Staircases, shafts, balconies, and other open building spaces.Wall or ceiling surfaced with non-combustible material.Closets, pantries and other non-dwelling spaces lesser than 2.2m 2.Sprinklers are required in every building spaces other than the following as specified by NFPA NFPA also recommends an average of the recommended spacing as the maximum between sprinkler and wall or obstruction deeper than 350mm, while special considerations should be given to custom ceilings. Ordinarily, NFPA recommends the standard spacing for each sprinkler head according to the hazard classification to achieve an efficient fire sprinkler system. On this note, building services professionals do recommend a spacing of 3.7m between two heads. The Wall type sprinkler, for example, has an average of 4.2m straight throw from the centerline with extensive coverage of 70’. The installation types also determine the spray of the sprinkler head, which NFPA has rules for. The Standard sprinkler head has a maximum coverage area of 15m 2 while the Extended spray sprinkler head has a maximum coverage area of 18m 2. The head type varies from a standard type sprinkler head to an extended type sprinkler head.
Sprinkler head spacing is a factor of the head type, installation type, and the building hazard classification. Having gotten the category the building you are to design falls we now proceed to the second stage of the design process Sprinkler Head Spacing On this note, fire-fighting engineers classified every building project into three, based on the degree of fire effect.
Determination of the head spacing requirementĮver since time, building services professionals do classify every building project into a category to provide related services to every building as required.Determination of the building hazard classification.The system is based on the sprinkler head, which should not be too close to obstacles nor each other, the control station, and an accurately sized pipe to avoid fire spread.īuilding services Professionals thus outline the following five steps in achieving an efficient fire sprinkler system: The system design needs to be handle by a versatile mechanical building services engineers or sometimes by specialized fire-fighting professionals. Fire sprinkler system being an essential type of fire suppression system is an automatic system for controlling fire at its incipient stage.
