 Introduction
 Types of Disasters,
 Hazards,
 Disaster Management,
 Personal Protection in Different Types of Emergencies,
 Man Made Disasters

3. DISASTER
 The United Nations Office for Disaster Risk Reduction (UNISDR)
(2009) defines disaster as:
"A serious disruption of the functioning of a community or a society
involving widespread human, material, economic or environmental
losses and impacts, which exceed the ability of the affected community
or society to cope using its own resources".
3

4. DISASTER
 The Disaster Management Act 2005 of India:
"Disaster means a catastrophe, mishap, calamity or grave occurrence in
any area, arising from natural or manmade causes, or by accident or
negligence which results in substantial loss of life or human suffering or
damage to, and destruction of property, or damage to, or degradation of,
environment, and is of such a nature or magnitude as to be beyond the
coping capacity of the community of the affected area"

5. HAZARD
 As per the definition adopted by UNISDR,
 "hazard" is a dangerous phenomenon, substance, human activity, or
condition that may cause loss of life, injury or other health impacts,
property damage, loss of livelihoods and services, social and
economic disruption, or environmental damage.
 India , due to its physiographic and climatic conditions is one of the
most disaster prone areas in the world.

6. TYPES OF DISASTERS
1. Natural hazards
2. Human-induced
NATURAL HAZARDS:
 Classified based on Disaster Information Management System of
Deslnventar into 5 major categories (Deslnventar 2016).
 1. Geophysical – earthquakes, volcanos, tsunami
 2. Hydrological – Flood, landslides (Avalanche, debriflow, mud flow,
rockfall), Wave action - Wind generated surface waves of water over
oceans, rivers or lakes.
 3. Meteorological: Cyclone, storm surge, tornado, high wind 6

7.  (b) Cold wave
 (c} Extreme temperature, fog, frost, freeze, hail, heatwave
 (d) Lightning, heavy rain (e) Sand-storm, dust-storm
 (f) Snow, ice, winter storm, blizzard
4. Climatological :
 (a) Drought (b) Extreme hot/cold conditions
 (C) Forest wildfire (d) Glacial lake outburst
 5. Biological:
 (a ) Epidemics: viral, bacterial, parasitic, fungal or prion infections
 (b) Insect infestations 7

8. B. HUMAN-INDUCED DISASTERS
 The rise in population, rapid urbanization and industrialization,
environmental degradation, and climate change aggravates the
vulnerabilities to various kinds of disasters
 - (industrial, road, air, rail, on river or sea, building collapse, fires, mine
flooding, oil spills, etc.).
 - Chemical, biological, radiological, and nuclear (CBRN) hazards.
 Terrorist activities, Warfare.
 Some can be predicted several hours or days before-hand, as in the
case of cyclones or floods, others such as earthquakes occur without
warning.
8

9.  The relative number of injuries and deaths differ, depending on
various factors such as the type of disaster, the density and
distribution of the population, condition of the environment, degree of
the preparedness and opportunity of the warning.
 Injuries usually exceed death in explosions, earthquakes, typhoons,
hurricanes, fires, tornadoes etc.
 Death frequently exceeds injuries in landslides, avalanches, volcanic
eruptions, tidal waves, floods etc.
9

10. 10

11.  On the whole, morbidity which results from a disaster situation can be
classified into four types :
a. Injuries;
b. Emotional stress;
c. Epidemic of disease; and
d. Increase in indigenous diseases.

14. FUNDAMENTAL ASPECTS OF DISASTER
MANAGEMENT
 Disaster response; Most injuries are sustained during the impact, thus
the greatest need for the emergency is in the first few hours. help to
the affected people.
 Disaster mitigation; lessen the effect of disaster.
 Disaster preparedness; ensuring appropriate systems, procedures
and resources are in place to provide prompt effective assistance to
disaster victims.

1.Impact area: where disaster has struck
causing maximum damage.
2.Filter area: undamaged area surrounding
impact area from where immediate aid starts.
3.Community aid area: outside filter area from
where organized rescue &relief flows.

