The nitrogen contained in a general nitrogen cylinder. Large storage tanks are generally liquid.
1. The state of nitrogen in the cylinder is different.
The state of nitrogen in the cylinder, the liquid nitrogen cylinder is naturally liquid (of course there will be some vaporization), while the gaseous state of high-pressure nitrogen.
2. Different pressures.
The pressure difference. The pressure of the high-pressure nitrogen cylinder is much higher than that of the liquid nitrogen cylinder.
Liquid nitrogen storage protection
Operation precautions: airtight operation. Airtight operation provides good natural ventilation conditions. Operators must undergo special training and strictly abide by the operating procedures. It is recommended that operators wear cold-proof clothing and gloves. Prevent gas from leaking into the workplace air. Lightly load and unload during transportation to prevent damage to cylinders and accessories. Equipped with leakage emergency treatment equipment.
Storage precautions: Store in a cool, ventilated warehouse. The storage temperature should not exceed 30°C. The storage area should be equipped with leakage emergency treatment equipment.
Engineering control: airtight operation, providing good natural ventilation conditions.
Respiratory protection: Generally, no special protection is needed. However, when the oxygen concentration in the air in the workplace is lower than 18%, an air respirator, oxygen respirator or long tube mask must be worn.
Eye protection: wear a safety mask.
Body protection: wear cold-proof clothing.
Hand protection: wear cold-proof gloves.
Other protection: avoid high concentration inhalation. Prevent frostbite.
