1.Adjust the flow rate during liquid oxygen filling operations. The static electricity generated by liquid oxygen flowing through pipelines is proportional to the square of the flow rate. Reducing the flow rate is an effective method to minimize static electricity generation.
2.Prevent destructive splash charging: Splashing from the top of the tank generates twice the static electricity compared to bottom-entry filling. If top-entry filling is used, the feed pipe must be inserted to the tank bottom.
3.Eliminate body static electricity: Personnel entering hazardous areas must wear anti-static shoes, anti-static clothing, or cotton knit work uniforms. Install body static discharge equipment at the liquid oxygen tank elevator access point.
4.Prevent static accumulation; grounding systems form the fundamental and critical defense against static electricity. Metal jumpers must connect adjacent small metal components, flanges, or tees with insulated gaskets. Regularly maintain the resistance of liquid oxygen tank grounding connections to ensure the grounding system remains continuously effective.
