storage of gas cylinders

[NickD]

Just wondering where people keep their tanks.
I know gas suppliers recommend outdoor storage but I've kept a 3.9 kg propane tank
in my well ventilated space for 20 = years with no probs.
I ask as I want to get a spare as back up but the only one I saw at the local tip was 7kg.
I'm not sure why but this has left me, as I say, wondering...:ta:

I have my 9 kg LPG plus the D oxygen tank next to my soldering bench, they are easy to access to shut them on and off

I do the same as China but ALWAYS turn them off as soon as I finish using them even if I am going to use them again very soon.

Good, thanks for the input.
It isn't really practicable to do anything else really.
