In general, emergency planning makes us more prepared for a disaster. Because we are more prepared, it is easier to act during the disaster and to recover from the disaster. This can be true on both the level of individual families and on the level of cities or states.
Emergency planning consists of having a series of plans in place that will dictate how we will act in the event of a disaster. For example, families can make emergency plans. They can make plans about where they will go if they are apart when a disaster strikes. They can ensure that all family members have copies of numbers for people to call. They can make sure that they have ways to communicate and that they have resources such as non-perishable food available to them at home.
Cities and states can participate in emergency planning as well. They can decide ahead of time which agencies will take care of which tasks. They can have predetermined refuges where people can go if their own homes are in danger or have been destroyed. They can have stockpiles of the sorts of equipment and supplies that would be needed in emergencies.
These actions make it easier to deal with the disaster and to recover from it. People will know where to go to find help. This will allow them to be safer during the disaster. Crews from governmental agencies will know what their missions are and where to find the things they need. This will allow for faster response to the disaster.
In these ways, emergency planning can help us deal more effectively with disasters and their aftermaths.
