A method in the fire protection of an area, in which in the area are arranged several fire extinguishing spraying heads (1) which, when activated, spray extinguishing medium in the area, and between which adjacent spraying heads there is a spacing (S1, S2). The spraying heads (1) are arranged in the area (A1, A2) by defining a water flux density of extinguishing medium required for protecting the area being protected and by defining feed pressure (p1, p2) of extinguishing medium for the spraying heads (1) of a certain area or section of an area, whereby the spacing (S1, S2) of adjacent spraying heads depends on the magnitude of the feed pressure (p1, p2) and a K value of the spraying head so that the water flux density of extinguishing medium intended for spraying is substantially constant. The invention also relates to an apparatus.
