This article analyzes the hazardous characteristics of low-temperature liquids and, in conjunction with various gas supply modes for low-temperature storage tanks, briefly outlines their basic requirements and key safety usage points.

An LNG storage tank is a jacketed vacuum powder-insulated pressure vessel specifically designed for storing and supplying low-temperature liquefied gases (such as liquid nitrogen, liquid oxygen, liquid argon, liquid carbon dioxide, etc.). It has been widely used in both industrial production and daily life.

1. Analysis of Low-Temperature Liquid Hazardous Characteristics

Low-temperature liquids possess hazardous characteristics such as low boiling points, high expansibility, strong asphyxiating properties, and strong oxidizing properties.

1.1 Boiling points of low-temperature liquids under 101.3 KPa pressure: Liquid nitrogen at -196°C, liquid oxygen at -183°C, and liquid argon at -186°C. Contact with the human body can cause severe frostbite to the skin and eyes. In cases of minor leakage or internal leakage in valves, they absorb heat from the surrounding environment, causing rapid condensation and frost formation at the leakage point, which can lead to freezing in severe cases.

1.2 Low-temperature liquids absorb energy from the surrounding environment due to high heat or large leaks, causing their volume to expand as they rapidly vaporize. Under 0°C and 101.3 KPa pressure, the volume of gases resulting from the vaporization of 1L of low-temperature liquid is: nitrogen at 674L, oxygen at 800L, and argon at 780L. Inside sealed containers or pipelines, the increase in internal pressure due to the vaporization of low-temperature liquids can easily lead to overpressure explosions.

1.3 In the surrounding environment of low-temperature storage tanks, low-temperature liquid leakage upon vaporization is prone to create enriched gas areas. High concentrations of nitrogen, argon, and carbon dioxide can easily cause asphyxiation injuries. Additionally, elevated oxygen concentrations can lead to enriched oxygen injuries.

1.4 Oxygen is a powerful oxidizing agent with extremely strong oxidizing properties. Liquid oxygen, when in close proximity to combustible materials, can easily ignite upon contact with an open flame; contact with combustible materials can cause explosions due to vibrations or impacts; a mixture with combustible materials poses a potential explosive hazard. Liquid oxygen can adhere to clothing and fabrics, and upon contact with an ignition source, it can cause a flash fire, potentially harming individuals.
