Lightning Protection Risk Assessment

Lightning Protection Risk Assessment


A Lightning Protection Risk Assessment is the measure of risk of a lightning strike and probability of damages. It assesses the lightening risks to the facility according to international standards.

Lightning Protection International are specialist experts in Lightning Protection Risk Assessments and our Lightning Protection Consultants can conduct the assessment for you and provide Lightning Protection System Design if required.

All of our Lightning Protection Risk Assessments are according to IEC Standard 62305-2.

What is included in a Lightning Protection Risk Assessment:

There are eight parts to a Lightning Protection Risk Assessment. These are as follows

  1. Lightning Strike Density. This is the measure of lightning strikes per kilometre per year in that particular area. The higher the lightning strike density rate, the higher the probability of a lightning strike.
  2. Danger for People. This is the factor of presence of people and people in the building in the event of a lightning strike.
  3. Occupancy Coefficient. This is the risk reduction factor with respect to the use / occupancy of the building. For example, the loss due to a lightning strike is higher in a data centre as compared to a warehouse.
  4. Relative Location of Site. This is the risk reduction factor with respect to the the location and the surroundings of the building / site. For example, the chance of a lightning strike is reduced if the building is close to a high tower.
  5. Fire Risk. The risk reduction factor with respect to the flammability of the material present in the building / installation. For example, the risk of fire damage is far greater with petroleum storage than with cement storage.
  6. Associated Services. The risk reduction factor with respect to the services associated with the building. For
    example, a lightning strike at a power station will result in a power break down which increases the loss and disturbance.
  7. Electrical Lines. Presence of electrical lines increases the chance of a lightning strike. For example, if lightning
    strike on the overhead line, the line will transport this to the building / installation.
  8. Lightning Protection Level. Lightning protection level defines the kilo ampere rating of the lightning protection system,
    minimum distance between the lightning arrestors and density of the protective mesh.
  9. Surge Arrestors. These are the Surge Protection Devices which blocks the surge from entering the installation
    premises. Normally installed at the incomer supply (main distribution box). These are used if
    the system is connected with over head lines.
  10. Tolerable Risks. As part of a Lightning Protection Risk Assessment, risk to human life, services and
    cultural heritage will be obtained in figures which must be lesser than tolerable risk (specified in
    codes and standards). The outcome of the study will then be used as a guide to select the
    level of Lightning Protection System Design to contain the risk with in tolerable limits.
