Ever discharge a fire extinguisher indoors?

[Paul Sandhu]

I was picking up a box of spilled ammunition in my pantry and getting back up.  While doing that my hand pressed down on the discharge lever of a fire extinguisher.  It only discharged for about 1/10 of a second, but that dry powder went everywhere.  Every little nook and cranny, inside paper bags, over canned goods, all over stacks of plates, and all over an O/U shotgun.  I cleaned off the gun first, then used a vacuum to clean up the powder that was everywhere.  My cleaning lady was laughing at me the whole time.
