11. Requirements for Protection Zones
 Size Limitations: The size of a single protective area is restricted to a maximum of 800m2, with a
volumenotexceeding3600m3.Adheringtotheselimitsensuresthatthereextinguishingsystemcan
eectivelysuppressreswithinthedesignatedarea.
 Fire Resistance Requirements: The enclosure structure, doors, and windows of the protective zone
shouldpossessaminimumreresistancelimitof0.5hours.Additionally,theceilingshouldhaveare
resistancelimitofatleast0.25hours.Thesereresistanceratingsprovideaspeciedtimeframeduring
whichthestructurecanwithstandre,enablingsafeevacuationandminimizingrespread.
 Enclosure Structural Strength: The enclosure structure within the protected area must have the capa-
bility to withstand internal pressure and bear a minimum pressure of 1200Pa. This requirement ensures
thatthestructureremainsintactandpreventsthespreadofre,smoke,andgasestoadjacentareas.
 Pressure Relief Ports:Tomanageinternalpressureduringresuppression,pressurereliefportsare
essential. These ports should be positioned at least two-thirds of the clear height of the protective zone.
They facilitate the controlled release of pressure while preventing structural damage or failure, enhanc-
ing safety and maintaining the structural integrity of the protected area.
 Self-Closing Openings: Except for pressure relief vents, all openings in the protected area should have
thecapabilitytoautomaticallyclosethemselvesbeforethereextinguishingagentisreleased.Thisfea-
turerestrictsthespreadofre,smoke,andgasestootherareas,containingtherewithinthedesignat-
ed space.
 Evacuation Passageways and Exits: Adequate passageways and exits should be provided within the
protected area to ensure swift and safe evacuation. These pathways must allow for the complete evacu-
ation of occupants within 30 seconds, enabling a timely escape during an emergency.
 Emergency Lighting and Evacuation Signs: Evacuation channels and exits within the protected area
should be equipped with emergency lighting and clear evacuation indication signs. This facilitates safe
movement and helps occupants navigate the escape routes, even in low visibility conditions caused by
smoke or power outages.
 Evacuation-Friendly Doors: Doors within the protected area should open in the direction of evacuation
and possess the ability to close automatically. This design feature streamlines the evacuation process
by providing unobstructed pathways and ensuring that doors are closed behind evacuating occupants,
preventingthespreadofreandsmoke.
 Galvanized High-Pressure Steel Pipe Fittings:Pipettingswithinthesystemareconstructedusing
high-pressuresteelpipettingsthataregalvanizedonboththeinsideandoutside.Thisgalvanized
coatingprotectsagainstcorrosion,extendingtheservicelifeofthettingsandensuringtheirdurability
under high-pressure conditions.
12. Pressure Relief Port in Protection Zone
To determine the pressure relief port size in the protection zone, the DA formula can be used. Here's an
improved explanation incorporating all the points.
 Pressure Relief Port Size Calculation: The size of the pressure relief port in the protection zone can be
determined using the DA formula: Fx = 0.15Qx / (Pf^0.5).
 Qxrepresentstheaveragereleaserateofthereextinguishingagentintheprotectedarea,meas-
ured in kilograms per second (kg/s).
 Pf denotes the allowed internal pressure that the enclosure can withstand, measured in Pascals (Pa).
