Introduction
A man-made disasters is a disaster resulting from human intent, negligence, or error.
Manmade disasters can be both intentional and unintentional. It results in huge loss of life and property. It further affects a person's mental, physical and social well-being.
Reasons For Man-Made Disasters
There are multiple factor that may relate to manmade disasters
Ignorance
Unawareness
Illiteracy
Carelessly handling danger
Chemical
Weapons
Nuclear Disaster
Nuclear disaster are the types of disaster that falls in this category is nuclear bomb. When this occurs, it is often as a result of intent and the end results are even more catastrophic with a large percentage of those involved losing their lives.
Chemical Disasters/Industrial Disasters
By their nature, the manufacture, storage, and transport of chemicals are accidents waiting to happen. Chemicals can be toxic, and they may react, often explosively. The impacts of chemical accidents can be deadly, for both human being-environments.
Fire disasters
Bush fires, forest fires, and mine fires are generally started by lightning, but also by human negligence or arson. They can burn thousands of square kilometers
Deforestation
Forest is an
important source
for satisfying
people's demands
and needs.
Thus, undoubtedly
people would try to
exploit forest
resources. This
process of
exploiting forest is
called
deforestation.
1. One should not look at the fire as it causes instant blindness
2. Should close all doors and windows as radioactivity does not penetrate into solid structures
3. Cover all food and water
Nuclear Accidents:
Chemical Agents
1. Use protective equipment.
2. Give quick and correct self-
aid when contaminated.
3. Avoid areas where
chemical agents exist.
4. Decontaminate your
equipment and body as
soon as possible.
Fire Accidents
1. The biggest main reason might be poor wiring and faulty electrical equipment, leaking gas or carelessly thrown cigarettes and matches.
2. Wires should be properly covered.
3. Inflammable things should be kept safely.
4. Power points should not be overloaded.
Introduction
Chernobyl disaster is considered to be the worstcatastrophic (Manmade disaster) in history.Chernobyl was a nuclear power plant that waslocated 80 miles north of Kiev, which is now the‘Ukraine’. Chernobyl was a part of the city‘Pripyat’.
What Happened? On 26th April 1986, at 1:23 P.M. blast occurred
in the 4th reactor. The reactor 4 sufferedpower increase leading to explosion fromcore. The two engineers present in the 4th
reactor were Alexander Akimov and LeonidToptunov. Whereas Leonid was present atthe time of blast as he was a young engineerwith a 3 months experience.
How did it happen?
The obvious reason that can be stated is‘Operator error’. Maybe the operator was notexperienced enough to control the reactor.Another reason was that the, operator allowedto much water flow in the tank that caused thespeed of the turbine to increase uncontrollably.Additionally normal safety rules were notfollowed. Example the regulation required atleast 15 controlled rods but at the time of theexplosion there were on 10 rods intact.
The Chernobyl plant showed the RBMK design characteristics. Excessive supply of cold watch and the attachment of only 10 rods led to the explosion.

What happened then?
Soon after the blast the city Pirpyat was evacuated
immediately. There were 50,000 people living who
were forced to leave everything behind (Even
necessary belongings). Within hours after explosion
dozen of people fell ill and experienced
headache, metallic taste in
mouth, vomiting, uncontrollable fits. Within hours
Pripyat became a ghost city.
Effects of the explosion
With the emitting radiations a rise was seen in
health disorders. Disease like Thyroid
cancer, mental illness, rise in
abortion, various physical disability. The rate
of cancers are still at a rise and many cases
are reported every year with a certain
disability. Every year thousands of people die
in this manner.
Chernobyl today
27 years have passed but still the radiation level is
that area is so high that nobody will be able to
live there for 200 years. The whole area is sealed
by the Russian force and no individuals id
allowed to visit anywhere near the reactor. It is
said that the controller keys of reactor 4 still
remain untouched even after 27 years.
