A bit off topic here:
I have seen many reloading rooms showing a ABC type fire extinguisher. Everyone that has one raise your hand!!
You do realize that the household type extinguisher will do absolutely nothing to put out a powder fire??!!
Maybe if your radio or electric powder measure shorts out, but once powder burns your are SOL. Plus the extinguisher is usually mounted right at the bench., A powder fire would consume you before you even thought about grabbing it.

FIRE-FIGHTING MEASURES Suitable extinguishing media Large volumes of water should be applied as quickly as possible from automatic sprinklers or fire hose. Unsuitable extinguishing media Do not use water jet as an extinguisher, as this may spread fire
