Purpose of a Fire Extinguisher? The parts and components of a fire extinguisher , all play a vital role in the effective discharge of water or a chemical agent to suppress a fire before it can spread out of control leading to property damage and maybe even loss of life.
The Fire Triangle Fire extinguishers are engineered to spray and spread an agent on a fire to remove one of the three elements necessary to maintain a fire once it has started. Those elements are: 1- Fuel : The source of fuel that is burning 2- Heat: The Heat that is produced by the fire 3- Oxygen : The Oxygen that is needed to keep the fire going
Parts and Components Parts Descriptions of each part or component Cylindrical Tanks Flat on the bottom and dome shaped on top, cylindrical steel tanks contain the extinguishing agent and the propellant necessary to provide the pressure to forcibly push the fire extinguishing agent out creating a spray. Valve Assembly The function of the valve is to control or regulate the flow of the extinguishing agent. It consists of a machined body made of metal bar stock on a lathe (or plastic injected molded part for economy versions), a handle that allows for grasping and lifting and transporting the extinguisher, a metal locking pin to prevent against accidental discharge, Plastic tamper seals to keep the locking pin from falling out, a metal release lever and a dip tube through which the agent is drawn up for expulsion. Stored pressure fire extinguishers may also contain a pressure gauge . Nozzle and/or Hose: A nozzle directs the direction of the extinguishing agent as it leaves the tank. A hose, typically found on extinguishers that are heavier than 3 kg, further allows refined directing of the flow as it leaves the extinguisher. Extinguishing Agent The substance that limits or suppresses the spread of the fire Propellant A gas whose function is to expel the extinguishing agent from the fire extinguisher.
