  • Fire extinguishers designed as portable fire extinguishers usually serve for the immediate fight against incipient and small fires and must be able to be handled by inexperienced people.
  • Fire extinguishers are generally subject to approval and have a pressure-resistant container that contains the extinguishing agent and usually also the propellant gas. By actuating a firing pin or a valve, the propellant becomes effective and pushes the extinguishing agent out through the spray nozzle.
  • Liquid and vaporous substances as well as multi-phase systems such as foams and powder clouds are used as extinguishing agents.
  • the mode of action of an extinguishing agent is based on suffocation, ie suppressing the supply of oxygen, cooling, for example by evaporating water, and / or inhibiting the combustion reaction.
