Abstract
Method for protecting an area, in particular against fire, by emission of a cloud of water droplets, comprising at least two of the three successive stages, in an order which is appropriate to the problem faced: a first stage, corresponding to remote fire prevention, in which droplets are emitted which are smaller than 100 micrometers, suitable in particular for rehydrating plants, a second stage, used in proximal prevention, which comprises in addition the emission of droplets of 100 to 300 micrometers, giving a more long lasting mist, and a third stage, for immediate prevention, in which droplets of 300 to 800 micrometers are added to the previous droplets, for a drizzle effect.
