Poisoning treatment


  1, first aid measures


   Skin contact: If frostbite occurs, seek medical attention.


   Inhalation: quickly leave the scene to a place with fresh air. Keep the airway unobstructed. If breathing is difficult, give oxygen. If breathing stops, give artificial respiration immediately. Seek medical attention.


  2, fire-fighting measures


  Hazard characteristics: In case of high heat, the internal pressure of the container will increase, and there will be a risk of cracking and explosion.

Fire fighting method: This product is non-flammable. Use water mist to keep the containers in the fire area cool. Water spray can be used to accelerate the evaporation of liquid nitrogen, but the water gun can not be shot to liquid nitrogen.


  3, emergency treatment


  Emergency treatment: quickly evacuate personnel from the leaked contaminated area to the upper wind, and isolate them, strictly restrict access. It is recommended that emergency personnel wear self-contained positive pressure breathing apparatus and wear cold-proof clothing. Do not directly touch the leakage. Cut off the source of leakage as much as possible. Use the exhaust fan to send the leaked air to the open area. Leaking containers should be properly handled and used after repair and inspection.
