There are no devices or methods capable of modifying he natural weather phenomena to the extent that they can prevent lightning discharges. Lightning flashed to, or nearby, structures (or services connected to these structures) are hazardous to people, to the structures and the structure contents and electrical services installations.

The need for protection, the economic benefits of installing protection measures and the selection of adequate protection measures should be determined in terms of risk management.

The criteria for design, installation and maintenance of lightning protection measures are considered by
• Protection measures to reduce the physical damage and life hazard in the structure.
• Protection measures to reduce failures of electrical and electronic systems installed within the structure.
• Protection measures to reduce physical damage and failures of services connected to the structure.
