Safe to store?
I am wondering if there is any danger of spontaneous ignition of these two. They are signal star flares, and they are split open. I generally dont worry about ammo (I have a lot of shooting ammo on hand…), but these do make me want to ask the EOD guys here. Thank you. CIL 10 CANUCK...
