Fire Safety - Sprinkler System.

Problem	Design	Construction	Maintenance
Faulty/compromised sprinkler system; Leaky sprinkler pipe; Obstructed sprinkler; Corroded and faulty sprinkler	Sprinkler design requirements should consider hydraulic principles and parameters such as hazard class, discharge density, and AMAO; (assumed maximum area of operation) in accordance with CP; 52, ISO 6182 series, NFPA 13 or equivalent. The usual requirement is 75 L/min for 2.5 m wide area.; Rust resistant material should be specified to avoid corrosion, pitting and scaling.; Potential obstructions should be considered during planning stage.	Installation and testing of sprinkler system, its associated controls, fire pumps and water supply should be guided by CP 52, NFPA 13 or equivalent.; Mounting should be carried out in accordance with manufacturer’s instructions. To adopt general guidelines in accordance with NFPA 13 or equivalent.; Sprinkler system should be carefully installed to maintain correct orientation without hindrance by supports.; Spare sprinklers and sprinkler spanner should be maintained after installation for future needs.	Conduct quarterly visual inspection of all sprinklers for any leakage, damages or grease/dirt in spray nozzle and replace as necessary.; Conduct annual inspection of pipes and hangers for corrosion and mechanical damage (clean, paint or replace as necessary).; Clean quarterly and remove any obstruction affecting efficient discharge from sprinklers. Check for any sign of corrosion or deposit of dirt, paint or foreign material in accordance with NFPA 13 or equivalent.; Practice good housekeeping to avoid stacking of material leading to obstruction of sprinklers.
