Procedure (for each risk) to calculate the need of protection

  • Identify the risk components (Rx) which make up the risk
  • Calculate the identified risk components (Rx)
  • Calculate total risk (R)
  • Identify the tolerable risk (RT)
  • Comparison of the risk R with the tolerable value (RT)
  • If R < RT, lightning protection is not necessary
  • If R > RT, protection measure shall be adopted in order to reduce R
