Cryogenic storage tank, cryogenic gas cylinder leakage treatment method

1、Immediately stop the supply of liquid oxygen, liquid nitrogen, open the blowing and drainage and immediately notify dispatch of the need for fire and rescue personnel to enter the scene of the accident;

2, circle the scene, prohibit extraneous personnel from entering the accident area, set up a cordon area to prevent personnel from entering by mistake; prevent static electricity, sources of ignition, etc. and immediately remove flammable substances around, do not absorb with sawdust or other combustible absorbents, do not spray water directly onto the liquid. liquid nitrogen leakage using oxygen alarm meter continuous testing to avoid asphyxiation, ventilation should be maintained, do not spray water directly on the liquid;

   3. prevent frostbite accidents by wearing protective equipment, including self-contained breathing apparatus; in the event of frostbite, wash immediately with plenty of water, do not remove clothing and treat promptly;

4, use sandbags to block the flow of liquid to the danger area;

5、Personnel injuries should be contacted with the hospital or emergency center (120); the situation is serious enough to endanger the safety of personnel should be evacuated;

6, adjust the production load of the device as far as possible without affecting the operation of the device, start the gasifier as soon as possible to exhaust the liquid oxygen liquid nitrogen in the storage tank;

7, heating replacement of cryogenic storage tank system, overhaul leak points;

Cryogenic storage tank, cryogenic gas cylinder leak prevention measures

1, every hour of every shift on the liquid cryogenic storage tank system for careful inspection, check the external frost of the cryogenic storage tank, external leakage and sealing gas supply, etc., to find problems in a timely manner;

2, low-temperature storage tank safety valve to be regularly inspected, back in time to install;

3, cryogenic storage tank filling can not exceed 95% of the liquid level.
