12. Fixed gaseous fire suppression systems Carbon dioxide  Over eighty years  Extinguishes the fire primarily by reducer the oxygen concentration and provides localized cooling  Local application and total flooding application

13. Fixed water system Water mist  90% droplets less than 1 mm in diameter  To cool the fire source by removing the heat and suppressing the fire  Displaces oxygen in the atmosphere

14. Design and installation Complex and various of size Type of fuel High value asset Temperature Downtown Integration Safety

15. Maintenance Regular maintenance by competent, third party certified person Manufacturer instruction Charges to protection area Enclosure integrity Nozzles position

16. Quality Design : Factory trained and certified engineer Component : US DOT, EU TPEP and PED System : UL, FM Global, LPCB and Vds Installation : NFPA 2001, ISO 14520 and the manufacturer instruction
