Parts of a Fire Extinguisher

 

Each separate parts of a fire extinguisher contribute to storing, expelling, or informing — knowing about each component will help you use it safely and effectively. Here are the parts of a fire extinguisher and how they work:

 

  • Cylindrical tank: This is the main body of the fire extinguisher, storing the extinguishing agent and propellant at the correct pressure. The tank is often made of steel, which makes it durable — even small tanks can be heavy.
  • Valve: The valve controls the release of the extinguishing agent and connects the handle and operating lever.
  • Carry handle: Used for carrying and holding the fire extinguisher, the handle allows for easy gripping, lifting, and carrying.
  • Operating lever: The handle that, when squeezed, activates the fire extinguisher. It requires the pull pin to be removed first before activating.
  • Pull pin: The metal pin that must be removed before operating the extinguisher. Also known as the locking pin, the pull pin prevents accidental discharge, such as when you accidentally squeeze the lever down while you’re only trying to carry the extinguisher.
  • Tamper seal: A plastic seal that keeps the pull pin in place so it doesn’t fall out accidentally.
  • Pressure gauge: The pressure gauge is a circular gauge mounted on the outside of the valve, indicating whether the extinguisher has sufficient pressure to release the agent. A needle in the green zone means it is properly charged. Note that CO2 extinguishers do not have pressure gauges.
  • Discharge hose: This hose allows the extinguishing agent to travel from the tank to the base of the fire and helps with aiming.
  • Discharge nozzle: Attached to the end of the hose, the nozzle controls the dispersing of the agent.

 

 

Of course, there’s also the extinguishing agent, or the chemical stored inside the tank that extinguishes the fire, as well as the propellant, or the gas that expels the agent from the tank. Understanding these parts can help you confidently use a fire extinguisher in an emergency.

 

At National Fire Supply, we provide a range of parts and accessories for fire extinguishers, from hooks and pull pins to covers and cabinets.

 

Informative Parts of a Fire Extinguisher

 

Along with the functioning parts of the extinguisher, there are also informative ones, including:

 

  • Instruction label: Properly functioning fire extinguishers will have a legible instruction label detailing how to use the extinguisher and the type of fire it can be used on.
  • Monthly inspection tag: This tag allows whoever is responsible for the monthly inspection to record the date of the monthly check and the initials of the person who inspected it. The tag helps you comply with your local fire protection regulations, and monthly inspections are required.
  • Annual inspection tag: This tag is where a professional fire and security provider records the date and important information about the required annual maintenance inspection of your fire extinguisher. This tag helps comply with local codes and make sure your extinguisher is getting the proper care to operate correctly when needed.
