The harm of lightning to people cannot be underestimated. It not only endangers our property safety, but also endangers our lives! So lightning protection devices are a conscientious product that has emerged and is indispensable. Due to the different terrains and environments in our country, lightning protection devices should naturally vary in different regions. Below, the editor of flexible graphite grounding zone will introduce the classification of lightning protection levels in special environments:

Due to the inherent flammability, explosiveness, toxicity, and harmfulness of many chemicals in the industry, they are prone to fire and explosion accidents that cause mass casualties and significant property losses. Therefore, the country has always attached great importance to the safe production of hazardous chemicals to ensure the safety of people's lives and property. Every year, governments at all levels conduct safety inspections on the manufacturing, use, storage, and other aspects of hazardous chemicals, and lightning protection is also included as a special content of safety inspections. Buildings that manufacture, use, or store large quantities of explosive materials such as explosives, gunpowder, detonating explosives, and pyrotechnic devices can cause significant damage and personal injury due to explosions caused by electric sparks. Buildings that manufacture, use, or store explosive substances, and where electric sparks are not likely to cause explosions or cause significant damage and personal injury. Classification of fire hazards in the production environment and processes of workshops and equipment that manufacture and use hazardous chemicals; Classification of warehouses storing hazardous chemicals and their fire hazards. Because the production conditions and storage environment of both have the risk of flammability and explosiveness, and their fire hazard levels and classification standards for building lightning protection are also very similar, it is incorrect to include some super high-rise civil and commercial buildings in the scope of Class I lightning protection buildings. Because according to the standard definition, all types of lightning protection buildings are explosive hazardous areas, and super high-rise commercial buildings are not included in the category of lightning protection buildings. The division of explosion hazardous areas should be determined based on the level of release sources and ventilation conditions. When ventilation is good, the level of explosion hazardous areas should be lowered; When the ventilation is poor, the level of the explosion hazard area should be increased. It is expected that the release sources that are released periodically or occasionally during normal operation will not be released under normal operation, and even if released, they will only be occasional short-term release sources. When the ventilation in the explosion hazard area can quickly dilute flammable substances to below 25% of the lower explosive limit, it can be classified as well ventilated. The lightning protection level should be improved in the above environments, and lightning protection measures should be taken. During the construction of lightning protection projects, copper-clad steel grounding rods are undoubtedly the best choice, and their superior performance is fully capable of handling the above environment.

The above is the sharing of the editor of flexible graphite grounding strip. We hope everyone can pay attention to the harm caused by lightning and protect their lives and property safety!
