I have two young ones at home. I do all of my casting in the garage and do a thorough cleanup afterwards. I do most of my casting during the winter months- the air is dryer, and its not as uncomfortable to wear pants, boots, jacket, hat, and welding gloves as it is in warmer months and I can drop my bullets into a bucket of snow. Cover up as much of your exposed skin as possible- burns are no fun. A wide brim hat will give you protection from the inevitable 'lead geyser' if you accidentally introduce moisture into your pot (happened to me once using Marvelux, no longer use that crap with the amount of sawdust I have handy), the hot lead goes nearly straight up and then rains down on you in a blink of an eye.
