of Fire Fighting system for the “Proposed Villa Compound at Wakra“. The obecti!e of this document is to pro!ide Design Philosophies and Calculations to ensure an e"cient and reliable performance for the facilities Fire Fighting system in accordance #ith $FP% Codes and the &atar Ci!il Defense Department 're safety re(uirements. II.
GENERAL SUMMARY :-
%. The Fire 'ghting system for the “Proposed Villa Compound at Wakra) shall be designed in accordance #ith the mandatory re(uirements for safety and loss pre!ention as prescribed by $FP% Codes and the &atar Ci!il Defense Department 're safety re(uirements. *t is the obecti!e of this document to ensure that safe design is achie!ed and to minimi+e the risk of inury to personnel, loss or damage to property and structures and pollution to the en!ironment. -. %de(uate Portable 're etinguishers shall be installed in Villa/s, Club house, 0uard room, Pump room, substations and areas #here!er re(uired is in accordance #ith $FP% 1. Fire blanket shall be pro!ided for kitchen and pantry. C. The Clubhouse in the Villa compound is protected #ith automatic sprinkler system and a hose system is pro!ided and is in accordance #ith $FP% 12 and $FP% 13. %utomatic sprinkler system and 're etinguisher shall be pro!ided for 're pump room. D. Fire Water for the sprinkler system and hose system is ser!ed by means of Fire pumps set located in the underground 're pump room and t#o underground Fire #ater tank. 4. Calculations summary shall be prepared for the proposed building sho#ing the re(uired demand residual pressure and 're #ater 5o# of the 're pumps #hich feeds the main pipe entering the building assuming a 're e!ent has occurred on one area of the building. This feed main pipe #ill supply the #ater source for an automatic sprinkler system design of the building. F. *dentifying the correct demand #ater 5o# and pressure at the feed main pipe #ill ensure an e"cient and reliable performance of the 're'ghting piping layout considering the most hydraulically demanding area of the building by specifying the minimum end head condition of the remotest sprinklers and one 're hose reel in
