NOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO !!!!!!!!!!!!!!
Bruno, do yourself a BIG BIG favor and throw that thing away !!!!
It is a powder extinguisher and they are doing more harm than good. If you spray that thing empty on something you can throw it away, whatever it was before....
Seriously, invest a bit more, powder extinguishers are cheap but they ruin materials just as much as any fire would ! Get a CO2 extinguisher instead.
CO2 extinguishers are best for electrical fires, which is pretty much what we risk in our gamerooms. (DO go outside after you have used it up though, fire out or not).
