I have a few jugs of powder stored in a spare bedroom closet,and I sometimes worry that if I ever had a fire my insurance wouldn't pay .I would like to move it to the garage at the bottom of my driveway,but I don't have heat down there,and I'm wondering if storing powder in a cold garage all winter will harm it..It's all in the plastic 1pound jugs..I live West Virginia,and we have a lot of freezing temps..Thank you
