What are the explosion-proof requirements for the room where oxygen cylinders are stored?

1 Gas cylinders should be stored in outdoor areas with shading and canopies. When stored indoors, the building must meet relevant standard requirements. The storage area for gas cylinders must not be located in basements or semi-basements, nor should it be adjacent to offices or rest areas. 2 The storage area must be well-ventilated and dry, protected from rain (snow) and water exposure, as well as direct sunlight. Open flames and other heat sources are strictly prohibited; there should be no ditches, hidden passages, or ventilation holes at the bottom, and no pipelines are allowed to pass through this area. 3 In warehouses where flammable or explosive gas cylinders are stored, the lighting equipment must be explosion-proof. Electrical switches and fuses should be placed outside the warehouse, and lightning protection devices must also be installed. It is forbidden to place gas cylinders in areas that may conduct electricity. 4 Gas cylinders should be stored separately by category, with labels attached. Empty cylinders and full cylinders must be kept apart. Cylinders containing oxygen or other oxidizing gases should be stored separately from fuel cylinders and other flammable materials, with at least a 6-m distance between them. There should be no flammable items, oil stains, or other debris around oxygen cylinders. It is strictly prohibited to store acetylene cylinders together with oxygen cylinders, chlorine cylinders, or flammable materials. Cylinders containing toxic gases, or those whose contents can cause combustion, explosion, or the release of toxins, must be stored in separate rooms, with antidote kits and appropriate fire-fighting equipment available nearby.

It is used only for storing oxygen, indoors; the room needs to be connected to electricity. How should I determine the explosion-proof standards for such a room?
