A fire can break out anywhere, completely unexpectedly. When it does, youll need to respond as fast as possible to extinguish the fire. Having a fire extinguisher always on hand will make sure that small fires dont break out into larger structure fires or worse. There are many different kinds of extinguishers. Some are made for electrical or grease fires specifically, while others are capable of handling multiple tapes of ignition. Purchase models based on possible sources of fire.
