TYPES OF MAN MADE DISASTERS

FireCauses Of FireThe most common causes of fire are:ElectricalPantry AreaSmoking

Classes Of FireLet us also understand the classes of fires.

Class AThese are fires that involve some solid material like, clothers, paper,

junk-heap, wood etc.

Class BThese are fires that involve liquid materials like: petrol, gasoline,

diesel, oil etc.Class CThese are fires that involve electrical elementsClass DThese are fires are those involve metals

Explosion

An explosion is a rapid increase in volume and release of energy in an extreme manner, usually with the generation of high temperatures and the release of gases.

 Supersonic explosions created by high explosives are known as detonations and travel via supersonic shock waves. 

Subsonic explosions are created by low explosives through a slower burning process known as deflagration.

A chemical threat is fear of a release of poisonous vapors, aerosols, liquids, and solids being dispensed into the air or water ways which would have a toxic effect on people, animals, and/or plants

A chemical threat

Chemical agent or chemical poisons are primarily used in war, terrorism and riot control.

The impacts of chemical accidents can be deadly, for both human being-environments.

Nerve AgentsBlister or Vesicant AgentsChoking Agents

Types of Chemical Warfare Agents

Depending upon the type of chemical, it can either have an immediate effect (seconds to minutes) or a delayed effect (2-48 hours).

Nuclear disaster

Nuclear power plants use the heat generated from nuclear fission in a contained environment to convert water to steam, which powers generators to produce electricity. It is the by-product of this activity that creates the biggest hazard.

Accident categoriesNuclear meltdownCriticality accidentsDecay heatEquipment failureHuman error

Nuclear DisasterThis 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.

Precautions for man made disasters

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 Accidents1. 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.

Historical Examples of man made disasters

1. London’s Killer Fog

2. The Al-Mishraq Fire

3. Dioxin Pollution
