Lightning protection and grounding requirements for liquid nitrogen storage tanks are as follows:
1. The liquid nitrogen storage tank itself must have a good grounding device to ensure that the resistance between it and the ground is less than 10 ohm, thus effectively discharging static electricity and lightning to the ground.
2. The environment around the liquid nitrogen storage tank must also have good grounding devices, including buildings, equipment and pipelines around the storage tank, to ensure that the grounding resistance of the whole area is less than 10 ohm.
3. The grounding device of liquid nitrogen storage tank must be inspected and maintained regularly to ensure its normal operation. If it is found that the grounding resistance is too large or the grounding device is damaged, it must be repaired or replaced in time.
4. Under lightning weather conditions, additional lightning protection measures must be taken for liquid nitrogen storage tanks, such as installing lightning rods and lightning protection nets, to protect the safety of storage tanks and surrounding equipment.
5. Operators of liquid nitrogen storage tanks must undergo professional training and assessment, understand the safety operation procedures and lightning protection measures of liquid nitrogen storage tanks, and ensure that no safety accidents occur during operation.
In a word, the lightning protection and grounding of liquid nitrogen storage tank is an important guarantee for the safe operation of liquid nitrogen storage tank, and the relevant safety regulations and operating procedures must be strictly observed to ensure the safety of liquid nitrogen storage tank and surrounding equipment.