17. DISASTER IMPACT AND RESPONSE
Search, rescue and first aid
 Should be the immediate response.
 Most immediate help comes from the uninjured survivors.
Field care
 Health service resources be redirected to this new priority.
 Bed availability and surgical services should be maximized.
 Food and shelter should be provided.
 Victim identification.
 Adequate mortuary space should be provided. 17

18. IDENTIFICATION OF DEAD

19. TRIAGE
 It is the process of prioritizing the patient based on the severity of their
condition.
 Black- Morgue(No pulse / No breathing)
 Red- High priority(life threatening but requires simple intensive
care)
 Yellow- Moderate priority(serious non life threatening)
 Green- Mild priority(walking wounded)
 Tagging – all patients should be identified with tags stating their name,
age, place of origin, triage category, diagnosis and initial treatment.

22. RELIEF PHASE
 The immediate requirements are ;
 Critical health supplies for treating casualties and preventing the
spread of communicable diseases.
 Supply of food, blankets, clothing, shelter, sanitary engineering
equipment and construction material.
 Rapid damage assessment is done in order to identify needs and
resources.
 There are four principal components in managing humanitarian
supplies :
- (a) acquisition of supplies; (b) transportation; (c) storage; and (d)
distribution. 22

23. RELIEF PHASE CONTD..
23

24. EPIDEMIOLOGICAL SURVEILLANCE AND DISEASE
CONTROL
 Disasters increase the transmission of communicable diseases due to
poor sanitation, migration, contamination of water etc.,
 Preventing and controlling communicable diseases after disaster are
to-
 - Implement public health measures
 - Organize disease reporting system to identify outbreaks and to
promptly initiate control measures.
 - Investigate all reports of disease outbreak rapidly.
24

25. VACCINATION
 Usually given against typhoid, cholera and tetanus due to public and
political pressure.
 WHO does not recommend typhoid and cholera vaccine- supplying
safe drinking water and proper disposal of excreta is the most
effective strategy.
 If the patient with open wounds has received tetanus immunization 5
years ago then a tetanus toxoid booster dose is an effective
preventive measure.
25

26. NUTRITION
 Immediate steps.
 Assessing food supplies after the disaster.
 Gauging the nutritional needs of the affected population.
 Calculating daily food rations and need for large population groups.
 Monitoring the nutritional status of the affected population.
26

27. REHABILITATION
– final phase in a disaster response which leads to the restoration of
pre-disaster conditions(normal living). It includes;
 Starts from the very first moment of the disaster
 Causality care to primary health care
 Priorities shift from health care towards environmental health
measures
- Safe water supply
- Food safety
- Basic sanitation and personal hygiene
- Vector control
27

28. DISASTER MITIGATION
-involves either to prevent hazards causing emergency or to lessen the
effects of emergencies.
E.g.
 Flood mitigation works,
 Appropriate land-use planning
 Improved building codes for earthquakes
 Planting trees in the coastal areas
 Japan has built many tsunami walls of up to 4.5 metres (15 ft) to
protect populated coastal areas.
 Other localities have built floodgates and channels to redirect the
water from incoming tsunami
 Protection of vulnerable population and structures 28

29. BUILDING HOUSES THAT STAND EARTH QUAKE IS AN
EXAMPLE OF DISASTER MITIGATION.

31. DISASTER PREPAREDNESS
 It is a program of long term development activities whose goals are to
strengthen the overall capacity and capability of a country to manage
efficiently all types of emergencies.
 Objective:
- To ensure that appropriate systems, procedures and resources are in
place to provide prompt and effective assistance,thus facilitating relief
measures and rehabilitation of services
31

32. PERSONAL PROTECTION IN DIFFERENT TYPES
OF EMERGENCIES
 A number of measures must be observed by all persons in all types of
emergency:
- Don’t use telephone, except to call for help, to leave telephone lines free
- Listen to the messages broadcast by radio and the various media so as to
be informed of development.
- Carry out the official instructions given over the radio or by loudspeaker.
- Keep a family emergency kit ready.
 In all the different types of emergency, it is better:
- to be prepared than to get hurt;
- to get information so as to get organized;
- to wait rather than act too hastily
32

33. A. FLOODS
BEFORE-HAND DURING AFTER
1. Town planning
2. watching the water level
3. listening to the weather forecasts
4. hurricanes and cyclones often
occur at the same time of year,
therefore vigilance to be kept
5. They are often announced
several hours or days before they
arrive.
1. Turn off the electricity to reduce
the risk of electrocution.
2. Protect people and property:
3. Take vulnerable people to an
upper floor;
4. move personal belongings
upstairs or go to raised shelters
provided for use in floods .
5. Beware of water contamination -
if the taste, colour, or smell of the
water is suspicious, it is vital to
use some means of purification.
6. Evacuate danger zones as
ordered by the local authorities it
is essential to comply strictly with
the evacuation advice given.
1. do not return home until told to do
so by the local authorities, who
will ensure that buildings have not
been undermined by water.
2. wait until the water is declared
safe before drinking,
3. clean and disinfect room that has
been flooded;
4. sterilize or wash with boiling
water all dishes & kitchen
utensils;
5. get rid of any food that was near
the water, including canned foods
and any food kept in refrigerators
and freezers;
6. get rid of all consumables (drinks,
medicines, cosmetics, etc.

