Get it off the floor, off of standard shelving and pallet rack, and put it somewhere you don’t have to fight with it each time you need some. If you’re really smart, you’ll put it where overhead lift equipment can get to it – because once you get it stored right, you’ll wonder what the heck you were thinking earlier.
