To prevent hazards caused by static electricity in liquid oxygen tanks, the following measures can be taken:
Grounding: Ensure proper grounding of the liquid oxygen tank and related equipment. Grounding releases static electricity to the ground, reducing the likelihood of static buildup. Metal components such as tanks and pipes should be connected to a reliable grounding system.
Static dissipative materials: Utilize static dissipative materials to reduce the accumulation of static electricity. For instance, apply conductive coatings or materials on the insulation layer of liquid oxygen tanks and pipelines to discharge static electricity to the ground.
Static Dissipative Equipment: Utilize static dissipative equipment, such as static conductive pipes and hoses, to reduce the accumulation and discharge of static electricity. These devices help to ground static electricity, minimizing the occurrence of static sparks.
Static grounding wire: Install static grounding wires on liquid oxygen storage tanks and related equipment to discharge static electricity to the ground. These grounding wires should be connected to a reliable grounding system and be inspected and maintained regularly.
Electrostatic Discharger: Utilize an electrostatic discharger to neutralize static electricity. These devices can neutralize static by releasing opposite charges, reducing static buildup and spark generation.
Electrostatic Safety Training: Provide electrostatic safety training for personnel using liquid oxygen storage tanks, enhancing their awareness and prevention of electrostatic hazards. Training content can include the principles of electrostatic formation, preventive measures, and emergency response procedures.
It is essential that the static prevention measures for liquid oxygen storage tanks be designed and implemented by personnel, adhering to the relevant safety operating procedures and standards. During operation, strict adherence to the prescribed operational procedures is required to avoid the generation of static sparks, ensuring the tank's safety.

Proper placement of liquid oxygen tanks is a crucial measure to ensure they pose no danger to the surrounding environment and personnel during use. The following are the safety requirements for the placement of liquid oxygen tanks:
Safety Distance: Liquid oxygen tanks should maintain a certain distance from other buildings and equipment. This is to ensure effective control and reduction of environmental impact in case of leaks or fires.
Fire and Explosion Prevention Measures: Liquid oxygen tanks should be placed in fire-resistant areas, away from open flames, high-temperature sources, and flammable materials. The surrounding area should be equipped with fire and explosion prevention facilities, such as fire extinguishers, foam sprinkler systems, etc., to address potential fire risks.
Level placement: The liquid oxygen tank should be placed on a sturdy, flat foundation to ensure stability. The bottom of the tank should make full contact with the ground to prevent the tank from tilting or swaying.
Ventilation Requirements: Liquid oxygen tanks should be placed in well-ventilated areas to ensure the normal circulation of gas emissions and oxygen supply. There should be no obstructions around the tank that hinder gas flow.
Identification and Warnings: Oxygen liquid storage tanks should be clearly marked with information such as the stored medium, capacity, and pressure. Warning signs and safety alerts should be placed in the surrounding area to remind personnel of the presence and potential hazards of the oxygen liquid storage tank.
Regular Inspections and Maintenance: Liquid oxygen tanks should be regularly inspected and maintained, including checking the tank's appearance, sealing, and corrosion prevention measures. Any issues found should be promptly repaired or the tank replaced to ensure proper operation and safety.
Note that the safety requirements for the placement of liquid oxygen tanks may vary depending on different regions and industries. When placing liquid oxygen tanks, adhere to relevant regulations, standards, and safety procedures, and develop appropriate safety measures based on the actual situation. If you are unfamiliar with or have questions about the safety placement requirements, it is recommended to consult with experts or relevant organizations.

Proper installation of the liquid oxygen safety valve is a crucial step in ensuring the safe operation of the liquid oxygen tank. Here are the installation steps for the liquid oxygen safety valve:
