The survey of building/ home/ school regarding disaster management is necessary and a PLAN needs to be prepared regarding the same to ensure prior safety. While preparing the plan one needs to see to it that the plan prepared has a HOLISTIC approach to combat any disaster. A written description of the school and its surroundings shall provide a basis for identifying hazards to which the school might be exposed. Once the hazard has been identified, it becomes possible to develop preparedness, prevention and a response programme to minimize them. Not all EMERGENCIES can be prevented. Therefore, the plan needs to describe arrangements for responding to those emergencies that do occur/are at a greater chance of occurring. It shall describe KEY ROLES and responsibilities including who will be responsible for coordination, control and communication when responding to an emergency.Explanation:I Hope U R Crystal Clear With Ur Question...
