I actually don't plan on storing them indoors but was curious is I did, I have about 150lbs of WW ingots and was wondering if the actual lead itself has any danger if I am not touching it, etc. I assume there is no way for it to get airborne unless there were a little dust on it so are there any rules for actual storage and safety? I hear about people with mass amounts coating with a sprat but that seems unnecessary but is also why I decided to ask. No I don't have kids just to clear that up for the "indoors" part
