I heard about a part time employee who absentmindedly
leaned on a dry chem unit that was hanging on the
wall. The resulting discharge shut down the fast food
restaurant for the rest of the day for cleaning.

I know a guy who set off the Ansul system in his restaurant. In the
process of cleaning up the mess, he threw out all of the food in his
walk-in and freezer. The next day he found out that the "chemical"
was baking soda. D'oh!

The opposite; a cow-orker had a kitchen fire and used a dry-chemical
FW to put out the fire. The chemical ruined every switch and piece of
electronics in the house. When the insurance agent found out what
happened, he said it would have been better to do nothing.
