I had thought about this a bit with a future pole barn workshop that I have in mind when I can do it. However, this is also applicable to a propane generator shed with my house. Initially it seemed like it would be best in these scenarios to have them housed on the outside of the main building (workshop for oxy-acetylene, house for propane). However, my wife expressed a concern with storing the propane in a small shed where it isn’t temperature / humidity controlled and made me wonder if that is true or not.
I know in the case of the propane, that my tanks are small enough to be up against the wall of my house, just x feet away from doors / windows, according to recommendations. However, is it better from a safety standpoint to do that with that or any other flammable gas tank? Is there significant increased corrosion (still being sheltered in a shed)? Can 100+ degree heat outside, and probably higher in an enclosed shed, be a concern (or wide temperature swings)? What about minimizing any damage to the main building in case of fire, or worse, explosion? Is there any way to create a firewall or “direct” any potential explosion away from the building, like with a thick metal plate? Or would that just turn into a projectile?
I guess I’d like to see what others have done for their home or businesses in this regard and / or others’ thoughts on this. On the surface it seems like having them stored outside the main building (with hookups and valves inside the main building for the workshop) would be safer and more convenient for gas delivery swap-outs (with a lock only they can get into), but is it?
