What is Man Made Disaster?

 

A man made disaster is a disaster resulting from human intent, negligence, or error. They can be both intentional and unintentional. It results in a huge loss of life and property.

Fires can be caused by lightning or volcanic eruptions. It can also be caused by sparks from electrical appliances or wheels of the train.

 

Do you know, what is a disaster?

A disaster can be defined as a sudden, accidental event of great magnitude that causes considerable damage to life and property.

 

Let us learn about Fire Hazards.

 

Fire Hazards include all types of live flames, causes of sparks, hot objects, and chemicals that are potential for ignition. Fire hazard leads to a threat to life and property.

 

Forests Fires

 

Let us understand the causes of Forest Fire:

 

There are mainly four causes of forest fires. These are �

 

Natural � Fires are caused due to natural events such as lightning or volcanic eruptions.
Negligence - Fires caused by cigarette stubs along roadways or railway lines. Fires are also caused by agricultural and forestry activities such as the clearing of plant residue or for clearing the uncultivated land.
Accidental � Fires caused by sparks from wheels of trains or certain locomotives.
Arson - It is a crime of intentionally setting a fire in order to damage or destroy something (property). Such fires cause harm to wildlife by destroying their natural habitats.

 

Impacts of Forest Fires

 

Let us learn about the impacts of a forest fire.

 

� Forest fire destroys millions of hectares of vegetation and property. It affects food crops, transport, and tourism.
� The smoke and smog produced during forest fires decrease the amount of sunlight and also induce respiratory problems among human beings and wildlife.
� Large fire events can also create acid rain conditions that damage the forest habitat. It also releases a large number of greenhouse gases that cause global warming and climate change.
� Forest fires have an impact on insects and fruit trees. It disrupts the food chain for predators and other species.

 

Fire in Buildings

 

The main cause for the fire hazards in buildings are �
� Room heaters and fireplaces within the room.
� Poor electric wiring and loose connections.
� Sometimes smoking may cause a fire.
� The storage of hazardous chemicals.
� It can also originate from the kitchen where there is a mechanical failure of the cooking equipment.

 

Fire Safety Measures

 

Fire safety is the set of practices intended to reduce the destruction caused by fire. It will also help your family to quickly escape a fire.

 

Let us learn about some fire safety measures.

 

Put smoke alarms or detectors in strategic locations in the home.
Keep a fire extinguisher near the kitchen. Childers should be taught safety rules for matches, fires, etc.
Avoid fireworks.
Make sure that the cigarette should be fully extinguished. Keep an eye on anything while you are cooking or using anything that can cause a fire.

 

Industrial and Nuclear Accidents and Terrorism

Industrial accidents occur due to dangerous procedures, infrastructures failures, explosions, etc. The most common of these industrial accidents is the leakage of harmful gases and explosions.

 

Industrial and Nuclear Accidents

 

Do you know, how industrial accidents occur?

 

Industrial accidents occur due to dangerous procedures, infrastructures failures, explosions, and pollution caused by the discharge of harmful chemicals into air or water bodies. These accidents are also caused due to the explosions or leakage of harmful gases. The leakage of harmful gases or the gases that are released due to explosion affects the environment as well as human life.

 

Let us learn about some of the industrial and nuclear accidents.

 

Have you heard about the Bhopal Gas Tragedy?

 

The Bhopal Gas Tragedy was one of the deadliest man made disaster related to gas leakage that occurred on the night of 2 - 3 December 1984. It occurred due to the leakage of methyl isocyanate gas into the atmosphere at Union Carbide India Limited (UCIL) pesticide plant in Bhopal. It is considered to be the world�s worst industrial disaster. The leakage of gas engulfed the city, it resulted in the loss of sight and breathlessness.

 

Another industrial disaster happened due to the massive explosion at a warehouse where hazardous chemicals were stored in the Chinese port of Tianjin in August 2015.

 

Do you know, how a nuclear accident occurs?

 

A nuclear accident occurs when radioactive material and nuclear radiation are discharged into the atmosphere caused by an explosion in the nuclear reactor or leakage.

 

The world�s worst nuclear accident occurred at Chernobyl, Ukraine on 26 April 1986. On this day, a reactor at the nuclear power complex exploded. It happened because of a meltdown in a reactor due to which a massive amount of radioactive gases releases into the atmosphere. There was high radioactive fallout in Poland, Germany, Sweden, Norway, Finland, and Italy.

 

Terrorism

 

What do you mean by terrorism?

 

Terrorism is the use of intentional violence for political or religious purposes. Terrorists use indiscriminate violence as a means to create terror among people to achieve political, religious, ideological, or financial goals. Terrorists often implant bombs in dustbins, lunchboxes, baggage, etc.

 

One of the major and fatal terrorist attacks happened on 11th September 2001when terrorists hijacked airplanes and used them as a weapon to destroy the twin towers of the World Trade Centre in New York, USA.
