Method for protecting an area against pollution by using a cloud of water droplets
First Claim
1. Method for protecting an area, against pollution by forming a cloud of water droplets, which may contain an additive, over the area to be protected the method comprising at least two of the three following stages, in an order which is predetermined:
- a) a stage in which the droplets formed essentially have a diameter less than 100 micrometers,b) a stage in which the droplets formed essentially comprise 10 to 50% by weight of droplets of a diameter less than 100 micrometers, and the remainder of droplets of a diameter between 100 and 300 micrometers,c) a stage in which the droplets formed comprise 3 to 20% by weight of droplets of a diameter less than 100 micrometers, 20 to 50% by weight of droplets of a diameter between 100 and 300 micrometers, and the remainder of droplets of a diameter between 300 and 800 micrometers.

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.
