Lightning strikes pose a significant fire risk to buildings, structures, and natural areas, capable of igniting devastating fires within seconds. Lightning protection systems (LPS) play a crucial role in mitigating these risks by safely dissipating the electrical energy of a strike. This article examines the importance of lightning protection in fire prevention, detailing how these systems work and their benefits in safeguarding against lightning-induced fires.

Fundamentals of Lightning-Induced Fires
Lightning strikes can generate intense heat and electrical currents capable of igniting combustible materials in buildings, trees, and other structures. The risk of fire is particularly high when lightning directly strikes a structure or when surges induced by a strike affect internal wiring and equipment.
Mechanism of Ignition
The mechanism of ignition in lightning-induced fires involves the intense heat generated by the electrical discharge, which can exceed 20,000°C, instantly vaporizing water in wood and...
