Fire extinguishers are our silent heroes when it comes to fire protection. But what exactly is inside these handy devices that can save lives in an emergency? In this article, we take a look at the structure of a fire extinguisher.
A fire extinguisher basically consists of the following components:
The fire extinguisher design also differs depending on the type. In a rechargeable fire extinguisher, the propellant gas and the extinguishing agent are stored separately. A rechargeable fire extinguisher also has the following components:
Good to know: There are also rechargeable fire extinguishers that hold the extinguishing agent (foam) in a separate cartridge.
The extinguishing agent is therefore only mixed with the water in the container when the extinguisher is activated. This makes maintenance and disposal easier and more environmentally friendly.
In contrast, the propellant gas and the extinguishing agent are stored together in the container of a permanent pressure fire extinguisher. The extinguisher is constantly under pressure, so it is immediately ready for use without the fire extinguisher having to be activated.
A permanent pressure fire extinguisher also has the following components.
The design of CO2 fire extinguishers differs from classic rechargeable and permanent pressure fire extinguishers, which use foam, powder or water. With CO2 fire extinguishers, the extinguishing agent also serves as a propellant gas.
In addition, CO2 fire extinguishers are equipped with a funnel-shaped nozzle or a snow pipe instead of an extinguishing hose with an extinguishing nozzle or gun.
