Область применения
This standard applies to lightning safety protection for hazardous chemical production and storage enterprises. It is mandatory for facilities handling flammable and explosive materials to mitigate lightning hazards. It does not cover metal oil tankers and barges, which were addressed in the previous version.
Технические требования
The standard specifies general requirements and lightning warning protocols, including the classification of lightning protection zones and basic safety principles. Large oil and gas storage facilities must install lightning warning systems with an early warning time of no less than 10 minutes and an effective alarm rate of at least 80%. It details lightning protection measures for general facilities, covering electrical systems, electronic information instrument systems, and pipelines. Requirements include equipotential bonding, proper grounding, and the installation of surge protective devices (SPD) that comply with referenced standards. Specific area protection requirements are outlined for production device areas, tank farms, hazardous chemical warehouses, loading/unloading areas, and gas stations. The standard emphasizes direct lightning protection, grounding resistance limits, and specific equipotential bonding for floating roof tanks and non-metallic tanks. For inspection and maintenance, lightning protection devices in fire and explosion hazardous areas must be inspected every 6 months, while other areas require annual inspections. Regular and daily checks must cover air-termination systems, down-conductors, and grounding devices.
Методы испытаний
Verification is conducted by reviewing lightning protection engineering design drawings, completion documents, and lightning protection device inspection reports. The rolling sphere method (Appendix A) is used to determine the protection range of air-termination systems. Inspection parameters and testing procedures must comply with GB/T 21431.
