Lightning attachment to buildings can significantly affect structural safety. Here are some key impacts:

1. Structural Damage: Lightning strikes can cause direct structural damage. The intense heat and electrical energy can crack or even shatter building materials such as concrete, stone, and brick. This can compromise the integrity of the structure.

2. Fire Hazards: One of the primary risks of a lightning strike is fire. The high temperatures produced by a strike can ignite building materials, leading to fires that threaten the entire structure.

3. Electrical System Impact: Lightning can induce voltage surges that damage electrical systems, appliances, and safety equipment within buildings. This can disrupt the operation of critical safety systems like elevators and fire alarms.

4. Overvoltage and Current Surge: Lightning current and accompanying overvoltages in lines can impact various safety equipment. These surges can travel through wiring and pipelines, impacting systems far from the point of the strike.

5. Protective Measures: Proper lightning protection systems (LPS) are essential. These systems are designed to safely direct the lightning current to the ground, minimizing potential damage and improving safety.
