Abstract
A method for fighting a fire sprays a liquid fog in a total action space (1; 21) about the fire by means of at least one spray head and sprays a non-combustible gas within a partial space (3; 3a; 23) which is within and small in relation to the volume of the total action space (1; 21). The non-combustible gas is used, in addition, as propellent gas for at least one hydraulic accumulator (10; 14; 30) for spraying of the liquid fog. The spraying of the non-combustible gas is initiated at least essentially simultaneously with the spraying of the liquid fog.

Method for fighting fire, comprising
- spraying a liquid fog in a total action space (1;
- 21) by means of at least one spray head,
- spraying within a partial space (3;
- 3a;
- 23) which is small in relation to the volume of the total action space (1;
- 21) a non-combustible gas
- using the non-combustible gas, in addition, as propellent gas for at least one hydraulic accumulator (10;
- 14;
- 30) for producing the liquid fog and
- initiating the spraying of the non-combustible gas at least essentially simultaneously with the spraying of the liquid fog.
Method for fighting fire, comprising
- spraying a liquid fog in a total action space (1;
- 21) by means of at least one spray head,
- spraying within a partial space (3;
- 3a;
- 23) which is small in relation to the volume of the total action space (1;
- 21) a non-combustible gas
- using the non-combustible gas, in addition, as propellent gas for at least one hydraulic accumulator (10;
- 14;
- 30) for producing the liquid fog and
- initiating the spraying of the non-combustible gas after the propellent gas pressure, in a container (11;
- 32) for the purpose, has fallen to a predeterminable value.
Installation for fighting fire, with at least one spray head (25) for producing a liquid fog in an action space (1;
- 21) and with a gas driven drive unit comprising propellent gas, wherein at least part of the propellent gas is arranged to be fed to gas nozzles (9;
- 27;
- 40) positioned within at least one locally restricted partial space (3;
- 23) of the action space (1;
- 21) of the installation.
