Where is the refrigerator? Seriously. I keep a refrigerator on my enclosed back porch, and at this time of the year I have to be sure that anything I keep in it can stand being frozen, because when the temperature goes far below freezing as it often does, then the contents of my fridge are going to freeze regardless of the nominal temperature setting I use.
On the other hand, when I started in construction I was amazed to find that contractors often used modified refrigerators to store opened containers of flux-coated weld rod, which has to be kept heated to avoid attracting atmospheric moisture. They essentially used the refrigerators as cheap, stand-up ovens.
