To prevent hazards 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 discharges 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.
Anti-static Equipment: Utilize anti-static 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.
Electrostatic Discharger: Utilize an electrostatic discharger to neutralize static electricity. It does so by releasing opposite charges, thereby reducing static buildup and spark generation.
Electrostatic Safety Training: Conduct electrostatic safety training for personnel using liquid oxygen tanks to enhance their understanding and awareness of electrostatic hazards. The training content can include the principles of electrostatic formation, preventive measures, and emergency response procedures.
It is important to note that the static electricity prevention measures for liquid oxygen tanks should be designed and implemented by personnel, following relevant safety operation procedures and standards. During operation, strict adherence to the prescribed operational procedures is required to avoid the generation of static sparks and ensure the safety of the tank.

Proper placement of liquid oxygen tanks is a crucial measure to ensure that the tanks pose no danger to the surrounding environment or 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 for safety reasons. This is to ensure effective control and reduction of the impact on the surrounding environment in case of leaks or fires.
Fire and Explosion Prevention Measures: Liquid oxygen tanks should be located 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: 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 could impede gas flow.
Identification and Warning: Liquid oxygen tanks should be clearly marked with information such as the storage 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 liquid oxygen 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 can vary depending on the 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 situation. If you're unfamiliar with or have doubts about the safety placement requirements, it's advisable to seek guidance from experts or relevant institutions.

Proper installation of the liquid oxygen tank 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 tank safety valve:

Valve Installation Location: Select a suitable location for installing the safety valve. Typically, the safety valve should be mounted on the top or side of the liquid oxygen storage tank to ensure timely pressure release in the event of overpressure.
Prepare installation interfaces: 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 firmness of the connections.
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 tightening.
Adjustment and Testing: After installation, adjust and test according to the safety valve specifications. Ensure that the opening and closing pressures of the safety valve meet the design requirements and conduct a leakage test to verify its sealing integrity.
Identification and Record: Label the safety valve with relevant information 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 operation guidelines. If you lack the necessary experience and knowledge, it is advisable to seek assistance and guidance from experts to ensure the correct installation and reliable operation of the safety valve.
