To prevent the explosion of liquid oxygen tanks, the following measures can be taken:
Regular inspections and maintenance: Conduct regular checks and maintenance on liquid oxygen tanks, including inspecting the tank's appearance, welds, valves, and fittings, to ensure they are intact and undamaged. Regularly clean the tank to remove any dirt and impurities adhering to its surface.
Pressure Control: Storage tanks should be equipped with pressure control devices to ensure the internal pressure of the tank remains within a safe range. Regularly inspect and adjust the pressure control devices to ensure their proper functioning.
Temperature Control: The liquid oxygen tank should be maintained within an appropriate temperature range to prevent excessive heat from causing increased pressure. Ensure the tank's insulation is intact to minimize heat transfer and loss.
Fire Prevention Measures: Liquid oxygen has a high oxygen content and flammability, hence stringent fire prevention measures are required. A fire isolation zone should be established around the storage tank, and smoking and open flames are prohibited. Ensure a sufficient fire separation distance between the storage tank and other facilities.
Pressure relief devices and safety valves: Liquid oxygen storage tanks should be equipped with pressure relief devices and safety valves to prevent overpressure and sudden increases in pressure. Regularly inspect and test the operational status of the pressure relief devices and safety valves to ensure proper functioning.
Tank Operation Standards: Adhere strictly to the operation standards and safety requirements for liquid oxygen tanks. Operators must be trained and familiar with the tank's characteristics and operation techniques. Avoid operational errors and violations.
Emergency Preparedness: Establish emergency response plans and conduct drills to handle potential accidents. Train operators on emergency response capabilities to ensure timely and effective responses.

When using a 50-cubic-liter liquid oxygen tank, the following safety concerns should be noted:
Tank Pressure Control: Ensure that the liquid oxygen pressure within the tank remains within a safe range. Monitor and control the tank's pressure to avoid risks posed by either excessive or insufficient pressure.
Leakage and Fire Prevention: Regularly inspect the tank and associated pipelines for sealing integrity to prevent liquid oxygen leakage. Liquid oxygen is highly flammable and fire prevention measures must be taken to ensure there are no ignition sources around the tank.
Explosion Prevention Measures: Oxygen inside the liquid oxygen tank may cause an explosion upon contact with flammable materials. Ensure there are no flammable items around the tank and implement explosion prevention measures, such as explosion-proof electrical equipment and static grounding.
Safety valves and exhaust systems: Tanks should be equipped with safety valves and exhaust systems to prevent overpressure situations. Ensure the proper operation of the safety valves and the unobstructed flow of the exhaust system.
Routine Maintenance and Inspection: Conduct regular maintenance and inspections of the storage tanks, including cleaning, coating protection, and anti-corrosion treatments. Ensure the structural integrity and safety of the tanks.
Safety Operation and Training: Operators must undergo relevant safety training to understand the safety operation procedures and emergency response measures for liquid oxygen storage tanks. Adhere to the correct operational steps to ensure safe operation.
Environmental Monitoring: Regularly monitor environmental parameters such as oxygen concentration and temperature around the storage tanks to ensure safety.
Emergency Preparedness: Develop an emergency response plan, including measures for leaks, fires, and explosions. Equip with appropriate emergency and fire-fighting equipment to handle unexpected incidents.
Above are some safety issues to be aware of when using a 50-cubic-liter liquid oxygen storage tank. To ensure safety, it is recommended to follow relevant safety regulations and operation guidelines, and seek assistance and guidance from experts when necessary.

To prevent the dangers associated with liquid oxygen tanks, the following precautions can be taken:
Safety Operations and Management: Establish and enforce stringent safety operations and management systems, including proper use of storage tanks, operational procedures, and safety training. Ensure operators possess the necessary safety awareness and skills, adhere to operational procedures, and minimize operational errors and the likelihood of accidents.
Regular inspections and maintenance: Conduct regular checks and maintenance on liquid oxygen tanks, including visual inspections, pressure tests, and leak detection. Promptly identify and address any issues with the tanks to ensure their safety and reliability.
Safety devices and protective equipment: Tanks should be equipped with necessary safety devices, such as pressure relief valves, liquid level alarms, etc., as well as protective equipment like fire barriers and explosion-proof devices. These devices and equipment can take timely action in abnormal situations to ensure the safety of the tank.
Fire Prevention Measures: Liquid oxygen contains a high concentration of oxygen, which is highly flammable. As such, fire prevention measures such as firewalls and fire extinguishers should be installed around the storage tank to prevent the spread and escalation of fires.
Leakage Control and Emergency Response Plan: Establish a liquid oxygen tank leakage control and emergency response plan, including leakage control measures, emergency response procedures, and evacuation plans. In the event of a leakage incident, the plan allows for prompt action to control the leak and ensure personnel safety.
Training and Awareness Enhancement: Conduct regular safety training for liquid oxygen cylinder users to enhance their safety awareness and emergency response capabilities. Strengthen safety

The reasons why low-temperature liquid storage tanks have been at the peak in recent years are as follows:
Rising Demand: As industries and scientific research sectors develop, there is a growing demand for low-temperature liquids. Low-temperature liquid storage tanks can effectively store and supply liquid oxygen, liquid nitrogen, liquid gases, and other low-temperature liquids, meeting the needs of various fields.
