Suggest three measures to protect ourselves from lightning.? ›

While lightning we should stay in a closed place preferably in a closed room or car. We should avoid taking shelter under trees or standing in an open field while lightning. Electric wire, telephone lines, and metal surfaces should never be touched while lightning.

Lightning rods (and the accompanying protection system) are designed to protect a house or building from a direct lightning strike and, in particular, a lightning-initiated fire.

Lightning is a sudden electrostatic discharge that occurs typically during a thunderstorm. This discharge occurs between electrically charged regions of a cloud (called intra-cloud lightning or IC), between two clouds, or between a cloud and the ground.

Lightning strikes dissolve unusable nitrogen in water and form a natural fertilizer which is absorbed by the roots of plants. Thus, lightning helps for nitrogen fixation. 2. Lightning also produces important gas called ozone which protects our planet from the harmful UV rays.

Fully enclosed buildings with wiring and plumbing are best. A hard-topped metal vehicle with the windows closed is also safe. Stay inside until 30 minutes after the last rumble of thunder. Sheds, picnic shelters, tents or covered porches do NOT protect you from lightning.

Stay off corded phones, computers and other electrical equipment that put you in direct contact with electricity. Avoid plumbing, including sinks, baths and faucets. Stay away from windows and doors, and stay off porches. Do not lie on concrete floors, and do not lean against concrete walls.

Don't stand in open fields. If you are caught in an open field, seek a low spot. Crouch with your feet together and head low. Don't sit or lie down – these positions provide much more contact with the ground, allowing a wider path for lightning to follow.

The safest location during a thunderstorm is inside a large enclosed structure with plumbing and electrical wiring. These include shopping centers, schools, office buildings, and private residences.

Lightning is a discharge of electricity. A single stroke of lightning can heat the air around it to 30,000°C (54,000°F)! This extreme heating causes the air to expand explosively fast. The expansion creates a shock wave that turns into a booming sound wave, known as thunder.

Lightning is a strong and fast discharge of electricity from a storm cloud to the ground, within the cloud, or to another cloud. Lightning forms due to the separation of electrical charges. As air and moisture rise, positive charges are carried to the top of the storm cloud.

In fact, lightning can heat the air it passes through to 50,000 degrees Fahrenheit (5 times hotter than the surface of the sun). When lightning strikes a tree, the heat vaporizes any water in its path possibly causing the tree to explode or a strip of bark to be blown off.

In nature, a lightning flash and the associated thunder occur at almost the same time in a thunderstorm. A person on the ground sees the lightning flash before hearing the thunder because light at a speed of around 300,000,000 meters per second travels much faster than sound which moves at 340 meters per second.

Contrary to popular belief, metal does not inherently attract lightning. Instead, height, shape, and isolation are the dominant factors in determining where a lightning bolt strikes. The taller, more pointed, and isolated a structure, the more lightning will be attracted to it.

There's no foolproof way to prevent lightning strikes on your home, but there are things you can do to minimize the damage.

The correct answer is Lightning conductor. A lightning rod or lightning conductor is a metal rod mounted on a structure and intended to protect the structure from a lightning strike. Copper and its alloys are the most common materials used in lightning protection.

The IEC 62305 standard covers the regulations required for the protection of equipment and structures from the effects of both direct and indirect lightning strikes.

The application of SPDs along with the current carrying components and interconnection of grounded building systems provides the complete package for a full lightning protection system to protect structure, people, and equipment within.
