Safety tips during a lightning storm

[Henry Tenby]

WHAT YOU SHOULD KNOW:

Lightning is attracted to tall, isolated objects like trees.

Metal does not attract lightning, but is a prime conductor, as is water.

Two-thirds of all lightning strikes occur in June, July and August; most occur in the afternoon.

The average lightning flash packs enough power to light a 100-watt light bulb for more than three months.

A large proportion of lightning deaths occur in, on or near open water. Many people also die sheltering under trees. Nowhere outside is safe from lightning.

WHAT YOU SHOULD DO:

Heed the warning: "When thunder roars, go indoors!"

Take shelter in a substantial building or fully enclosed, metal-topped vehicle. Avoid small structures such as beach cabanas or tents.

When inside your home or other building, avoid using a corded telephone, except for emergencies. Cordless phones are safe.

Avoid electrical appliances and plumbing. Don't wash dishes or take a bath or shower.

Practise the 30-30 Rule: When you see lightning, count until you hear thunder. If it's 30 seconds or less, the storm is within 10 kilometres and dangerous. Seek immediate shelter. Wait 30 minutes after the lightning has stopped before going outside.