D. CLOUDS OF TOXIC FUMES

38. MAN-MADE DISASTERS
 These can be three categories. (a) SUDDEN DISASTERS
1. Bhopal Gas Tragedy in India on 3rd December 1984
 Leakage in the storage tank of Union Carbide Pesticide Plant released tons
of methyl isocyanate into the air.
 Wind conditions and an atmospheric inversion, along with delayed warning
and a population that had not been taught the nature of risks and the
appropriate response increased the impact.
 About 2 million people were exposed to the gas leaving about 3,000 dead.
2. The accident at reactor 4 of the Chernobyl nuclear power station in the
Soviet Union on April 26, 1986,
 resulted in the largest reported accidental release of radioactive material in
the history of nuclear power.
 It deposited more than 7 million curies of Iodine 131, Cesium 134 and 137,
Strontium 90 and other isotopes throughout the northern hemisphere
38

39. (B) INSIDIOUS DISASTERS
 Insidious chemical exposure and insidious radiation exposure, as in
nuclear weapons production factories , research laboratories resulting
in release of radioactive substances into the air, soil and underground
water.
 Chemical plants releasing their toxic by-products into rivers and other
water sources is another example.
 Other form of long term and continuing human-made disaster include
global warming (the "green house effect")
39

40. (C) WARS AND CIVIL CONFLICTS
 The latest example is the attack on twin buildings of World Trade
Centre in New York in which about 6000 people lost their lives and
thousands were injured.
40

41. DISASTERS IN INDIA
 With a wide range of topographic and climatic conditions, India is the
highly disaster-prone country in Asia-Pacific region with an average of
8 major natural calamities a year.
 While floods, cyclones, draughts, earthquakes and epidemics are
frequent from time to time, major accidents happen in railways, mines
and factories causing extensive damage to human life and property.
41

42. DISASTERS IN INDIA
 Orissa: super cyclone on 29th October 1999, thousands lost their lives
and many more became homeless.
 Gujarat: severe earthquake ,16,480 people died and lakhs became
homeless.
 Indian ocean tsunami: killed >200,000 persons in India in Dec. 2004
 major earthquake in Jammu & Kashmir (7.4 RS) left 2 ,100 dead and
30,000 injured,
 June 2013 in Uttarakhand, cloudburst causing floods that killed about
5,748 people in Kedarnath, and the floods in Kashmir vally in 2014.
 More recently, floods in Karnataka 2019,India.
42

43.  In the federal structure of India, the state governments are responsible
for the execution of relief work in wake of natural disasters.
Government of India plays a supportive role, in terms of
supplementation of final resources to the states.
 An administrative system has been developed to combat and
minimize the adverse impact of the natural disasters.

The National Disaster Management Authority (NOMA) is the lead
agency responsible for the preparation of Disaster Management (OM)
plans and the execution of OM functions at the national level.

45.  In a vast country like India, it is not practicable for the government
machinery alone, to undertake disaster reduction programmes without
involvement of NGOs.
 Public education and community involvement plays a vital role here.
 As part of the International Decade for Natural Disaster Reduction
activities, every year, the second Wednesday of October has been
designated as World Disaster Reduction Day.
45

46. INDIAN METEOROLOGICAL DEPARTMENT (IMD)
 Plays a key role in forewarning the disaster.
 5 centres: Kolkata, Bhubaneshwar, Vishakhapatnam, Chennai and
Mumbai
 Satellite imagery facilities and cyclone warning radars are provided to
various Cyclone Warning Centres.
 For all ships out at sea, warnings are issued six times a day.
 Insat Disaster Warning System (DWS) receivers have been installed
primarily in the coastal areas of Tamil Nadu and Andhra Pradesh.
 The Snow and Avalanche Study Establishment (SASE) in Manali:
issues warning to people about avalanches 24 to 48 hours in
advance.
