Foam fire extinguishers work by creating a film over the flames that suffocates the fire. They contain AFFF, or Aqueous Film Forming Foam, an ideal substance for spraying on Class A and B fires, so you can use just one extinguisher to cover both wood, paper and fabric fires, or flammable liquids fires (except cooking oils).

AFFF foam extinguishers are therefore a great choice for today's office environment, as not only are they highly effective, but they also weigh less than their water-filled cousins! A special nozzle ensures that even if you accidentally spray live electrical equipment with the foam, you will not get an electric shock conducted up the nozzle. They are best combined with a CO2 extinguisher.
