Aim of the risk management

The risk assessment contains:

  • the determination of the necessity of lightning protection
  • the definition of technical and economic protection measures in a optimal way
  • the concluding determination of a remaining risk


  • First to define the distribution of the protected object into several lightning protection zones (LPZ), the geometrical boundaries, relevant characteristic data, lightning threat data and considered types of damage.
  • Based on it, the remaining risk is reduced by application (of further) protection measures until it falls below the value of an acceptable risk
