4 General requirements
4.1 General requirements
4.1.1
The laying of hydraulic piping should be kept away from the oxygen supply system. If unavoidable, take necessary measures to prevent danger (such as oxygen or hydraulic oil).
Leakage caused fire, etc.).
4.1.2
The installation of large-scale supply and use equipment (such as motors, battery packs, etc.) should be avoided in the vicinity of the oxygen supply system. If unavoidable, it should be taken as necessary.
Measures to prevent danger (such as oxygen leakage accelerate the motor aging or hydrogen explosion from the battery, etc.).
4.1.3
The power supply equipment should be able to meet the demand for electricity during all working hours of oxygen supply and carbon dioxide absorption equipment.
4.2 Equipment Selection Requirements
4.2.1
All equipment materials should be flame-retardant and asbestos materials should not be used.
