Help a newbie
I am so tired of mindless smart aleck answers I'm breaking a long self-imposed silence to post here. Mods, you might want to address those thoughtless members who somehow think it OK to give dangerous advice on your forum. Remember, the question was raised by someone so new to reloading, he thought he could get decent advice on CGN.
Clean up the spill with a broom, brushes, and even adhesive tapes. Do not use a vacumm cleaner, as there is a small risk of fire from spark. Just gently and thoroughly brush all powder into an open pan, and flush down the toilet. Think cleaning up a keyboard - small brushes, in between parts of the reloading tool, and maybe do a detailed disassembly to get it all. A simple broom will clean a hard floor, and sticky tape will get powder granules out of carpet or textured flooring. The fire hazard is not great, but smokeless powder fires are impressive, and no one wants the fire department hosing down their gun rooms! Oh, and make sure you close and move clear any powder containers before you start the clean-up. Limiting the amount of fuel available is always prudent in any potential ignition situation.
