To prevent the danger caused by static electricity in liquid oxygen storage tanks, the following measures can be taken:
Ensure proper grounding of the liquid oxygen storage tank and related equipment. Grounding helps release static electricity to the ground, reducing the likelihood of static buildup. Metal components such as tanks and pipelines 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 to the insulating layer of liquid oxygen storage 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 minimize the accumulation and release of static electricity. These devices assist in grounding static electricity, reducing 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.
Static Eliminators: Utilize static eliminators to dissipate static electricity. These devices neutralize static by releasing opposite charges, reducing static buildup and spark generation.
Electrostatic Safety Training: Provide electrostatic safety training for personnel using liquid oxygen tanks to enhance their awareness and preventive measures against electrostatic hazards. The training content can include the principles of electrostatic formation, preventive measures, and emergency response procedures.
It is essential that the electrostatic prevention measures for liquid oxygen storage tanks be designed and implemented by personnel, following relevant safety operating procedures and standards. During operation, strict adherence to the prescribed operational procedures is required to prevent the generation of static sparks, ensuring the safety of the storage tank.

The safe placement of liquid oxygen tanks is a crucial measure to ensure that the tanks do not pose a 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 storage tanks should maintain a certain distance from other buildings and equipment. This is to ensure effective control and reduction of the impact on the surrounding environment in the event of a tank leak or fire.
Fire and Explosion Prevention Measures: Liquid oxygen tanks should be placed in a fire-resistant area, 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 and foam sprinkler systems, to address potential fire risks.
Stable Placement: Liquid oxygen tanks 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 tilting or rocking.
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 must be clearly marked with information such as the stored medium, capacity, and pressure. Warning signs and safety alerts should be posted 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 storage tanks should be regularly inspected and maintained, including checking the tank's appearance, seal integrity, and corrosion prevention measures. Any issues found should be promptly repaired or replaced to ensure proper operation and safety.
Be mindful that the safety requirements for the placement of liquid oxygen tanks may vary by region and industry. When positioning liquid oxygen tanks, adhere to relevant regulations, standards, and safety protocols, and establish appropriate safety measures based on the specific circumstances. If you are unfamiliar with or have doubts about the safety placement requirements, it is recommended to consult with experts or relevant institutions.

Proper installation of the safety valve on liquid oxygen tanks is a crucial step for ensuring their safe operation. Here are the installation steps for the safety valve on liquid oxygen tanks:
Select the Appropriate Safety Valve: Choose a suitable safety valve based on the design pressure and flow requirements of the liquid oxygen storage tank. Ensure that the rated pressure and flow of the safety valve meet the tank's specifications and comply with relevant safety standards and regulations.
Valve Installation Location: Select a suitable location for installing the safety valve. Typically, the safety valve should be mounted at the top or side of the liquid oxygen tank to allow for timely pressure release in the event of overpressure.
Preparation for Installation Interface: Prepare the corresponding interfaces based on the connection method of the safety valve. This may include welding interfaces, threaded interfaces, or flange interfaces, etc. Ensure the tightness and stability of the interfaces.
Install the safety valve: Mount the safety valve onto the prepared interface. Follow the installation instructions for the safety valve to ensure proper connection and tightness.
Adjustment and Testing: After installation, adjust and test according to the requirements of the safety valve. Ensure the opening and closing pressures of the safety valve meet the design specifications, and conduct a leakage test to ensure its sealing.
Labeling and Documentation: Identify relevant information on the safety valve, such as rated pressure, flow rate, and installation date. Additionally, record the installation details and test results of the safety valve for future reference and maintenance.
When installing the liquid oxygen storage tank safety valve, it is imperative to follow the relevant safety regulations and operational guidelines. If you lack the necessary experience and knowledge, it is recommended to seek assistance and guidance from experts to ensure the correct installation and reliable operation of the safety valve.
