3 Terms and definitions
The terms and definitions defined in GB/T 24499 and the following apply to this
document.
3.1 storage and transportation systems for gaseous hydrogen
Gaseous hydrogen storage systems, gaseous hydrogen transportation systems, gaseous
hydrogen compression systems, gaseous hydrogen filling systems, and their combined
systems.
3.2 stationary storage systems for gaseous hydrogen
Gaseous hydrogen storage systems with fixed installation and use locations.
3.3 mobile storage systems for gaseous hydrogen
A gaseous hydrogen storage system mounted on one or more movable bases.
3.4 safety accessories
Safety devices installed on the system or equipment to ensure the safe operation of the
system, including overpressure relief devices, emergency shut-off devices, safety
interlock devices, flame arresters, etc.
4.2 Overall design
4.2.1 Location
4.2.1.1 The fire protection distance between the system and buildings and structures
outside the system shall comply with the requirements of GB 50177 and GB 50516.
4.2.1.2 The laying of hydrogen pipelines shall comply with the provisions of GB 50177
and GB 50516.
4.2.1.3 The system shall be isolated from the storage systems of flammable gases,
oxygen, halogen gases, etc., and shall comply with the requirements of relevant
specifications and standards.
4.2.2 Plane layout
The system's layout shall comply with the requirements of GB 50177, GB 50516 and
GB/T 29729.
4.2.3 Buildings
4.2.3.1 The building where the system is installed shall be a single-storey building with
a fire-resistance rating not lower than Class II and a lightning protection classification
not lower than the secondary lightning-proof building.
4.2.3.2 Open flame heating is strictly prohibited in the explosion hazard area of the
system.
4.2.3.3 Fire-fighting equipment and fire-fighting water supply systems shall be installed
in the system area in accordance with the provisions of GB 50516 and GB 50177.
4.2.3.4 Explosion-hazardous areas of the system, especially at the entrance, shall be
marked with permanent signs in accordance with the provisions of GB 2894 to indicate
their dangers, such as hydrogen-flammable gas, and open flames strictly prohibited.
4.2.3.5 There shall be no debris in the explosion hazard area of the system to ensure
that the fire escape passages are unobstructed.
4.2.3.6 Rooms with explosion hazards within the system shall meet the following
requirements:
a) There shall be good ventilation in the room; the inner surface of the ceiling
shall be flat, and dead corners shall be avoided, and hydrogen shall not
accumulate;
b) The pressure relief facilities shall be installed on the exterior wall or roof, and
the calculation of the pressure relief area shall comply with the provisions of
GB 50516;
c) Rooms with explosion hazards shall not be directly connected to rooms
without explosion hazards. If they must be connected, they shall be connected
