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 storage tanks should maintain a certain distance from other buildings and equipment. This is to ensure effective control and minimize 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.
Level 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 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.
Labeling and Warning: Oxygen liquid storage tanks must be clearly labeled with information such as the stored medium, capacity, and pressure. Warning signs and safety警示 labels should be posted in the surrounding area to alert personnel of the presence and potential hazards of the oxygen liquid storage tank.
Routine Inspections and Maintenance: Liquid oxygen tanks should be regularly inspected and maintained, including checking the tank's appearance, sealing, and anti-corrosion measures. Any issues found should be promptly repaired or the tank replaced to ensure proper operation and safety.
It's important to note that the safety requirements for the placement of liquid oxygen tanks may vary depending on the region and industry. When positioning liquid oxygen tanks, comply with relevant regulations, standards, and safety procedures, and establish appropriate safety measures based on the actual situation. If you're unfamiliar with or have doubts about the safety placement requirements, it's advisable to consult with experts or relevant institutions.

The use of low-temperature liquid storage tanks requires attention to the following matters:
Safe Operation: Operators must undergo training to understand the procedures and safety precautions for handling the tank. Adhere to the correct operational steps to ensure safe operation.
Protective Gear: Operators must wear appropriate protective gear, such as insulated clothing, gloves, etc., to safeguard against injuries from low-temperature liquids.
Leak Protection: Regularly inspect the tanks and related pipelines for seal integrity to prevent leaks of low-temperature liquids. Keep the area around the tanks clean to avoid debris hindering leak detection and handling.
Fire Protection: Low-temperature liquids are highly flammable and fire precautions must be taken. Maintain a fire-free environment around storage tanks, prohibit smoking and open flames. Equip with appropriate fire-fighting equipment to address fire risks.
Pressure Control: Regularly inspect and maintain the pressure control system of the storage tank to ensure the pressure inside is within a safe range. Safety valves and pressure sensors, among other equipment, should operate normally, and abnormal pressure situations should be detected and addressed promptly.
Insulation Protection: Low-temperature liquid storage tanks should be equipped with effective insulation to reduce heat transfer and liquid evaporation. The selection and installation of the insulation should comply with relevant standards and requirements.
Regular Inspections and Maintenance: Conduct regular inspections of the tank's exterior and interior, checking for leaks, corrosion, wear, or other damage. Pay special attention to the tank's interfaces, valves, and pipelines, ensuring they are functioning properly.
Emergency Preparedness: Develop an emergency response plan, including measures for leaks, fires, and other unforeseen incidents. Operators should be familiar with the emergency response plan and equipped with appropriate emergency equipment and fire fighting materials.

The safety distance for liquid oxygen storage tanks refers to the required distance around the tank to ensure the safety of personnel and equipment. Specific safety distance requirements may vary depending on different regions and application sites. Here are some common safety distance principles: Buildings and equipment: Liquid oxygen tanks should maintain a certain safety distance from buildings, equipment, and other storage tanks to prevent the spread of fires, explosions, and leaks. The specific safety distance requirements should be assessed and determined according to local regulations and standards. Ignition and heat sources: Liquid oxygen is highly oxidizing and can easily cause fires and explosions. Therefore, liquid oxygen tanks should be kept at a sufficient distance from ignition sources, heat sources, and flammable materials to prevent fires and explosions. Ventilation and exhaust: Good ventilation and exhaust should be maintained around liquid oxygen storage tanks to prevent the accumulation of evaporated oxygen and the formation of explosive mixtures. The design and operation of the ventilation and exhaust system should comply with relevant safety standards and specifications. Personnel and traffic: Personnel and traffic around liquid oxygen storage tanks should be restricted and controlled to ensure personnel safety and the normal operation of the tank. Warning signs, safety fences, and restricted areas should be established to prevent unauthorized access to the tank area. It should be noted that the safety distance for liquid oxygen storage tanks should be assessed and determined based on the specific application site and safety requirements. When designing, installing, and operating liquid oxygen storage tanks, relevant regulations, standards, and safety guidelines should be followed to ensure the safety and reliability of the tank.

Proper management regulations for the use of low-temperature liquid storage tanks include the following aspects:
Tank Selection and Installation: Choose an appropriate low-temperature liquid storage tank and ensure it complies with relevant standards and regulations. The installation of the tank should be carried out by personnel and operated according to the manufacturer's instructions and requirements to ensure stability and safety.
Safety Operating Procedures: Establish and implement safety operating procedures for liquid storage tanks, including start-up, shutdown, filling, venting, and other operational steps. Operators must receive training to understand the characteristics of liquid storage tanks, safety precautions, and emergency response measures.
Safety Equipment and Protective Measures: Tanks should be equipped with necessary safety devices, such as pressure sensors, safety valves, leak detectors, etc., to monitor and control the pressure and temperature of the tank. At the same time, operators should wear appropriate personal protective equipment, such as insulating gloves, protective suits, etc., to ensure their own safety.
Regular Inspections and Maintenance: Conduct regular inspections and maintenance on low-temperature liquid storage tanks, including checking the tank's appearance, sealing, and corrosion prevention measures. In case of any issues, promptly repair or replace the tank to ensure its proper operation and safety.
Waste Management: Abandoned low-temperature liquid storage tanks must be disposed of in accordance with relevant environmental protection regulations. The residual liquid in abandoned storage tanks should be properly handled to prevent environmental pollution.
Tank Record and Tracking: Establish tank usage records, including filling dates, filling quantities, usage status, etc. Additionally, it is recommended to set up a tank tracking system for monitoring and managing the usage and maintenance of the tanks.
The above outlines some common regulations for the management of low-temperature liquid storage tanks. Specific regulations may vary by industry and region. When using low-temperature liquid storage tanks, relevant laws and standards should be adhered to, and appropriate management measures should be established based on the actual situation.
