Introduction
1. Background of standard formulation and technological evolution
GB/T 34424—2017 "Equivalent water-based fire-fighting system for ships" is an important standard for ship fire safety in China, aiming to ensure the safety of personnel and equipment on board. With the advancement of ship technology and the improvement of firefighting requirements, this standard came into being and replaced the old version of the standard to meet more complex fire prevention and control needs.
2. Comparison of standard frameworks
| Standard dimensions | GB/T 34424—2017 | Old version of the standard | International comparison |
|---|---|---|---|
| Design specifications | Clearly define the zoning design of the fire extinguishing system and require the system to have immediate startup capability | The design requirements are relatively general | In line with the IMO Convention |
| Performance parameters | Key parameters such as extinguishing agent flow, pressure, and nozzle arrangement are clearly quantified | Parameter requirements are not specific enough | Consistent with international standards |
| Test methods | The test process under different fire scenarios is refined, and more stringent evaluation indicators are introduced | The test requirements are relatively simple | Comply with IMO MSC/Circ.1236 guidelines |
3. Interpretation of the core content of the standard
3.1 Fire extinguishing system design requirements
Partition independence: The fire extinguishing system needs to be divided into several independent partitions to ensure that the failure of one area does not affect other areas.
Water supply: The system must be equipped with a permanent seawater inlet and have the ability to be used continuously. The seawater inlet should be reasonably arranged to avoid cutting off the seawater supply to the water pump during inspection or repair.
3.2 Key Performance Indicators
3.3 Fire extinguishing system protection requirements
Electrical component protection: The electrical components on the pressure source should meet the protection level of IP44 in GB/T 4208-2017 to ensure resistance to vibration, moisture and salt spray corrosion in the ship environment.
