Assessing Your Risk

No one can predict when and where lightning will strike. The National Fire Protection Association’s (NFPA) Risk Assessment is the only tool used by the lightning protection industry to determine the risk of a lightning strike. To assess your risk, answer the following questions. Based on your answers, this assessment will evaluate how individual factors, of your structure and its location, affect your need for lightning protection.
