Propane storage

[Pntyrmvr]

The mercaptan used to scent propane has a long shelf life.

Even residual propane from coupling and decoupling appliances can leave some behind. The heat in the box only makes it worse.

That said my Mom had a tank vent its excess pressure once while it sat in a sunny, hot backyard.

Test the valve with a soapy water solution and look for bubbles. Pour the solution directly into the valve opening with the tank on its side. They can leak from three places. At the threads of the unit, the valve shaft, and of course the output zone.

That said, life is short. Buy a new cylinder.

Which a whole other question, since the local propane company is no longer open to the public.

I had a similar situation years back. I agree to replace the tank if that is where it's coming from but in my case it was the hose used to connect my tank to my BBQ and stove which I kept in my storage box with my BBQ and tank. That hose held a bit pressure that would slowly leak producing the smell. Be safe.

Good point. I'll check the tank and start bleeding the hose better.

Close the valve at the cylinder and leave the appliance to burn off the residual propane in the connector hose.

I found the rubber hose will still smell even if burned off (pressure gone). These days I usually connect the hose to itself which seals it off and protects the hose ends.
