Question 1.
What is disaster management ?
Answer:
Disaster management is the overall preparedness to handle the possibility of a disaster and efficient management of affected regions as well as people if such an incident were to occur. It involves plans and steps taken before, during and after a disaster to reduce the extent of suffering and damage.
Question 2.
Why is disaster management important ?
Answer:
A disaster – (natural or man-made) can strike anytime without warning. The disaster management is important because the geographical location and landscape of India exposes it to earthquakes and many kinds of weather- related disasters. In a developing country like India, usually the poor suffer the most.

Proper and prior planning can help in limiting and minimizing damages and losses resulting from any disaster – natural or man-made.
Question 3.
What safety measures can be followed against floods ?
Answer:
Floods can be prevented in vulnerable areas by properly maintaining dykes and embankments along rivers. The government and relief organisation must also have provisions of flood shelters in vulnerable places (along flood prone regions) so that people and livestock can be quickly evacuated and provided relief too. The government must also plan stationing rescue equipment near flood-prone areas. It should be possible to immediately deploy rescue boats and have communication lines open and functioning in order to rescue people caught functioning in order to rescue people caught in rising levels of water. There should be enough dry food, clean water and medicines made available to these people, affected by floods, so that spread of diseases can be stopped.
Question 4.

Answer:
Few safety measures against fire are :
1. Everyone should be acquainted with the common fire safety norms.
2. We should take some time out to find out about the different
kinds of fire extinguishers and the correct one to use in case of a fire. Fires are of different origins and we should make an effort to know more about this and the right extinguisher to use.
3. While entering a public place such a cinema hall or auditorium, we should make note of the fire exits and all other possible exits.
4. If a fire were to break out, we should avoid using the lift as a means of escape.
5. We should undergo training in first-aid in case of a fire and ways to put out flames.
6. If we light a matchstick to light a candle or the stove, we should also make sure that the matchstick is properly disposed of.
7. We should always turn off the knob of our LPG cylinders when it is not in use. We should also always keep a kitchen window open so that any inflammable gas can dissipate instead of accumulating in the kitchen.
Question 5.

2. Efficient forecasting and warning systems should be installed.
3. Modern tools of information technology must be used for managing such situations.
4. The government should set up organizations to coordinate relief work and give top priority to rehabilitation and reconstruction plans.
5. The communication network should be strengthened to ensure that entire regions do not get cut off in the eventuality of disasters like earthquakes and tsunamis.
6. Inspection team should be send regularly to check safety regulations at public places like hotels, malls, theatres, etc.
Question 5.
What role can people play in disaster management ?
Answer:
When a disaster occurs, the external aid comes late, so the people should be skilled in first-aid techniques and in ways to help other critically injured people. Every house should have a first -aid kit. There should be awareness about the disasters and preventions for them. For example, the hotel management could help save a lot of lives in case of a fire if it follows the government regulations on emergency exits, escape routes and fire extinguishers. The residents of a war zone may construct undergrounds bunkers that can protect them from air strikes by enemy nations. People living in areas prone to tsunami may plant more trees or create tsunami walls, along the coastline to prevent extensive damage. Also people should be alert to suspicious elements, such as terrorists, who are capable of launching attacks and causing man-made disasters.
