- Always switch off and unplug electrical appliances during a storm.
- Install lightning surge protectors at all plug points, especially where you have expensive and important equipment plugged in. This is not only to protect the equipment, but also any person who may be using the equipment at the time of a lightning strike or power surge.
- Install a heavy-duty surge suppressor at your main electricity distribution board. These surge suppressors are designed to deal with large voltages as they enter your building, minimising the impact on your equipment. Make sure that only a licensed electrician installs this and schedule an annual inspection for extra safety. Modems and computers are some of the first items that are normally damaged in a surge.
- Where required, install a lightning conductor in the form of a free-standing mast for thatch roofs. These must be SABS approved and installed by a qualified person. The combustible properties of thatch in areas with high lightning density pose serious fire hazards.
- Make sure all your gutters are clean and free of debris or blockages so they can allow for maximum drainage during a heavy downpour.
- Inspect your roof each year for leaks and damage to prevent water damage to ceilings.
- Inspect any surrounding trees and remove any dead branches which could cause damage if they fell on your property, vehicle or even worse, a person.
- The addition of lightning surge protectors to your intercom system, alarm system and gate motor should not be overlooked as these items are susceptible to lightning damage. Also check your insurance policy to confirm what the outcome would be if your burglar alarm was damaged, without your knowledge, and you were burgled.
