Knowledge of safe handling of liquid nitrogen

Liquid nitrogen is sufficient to cause severe frostbite after contact with the living tissue.

When handling liquid nitrogen, wear appropriate safety devices to prevent contact with or suction of very cold vapors. Make sure the exposed skin surface is covered, preferably insulated.

Because of its boiling so fast, from the liquid to the gas phase change will soon produce a lot of pressure. Do not close liquid nitrogen in a sealed container, as this will cause an explosion.

Adding a large amount of nitrogen to the air will reduce the relative oxygen content. This can lead to the risk of suffocation. The cold nitrogen is heavier than air, so the danger is close to the ground. Remember to use liquid nitrogen in well-ventilated areas.

Liquid nitrogen cans accumulate oxygen from the air. With the evaporation of nitrogen, organic matter is at risk of severe oxidation.

Note:

Liquid nitrogen storage area The area where the liquid nitrogen is used and stored must be adequately ventilated.

Adequate indicates that the oxygen content is maintained at a concentration of 20.8% during normal storage and storage.

Gas release may occur during liquid nitrogen storage:

Open the unconsolidated container in daily operation

As the liquid nitrogen tank temperature. For non-pressurized containers this occurs naturally through insulation. Pressure vessel in pressure increase valve opening relief build and then reset;

The rupture of the relief valve causes the rupture disc to break the pressure vessel. This will result in the rapid release of gas in a very short period of time.
