eFlux Electrical CC

Fully Registered & Accredited Electrical Contractor


Normal Electrical Certificates of Compliance

Lightning Pole, LPS, ATS, Electric Fence - Certification & Testing

eFlux has been manufacturing, testing, certifying, installing and maintaining Lightning Protection Systems (LPS) and Air Termination Systems (ATS) fince 2005. Contact us now, to find out how we could solve some of your problems. In order to keep persons and property safe from any kind of electrical shock or current leakage, discharging through a person, losing life or property - One needs to be sure that any and all electrical systems, have been installed, tested and free of these mishaps - the only way, is to stick to a set standard. The internationally accepted standards are SANS 10142:1 - Code for the wiring of premises, SANS 63205, SANS 10313:2010 among others. We test, and issue valid certificates for normal COC testing of houses, factories and plants. We also do certification testing on Electric fences and lightning deterrant systems.

June 18, 1999: Either lightning is attracted to     testosterone, or men spend an inordinate amount of time outdoors     swinging metal objects about. Men are struck by lightning four     times more often than women.     

According to a study entitled "Demographics of U.S. Lightning     Casualties and Damages from 1959 - 1994," by Ronald L. Holle     and Raúl E. López of the National Severe Storms     Laboratory and E. Brian Curran of the National Weather Service,     males account for 84% of lightning fatalities and 82% of injuries.

Men can take comfort in the fact that the actual number of deaths and injuries from lightning strikes has decreased in the past 35 years. Holle's team attributes 30 percent of the decrease in lightning deaths to improved forecasts and warnings, better lightning awareness, more substantial buildings, and socioeconomic changes. They attribute an additional 40 percent to improved medical care and communications.

The National Weather Service publication Storm Data, recorded 3,239 deaths and 9,818 injuries from lightning strikes between 1959 and 1994. Only flash floods and river floods cause more weather-related deaths. But according to Dr. Elisabeth Gourbière of the Electricité de France, Service des Etudes Médicales, only 20 percent of lightning victims     are immediately struck dead. Still, many doctors do not fully understand how to treat the injuries of the other 80 percent of lightning victims who survive a strike.

Most doctors are more familiar with electrical shocks, such as those received by industrial workers when they have an accidental run-in with high-voltage equipment. But lightning injuries are not the same as electrical shocks. For one thing, the contact voltage of a typical industrial electrical shock is 20 to 63 kilovolts, while a lightning strike delivers about 300 kilovolts.

Industrial shocks rarely last longer than half a second (500 milliseconds) because a circuit breaker opens or the person is thrown far from the live conductor. Lightning strikes have an even shorter duration, only lasting up to a few milliseconds. Most of the current from a lightning strike passes over the surface of the body in a process called "external flashover."

Both industrial shocks and lightning strikes result in deep burns at point of contact - for industry the points of contact are usually on the upper limbs, hands and wrists, while for lightning they are mostly on the head, neck and shoulders. Industrial shock victims sometimes exhibit deep tissue destruction along the entire current path, while lightning victims’ burns seem to center at the entry and exit points. Both industrial shock and lightning victims may be injured from falling down or being thrown, and the leading cause of immediate death for both is cardiac or cardiopulmonary arrest.

If you survive a shock, you still have to deal with the consequences of the electrical burns. Industrial shock burns can lead to kidney failure, infection, muscle and tissue damage, or amputation.   Lightning burns are exceptionally life threatening (see box at the end of this story).

Right: High voltage electrical equipment can cause severe shocks and burns slightly similar to those from lightning strikes.

Gourbière says that 70 percent of lightning survivors experience residual effects, most commonly affecting the brain (neuropsychiatric, vision and hearing). These effects can develop slowly, only becoming apparent much later.
