More often than not, ignorance on such matters results in worse case scenarios like using a water fire extinguisher to stop a fire caused by some electrical problems as this would make the fire bigger and more uncontrollable.
It is therefore not enough that you have one in your house or workplace but that you got the right one for the kind of fire that is likely to occur to safely put it out.
Since there are different kinds of fire extinguishers, you have to get the ones that would effectively and safely suit your needs.

For offices where there are lots of paperwork and computers, getting a water fire extinguisher and a CO2 extinguisher is a good combination so that you can have a suitable device for use for the solid materials and for the electrical equipment respectively.
