A Fire extinguisher is a device which can be used to control a fire. Fire extinguishers can help remove the fire, and may stop it from burning. Depending on the size, some fire extinguishers can be carried around and operated by hand. There are different kinds of fire extinguishers. Different kinds of fire can be controlled by different substances. There are color codes, the color tells what kinds of fires the fire extinguisher is useful for:

There are also different sizes of fire extinguishers. Bigger fire extinguishers can be used for a longer time. Hand-held fire extinguishers vary between 0.5 and 14 kg. A 2 kg extinguisher works for about two to four seconds, the 12 kg model for about eighteen seconds. There are also bigger fire extinguishers, mounted on a cart or a vehicle.

To be useful, fire extinguishers need to be checked at regular intervals. Usually, there are laws about this duration, concerning fire extinguishers in public buildings.
