Safety Technical Conditions of LPG Cylinder Filling Station
Liquefied petroleum gas (LPG) cylinder filling station refers to a set of public gas equipment which is used to fill LPG into LPG cylinder and LPG cylinder (bottle). This safety technical condition is limited to aboveground cylinder filling station.
I. General Requirements:
1.1 Cylinder filling station should ensure the implementation of relevant laws and regulations, standards and other norms.
1.2 The cylinder filling station should be equipped with corresponding fire-fighting facilities, and complete fire-fighting measures should be adopted in the process of building and operation.
1.3 Cylinder filling station and its pipelines system should be installed at a certain height from the ground or below the nearby surface ground and away from the buildings or residences, and should not be placed in a water source or buried.
1.4 During the operation of cylinder filling station, the operator should be equip with automatic extinguishing device.
II. Site Requirements
2.1 Geographical location must conform to the stipulates of national laws and regulations , the site of cylinder filling station should pre-avoid flood, landslide and soil erosion and other areas which not suitable for construction construction.
2.2 The site of cylinder filling station should have enough space to load LPG tank and other gas transportation containers, and the isolation distance between each type of containers should not be less than 10 meters.
2.3 The site of cylinder filling station should be pre-avoiding airway, railway lines, water ports, public places, religious venues, schools and other sites which have potential safety hazards.
III. Fire-fighting Equipment Requirements
3.1 Cylinder filling station should be equipped with mechanical type fire extinguisher, automatic fire extinguishing extinguishing, chemical foam or water spray system or fire-fighting tank.
3.2 Mechanical type fire extinguisher and fire-fighting tank should meet the requirements of the corresponding national standards.
3.3 Manual fire extinguishing equipment should be placed in the required locations and distributed according to the gallons of LPG used for compounding and volume of the cylinder filling station.
3.4 For large-scale cylinder filling station with large LPG tank and high storage capacity, water- or fire-fighting pump with fire engine should be equipped.
IV. Building Requirements
4.1 Cylinder filling station building should meet the fire protection requirements and should have sound walls and interior and exterior surfaces which are made up of non-flammable materials.
4.2 The cylinder filling station building should be separate from the filling cabin and sentry cabin, and should have at least four exits which can be used for evacuation.
4.3 Cylinder filling station should be equipped with a ventilation system which can send out internal gas.
V. Equipment Requirements
5.1 Cylinder filling station should be equipped with self-closing valves and pressure regulating valves.
5.2 Cylinder filling station should be equipped with safety devices such as Excessive flow alarm, Emergency stop switch and Leak detection device.
5.3 The cylinder filling station should be provided with necessary measurement and monitoring instruments such as differential pressure gauge, temperature and pressure instruments, weighing instruments, flow meter, etc.
5.4 The fire-fighting equipment should be regularly maintained and the function of the safety devices should be checked in time.
VI. Management Requirements
6.1 The cylinder filling station operator should have the corresponding gas safety professional technical personnel, and should provide training and examination for the related personnel.
6.2 The operator should work out the operational procedures in order to manage the whole process safely, and strictly observe the operational requirements.
VII. Test Requirements
7.1 Cylinder filling station should be periodically tested in order to ensure its safety.
7.2 Pressure test of pipeline and storage equipment should be performed at least once a year.
7.3 Check and testing of the fire-fighting equipment should be performed at least once every two years.
7.4 Leakage test should be performed before and after cylinder filling, and the test result should be recorded and kept.
These safety technical conditions of cylinder filling station is limited to aboveground cylinder filling station, and the site and construction design should refer to the relevant national standards. The safety of cylinder filling station should be ensured through comprehensive strength, and the operators and technical personnel should strictly observe these safety technical conditions in order to ensure public safety.
