Lightning protection protects a building by providing a safe path for lightning to follow, reducing the risk of damage or fire. A lightning protection system typically includes: 1. Air terminals (lightning rods): Attract lightning and direct it to the down conductor. 2. Down conductors: Carry the lightning current from the air terminal to the ground electrode. 3. Ground electrodes: Dissipate the lightning current harmlessly into the earth. 4. Surge protectors: Protect electrical systems and appliances from power surges. 5. Bonding: Connect metal parts to prevent side flashes and ensure a safe path to ground. This system: 1. Reduces the risk of fire and explosion. 2. Protects electrical systems and appliances from damage. 3. Minimizes structural damage to the building. 4. Ensures continuity of critical operations. 5. Safeguards people and assets within the building. It's important to note that lightning protection systems should be installed and maintained in accordance with local standards and regulations, such as the National Electric Code (NEC) or the International Electrotechnical Commission (IEC) standards.
