To prevent the explosion of liquid oxygen tanks, the following measures can be taken:
Regular Inspections and Maintenance: Conduct regular inspections and maintenance of the liquid oxygen tank, including checking the tank's appearance, welds, valves, and fittings, to ensure they are intact and damage-free. Regularly clean the tank to remove any impurities and dirt 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 proper operation.
Temperature Control: Liquid oxygen tanks should be maintained within an appropriate temperature range to prevent excessive heat from causing increased pressure. Ensure the insulation layer of the tank is intact to minimize heat conduction and loss.
Fire Prevention Measures: Liquid oxygen has a high oxygen content and flammability, so strict fire prevention measures must be taken. A fire-resistant buffer zone should be established around the storage tank, with smoking and open flames prohibited. Ensure the storage tank maintains a sufficient fire-resistant distance from 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 pressure increases. Regularly inspect and test the operational status of the pressure relief devices and safety valves to ensure their proper functioning.
Tank Operation Standards: Adhere strictly to the operational specifications and safety requirements for liquid oxygen tanks. Operators must be trained and familiar with the tank's characteristics and operating techniques. Avoid operational errors and violations.
Emergency Preparedness: Establish emergency response plans and conduct drills to address potential accidents. Train operators in emergency response capabilities to ensure timely and effective actions.
