Merriam-Webster. (2004), The Merriam-Webster Dictionary. In New York:
A fire extinguisher is a portable container usually filled with chemicals for putting out fires. (Merriam-Webster, 2004) An active fire protection device used to extinguish or control fires. Fire extinguishers are mostly used in emergency situations, and is not intended for an out of control fire. Fires that get out of control normally need the expertise of a fire department. Trying to put out a fire by yourself, can only cause you harm unless you know what you are doing. “Typically, a fire extinguisher consists of a hand-held cylindrical pressure vessel containing an agent, which can be discharged to extinguish a fire. “ (Nadar, 2010`) Fire needs fuel oxygen and heat to burn. Fire extinguishers help to put out fires by either by applying an agent that cools the burning fuel, or displaces the surrounding oxygen, depending on the type of fire extinguisher that you use. There are many different types of fire extinguishers, each meant to put out a certain type of fire, which I will talk about later.
How a fire extinguisher works. Pulling out the body pin, and depressing the lever at the top of the cylinder release the material in the extinguisher released by high amounts of pressure. “At the top of the cylinder, there is a smaller cylinder filled with compressed gas. A release valve acts as a locking mechanism and prevents this gas from escaping. When you pull the safety pin and squeeze the lever, the lever pushes on an actuating rod which presses the valve down to open a passage to the nozzle. The compressed gas is released, applying a downward pressure on the fire-extinguishing material. This pushes the material out the nozzle with high amounts of pressure.” ("Fire
