Presently, I store mine under the back step, but only until I get my shop/storage building built. And once it is built, any gas or fuel products like it. Will be stored in a vented to the outdoors closet. Plus, I never store gas or fuel of any type, in one of those plastic containers. All I will ever use are the metal ones, yes the can cause a spark if they hit something. But the plastic ones can cause a static spark by just touching or moving them. I cringe, when I see some idiot filling a plastic container with gas, before removing the container from their vehicle. It's not safe to do that, not even on the tailgate of a truck.
