1、 liquid oxygen storage tank equipment place should have good ventilation, generally appropriate equipment in outdoor, surrounded by a fence, 5m within no open fire, combustible and explosive materials and low-lying places;
2、 liquid oxygen storage tank is necessary to have the grounding equipment and lightning protection equipment to conduct static electricity. Anti-static grounding resistance of not more than 10Ω; lightning protection equipment Z large impact resistance of 30Ω, and at least once a year to test;
3、 liquid oxygen storage tank filling rate shall not be greater than 95%, prohibit overfilling;
4、 pressure gauge prohibit oil, and regularly calibrated; safety valve is necessary stainless steel or copper, regularly calibrated, and severely de-oiled;
5、 when the equipment on the valve, exterior, piping and other frozen, the application of 70 ~ 80 ℃ nitrogen, air or hot water thawing, prohibit open fire heating;
6、 liquid oxygen storage tanks with liquid, prohibit fire repair, it is necessary to warm up to room temperature before repair;
7、 The operator should be trained and qualified by the examination before taking up the job. Shall not wear chemical fiber clothing with oil or electrostatic effect, and shall not wear shoes with nails. The valve should be opened and closed slowly during operation. The booster valve to be closed tightly when decommissioned;
8、 Regularly (e.g. 15 days) dissect the acetylene concentration in liquid oxygen, and its concentration is manipulated below 0.1×10-6, otherwise liquid oxygen should be discharged;
9、 When liquid oxygen is stored in closed storage, it is necessary to have someone to monitor the pressure and not to overpressure;
10、 liquid oxygen is not allowed to splash on unprotected skin to avoid producing grim;
11、 When the liquid oxygen storage tank has been emptied of liquid and cannot be heated immediately, it is necessary to close all the valves immediately. Because the temperature inside the tank is very low, the wet air will invade inside through the connected pipes and form the accident of icing blocking the pipes.
