What are the common inspection items for stationary CO2 fire extinguishing systems?

1. Are the crew members familiar with the CO2 fire suppression system operating system?

2. Is a fixed fire suppression system installed in the paint shop?

3. Is the ship equipped with a fixed CO2 system? If not, is there a corresponding exemption certificate?

4. Is the CO2 room equipped with the operating instructions for the system?

5. Is the deck between the CO2 room and the engine room insulated to A-60?

6. Does the fire separation between the CO2 room and adjacent compartments or decks meet the requirements?

7. The floor of the CO2 room is of A-60 construction, but are the piping systems extended with a 450mm fireproof extension?

8. Is the emergency lighting in the CO2 room functioning properly?

9. Is the acoustic telephone between the CO2 compartment and the bridge functioning properly?

10. Is a readily available fire extinguisher placed at the entrance to the CO2 compartment?

11. Is the mechanical ventilation system in the CO2 compartment functioning properly?

12. Is the CO2 compartment free of clutter?

13. Are the reports on the CO2 cylinder weighing and piping purging (air tightness test, hydraulic test) for the CO2 system valid?

14. Are the markings on the CO2 cylinders clearly and permanently displayed?

15. Is the quantity of extinguishing agent in the CO2 system sufficient to meet the dosage requirements for protecting the largest compartment?

16. Is there equipment available to monitor the quantity of extinguishing agent in the CO2 cylinders?

17. Is the key to the CO2 release device placed in a box without a glass panel, and is this box placed in a conspicuous location near the release device?

18. Are feasible measures taken to ensure the activation sequence of the CO2 release device?

19. Are the protected locations marked on the CO2 system piping?

20. Is the safety pin on the CO2 system cylinder valve removed?

21. Are there any loose connections at multiple joints on the CO2 system cylinder valve activation pipe?

22. Is the pressure in the CO2 system cylinder valve activation cylinder sufficient?

23. Is a check valve installed on the connecting pipe from the CO2 system cylinder valve to the manifold?

24. Is the CO2 system cylinder valve activation piping directly connected to the release valve activation pipe, and can the two sets of activation control devices be independent of each other?

25. Are the connecting pipe joints between the CO2 system cylinder valve and the manifold loose and leaking?

26. Is a pressure gauge with a range of 0-24.5 MPa (modified to 1.5 times the working pressure gauge for the Hai 16 model) installed on the main pipe from the CO2 system manifold to the distribution valve box?

27. Does the ship have spare parts such as cylinder valves and hoses?

28. Is the valve core of the CO2 system's release valve for protecting the engine room jammed or in a closed state?

29. Does the audible alarm device before CO2 system release function automatically?

30. Is the audible alarm time before CO2 system release less than 20 seconds or is there no pre-release alarm?

31. Is the audible alarm for CO2 system release pre-alarm distinguishable from other alarms?

32. Can the CO2 system release pre-alarm be powered by an emergency power supply?

33. Is a time delay device installed in the CO2 system release system?
