• Precautions & Safety from Thunderclap/Lightning
• Myths & facts of Lightning/Thunderclap
• Medical Symptoms

3. Natural Disaster
A natural disaster is a major
adverse event resulting from
natural processes of the
Earth
3

4. Thunderclap(वज्रपात)
The clouds of opposite energy
in the sky keep blowing and
swirling from the air. They
collide in the opposite
direction. This friction
produces electricity which falls
to the earth.
Which causes harm.

11. Five Ways Lightning Strikes People

Above Animations Use Only For Educational Purposes

12. 1.Direct Strike
12
Direct strikes occur to victims who are in open areas
They are potentially the most deadly
The heat produced when lightning moves over the skin can produce
burns
the ability to survive any lightning strike is related to-
• Immediate medical attention,
•The amount of current moving through the body is also a factor

13. 2.Side Flash
13
Occurs when lightning strikes a taller object near the victim
and a portion of the current jumps from taller object to the
victim.
The person acts as a “short circuit” for some of energy in the
lightning discharge.
Side flashes generally occur when the victim is within a foot or
two of the object that is struck.
Side flash victims have taken shelter under a tree to avoid rain
or hail

14. 3.Ground Current
14
Anyone outside near a lightning strike is potentially a victim
of ground current.
The ground current affects a much larger area than the other
causes of lightning casualties, the ground current causes the
most lightning deaths and injuries
Ground current also kills many farm animals

15. 4. Conduction
15
Lightning can travel long distances in wires or other metal
surfaces.
Metal provides a path for the lightning to follow
Whether inside or outside, anyone in contact with anything
connected to metal wires, plumbing, or metal surfaces that
extend outside is at risk.
This includes anything that plugs into an electrical outlet,
water faucets and showers, corded phones, and windows and
doors.

16. 5. Streamers
16
Not as common as the other types of lightning injuries
People caught in “streamers” are at risk of being killed or injured by lightning
Streamers develop as the downward-moving leader approaches the ground

17. Lightning Safety Indoors
17
Stay off corded phones. You can use cellular or cordless phones.
Don't touch electrical equipment such as computers, TVs, or cords. You can use remote
controls safety
Avoid plumbing. Do not wash your hands, take a shower or wash dishes.
Stay away from exterior windows and doors that might contain metal components leading
from outside your home to the inside
Stay off balconies, porches and out of open garages or car ports
Do not lie on concrete floors or lean against concrete walls
Protect your pets: Dog houses are not safe shelters. Dogs that are chained to trees or on
metal runners are particularly vulnerable to lightning strikes.
Do not unplug equipment during a thunderstorm as there is a risk you could be struck

18. Lightning Safety Outdoors
18
Avoid open fields, the top of a hill or a ridge top.
Stay away from tall, isolated trees or other tall objects
If you are in a forest, stay near a lower stand of trees
If you are in a group, spread out to avoid the current traveling between group members
If you are camping in an open area, set up camp in a valley, ravine or other low area.
Remember, a tent offers NO protection from lighting
Stay away from water, wet items, such as ropes, and metal objects, such as fences and poles
Protect yourself when on a bicycle, motorcycle or dirt bike. If you see threatening skies in the
distance and you are near a safe building, pull over and wait 30 minutes after the last rumble
of thunder before resuming your ride.

19. Protecting Your Home
19
Lightning rods are designed to protect a house or building from a direct lightning strike
lightning protection systems do not prevent lightning from striking the structure, but rather
intercept a lightning strike, provide a conductive path for the harmful electrical discharge to
follow (the appropriate copper or aluminum cable), and disperse the energy safely into the
ground (grounding network).

20. First Aid for Lightning Strike
20
Call for help. Call your local ambulance service
Move the victim to an area of greater safety if necessary
The basic principle of triage ("treat the living first") should be reversed in patients struck by
lightning: those appear to be dead should be treated first
If the victim has stopped breathing, begin rescue breathing
If the heart has stopped beating, a trained person should give CPR
If the person has a pulse and is breathing, address any other injuries
For those victims who are unconscious and may be in cardiac arrest, CPR should be restarted

21. Lightning Myths & Facts
21
Myth: Lightning never strikes the same place twice
Fact: Lightning often strikes the same place repeatedly, especially if it's a tall, pointy,
isolated object
Myth: If outside in a thunderstorm, you should seek shelter under a tree to stay dry
Fact: Being underneath a tree is the second leading cause of lightning casualties
Myth: If you are in a house, you are 100% safe from lightning
Fact: A house is a safe place to be during a thunderstorm as long as you avoid anything that
conducts electricity
Myth: If trapped outside and lightning is about to strike, I should lie flat on the ground
Fact: Lying flat increases your chance of being affected by potentially deadly ground current.
If you are caught outside in a thunderstorm, you keep moving toward a safe shelter

22. Lightning Myths & Facts
22
Myth: If you're caught outside during a thunderstorm, you should crouch down to reduce your
risk of being struck.
Fact: Crouching doesn't make you any safer outdoors. Run to a substantial building or hard
topped vehicle. If you are too far to run to one of these options, you have no good alternative.
You are NOT safe anywhere outdoors.
Myth: If it’s not raining or there aren’t clouds overhead, you’re safe from lightning.
Fact: Lightning often strikes more than three miles from the center of the thunderstorm, far
outside the rain or thunderstorm cloud. “Bolts from the blue” can strike 10-15 miles from the
thunderstorm.
Myth: Rubber tires on a car protect you from lightning by insulating you from the ground.
Fact: Most cars are safe from lightning, but it is the metal roof and metal sides that protect
you, NOT the rubber tires. Remember, convertibles, motorcycles, bicycles, open-shelled
outdoor recreational vehicles and cars with fiberglass shells offer no protection from lightning.
When lightning strikes a vehicle, it goes through the metal frame into the ground. Don't lean
on doors during a thunderstorm

23. Medical Symptoms
23
Muscle soreness
Headache, nausea, stomach upset and other post-concussion types of symptoms
Mild confusion, memory slowness or mental clouding
Dizziness, balance problems
Problems coding new information and accessing old information
Problems multitasking
Slower reaction time
Distractibility
Irritability and personality change
Inattentiveness or forgetfulness
Headaches which do not resolve with usual medicine
Chronic pain from nerve injury
Ringing in the ears and dizziness or balance problems
Difficulty sleeping, sometimes sleeping excessively at first and later only two or three hours
at a time

When Thunder Roars, Go Indoors.
