Lightning rods provide a conductive path for lightning to follow, redirecting the electrical current away from the structure and into the ground, thereby reducing the likelihood of it entering the building and causing harm.

By providing a direct path for lightning to discharge, lightning rods help prevent the formation of side flashes, which occur when lightning jumps from a structure to nearby objects or people. This phenomenon can lead to severe injuries or even fatalities. With lightning rods in place, occupants are shielded from these potential dangers, allowing them to stay safe and protected inside the building during a storm.

In addition to protecting occupants, lightning rods also help prevent structural damage. When lightning strikes a building, it can cause fires, explosions, and significant structural damage due to the intense heat and electrical currents. By intercepting the lightning strike and providing a safe path for it to disperse, lightning rods minimize the risk of these destructive consequences, ensuring the safety of the building and its occupants.
