around $35 I think. Not all the bells and whistles you’re looking at, but I feel better about brewing and fermenting now, but I also do not currently keg
how many liters of co2 are in a 10 lb tank? a lb of co2 is a little less than 9 cubic feet of gas so a 10 lb tank contains about 90 cubic feet of gas. a 10 x10 x10 room contain 1000 cubic feet of space. that’s not really a significant amount when spread evenly throughout your basement. but I suppose if it all pooled in a low spot 10 X 10 it would make a layer a little less than a foot deep.
I suspect you’ve got a carbon monoxide detector, not carbon dioxide. CO detectors are much cheaper and widely available than CO2 detectors.
CO2 is dangerous stuff when concentrated and if you find yourself in a basement full of it there’s a good chance you won’t be able to get out by the time you realize it (read up on Lake Nyos for the worst-case scenario). That said for my setup of a 5 lb. tank and decent-sized basement I’m not particularly worried if the tank empties. If I had a 20 lb. tank I would be getting a CO2 alarm for sure.
