Lightning safety tips

South Africa has one of the highest lightning ground strike densities in the world, and every year in summer rainfall areas lives are lost to this underrated natural hazard. But lightening also strikes in winter. Here's what you need to know

Lightning is perhaps the foremost underrated natural hazard. Thunderstorms occur ofttimes over giant components of Republic of South Africa, particularly in summer within the north and through winter within the south, and death and injury from lightning strikes aren't uncommon.

What are you able to do to guard yourself? Get inside

 You don't need to be outside in AN violent storm. continually check the prognosis before designing any out of doors activity.

If you're outside once the storm approaches, get into a building, or failing that, a vehicle, as before long as potential.

Don’t hesitate and surprise once to create a move. If you see lightning, hear thunder or perhaps see dark storm clouds overhead, that’s the time to induce inside. Some weather consultants advocate the subsequent test: if the time between a lightning flash and corresponding thunder clap is a smaller amount than thirty seconds, the storm is hazardously shut.

But rather don’t stand around investigation – get within.

The best place to be throughout a electric storm is within a proper structure with solid walls and roof – tents can supply no protection, and automobile ports, open garages, coated patios, sheds and greenhouses are not comfortable either.

It's smart if the building additionally has correct plumbing and electricity: if lightning strikes directly, the electrical current can usually travel through the wiring and/or plumbing, then into the bottom.

This is why you must avoid something within the building connected to the utility (e.g. sinks, baths) or electrical system (e.g. plug sockets, twilled telephones, electrical appliances).

Any metal conductor exposed to the skin might become a lightning passage and thus should not be touched.

Don't watch lightning from open windows or doorways. keep within till a minimum of half-hour when the last clap of thunder.

Vehicles and lightning

If there isn't any safe building to require shelter in, best choice is an internal, metal-sided and metal-roofed vehicle. (Open vehicles sort of a convertible or the rear of a bakkie, and cars with fiberglass or plastic shells, will not give comfortable protection.) Once within, like a building, avoid contact with conductors to the skin.

Close the windows, lean faraway from the door, and do not bit the wheel, ignition, gear stick or radio. If you’re driving once a electric storm hits, stop and guide if you'll, or a minimum of weigh down. keep within the vehicle and observe the 30-minute rule.

When you can’t get inside

If you get caught outside, take action to cut back the danger of being struck: Lightning tends to strike the best object within the space, therefore keep one's distance from isolated trees and phonephone poles. A high share of lightning fatalities area unit caused by folks making an attempt to shelter from the storm beneath a tree. If you’re in an exceedingly forest, keep close to a lower stand of trees. Avoid wide-open exposed areas, hilltops and rocky outcrops; get all the way down to a lower elevation if you'll.

Remember, a tent offers no protection from lighting. keep one's distance from water, wet things and metal objects like wire fences, as these area unit glorious conductors of electricity. build yourself the tiniest, lowest potential target. this can be best done by forward the “lightning position”: squat together with your feet along, put away your head and canopy your ears.

Don't huddle in an exceedingly cluster – keep a handful of body lengths between folks. That way, if one person gets hit, there's a less probability of the charge spreading to the others.

When somebody is smitten by lightning

Call for emergency medical facilitate. Being smitten by lightning will have a devastating impact on the body, as well as major burns, system injury, loss of hearing and visual modality, and broken bones.

Do cardiopulmonary resuscitation if the person has stopped respiration.

Unlike somebody electrocuted by a nonstop current, somebody UN agency has been smitten by lightning carries no electrical charge and might be touched.

The best place to be in an exceedingly electric storm is in an exceedingly solid, properly-earthed building. Flimsy structures like tents supply no protection.

When indoors:

Don't use any instrumentation that is directly connected to electrical phenomenon or fed from the skin, like computers, televisions or twilled telephones.

Stay away from plumbing, like taps, sinks and bathtubs.

Don't hang around on the stoop. return within and keep one's distance from doors and windows.

Don't rest on a concrete wall or lie on a concrete floor.

The best choice may be a stationary vehicle with metal sides and roof (the metal shell shaped by the automobile helps deflect the electrical charge). shut the windows; lean faraway from the door; do not bit the wheel, ignition, mechanical device or radio. keep within the vehicle a minimum of half-hour when the last thunder-clap.

If you are caught outside in an exceedingly electric storm removed from befittingly protecting buildings or vehicles, avoid the following:

High, exposed areas

Tall, isolated structures like trees and phonephone poles

Metal structures like fences

Water.

If the lightning's right overhead, assume the "lightning position / crouch": squat with feet along, head tucked in, ears coated. do not huddle in an exceedingly cluster – unfolded.
