Understand the Treatment of Liquid Nitrogen Leakage

  Regarding the leakage of liquid nitrogen in large equipment, we should pay attention to the treatment of liquid nitrogen leakage in order to use liquid nitrogen safely and use liquid nitrogen correctly. For those who use liquid nitrogen tanks regularly, this should be something you must learn that when encountering a liquid nitrogen leak, personnel in the contaminated area should be quickly evacuated to the upper wind and isolated, and access is strictly restricted.


  It is recommended that emergency personnel wear self-contained positive pressure breathing apparatus and wear winter clothes. Do not touch the spill directly. Cut off the source of the leak as much as possible. Prevent gas from accumulating in low recesses and explode in case of ignition. Use the exhaust fan to send the leaked air to the open space. The leaking container should be properly disposed of, repaired, and used after inspection.

  Liquid nitrogen diarrhea treatment method

  When the concentration of inhaled nitrogen is not too high, the patient initially feels chest tightness, shortness of breath, weakness and weakness; then there is irritability, extreme excitement, running, screaming, screaming, gait instability, called “nitrogen strontium”, which can enter drowsiness. Or coma. When inhaled at a high concentration, the patient can quickly stun and die due to breathing and heartbeat.

  First, it is necessary to quickly evacuate personnel from the contaminated area to the upper reaches, and set up an isolation area, strictly restrict access, and notify the fire and related units in a timely manner.

  At the same time, emergency personnel wear self-contained positive pressure breathing apparatus, wear winter clothes, and wear cold gloves.

  Also, avoid leaking liquid into the basement or other closed working spaces. If it is unavoidable, notify the relevant department immediately. And don't touch the spill directly. Need to cut off the source of the leak as much as possible

  However, it is possible to use a spray of water to accelerate the evaporation of the liquid, but not to expose the water gun to the liquid. Be sure to prevent the gas from accumulating in the low recesses, and use the exhaust fan to send the leaked air to the open space. Personnel must be prohibited from staying in low-lying or leeward areas.

  After learning the above methods for dealing with leakage and leakage of liquid nitrogen, I believe that you have been able to safely and correctly use liquid nitrogen tanks. When using a liquid nitrogen tank, pay attention to personal safety. The cold damage of the nitrogen storage tank is basically restored to a normal level.
