How to store nitrogen cylinder

[new.solution1]

I want to store indoors, with a cap on it. I read that you should only store outdoors, away from sun too.

Somewhere where it won't fall over because if it does the valve breaks off it becomes a missile rocket.

I have a 9.4 Ltr and a 2 Ltr tank in the spare bedroom. It's cool in the winter months. The summer just gone they were cool enough with the fan on them day and night.

The reason for recommending only outdoors is because of potential leaks that could kill or injure any people in that space. Do you have a garage? Strap it to the wall, or otherwise position it so it won't fall over. If it has one of those metal caps that cover the valve and whole top, keep that on it. Test for leaks with a little soapy water. If leakage, you'll see bubbles. If no leakage, it should be fine in a garage.

I had a 50 pounder of the old style metal tank, and it was heavy af. Just used it a few times to replace O2 in food storage containers. It's going to be under a lot of pressure, so any possible damage to the valve is a risk. (like if it fell over and broke the valve, it becomes a rocket)

Have had a CO2 tank (not nitrogen) blow off the safety valve in my hot vehicle, and you want to avoid that kind of exciting event. Keep it out of the sun, and perhaps not at max capacity. The main risk if keeping indoors is leakage replacing the O2 in your place with nitrogen. You won't notice it before you pass out. Death or serious injury could result, depending on the leak size and the cubic footage of your space.
