Risk Assessment

In most cases the need for lightning protection is obvious when any of the following apply:

  • Large crowds
  • Service continuity
  • High flash frequency
  • Tall isolated buildings
  • Structures that contain explosives or flammable materials
  • Structures that house irreplaceable heritage materials/exhibits

Risk assessment is a guide that takes into account the effects of lightning on the following factors:

  • Building exposure
  • Type of construction
  • Building occupancy
  • Building contents
  • Lightning stroke consequences

Consequences of lightning strikes:

Private homes Fire, electrical, plumbing and electronic equipment damage
Farms Fire/sparks, power failure to livestock buildings, and step voltage consequence
Public buildings Risk of fire & panic, power failures including alarm systems, loss of life
Businesses/hospitals Risk of fire & panic, power failures including alarm & electronic equipment, egress problems, handicap egress issues, loss of life
Industrial buildings Production loss, loss of electronic/computer equipment
